6 Foods That Boost and Improve Your Immune System

Bring on the Broccoli

Broccoli to the Rescue

Broccoli is a nutrient-packed powerhouse to support your immune system. One cup of broccoli provides as much vitamin C as an orange. The veggie is also high in beta-carotene, potassium, magnesium, zinc, and iron. Broccoli supplies an array of B vitamins (B1, B2, B3, and B6). Together, these vitamins and minerals help the immune system to run in top form. Another healthy compound offered up by broccoli: glutathione, the master antioxidant in the body.

Harness the Power of Garlic Cloves

Bring on the Bulbs

People have praised garlic for ages for its immune boosting properties. Garlic has antibacterial, antiviral, and anti-fungal properties. The bulbs are rich in antioxidants that quench free radicals that play a role in Alzheimer’s disease, heart disease, cancers, and other conditions. The antiviral properties may be helpful in reducing the severity of colds, flu or COVID-19 infections. In one study, people who took garlic supplements during cold season caught fewer colds than those who took placebo pills. If you do catch a cold, garlic can shorten the duration of it. If you do try garlic supplements, be mindful that the one you choose contains the active ingredients contained in real garlic.

Garlic and Cancer

Garlic boosts the portion of the immune system that is tasked with fighting viruses and cancer. Several studies have documented a link between garlic use and reduced rates of many different types of cancers. People who regularly consume lots of raw or cooked garlic have 30% to 35% fewer colorectal cancers than those who do not eat the allum. In one small study of people who had inoperable pancreatic, colorectal, or liver cancers, immune function was improved when participants took aged garlic extract for 6 months.

Miso Soup to the Rescue

Fermented Foods and Immunity

Miso soup has been a staple in Japanese cuisine for centuries. Miso is a salty paste made from fermented soybeans. It is rich in probiotics that are beneficial for gastrointestinal health and boosting the immune system. A lack of beneficial bacteria or an imbalance of bacteria in the GI tract is associated with a variety of medical conditions including irritable bowel syndrome (IBS), food allergies, gastroenteritis, inflammatory bowel disease (ulcerative colitis and Crohn’s disease), and even certain kinds of cancers. Sipping a cup of miso soup is a great way to introduce beneficial food-based probiotics into the GI tract.

Busy Little Bugs

Beneficial microorganisms found in miso soup and other fermented foods perform a variety of necessary functions in the GI tract. They synthesize vitamins and amino acids. They produce short-chain fatty acids (SCFAs) that the cells lining the GI tract use for fuel. The probiotics establish a healthy balance of flora in the gastrointestinal tract, protecting against pathogenic strains that try to take hold. About 70% of the immune system lies in the gut. Healthy, balanced gut flora makes for a strong immune system.

Chicken Soup for the Cold

Serving Up a Bowl of Relief

Mom was right to make a pot of homemade chicken soup when you got sick. It turns out there are very real, scientific reasons chicken soup helps you get over a cold more quickly. When cold viruses invade tissues of the upper respiratory tract, the body responds by triggering inflammation. This inflammation signals white blood cells to move to the area and stimulates the production of mucus. Ingredients in chicken soup appear to halt the movement of white blood cells, thereby decreasing mucus associated with colds. Too sick to cook from scratch? Canned chicken soup can ease cold symptoms, too.

More Cold-Fighting Remedies

To get over a cold more quickly, sip lots of warm liquids like chicken soup, ginger tea, and warm water with lemon. Staying hydrated helps thin mucus secretions and flushes the virus out of your body. Taking zinc lozenges, syrup, or tablets within 24 hours of exhibiting cold symptoms can help reduce the duration of a cold. Taking vitamin C supplements throughout cold season may not keep you from catching a cold, but it may help ease symptoms if you do catch one. It may ease symptoms of the flu and coronavirus infections, too.

Reap the Rewards from Pomegranate Juice

Harness Purple Power

Beneficial compounds in pomegranate extract have been found in lab studies to inhibit the growth of harmful types of bacteria including E coli O157:H7, Salmonella, Yersinia, Shigella, Listeria, Clostridium, Staphylococcus aureus, and other organisms. There’s also evidence pomegranate compounds inhibit the growth of bacteria in the mouth that contribute to periodontal disease, plaque buildup, and gingivitis. Pomegranate extracts have antiviral properties against the flu, herpes, and other viruses. In addition to fighting bad viruses and bacteria, there is evidence that pomegranate extracts promote the growth of beneficial gut flora that boosts the immune system including Bifidobacterium and Lactobacillus.

5 Ways to Enjoy Pomegranate

Most people enjoy pomegranate by eating the jewel-colored seeds after cutting open the fruit. There are many other ways to indulge in pomegranate.

• Add tart, colorful pomegranate seeds to fruit salad.
• Cool down with pomegranate lemonade on hot summer days.
• Make a lovely salad with watercress, endive, blood oranges, and pomegranate seeds.
• Mix pomegranate seeds into wild rice pilaf.
• Use pomegranate seeds to make a tasty relish to top meats.

Make Friends with Ginger

Anti-inflammatory Root

Antioxidant compounds in ginger root have potent anti-inflammatory and immune-boosting properties. Normal metabolic processes in the body, infections, and toxins all contribute to the production of free radicals resulting in oxidative stress. Antioxidants in foods like ginger quench free radicals and help guard against arthritis, cancer, neurodegenerative disorders, and may other conditions. Grate some fresh ginger and steep it in hot water to make tea. Fresh grated ginger also makes a great addition to healthy stir fried veggies. Ginger has proven antibacterial and antiviral properties.

5 Ways to Eat Ginger

What can you do with ginger root? A lot! Here are a few ideas to add more ginger to your menu.

• Add ginger to hot chocolate for an unexpected kick.
• Grated ginger makes a lovely addition to carrot cake or spice muffins.
