Doctor explained why garlic is useless in fighting colds

Nutritionist debunked the myth about "miracle" foods against the common cold

Australian nutrition expert Nina Imad from Swinburne University has refuted the widespread belief that certain foods can quickly deal with cold symptoms. Despite the immunomodulatory properties of some of them, there is no "magic" food for instantly strengthening immunity, reports Medical Xpress.

"Building a strong immune system is a long-term process that requires a comprehensive approach: adequate sleep, regular physical activity, stress management, and a diverse diet," the nutritionist emphasized.

"Oranges and other sources of vitamin C, including kiwi, berries, broccoli, and greens, are indeed beneficial, but taking ascorbic acid after cold symptoms appear does not have a pronounced effect. Only its regular consumption may slightly reduce the duration of the illness," the nutritionist explained.

The doctor added that some studies indicate the presence of immunomodulatory effects in garlic. However, there is no convincing evidence of the effectiveness of supplements based on it in fighting colds.

"Zinc can be of great benefit. Taking supplements with it at the beginning of the illness can reduce its duration. Good natural sources of zinc are meat, shellfish, legumes, nuts, seeds, and dairy products," the doctor specified.

Dr. Imad added that to protect against colds, it is important to prevent vitamin D deficiency in the body. This vitamin is critically important for the normal functioning of the immune system. It is found in fatty fish, eggs, mushrooms, liver, and specially fortified milk.
