8 tips for staying healthy on a college campus 

Between classes, exams, parties and a host of new responsibilities, finding time for your health in college can seem impossible. But even with all the new stresses and obligations, keeping healthy habits doesn’t have to be hard. So grab your notebooks (read: laptops) and get ready to take notes, because here are 8 tips to keep you healthy this semester. 

  1. Choose nutrient-rich foods

With a full day ahead, it’s easy to grab a cup of coffee on your way out the door and call it breakfast – and the same might even go for lunch. It might seem like saving this time will make you more productive, but in reality, skipping meals impacts your mental clarity – and gets in the way of getting things done. 

Or maybe it’s the opposite: College life offers a lot of eating options, and it can be tempting to indulge in the dining hall’s all-you-can eat buffet, skipping fresh fruits and veggies in favor of fatty processed foods, but this can make you sluggish and lead to unwanted weight gain. Prioritizing a balanced diet packed with fruits, vegetables, whole grains and lean meats can help keep your mood up and your brain sharp so you can power through that study guide.  

  1. Guzzle water and carry a refillable bottle

In college, three key beverages can easily become staples in your diet: coffee, energy drinks and alcohol. While powering through on sugar and caffeine might seem like a good option, leaning too hard on these drinks can lead to bad habits and long-term health issues. A better solution? Water. It seems simple, but it’s essential to health, and so many of us don’t drink enough. Water cleanses your body and transports nutrients to your cells for energy. It will also improve your skin, boost your concentration, and keep you from overeating. Aim to drink about half a fluid ounce for every pound of body weight each day. If water is a struggle for you, try carrying your water bottle with you everywhere you go; it’s the easiest way to make it a habit. 

  1. Remember to sleep

If sleep is scarce for you, it’s time to prioritize your zzz’s. You might feel the need to pull regular all-nighters, but lack of sleep can lead to brain fog, making it harder to concentrate on your studies. Sleep allows your body to rest and restore, helping improve your productivity the next day. Aim to get at least 7 hours of sleep each night. If there are nights that you do stay up late, try to schedule a 20-minute catnap in your breaks to help refresh your mind. 

  1. Exercise and enjoy

Staying active in college can lower your stress levels, improve your mood, increase energy and strengthen your heart. You might think you need to pencil in a one-hour sweat session every day to get all the benefits, but that’s not true. Just keep moving and stretching as much as possible: Go on a run around campus, hit the gym with your friends or even join a club to stay motivated.  

  1. Keep healthy dorm snacks on hand

That sleeve of cookies might give you a quick spike in energy, but it won’t last long. Sugar crashes can wreak havoc on your body—leading to poor mood and making it harder to focus. Rather than reaching for sugary, calorie-laden snacks, keep nutritious options on hand. Stashing fruit, nuts or granola in your bag or dorm room will give you longer-lasting energy and is better for your health. 

  1. Practice good hygiene

Between classes, study groups, dorm rooms and parties, you’re continuously in close contact with hundreds of your peers, making it easy to catch a cold. If you don’t want sickness to keep you out of class, one of the best things you can do is to wash your hands regularly. Just think about all the germ-infested things you touch daily (…err, maybe don’t think about it too hard!). Wash your hands often and carry a bottle of hand sanitizer in your bag for the times when you can’t get to soap and water. 

  1. Don’t forget self-care

College is stressful, but it’s also a time for fun and finding yourself—so make the most of it! Make time for the things you enjoy and commit to a self-care routine. There’s enough time to pack in work and play, so slather on a face mask, run a bubble bath and watch your favorite TV show! 

  1. Fill gaps with supplements 

Sometimes, even if we try to do everything right, we can use a little more help. Supplements can help fill nutritional gaps and support your body to function optimally. But remember: they should be used to complement a healthy diet and lifestyle—not replace it.

5 foods to boost your mood 

It’s normal for the occasional lousy mood to leave you elbow deep in a bag of chips (no judgement here). When we’re feeling sour, it’s natural to reach for sweets, a salty snack or some other comfort food. But while these tasty treats might help you fight off a case of the hangry-s, they don’t do a lot for your long-term happiness. Luckily, there are certain foods that can help you keep those blahs at bay for the long haul. If you’re done with that post-donut downswing, this is a list you’re going to want to keep on lock.  

