You know exercise builds muscles, strengthens bones, keeps your heart healthy and your mind sharp. But it also does something that you might not think much about: It helps keep your immune system â your internal defenses against infection â in tip-top shape.
If you take time for some physical exertion each day, it helps get your body ready to attack bacteria, viruses and toxins that can sneak in and make you sick.
But how much exercise is effective? Do too little or too much, and it wonât have the best effect on your immune system.
Clinical immunologist  Leonard Calabrese, DO, answers common questions about how exercise can impact your immunity and how to use your workouts to shut out a world of would-be invaders.
Q: How does breaking a sweat boost immunity?
A:Â If you exercise moderately on a regular basis, it tunes up the immune system in many ways. It enhances your broad-based defenses against viral infections, such as those causing upper respiratory infections.
Working out regularly also reduces the risk of many chronic diseases such as cardiovascular, respiratory illnesses and metabolic diseases, such as type 2 diabetes.
Q: How much exercise do you need?
A:Â Fortunately, you donât have to push yourself to the limit to rev up your immune system. In fact, your immune system needs less of a workout than you get with your average cardio routine.
Focus on getting 20-30 minutes of moderate exercise, five days a week, and your immune system will thank you.
Q: What types of exercise are most helpful?
A:Â Moderate exercises, including biking or walking briskly in your neighborhood, are good ways to get your blood flowing. Swimming is also a good option for non-weight-bearing exercise for your joints.
Also try mind-body exercises such as Tai-Chi, Qi Gong and yoga, which are all options that help keep your joints flexible. These exercises also reduce chronic stress, which in itself is a powerful immune booster. These exercises can also help alleviate osteoarthritis and fibromyalgia symptoms.
Q: Can too much exercise set your immune system back?
A:Â Yes, though, the level to which it can slow your system down is still up for debate.
Research shows that exercising for more than 1.5 hours without refueling your body or giving it enough time to recover suppresses your immune responses for up to a few days. During that time, your cortisol levels rise, your white blood cell count drops and youâre more likely to develop a respiratory infection.
This problem usually affects elite athletes, such as marathon runners, most.
On the flip side, staying sedentary also increases your risk of infection, inflammation and chronic disease.
Q: Can exercise make an illness worse?
A:Â Yes, it can. This is a complex issue, but I like to tell my patients to do a âneck check.â If your symptoms are mostly of a mild cold without fever or lower respiratory symptoms, such as a productive cough, wheezing or shortness of breath, mild exercise can actually reduce congestion and may make you feel better.
If your symptoms are primarily in your lungs or you have a significant fever its better to rest until things settle down. Regardless, good hydration is important.
Spending time in nature has always been a source of comfort and strength. Gardens and green spaces provide not only beauty and joy, but also vital support for our mental, physical and spiritual wellbeing.

This dairy product can help you lose weight, manage blood sugar and strengthen bones
Cottage cheese doesnât typically receive a lot of attention. It gets left out from the fancy cheese counter at the grocery store. It doesnât make the cut for a charcuterie (meat and cheese) board. And it isnât typically included in recipes for favorite foods such as pizza, grilled cheese or baked ziti.
Itâs a soft, white, fresh cheese thatâs different in texture and taste than more popular cheddar, Parmesan and blue cheeses. But cottage cheese holds a prominent place in the dairy aisle for good reasons, says registered dietitian Julia Zumpano, RD, LD.
âItâs a portable food thatâs easy to add to your diet,â she says. âAnd cottage cheese offers lots of health benefits.â
As a dairy product, cottage cheese is a great calcium source, which is important for bone health. Having healthier bones makes you less likely to get osteoporosis (weak bones). Cottage cheese in your diet can even help with your blood sugar levels.
Thinking about giving cottage cheese a go? Zumpano explains what you need to know.
Is cottage cheese healthy?
Cottage cheese is low in calories while providing protein and vital nutrients, Zumpano says, making it one of the healthiest cheeses you can eat. Itâs made by curdling pasteurized (sterilized) cowâs milk â when milk turns acidic, the milk protein separates and forms curds (clumps). These loose curds serve as the base for cottage cheese.
Depending on the fat content of curdled dairy milk, cottage cheese is available as nonfat, low fat (1% or 2%) or whole fat. The milk type affects the nutritional content.
âTo get the most bang for your buck, choose a low-fat or even full-fat cottage cheese,â Zumpano advises. âNonfat cottage cheese may sound like a good idea, but it contains less protein and wonât be as satisfying.â Full-fat cottage has 1.5 grams more of saturated fat when compared to 2% but can be the most satisfying.
