Vitamin D is one of the most powerful nutrients for supporting the immune system @ClevelandClinic 🌞

Who doesn’t want a healthy immune system? (Raise your hand. No one?) But did you know the role your diet plays in keeping it in top shape to protect you from toxins and infections?
Sadly, too many of us don’t eat enough of the fresh fruits, vegetables and other foods we need to keep ourselves healthy year-round. Healthy foods provide many substances including vitamins and minerals to keep us strong and healthy. You can’t just eat an orange or grapefruit or pop a vitamin pill and expect one quick burst of vitamin C to prevent a cold and to boost your immune system.
“A truly healthy immune system depends on a balanced healthy diet over time,” says registered dietitian Maxine Smith. “It’s like training for a battle and preparing your body ahead of time so it can through a good punch when attacked by viruses, bacteria and toxins. Other lifestyle practices such as regular exercise and good sleep will better prepare you for the battle.”
With some exceptions, it’s best to get your vitamins and minerals from your food rather than in pill form. Smith shares some tips for some of the top vitamins and minerals your immune system needs to perform:

1. Vitamin C
Vitamin C may help prevent infections or shorten their stay. Citrus fruits are a standout, but did you know there are other good sources? It’s true! Smith recommends the following:
Spinach.
Kale.
Bell peppers.
Brussels sprouts.
Strawberries.
Papaya.
Fun fact: vitamin C is in so many foods that most people may not need to take supplements unless a doctor advises it. Consult with your doctor before taking any vitamin C supplements

2. Vitamin E
Like vitamin C, vitamin E can be a powerful antioxidant that helps your body fight off infection. This important vitamin — part of nearly 200 biochemical reactions in your body — is critical in how your immune system functions. To get your vitamin E, think high-fat plant foods such as:
Almonds.
Peanuts/peanut butter.
Sunflower seeds.
Oils such as sunflower, safflower, and soybean oil.
Hazelnuts.

3. Vitamin A#

Vitamin A is an infection-fighter and comes in two forms: preformed such as in animal foods such as fish, meat and dairy or from plant carotenoids. Tuna is a great source of preformed vitamin A. When it comes to carotenoids, go colorful:
Carrots.
Sweet potatoes.
Pumpkin.
Butternut squash.
Cantaloupe.
Dark green leafy vegetables.

4. Vitamin D
Known as the sunshine vitamin, it’s one of the most important and powerful nutrients for supporting the immune system. Food sources are limited but include:
Salmon.
Mackerel.
Tuna.
Sardines.
Vitamin D fortified like milk, orange juice and cereals.
In general, it’s best to get most of your vitamins from food, but vitamin D may be the exception to that rule. Talk with your doctor to find out if you need a supplement.

5. Folate/folic acid
Folate is the natural form and folic acid is the synthetic form, often added to foods because of its health benefits. To get more folate, add more beans and lentils to your plate on a regular basis, as well as leafy green vegetables. Avocado is another tasty source. You can also get folic acid in fortified foods (check the label first).
Enriched pasta.
Enriched bread.
Enriched rice.

6. Iron
Iron, which helps your body carry oxygen to cells, plays a part in many of the immune system processes. It comes in different forms. Your body can more easily absorb heme iron (aka iron from animal products), which is abundant in:
Red meat (limit to smaller amounts and less often).
Chicken.
Turkey.
Canned sardines.
Oysters.
Clams.
Mussels.
Canned light tuna.
If you’re a vegetarian, have no fear. You can still find iron in:
Beans.
Broccoli.
Kale.
Iron-fortified cereals.

7. Selenium
Selenium seems to have a powerful effect on the immune system being important for preventing infections. Animal foods are the best sources, with the exception of Brazil nuts, that offer a whopping greater than 100% daily value in one nut. However, too much can be a problem, so keep to no more than one to two of these in a day. Look for selenium in:
Seafood (tuna, halibut, sardines).
Meat and liver.
Poultry.
Cottage cheese.