1) Oatmeal  

Looking to start your morning with a little pep in your step? Oatmeal delivers a one-two punch to keep your mental health in check. It’s chock full of l-tryptophan, an amino acid your body uses to make serotonin, your brain’s feel-good hormone. It also contains a hearty dose of fiber, which is linked to a healthy gut. And you know the classic saying: happy gut, happy life, right? Having healthy bacteria in your gut may leave you less likely to have certain mood-related disorders.  

2) Red Peppers 

Roasted, stuffed, or chopped up in a stir fry, this tasty veggie is a total crowd pleaser—and not just because it can be tossed into basically any dish. Thanks to their high vitamin C content, red peppers may help give your mood a little lift. While the particulars aren’t well understood, your brain uses vitamin C for many biological processes, and it’s been linked to quicker recovery from mental stress and a positive mood.    

3) Blackberries  

That summer blackberry crumble is doing more than satisfying your sweet tooth. Blackberries are rich in antioxidants like anthocyanins and flavanols that play a role in mood regulation. High intake of berries has been associated with a positive effect on mood and may even play a role in working memory. Add some berries to your yogurt or try throwing frozen berries in a smoothie.    

4) Salmon  

Salmon is a great source of vitamin D, a hormone-like vitamin that plays a role in mood regulation. One palm-sized filet of farmed Atlantic salmon (about 3.5 oz) contains roughly 66% of your daily needs. While eating vitamin D-rich foods, like salmon, isn’t going to give you an instant bump, getting your daily dose has been associated with a reducing negative moods in some people.  

5) Jerusalem Artichokes 

This nutty, creamy root vegetable makes an excellent mash that might even bring a smile to your face—literally! Jerusalem Artichokes contain inulin, a type of fiber that works like food for the healthy bacteria in your gut. Unlike other nutrients that work over a longer period of time to support a positive mood, inulin may help provide an instant mood lift.

5 surprising benefits of omega-3

From the beating of your heart to the buzzing of your brain to the building of bulging muscles, omega-3 plays a starring role in functions throughout your body. But despite the importance of this celebrity nutrient, more than two-thirds of adults aren’t getting enough. So just what can omega-3 do for you? And how do you make sure you don’t miss out? We dove into the science and endured the fish burps to get you some straight answers (hint: if dewy skin is on your agenda, you’re going to want to keep reading).  

What exactly is omega-3? 

Omega-3 is a type of healthy fat known as an unsaturated fat. It’s also an essential nutrient, meaning you can only get it through diet—mainly seed oils and fatty fish—because your body can’t make it from scratch. There are several kinds of omega-3, but only three that come with health benefits: DHA, EPA and ALA. These three omega amigos work hand-in-hand to help your body in five key ways: 

1) Heart Health  

Omega-3’s are a staple of a heart-healthy diet. And for good reason. Diets high in fish—a rich source of omega-3—have been linked to a lower risk of heart disease, the number one cause of death in the United States. Researchers believe this comes from the role omega-3 plays in increasing good cholesterol and decreasing artery-clogging fats called triglycerides. In other words, it seems to balance your body chemistry in a way that helps keep your blood vessels clear. Got your heart set on adding more seafood to your diet? Skip the fried stuff and opt for heart-friendly broiled, grilled or baked preparations.    

2) Brain power  

Nothing says healthy breakfast like eggs and… a tuna sandwich? Hear us out. Omega-3 is excellent brain fuel. It’s found throughout your brain cells, and low levels in the blood have been linked to challenges with learning and memory. Omega-3 intake may even influence the structure of your brain. Diets high in fish have been linked to higher levels of gray matter—the part of the brain that is involved with executive function. While scarfing down seafood isn’t necessarily going to make you smarter, getting enough omega-3 in your diet can help keep your brain in tip top shape.   

3) Smoother skin  

Is omega-3 the secret to glowing skin? It just might be. Omega-3 boasts photoprotective properties, meaning it might help protect your skin against sun damage. Since repeated sun exposure can breakdown collagen and lead to premature wrinkles and fine lines, any amount of sun protection is a huge win when it comes to maintaining a youthful glow. What’s more? Omega-3 can influence your skin’s hydration and support your skin barrier, making it one of the most beautifying nutrients that you can put on your plate (or in your face mask).   