Health benefits of cottage cheese
Cottage cheese may be mild in flavor, but it packs a punch when it comes to potential health benefits. Some of the many benefits of cottage cheese include:
Provides good nutrition
A 100-gram serving (just under a half cup) of low-fat (2%) cottage cheese provides:
Three factors make cottage cheese a great choice if youâre looking to lose pounds or maintain your weight:
High in protein:Research finds that eating a high-protein diet helps curb your appetite and manage hormones associated with appetite, digestion and insulin release.
Low in fat: Full-fat cottage cheese contains less fat than some other cheeses (4% fat versus 30% fat in cheddar), and its high protein makes it an excellent low-fat option.
Provides calcium:Studies show that increasing calcium can help you lose weight when combined with a calorie-restricted diet.
Cottage cheese isnât the only dairy food to provide these advantages. Greek yogurt can also check these boxes. But if youâre deciding between the two, Zumpano recommends cottage cheese. âFull-fat cottage cheese and full-fat Greek yogurt have the same amount of fat, but cottage cheese has 25% more protein.â
Provides essential amino acids
Cottage cheese is rich in casein (pronounced âKAY-seenâ) protein. Itâs a complete protein that provides essential amino acids, which are all the building blocks of protein that your body needs.
Amino acids help your body work smoothly. They affect your:
Phosphorus is critical for proper bone development and strength, especially during growth spurts or when healing from a fracture.
Protein helps maintain bone mineral density and can reduce the risk of fractures.
âBone health is critical as you age,â Zumpano shares. âAdding cottage cheese to your diet is an easy way to strengthen them.â
Helps you control blood sugar levels
Plain cottage cheese is low in carbohydrates, making it a great option for anyone watching their blood sugar. The slow-digesting casein protein in cottage cheese also helps prevent blood sugar spikes.
âTo get this benefit of cottage cheese, choose plain cottage cheese,â Zumpano recommends. âAvoid cottage cheese pre-packaged with fruit and check the label for added sugar.â
Contributes to a balanced gut
Probiotics are live microorganisms that can improve the balance of good and bad bacteria in your gut (gut microbiota). The curdling process used to produce cottage cheese adds beneficial bacteria that can promote better gut health. But unlike Greek and regular yogurt, which almost always contain probiotics, not all cottage cheese is created equal.
âIf you want cottage cheese that provides probiotics,â Zumpano says, âcheck the label to see if it says it contains âlive and active cultures.ââ
Promotes muscle development
The slow-release protein in cottage cheese doesnât just help with digestion. Itâs also important for building muscle tissue and helping your muscles recover after a workout.
âCasein protein provides your cells with amino acids consistently over a longer period, which helps muscles recover instead of breaking down,â Zumpano explains. Consider having cottage cheese after a workout to get the maximum benefit for your muscles.
Reduces your risk of some cancers
Research shows that increasing dairy intake may lower your risk for some (though not all) cancers. âThereâs still a lot to learn about the connection between dairy and cancer prevention,â Zumpano states. âBut itâs clear there are protective benefits to including dairy in a balanced diet.â
Experts believe getting more calcium may offer protection from:
Bladder cancer.
Breast cancer.
Colorectal cancer.
Stomach (gastric) cancer.
Tips for adding cottage cheese to your diet
The United States Department of Agriculture (USDA) recommends that adults get three cups of dairy daily. Cottage cheese can help you reach that goal.
When you incorporate cottage cheese into your diet, remember to:
Check the nutrition label: Single-serve containers of cottage cheese may vary in size and nutritional content.
Consider your lactose tolerance: The lactose in cheese decreases with age. As a fresh, unripened cheese, cottage cheese often contains more lactose than aged cheeses. If you have lactose intolerance, consider a cottage cheese thatâs lactose-free.
Keep an eye on sodium: Cottage cheese can be high in sodium, so opt for low-sodium or sodium-free cottage cheese to protect yourself from high blood pressure and heart disease.
Get creative: There are many ways to eat more cottage cheese. Consider adding cottage cheese to your eggs or pancake mix. Bake it into muffins or cakes. Or use it as a substitute for sour cream or ricotta cheese.
The term âbreakfastâ means breaking the fast. And at some point in our day, all of us do that, whether itâs at 7 a.m. or noon. Ideally, the recommendation is to put some food in your belly within two hours of getting up for the day.

Strawberries are an iconic summer fruit â delicious in lemonade, on shortcakes or just straight out of the basket. And it turns out they may be the sweetest way to stay healthy, too. Registered dietitian Bailey Flora, MS, RDN, LD, explains the benefits of strawberries and what nutrients they contain that make strawberries so good for you.
Why are strawberries good for you?
