Doctor explained why garlic is useless in fighting colds

Individual products, such as oranges or garlic, are not capable of alleviating cold symptoms, despite having immunomodulatory properties. This was warned by nutritionist Nina Imad from Swinburne University (Australia). The expert's words are cited by Medical Xpress.

According to the expert, there is no "magic" food that could quickly strengthen immunity. The doctor clarified that building a healthy immune system takes more than one day. Maintaining its function requires regular sleep, physical activity, ability to cope with stress, and diversity in the diet.

"Oranges and other sources of vitamin C, including kiwi, berries, broccoli, and greens, are indeed beneficial, however, taking ascorbic acid after cold symptoms have already appeared does not produce 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 bring great benefits. 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.