4) Muscle recovery  

If you’re a regular gym rat or a trail junky you know how important it is to recovery from a workout. Omega-3 plays a role in your body’s ability to recover after a workout. During exercise, your muscles get tiny microscopic tears that need to be repaired later. The continual breakdown and repair of your muscle tissue is what leads to muscle growth. Although the jury is still out, omega-3 may help your muscles recover faster and even reduce normal muscle soreness after exercise. Keep your training on track by eating seafood 2x per week.     

5) Prenatal health 

Omega-3, specifically DHA, is key for a developing brain. The need starts during pregnancy and continues throughout your little one’s childhood. It’s so important, in fact, that women’s bodies have developed a special way to make sure a developing fetus is getting enough. Under normal circumstances, our bodies can make small amounts of DHA from another type of omega-3 fatty acid called ALA. During pregnancy, this process becomes even more efficient, giving the baby an extra boost. So, while it’s critical to eat sources of DHA throughout pregnancy, your body has an amazing way to fill in some gaps.    

How do you get omega-3 from your diet? 

So how can you cash in on the perks of this essential nutrient? Cook with seed oils like flax or olive oil for a good source of ALA. To cover your DHA and EPA needs, try eating seafood (think: oily fish like cod, tuna and haddock) at least two times per week. If seafood isn’t your thing- a supplement like krill, fish or algal oil might help fill the gaps.

5 supplements to pack for back-to-school  

The end of summer is bittersweet. The season of being carefree and spending long hours at the beach feels too short, but the start of a new school year has excitements of its own – new friends, memories and courses. As you shift focus back to study mode and set new goals, be sure to spare a thought for your nutrition. Afterall, you need to feel well to study well! Taken together with a healthy lifestyle, supplements can give your body the support it needs to really thrive. Here are 5 we recommend packing with you this school year. 

1. Get your ABCs with a multivitamin  

Your nutrition might seem like a low priority next to looming exams, but what you eat can actually impact your studies. It’s always best to get most of your nutrients from food, but if you don’t have time to prep balanced meals every day, a multivitamin can work well to fill potential gaps. It’ll help ensure you’re getting key vitamins like vitamin A to support your eyes, B-vitamins for energy and vitamin C to help with immunity.   

2. Omega-3s: no fishy benefits  

Interesting fact: your brain is nearly 60% fat,1 so it only makes sense that it needs omega-3s to work properly. If you’re unfamiliar with omega-3s, they’re essential fatty acids that your body can’t produce itself, meaning you need to get them from food or supplements. What do they do? A lot. They play a part in the health of your skin, eyes, heart, immunity and–—importantly for school—your brain. Omega 3s aid in the growth of brain tissue and the flow of oxygen to your brain, supporting mood, learning, memory and your brain’s overall health.2 Fatty fish like salmon, mackerel or cod are good sources, but if you’re not down to eat fish at least twice a week, it’s best to add a supplement to be sure you’re getting enough. 

3. Probiotic for a healthy microbiome  

You probably know probiotics support your digestion and help keep you regular, but you might be surprised by how important they are for your overall health. Ever notice when your digestion is off, your mood takes a turn too? Or when you’re feeling nervous, you suddenly have digestion issues? That’s because your gut and your brain communicate constantly, a phenomenon that impacts your mood and your ability to focus. In other words, a thriving gut equals a thriving mind. But that’s not all: About 70% of your immune system is in your gut too. The bacteria in your digestive tract help stop harmful microorganisms from entering your blood stream. Taking probiotics alongside a healthy diet, regular exercise, good hygiene and healthy sleep can help keep those tiny defenders up to the challenge.  

4. Vitamin D: the sunshine vitamin   

You’ve likely heard it before: get into the sun for 15-30 minutes a day to re-up your body’s vitamin D. This is because it’s a vital nutrient that acts like a hormone, playing a role in the health of your brain, bones, mood, energy and immune system. But even though it’s famously important and easy to produce from the sun, about 42% of Americans don’t get enough.3 That’s because unlike a lot of other key vitamins, vitamin D doesn’t occur naturally in a lot of foods. So, as we transition to the colder months, it may be best to add a supplement to your diet to keep your vitamin D in a healthy range. 

5. Manage stress with ashwagandha  

With a calendar full of project deadlines, exams and endless assigned reading, a stress-soothing aid definitely appeals. Ashwagandha is a super root that helps manage stress by regulating cortisol, your main stress hormone. If left uncontrolled, this infamous hormone can wreak havoc on your mind and body, leading to brain fog, mood shifts, weight gain and more. Ashwagandha can help contain these issues. Bonus: It also promotes calmness, relaxation and better sleep.