8. Zinc
Zinc is needed for the production of new immune system cells. It’s found primarily in animal foods but can be also found in some vegetarian food like.
Oysters.
Crab.
Lean meats and poultry.
Baked beans.
Yogurt.
Chickpeas.
Choose frozen when you can’t get fresh
Depending on where you live and what time of year it is, you can’t always get your hands on high-quality fresh produce. Keep in mind that buying frozen is a good option and can be quite convenient in our time-crunched world. Frozen food can still boost your immune system.
“Manufacturers freeze frozen fruits and veggies at ‘peak’ ripeness, which means they’ll pack a similar nutritional value as their fresh counterparts,” she says. “Just choose plain frozen foods rather than those with added sugars or sodium.”

Colorful fruits and vegetables are packed with phytonutrients that help calm inflammation — a natural process that, when chronic, can contribute to heart disease, arthritis and diabetes. by Tamara Soerense @MayoClinic

Can eating the rainbow help to reduce inflammation?

11/6/2025 by Tamara Soerense

Inflammation is a natural process initiated by the immune system in response to illness, trauma, toxins, physical stress and chronic disease. While acute inflammation is protective and allows our bodies to heal, it can become harmful if it persists, leading to chronic inflammation. Chronic inflammation, in turn, can lead to conditions such as arthritis, heart disease, and diabetes.

Several foods can contribute to inflammation. These include highly processed foods, refined carbohydrates, or foods high in added sugars. Conversely, other foods can help calm the immune system, decreasing inflammation.

Let’s explore which foods help lower inflammation and how they can be incorporated into an anti-inflammatory diet.

Fruits and Vegetables: Colorful fruits and vegetables naturally contain various phytonutrients and bioactive compounds that help keep inflammation in check. These foods form the foundation of the anti-inflammatory diet and can be enjoyed in abundance. For an extra boost of protection, try drizzling antioxidant-rich olive oil on your veggies..
Protein: Choose primarily from plant-based sources such as legumes, soy, nuts, and seeds, with smaller amounts from lean cuts of animal protein and fatty fish. The fats in these proteins, mainly monounsaturated and omega-3, play a significant role in combating inflammation. The American Heart Association recommends 6 to 8 ounces of fatty fish and 5 ounces of legumes, nuts, and seeds per week.
Whole grains: Whole grains contain all parts of the grain, whereas refined grains remove the germ and bran, eliminating important inflammation-reducing compounds. Of these, fiber is a bit of a superstar, shown to help reduce blood sugar and cholesterol levels. Aim for at least 50% of your grains from whole grain sources, such as rolled oats and brown rice.
Herbs and Spices: Herbs and spices add flavor to your food and help reduce oxidative stress, which can trigger inflammation. Add ginger, turmeric, clove, cinnamon, oregano, and garlic to your next meal.

What change can you make today to shift your body into a less inflamed state?

Consider adding one colorful fruit or vegetable to your diet each day. Suggestions include tomatoes, oranges, yellow bell peppers, arugula, blueberries, pumpkin and broccoli.

“Eat your broccoli,” may be a familiar refrain from your childhood. Maybe you didn’t love broccoli as a kid, but your parents were onto something. The “little trees” are full of fiber, folate, vitamins and more. Beth Czerwony, RD, LD. @ClevelandClinic

“Eat your broccoli,” may be a familiar refrain from your childhood. Maybe you didn’t love broccoli as a kid, but your parents were onto something. The “little trees” are full of fiber, folate, vitamins and more.

Broccoli is a member of the Brassica genus of plants, also known as the cabbage family. Broccoli’s relatives include Brussels sprouts, cabbage, cauliflower, chard and watercress. Many Brassicas have strong flavors and mix well with meats and other vegetables.

“A pile of steamed broccoli doesn’t appeal to everyone,” recognizes registered dietitian Beth Czerwony, RD, LD. “But broccoli is incredibly versatile and can be used in so many different dishes. Toss it in with your stir fry, chop it fresh in a salad or roast it with your baby potatoes. And with an abundance of nutrients, there are many benefits of eating broccoli.”

Broccoli nutrition facts

A cup of chopped raw broccoli has approximately:

31 calories.
6 grams of carbohydrates.
0 grams of cholesterol.
0.3 grams of fat.
2 grams of fiber.
2.6 grams of protein.
30 milligrams of sodium.
1.6 grams of sugar.

