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.
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.
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.
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

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.