4 supplements to keep your brain sharp 

With the constant distractions of daily life and our never-ending to-do lists, it’s no wonder we’re all looking for ways to boost our brains. While diet and lifestyle are clearly vital on this front, there’s a growing body of evidence that supplements may also play a role. Today, we’ve rounded up our top four picks, based on the latest science. If you’re looking for ways to keep your brain in tip top shape, they may be worth a look. 

1) Omega-3 

Omega-3, a type of unsaturated fatty acid, comes with a host of health benefits—one of which is keeping your mind sharp. Why do we believe this? Because higher levels of omega-3 in the blood have been linked to a higher volume of gray matter in the brain1, the region where mental processing happens. More gray matter means more capacity for executive functions, the more complex tasks your brain carries out day to day (like reading this blog!). Surprisingly—and despite the plethora of Chia seed pudding recipes on the internet—68% of adults aren’t getting enough of this essential nutrient.2 Smarten up your diet by eating fish, nuts or seed oils like flax. If fish and nuts aren’t your thing, a supplement can help fill the gaps.  

2) Ginkgo 

As you age, it gets harder for your brain to store and recall memories. Ginkgo, a plant that has long been used for its anti-aging properties, may help combat this natural decline by supporting concentration, working memory and executive functioning.3  It’s thought to do this in two ways: by boosting blood flow to your brain and by acting as an antioxidant, combatting free radicals that can damage your brain cells. If you’re shopping for a Ginkgo supplement, look for Ginkgo Biloba extract as the main ingredient.  

3) Probiotic  

Probiotics are typically associated with gut health, but certain strains might play a role in your mental health as well. As your brain ages, your neuropathways decline. To put it in non-sciencey terms: Learning new things gets harder. Probiotics might help you resist this process4. But before you start scarfing down kimchi and kombucha, make sure you’re eating the right thing. Different strains of probiotics have different benefits—and only some support mental functioning. Bifidobacterium longum NCC3001 is one that shows promise, but more research is needed. So stay tuned!   

4) Phosphatidlyserine 

Phosphatidlyserine (PS) is an ingredient that’s as brainy as it sounds. It’s a type of fatty acid that occurs naturally in your brain cells, and is associated with cognitive function. You can find PS in foods like soy and chicken liver, but your body may not absorb it well. Since PS supplements are easier for your body to process, they may do more to support your memory and fend of age-related cognitive decline5.

5 tips to keep your brain healthy 

It’s no secret that with age, your body and mind start to slow down. But while it’s natural to have some trouble remembering or learning new tasks in later life, you aren’t powerless in the face of decline.

A few important lifestyle changes can go a long way to keeping your brain healthy and strong as you start to get on in years. 

1. Feed your brain a nutritious diet 

A well-balanced diet is the foundation of brain health. Certain nutrients like zinc, selenium and folate help you build new neurons —brain cells—that can improve focus, thinking and overall wellness. Meanwhile, foods rich in B-vitamins will similarly support your brain processes and help you develop neurotransmitters, chemicals that deliver messages between neurons and your body.

And good fats like omega-3s promote a healthy inflammatory response that can improve the flow of blood and oxygen to your brain.1 So how do you get all these nutrients in your diet?

There’s no one-size-fits-all solution out there, but focusing on fruits, veggies, whole grains, lean proteins and healthy fats from fish or avocados —and limiting sugar and saturated fats—is a pretty smart bet.2 

2. Get moving 

You already know that exercise is good for you—it helps strengthen your bones, muscles, immunity and much more—but did you know breaking a sweat also helps keep you sharp?

A good rule of thumb is: If it’s good for your heart, it’s good for your brain. Working out a few times a week for about 30 minutes can increase blood flow and oxygen to your brain, leading to the creation of new neurons and better brain function.

And there’s no reason to think your activities need to be extreme; even a walk around the block will help!  

3. Challenge yourself 

Just as exercising your body is important, so is exercising your mind.

Learning new skills, keeping your brain busy with puzzles and knitting—or even brushing your teeth with your non-dominant hand—all help with neuroplasticity, your brain’s ability to do things in new and different ways.