In addition, a cup of raw broccoli offers:

81 milligrams of vitamin C (90% daily value or DV).
93 micrograms of vitamin K (78% DV).
57 milligrams of folate (11% DV).
288 milligrams of potassium (6% DV).
19 milligrams of magnesium (5% DV).

Broccoli benefits

It’s worth finding ways to add broccoli to your diet because it’s a health-boosting dynamo. Here’s some motivation for you to get your green on: Some of the beneficial substances in broccoli are somewhat unique to the Brassica family of vegetables. Broccoli provides nutrients that may:

Reduce your risk of cancer.
Help control blood sugar.
Protect your gut.
Boost immunity.

As a superfood status, broccoli can improve your health with these five components:

1. Compounds to reduce cancer risk

“Broccoli offers some powerful molecules that protect your cells from damage,” says Czerwony. “Some of them even destroy cancer cells.”

Cancer-fighting molecules in broccoli include DIM, indole-3-carbinol and sulforaphane. According to studies, they may help:

Detoxify certain substances that promote the growth of cancer cells, which means they don’t remove the substances, but they remove the harmful effects.
Provide antioxidants, which prevent cell damage that can lead to cancer.
Stop the growth and spread of cancer cells.
Support apoptosis, your body’s process for destroying cells that could turn into cancer.

These anticancer molecules are in several of broccoli’s cruciferous veggie relatives, too. These nutrients don’t survive cooking or freezing. So, to get the benefits, raw broccoli is best.

“Some of these compounds are even more concentrated in broccoli sprouts,” notes Czerwony. “You can find broccoli sprouts in health food stores and many grocery stores. Sprouts are also easy to grow at home using a sprouting kit.”

2. Nutrients to help manage blood sugar

Both human and lab studies suggest compounds in broccoli may help lower blood sugar in people with Type 2 diabetes. This effect may be due to the antioxidants in broccoli, like vitamin C.

Research shows that fiber can also help with blood sugar management. At 2.5 grams of fiber per cup, broccoli is a good source of this nutrient.

3. Ligands to protect your gut

In a nonhuman study, researchers found that broccoli can help protect the lining of your small intestine. Compounds found in broccoli, called aryl hydrocarbon receptor ligands, help keep small intestine cells working well.

Why do those cells matter so much? When your small intestine lining is healthy, it only allows water and nutrients to pass through it into your bloodstream.

But when the cells of the lining are damaged, undigested food particles, bacteria and other disease-causing particles may pass through. A damaged small intestine lining can lead to infections and inflammation. It can also prevent you from absorbing the nutrients you need.

4. Vitamin C to boost immunity

Vitamin C is well-studied as an immune-boosting nutrient. When you don’t have enough vitamin C, you’re more likely to get infections.

The antioxidant effects of vitamin C also help your body keep free radicals under control. “Free radical damage is linked to all kinds of problems, including Alzheimer’s disease, autoimmune diseases, cancer, heart disease and Parkinson’s disease,” says Czerwony. When you don’t have enough antioxidants to neutralize free radicals, they damage your cells.

Surprising but true: Broccoli has more vitamin C than oranges. In 1 cup of the green cruciferous veggie, you get a whopping 81 milligrams of vitamin C. That’s 90% of the daily U.S. recommended dietary allowance (RDA) for adults. (An orange has about 70 milligrams.)

5. Nutrients to help heart health

Research suggests certain bioactive compounds in broccoli may boost your heart health in a variety of ways. It may:

Lower triglycerides and LDL (“bad”) cholesterol: “High LDL can lead to fatty deposits on your artery walls, increasing your risk of artery disease, stroke and heart attack,” Czerwony explains. Research shows that eating broccoli can lower triglycerides, a type of fat, as well as LDL.
Provide fiber: According to a review of 22 clinical trials, fiber can reduce your risk of cardiovascular and coronary artery disease.
Reduce calcium buildup in blood vessels: When calcium builds up on your blood vessel walls, it increases your risk of heart attack and stroke. According to research, broccoli can help reduce this calcium buildup.

Is frozen broccoli healthy?