âStrawberries give you a lot of nutritional value for very few calories,â says Flora. âTheyâre tasty but naturally low in sugar. Thatâs a combination thatâs hard to beat.â
For starters, strawberries are loaded with vitamin C. Eight medium strawberries contain 160% of your daily recommended amount â the amount that the U.S. Food and Drug Administration (FDA) recommends you eat every day. Thatâs more vitamin C than you get from an orange, the fruit famous for its vitamin C.
Strawberries are also packed with antioxidants, which protect cells from damage. The primary antioxidant in strawberries is anthocyanin, which gives the fruit its color. The amount of anthocyanin in strawberries increases as the fruit ripens. So, the redder the berry, the more antioxidants it contains.
Strawberries also have fiber and several other important vitamins and minerals, including manganese, potassium and folic acid. And strawberries have less natural sugar than other popular fruits such as apples and bananas.
Health benefits of strawberries
Strawberries are a nutrient-rich snack that can:
1. Boosts brain power
As your brain ages, it can lose some of its mental sharpness. But according to research, eating strawberries protects your brainâs processing powers as you get older.
The Nursesâ Health Study measured brain function in more than 16,000 participants over six years. It found that people who ate the most blueberries and strawberries had less cognitive decline â their thinking and processing abilities didnât weaken as much. They had the brain power of someone up to two and a half years younger.
Researchers believe the protective effects are due to the antioxidants that safeguard cells. Some of the antioxidants in strawberries also reduce systemic inflammation, when your body is in a state of constant inflammation (swelling and irritation). Systemic inflammation is a key factor in the development of Alzheimerâs disease.
2. Strengthens your immune system
Strawberries are a great source of vitamin C (ascorbic acid), which you need to get from food, as your body canât produce it. In rare cases, people who donât get enough of this crucial vitamin develop scurvy, a disease that causes bleeding, bruising and anemia.
Vitamin C plays an important role in wound healing. And it may prevent and treat respiratory and systemic infections too. Research shows that vitamin C increases the production of:
T-cells, which remove infected and cancerous cells.
B-cells, which create antibodies so your body can better defend against germs in the future.
Vitamin C is also anti-inflammatory, lowering your stress response triggered by illness or just your busy life. To ward off germs, researchers suggest getting 100 to 200 milligrams (mg) of vitamin C a day â and more when youâre sick. As eating eight medium strawberries gives you 160 mg, it takes just a handful of berries to help keep your immune system in good shape.
âThere isnât enough evidence to say whether vitamin C can prevent colds and the flu,â says Flora. âAnd it can be more beneficial to choose vitamin-C-rich foods like strawberries over vitamin C supplements, as you get additional health benefits. With strawberries, that includes fiber and other phytonutrients and vitamins that cannot be replicated in a vitamin supplement.â
3. Protects heart health
Flora says that popping a few strawberries in your mouth isnât just a way to stave off hunger â itâs also a heart-healthy food choice. Research shows that strawberries can help prevent several conditions that can lead to heart disease and stroke, as well as diabetes, which increases the likelihood of heart disease. Eating more strawberries can help you:
Lower cholesterol
In one small study, participants consumed two drinks a day, each made with 25 milligrams of freeze-dried strawberry powder blended with water. Thatâs about the same as eating 3.5 cups of fresh strawberries a day. After a month, the participantsâ total cholesterol was 5% lower.
The cholesterol-lowering results of that study were echoed in another study that gave participants the same amount of freeze-dried strawberry powder. But this time, they consumed the drink for two months. Researchers compared the results to a group that just drank more water. Those who sipped the strawberry drink saw their cholesterol decrease by 10%.
Decrease triglycerides
Triglycerides are fats found in your blood. Having high triglycerides increases your risk of heart disease. And when triglycerides break down, they leave byproducts that trigger inflammation, attracting sticky deposits to blood-vessel walls. That material can clog your arteries (atherosclerosis), explains Flora.
But eating a pound of strawberries a day may reduce triglycerides by 20%. Thatâs the result of one study, which also found that strawberries reduced total cholesterol by 8%.
4. Reduces inflammation
Widespread internal inflammation contributes to multiple diseases, including heart disease. Lifestyle factors like a poor diet, low physical activity and smoking can lead to inflammation.
Eating more strawberries is a step in the right direction to boost your heart health, says Flora. Thatâs because the most prevalent antioxidants in strawberries are anthocyanins, known for their anti-inflammatory effects.
5. Helps manage blood sugar
Too much glucose (sugar in your blood) is a risk factor for Type 2 diabetes, making you more likely to develop heart disease, too. If youâre watching your blood sugar levels, strawberries are a good way to satisfy your sweet tooth.
In a Finnish study, people who ate strawberries with a piece of white bread released 26% less insulin compared with eating bread with a cucumber. Participants also ate the bread with other berries, including raspberries and cranberries. Only strawberries weakened the post-meal blood sugar spike.