Encouraging this process forces you to think about what you’re doing, growing and rewiring pathways to keep your brain healthy and strong.   

4. Prioritize sleep 

I’m sure you’ve experienced it before: You have a bad night, and the next day you feel like your brain’s foggy, making it harder to think and recall simple things.3

This is because sleep works like a nightly tune-up for your mind, allowing the neurons you’ve used while you were awake to rest, repair and prepare to work quickly and clearly the next day.

Snooze time is also the prime time for your brain to cement important memories—and get rid of the not-so-important ones—to make space for new memories the next day.

For most adults, about 7 hours of good-quality sleep does the trick. 

5. Consider a supplement 

When it comes to supporting our brains, we’ll take all the help we can get!

Some supplements appear to work alongside these other lifestyle changes to keep you sharp as you age. Gingko biloba and ginseng, both adaptogens, may help with mental clarity and mild age-related memory loss by improving blood circulation to your brain.

They also act as antioxidants to counteract damage from free radicals—substances that can cause harm to your body and brain in large amounts.*

The basics of CBD from a nutritionist 

From skin products to pet food to everything in between, CBD hemp oil is suddenly everywhere. But along with all the hype, there’s a healthy dose of skepticism—and a bit of controversy too. So if you’re not sure whether CBD is right for you, we get it. That’s why we’re here to help you unravel the basics.  

What exactly is CBD? 

CBD, or cannabidiol, is the second-most prevalent compound in the cannabis plant, just after THC (tetrahydrocannabinol). But unlike its more famous cousin, CBD has no psychoactive effect, meaning it doesn’t give you that feeling of euphoria1. It’s a different compound that interacts with different receptors in your brain.  

How does CBD work? 

Your body has something called an endocannabinoid system (ECS for short) that uses chemical signals to control a whole list of vital functions like immunity, pain, inflammation, hunger, the processing of emotions and those all-important zzz’s. It works day and night to keep these processes in balance. 

To get a bit more sciencey: Within your ECS, there are two major types of receptors: CB1 and CB2. Your CB1 receptors are found mostly in your central nervous system—your brain and spinal cord—whereas CB2 receptors are found in your peripheral nervous system, which includes all the nerves that branch out from your spine to carry messages to the rest of your body 2.  

So why does this sciencey stuff matter? Well, CBD mimics a cannabinoid-like substance called anandamide that your body makes to help manage mood, stress, inflammation, sleep and other processes.3 CBD’s unique chemical structure activates CB2 receptors in your peripheral nervous system, but not the CB1 receptors in your brain, which is why it doesn’t have a psychoactive effect. THC, on the other hand, activates both receptor types, leading to marijuana’s trademark high.4   

What are CBD’s health benefits? 

Although the current hype around CBD is new, its use actually dates back to ancient times, when it was used for pain, nausea and even epilepsy.1 Nowadays, CBD is touted mostly for its ability to help you feel calm, relaxed and less stressed. When times get tough, CBD sends signals to your ECS receptors that help keep your cortisol stress hormone under control. It also appears to promote a healthy inflammatory response and a better rest at night.1,5  

Studies of these potential benefits appear promising, but because of the complicated legal history around cannabis, research on CBD is limited, meaning more is needed to validate them.  

How should you source CBD? 

Most CBD products are made in a similar way: Manufacturers extract the compound from low-THC hemp plants and dilute it with a carrier oil like hemp seed or coconut oil. But despite what CBD lovers may say, not all CBD products are made equal, and not all will have the same effect. Before you buy, do your research. Make sure you use a reputable source, and find a product that works for you.

6 best supplements for eye health, according to a nutritionist 

If you’re like me, you put your eyes through the wringer on a daily basis. You park them in front of screens, you expose them to UV light, you irritate them with contacts, you might even smoke or skip that salad a little too often. These bad habits may not seem like a big deal now, but over time they can take a toll on your eye health. And when you’re older, jeepers creepers will you ever miss those peepers.  

You can lend your eyes a helping hand by adopting healthier habits—curbing screen time, wearing sunglasses, caring for your contacts, feasting on fish and colorful veggies, seeing an eye doctor on the reg—but you can also help them out with a smart supplement regimen. Here are our top picks to help you focus on your eye health.  

