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 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 sulforaphaneAccording 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 strokeAccording 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.