“If you want those anticancer compounds like sulforaphane, choose fresh broccoli,” advises Czerwony. Freezing inactivates sulforaphane.

“Frozen broccoli also loses a bit of its vitamin content. But overall, frozen broccoli is still very healthy. It’s better than not eating any broccoli because you still get a lot of the health benefits,” she continues.

These crispy sweet potato wedges come out Cajun spicy and sweet. They’re also really healthy. They’re loaded with antioxidants and phytonutrients and are a great source of beta-carotene.

Recipe: Baked Cajun Sweet Potato Fries

Swap regular fries for these delicious, and nutritious, potato wedges

These crispy sweet potato wedges come out Cajun spicy and sweet. Don’t tell anyone but they’re also really healthy. They’re loaded with antioxidants and phytonutrients and are a great source of beta-carotene. Another plus? As complex carbs, they digest slowly and raise blood sugars gradually — keeping you from a spike and drop-off.

Ingredients

2 sweet potatoes, cut into wedges (about 8 wedges per potato)
1 tablespoon olive oil
2 tablespoons Cajun seasoning

Directions

Preheat oven to 425 F.
In a large mixing bowl, combine the sweet potatoes, oil and Cajun seasoning. Mix well to evenly coat wedges.
Spread the wedges in a single layer on one (or two, if needed) ungreased baking sheets.
Bake for 30 minutes or until crispy and brown on one side.
Flip fries over and bake for another 30 minutes or until the wedges are crispy on the outside and tender inside.

Ingredient health benefits

Sweet potatoes: These root veggies are beloved the world over for their flavor and versatility. But did you know there’s more to sweet potatoes than … well, just being sweet? They’re also packed with essential vitamins and minerals like vitamin B6, vitamin C, vitamin A and potassium. These nutrients help support many aspects of your overall health, including your immune system, metabolism, blood pressure and vision. Sweet potatoes also have carbohydrates and fiber to fuel your cells and promote healthy digestion.
Olive oil: This cooking oil is one of those ingredients that’s actually worth the hype. Olive oil is full of unsaturated fats and polyphenols. These compounds support your heart and fight inflammation that can harm your cells. Vitamin E and vitamin K, also known as fat-soluble vitamins, maintain radiant skin and strong bones. Olive oil also elevates your good “HDL” cholesterol while lowering your “bad” (LDL) cholesterol. And powerful antioxidants suppress free radicals, damaging little particles that harm your cells in ways that can lead to cancer. While all olive oil has these benefits, extra virgin olive oil (EVOO) is the highest quality, so don’t hesitate to pick some up if it fits within your budget!

2026 Is the Year of the Cabbage: Meet the Most Underrated Leafy Green

By Audrey Noble

January 13, 2026

Cabbage often—and unfairly—gets overlooked, with flashier veggies and protein-dense superfoods getting all the attention. But as far as nutritional food options go, the leafy green is pretty hard to beat. A staple in different cuisines (American coleslaw! Middle Eastern malfouf! Chinese suan la bai cai!), cabbage has been a longtime favorite amongst global chefs.

“Much of this stems from its versatility,” Woldy Reyes, chef and author of the cookbook In the Kusina: My Seasonal Filipino Cooking, tells Vogue. “We are seeing a growing trend of chefs utilizing it as a centerpiece, such as cabbage steaks, rather than as a side dish. The culinary appeal has never been stronger.”

“Its popularity stems from its ability to transform,” adds Tatiana Mora, chef of plant-based Michelin star restaurant Mita. “It can be eaten raw, fermented, steamed, roasted, or sautéed, consistently providing flavor, texture, and nutrition. I love it because it is a noble vegetable that grows easily, keeps well, and can be used almost entirely, making it perfect for a conscious and respectful approach to cooking.”

It’s accessible, easy to cook, and delicious. Here are all the reasons cabbage deserves a seat at your table (get it?) in 2026.

What is cabbage?