1. Vitamin A 

When you think about nourishing your eyes, vitamin A is probably the first nutrient that comes to mind—and for good reasons! This vitamin superstar helps your retina make the pigments it needs to detect the full spectrum, allowing you to see in low light.1 It also plays an incredibly important role in keeping your cornea and other parts of your eye hydrated. Vitamin A is only found in animal products like meat, eggs and milk, but to the vegans out there, don’t stress! Your body can make vitamin A from certain plant-based carotenoids.3 And you can always take a supplement. 

2. Carotenoids 

Wait, caro-what? Good question. Carotenoids are a group of antioxidants—including beta-carotene, lutein and zeaxanthin—that give dark leafy greens and red, orange and yellow fruits and veggies their color. These compounds support your eyes by fending off free radicals, natural substances that can damage cells when they start to build up. This is especially important if you spend long hours in front of a screen, since all that blue light can stress your eyes, causing those nasty free radicals to accumulate.2 What’s more, lutein and zeaxanthin are actually found in your retina, where they help block out blue light to keep your eyes healthy. So next time you make a salad, toss in a few colorful eye-friendly veggies like carrots, bell peppers, kale or spinach!  

3. Zinc 

Zinc is a trace mineral that has gained celebrity status in recent years for its immunity benefits. What might be surprising, though, is that it plays a major role in your eye health as well. Your eyes actually contain high levels of zinc, mostly in and around your retina, where it helps to reduce age-related damage. Zinc also plays a vital role in transporting vitamin A from your liver to your retina to make melanin, a pigment that lessens the effects of blue light.4 If you’re looking to add more zinc into your diet, you can find it in chicken, beans, nuts and whole grains. 

4. Omega-3s  

Omega-3s are essential fatty acids that are most often linked to heart health. What’s less well known is that they also support the blood vessels in your eyes—and may have a direct impact on the tiny meibomian glands on the edge of your eyelid that make your eye’s moisture-trapping oil film.5  Since your body can’t produce omega-3s, you need to get them from your diet. Two weekly servings of cold water fatty fish like salmon or mackerel should cover you. Or, if you’re not a seafood fan, you can take a supplement. 

5. Vitamin C 

Vitamin C is incredibly important to your sight. It’s a powerful antioxidant that helps counteract damaging free radical activity in your eyes. It’s also key to building the protein collagen, a major component of the sclera and cornea that make up the outer layer of your eyeball. You can get high amounts of vitamin C from bell peppers, strawberries and citrus. 

6. Vitamin E 

Vitamin E is a fat-soluble vitamin with powerful antioxidant properties that’s believed to prevent damage from free radicals and the breakdown of fatty acids in your retina. Rich sources of vitamin E include almonds, sunflower seeds, peanut butter, spinach and beets.

6 surprising health benefits of mushrooms  

There are lots of reasons to love mushrooms. They’re great sautéed in stir fry, cooked in risotto, stuffed with cheese or scattered on your favorite pizza. But these little fun guys offer benefits well beyond flavor. Many of the scrumptious species out there may also help your health. Here are just a few of the ways.  

1. Mushrooms are rich in vitamin D 

You’ve likely heard it before: Spend 10-30 minutes a day in the sun to get your dose of vitamin D, an important nutrient that plays a vital role in your bone health, immunity, cell growth, mood and more. What you might not know is that mushrooms work the same way!  

When they’re out catching rays, they also produce vitamin D. This is because they contain ergosterol, a natural compound that converts to vitamin D21 when exposed to UV-B. Amazingly, this even works after they’ve been picked; you can actually increase the vitamin D in your store-bought mushrooms by simply drying them in the sun—an effect that can last for more than a year!  

Thanks to this mechanism, mushrooms are one of the richest non-animal sources of vitamin D you can get. A half-cup of raw mushrooms—without added sunlight—will bring about 46% of your recommended daily intake to the table. 

