Whether in winter or summer, colds are still a common disease, few people know that the health of the digestive system, especially the intestines, plays an important role in the ability to fight this disease-causing virus.
According to nutritionist Pooja Makhija (India), about 70% of the body's immune cells are in the intestines, and if the intestinal microflora is not healthy, the absorption of essential vitamins such as zinc and vitamin D will be reduced, weakening immunity.
Makhija explains that the real cold is because the intestines cannot prevent the invasion of the virus. The gut microbiome is diverse and rich, but consuming too many antibiotics or prolonged stress can damage this microbiome, causing a condition called leakage syndrome, which negatively affects immune health.
To enhance gut microbiota, Makhija recommends prioritizing warm, easy-to-digest foods over raw materials. Ms. Makhija also suggests spices such as jeera (fennel seeds), ajwain (carom seeds) and saunf (sweetennel seeds), along with fermented drinks such as kanji rice or homemade pickles.
Dr. Dipak Bhangale, liver and endoscopy specialist at Kokilaben Dhirubhai Ambani Hospital, Navi Mumbai, also affirmed the essential role of the intestines in the immune system.
He said the gut microbiome regulates the immune response and is the first line of defense against viruses, including common cold viruses such as rhinovirus.
When the microbiome is unbalanced due to unreasonable diet, stress or antibiotic abuse, the immune system will reduce its ability to fight infections.
To protect gut health and prevent colds, Dr. Bhangale recommends eating plenty of fiber, a variety of vegetables, fruits, and fermented products like yogurt.
At the same time, limit sugar and processed foods to avoid feeding harmful bacteria. Getting enough sleep, managing stress, and consuming probiotics when necessary are also very important.
A healthy gut microbiome not only improves immunity but also reduces the risk of common colds, helping the body maintain an effective immune system against pathogens. Investing in gut health is investing in your overall health.