Strawberries are a great addition to a healthy diet, especially when you eat them on their own â Flora advises laying off the calorie-laden whipped cream, cake or ice cream. (Sorry!) Theyâre delicious, full of good-for-you nutrients and low in sugar. Try this strawberry smoothie. (Surprise â itâs green!) And for a strawberry treat thatâs not too sweet, make these strawberry pretzel squares at your next get-together.FACEBOOKTWITTER
Ironically, not every pear is âpear-shaped.â One variety, Asian pears, is actually shaped like an apple. But no matter their shape, all pears are rich in disease-fighting nutrients.
âPears are so healthy, and most people tolerate them very well,â says registered dietitian Beth Czerwony, RD, LD. âTheyâre terrific for your digestion and have other impressive health benefits. Theyâre a perfect snack if youâre craving something sweet.â
Types of pears
Pears are members of the Rosaceae plant family, along with apples, apricots, cherries, peaches and several other fruits and berries. Pears can range in texture, color, crispness, juiciness and sweetness. Common varieties you may find in the grocery store include:
Anjou (green or red).
Asian.
Bartlett.
Bosc.
Comice.
Concorde.
Forelle.
Seckel.
Starkrimson.
Health benefits of pears
Are pears good for you? Absolutely. Pears are a great source of antioxidants, fiber, potassium and vitamin C. But theyâre not just full of nutrients â they also may lower your risk of some diseases. Here are five ways pears boost your health.
1. A nutritious source of vitamins and minerals
Like most fruit, pears are a source of good nutrition. One medium pear has approximately:
Nobody enjoys the dreaded crash that happens after sugary foods spike your blood glucose. Steady blood sugar means a steady supply of energy, which is healthier for your body. Blood sugar management is even more important if you have diabetes.
Czerwony says pears may help stabilize blood sugar and even reduce your risk of Type 2 diabetes. How? Fiber, for starters. A medium pear offers nearly one-quarter of the fiber you need in a day. Fiber helps keep blood sugar steadier by slowing your bodyâs absorption of sugar.
Pears also contain anthocyanin, an antioxidant. An observational study suggests a link between eating anthocyanin-rich foods and a lower risk of Type 2 diabetes.
Another study showed that eating pears could significantly lower your odds of developing Type 2 diabetes. For each serving of pears eaten per week, researchers found a 3% lower risk of Type 2 diabetes.
In addition, pears are a low-glycemic food, which means they wonât spike your blood sugar like sugary foods and some fruits can.
3. Relieves constipation and improves digestive health
Fiber adds bulk to and softens your stool, which helps things move along in your gut. Lots of foods contain fiber, but pears are a particularly excellent source.
A single pear contains 6 grams of fiber (more than 20% of what an adult needs in a day). And pectin, a type of fiber in pears, has some specific benefits. Pectin is a soluble fiber known to help:
Constipation: In a study of 80 people with constipation, pectin significantly improved food movement through their digestive systems and reduced symptoms.
Gut microbiome: Pectin promotes the growth of good bacteria in your colon, according to a review of several studies, helping your microbiome stay healthy.
To reap the fibrous benefit of pears, donât skip the skin. âPear skin contains a significant amount of the fruitâs total fiber content,â notes Czerwony.
4. Lowers inflammation
Inflammation happens when your immune system tries to protect you from something â an infection, a toxin or some other offender. Some temporary inflammation is actually a healthy response to these things. But when inflammation hangs around, it can contribute to diseases such as Alzheimerâs, asthma, cancer and Type 2 diabetes.
Antioxidants are nutrients that can prevent some of the cell damage that leads to inflammation. Pears are rich in powerful types of antioxidants called flavonoids.
Research shows that flavonoids can reduce inflammation and lower the risk of:
Potassium, known to help reduce high blood pressure â another risk factor for heart disease.
In addition, a study examining the effects of fruit and vegetable consumption suggests eating pears lowers your risk of stroke. And one large clinical trial showed a link between eating pears and a lower risk of dying from heart disease.
Are fresh, canned or frozen pears better?
âIn general, fresh fruits are best because they have the highest amount of nutrients,â explains Czerwony. âFrozen is usually a close second to fresh. The heat of canning, though, can break down certain nutrients.â
But donât avoid canned pears completely. Theyâre still good for you. She advises looking for pears in water rather than syrup, which adds unneeded sugar.
âYou might be surprised by what you can do with fresh pears,â she adds. âThink of how you use apples â sliced raw, in pies or baked â and you can do all those things with pears.â
Fiber is a crucial part of a healthy diet that does much more than most people realize. It helps regulate blood sugar levels, supports heart health by lowering cholesterol, feeds the good bacteria in your gut to aid digestion and may even reduce the risk of chronic conditions⌠pic.twitter.com/bkCzE9FUUq