2. Mushrooms are packed with powerful antioxidants 

When you think about high-antioxidant foods, you probably imagine colorful fruits and vegetables—not white and brown fungi. But mushrooms are actually packed with antioxidants. The two they have the most of—ergothioneine and glutathione—do a great job offsetting damage caused by free radicals, natural substances that can harm your body when they start to build up in your cells.2 Varieties like porcini, shiitake, oyster or maitake have the highest amounts of these helpful compounds, but really you’ll benefit from any mushroom you add to your meals.3 

3. Mushrooms may help your immune system 

Along with their high antioxidant properties, mushrooms are rich in micronutrients like selenium, zinc and vitamin B6, natural compounds that play a vital role in strengthening your immunity. Some species–including lion’s mane, shiitake, reishi and cordyceps—come with an added bonus: They contain a special fiber called beta-glucans that helps your body fight harmful bacteria and viruses.4 

4. Mushrooms help your gut 

Your body is inhabited by trillions of bacteria known as your microbiota, most of which camp out in your gut starting at birth. Your good microbiota—called probiotics—do all kinds of beneficial things. They help you stay regular, break down food, make vitamins, keep your immune system healthy and even impact your mood. As you age, the choices you make around your diet, medications, environment and lifestyle can alter your microbiota—sometimes in harmful ways. One way to counter these effects is with prebiotics, nutrients that feed your probiotics, the good guys in your gut. Mushrooms are a great source of prebiotics so pile them on your pizza to keep your gut in good order! 

5. Mushrooms may support heart health 

Another reason to celebrate mushrooms: they promote a healthy heart! Mushrooms are low in calories, cholesterol-free and contain almost no fat. They’re also low in sodium but high in potassium, which helps with normal blood pressure and heart health. So next time you’re cooking a stir fry or mushroom risotto, add an extra handful or two of these fungi. You’re doing both your heart and your palate a favor! 

6. Mushrooms may help your brain 

Find you forget where you put your car keys these days? As you age, your brain ages too, so processing information and multitasking can be more of a challenge. Mushrooms may just be able to lend a hand. This is because they’re rich in B vitamins that help your body produce neurotransmitters, chemicals that carry messages between your brain and body. For this reason, eating mushrooms at least twice a week can have a positive effect on your brain and nerve health.6 They’re not just good for your body; they’re also good for your mind.

5 best nutrients for building muscle  

Putting in long hours at the gym and still not seeing those gains in the mirror? Your diet could be to blame. When it comes to getting in shape, eating the right foods can be as important as the workout itself. There are several key nutrients that are essential for building muscle, and we’ve put together a list of the 5 most important. Hint: body builders need to eat broccoli too!    

1) Protein 

It’s no secret that your body needs protein to make muscle. But some sources may be more beneficial than others. Remember, proteins are made up of chains of amino acids (your 8th grade science teacher is beaming right now) and the exact combination depends on the source: The protein in whey contains different amino acids from the protein in spinach, say. To build muscle, you need sources that have essential amino acids—the ones your body can’t make on its own. Bottom line when it comes to muscling up—choose complete proteins that have all essential amino acids. Eggs, fish, soy, and lean meats are all great options.  

2) Omega-3 

Healthy fats like omega-3 probably aren’t the first thing that come to mind when you imagine a body builders’ diet. But they play an important role in muscle repair—which is key for muscle growth. Omega-3’s help keep your muscle cells healthy by balancing inflammation, and since exercise increases short-term inflammation, getting those omega-3’s can be beneficial for those gains. When you’re not busy pumping iron, try adding eggs, fish, chia seeds, olive oil or avocados to your diet.  

3) Vitamin D 

If supplements could wear capes, vitamin D would definitely be donning one. This superhero nutrient acts like a hormone. Among other functions, it tells your body to make muscle fibers. Not surprisingly, low levels of vitamin D may impact your muscle growth and lead to poor athletic performance—and as many as 42% of people aren’t getting enough. To keep your vitamin D in the healthy range, aim to get out in the sun at least 15 minutes a day or add a vitamin D supplement to your routine. 

4) Vitamin C  

Like vitamin D, vitamin C is needed to make muscle fibers—specifically collagen, the protein that keeps your joints flexible. Low levels are associated with lower muscle mass in adults, so if you’re blowing off your daily veggies, you may want to reconsider. Bell peppers, carrots, broccoli, spinach and potatoes are all great sources of vitamin C.  

5) Magnesium 

Another shameless plug fruits and vegetables? Don’t mind if we do! Magnesium is essentially a fitness guru, helping your cells to take up oxygen and keeping your heart and biceps pumping. It’s also one of the electrolytes that we lose through sweating. So if you’re a heavy sweater, make an extra effort to get enough magnesium in your diet. While we still don’t know if supplementing with extra magnesium helps increase your fitness, we do know that getting enough is key to a good workout. Pile your plate with avocado, black beans, spinach, pumpkin seeds and almonds.