Cabbage is a leafy green that is part of the brassica plant family (which also includes broccoli, cauliflower, brussels sprouts, and kale), says Amy Shapiro, RD, registered dietitian and founder of Real Nutrition. It comes in several varieties, but the most common ones you’ll see are green, red (or purple), and savoy. What makes cabbage different from other leafy greens is its density and durability. “It’s heartier, stores longer, and holds up well to cooking, fermenting, and shredding,” Shapiro says. “Nutritionally, it shares many benefits with other cruciferous vegetables, but it’s often milder in flavor and more versatile across cuisines.”

The Benefits

Besides its versatility, one of the main benefits of cabbage is its many nutrients. Shapiro lists other main benefits of the leafy green:

Supports Gut Health

Shapiro says that, because cabbage contains fiber and other compounds that support digestion, eating this leafy green can benefit the gut bacteria and boost gut health.

Anti-Inflammatory Properties

Cabbage is also rich in antioxidants and phytonutrients that studies have shown can reduce inflammation, she says.

Boosts Heart Health

Along with fiber, cabbage has potassium, which supports healthy cholesterol levels and blood pressure. Cabbage also has vitamin K, which is essential for blood clotting (and bone health). Shapiro points to red cabbage in particular, which she says contains antioxidants called anthocyanins that studies have shown can improve brain and heart health.

Regulates Blood Sugar

Cabbage is low in calories and carbs while being high in fiber, which can help stabilize glucose levels in the body.

Boosts Immune System

Shapiro says that cabbage is rich in sulfur-containing compounds to help strengthen your immune system’s defences—and vitamin C, which studies have shown can provide antioxidant protection and support immune health.

Muscles in your body are a use-or-lose proposition. You need to use them to keep them strong!@ClevelandClinic – Susan Williams, MD. endocrinologist

Cleveland Clinic

@ClevelandClinic

Muscles in your body are a use-or-lose proposition. You need to use them to keep them strong!

You may not realize it, but we all start losing 1 percent of muscle mass each year after age 30. That’s why your diet in later years should not look the same as it did when you were younger, says endocrinologist Susan Williams, MD.

Skipping breakfast, eating fast food and being inactive in your 20s and early 30s might not hurt your health in the short term. However, poor nutrition and lifestyle habits take their toll over time.

People who embrace good habits early on really get ahead of the game, Dr. Williams says. But it’s never too late to start eating better and taking better care of your body.

Whether you’re 30 or 50, Dr. Williams offers three important tips to get started in eating right when you are thinking about your long-term health.

1. Keep your weight in check

A roller coaster of weight gain and loss can change your body composition and leave you with more fat mass and less lean muscle mass.

2. Eat three balanced meals a day

You also want to limit your snacks in between. The word “balanced” is especially important because eating a wide variety of foods will help you prevent nutritional deficiencies.

Dr. Williams suggests this simple shopping list:

Lean proteins. Choose chicken, white fish, oily fish like salmon, eggs, tuna fish and red meat (less frequently than other protein).
Whole grains. This includes multigrain breads, and long-cooking rice or oats.
Veggies. Go for fresh or fresh frozen. Choose what’s in season and enjoy a variety to get the vitamins and minerals your body needs.
Fruit. Fresh fruit is best, followed by frozen. Canned fruit can be OK, but choose options in light syrup or water. Check the label and avoid added sugar.
Dairy. Choose milk, yogurts, cheeses and cottage cheese that are low-fat or fat-free.

Steer clear of cookies, cakes, pies, ice creams, juices and rich desserts. If that sounds like no fun, Dr. Williams advises treating these foods as treats. Save them for dining out or special occasions, but don’t make them part of your daily diet.

3. Use your muscles

Eating protein and being physically active are equal partners in the quest for maximum health, Dr. Williams says. Muscles are made of protein, but simply eating protein is not enough to save them.

“Muscles in your body are a use-or-lose proposition,” she says. “You need to use them to keep them strong.”

Can’t carve out time for the gym? Try this daily routine:

In the morning, stretch for 10 minutes.
At lunch, eat and then walk for 10 minutes.
After dinner, spend 10 minutes with stretch bands or light weights.

Even a half hour of physical activity can make a world of difference, especially if you make it a habit in your 30s. “Don’t let your weight creep up while your muscle mass creeps down over your 30s and 40s,” Dr. Williams says. The longer you wait, the harder it will be to get started — and the more muscle you will have already lost.
