As the weather changes, everyone is prone to colds and coughs. While we have all heard about the benefits of vitamin C for colds, few of us are aware of a secret solution - Zinc! Zinc is helpful as it can reduce the severity and duration of respiratory tract infections. It soothes sore throats with its anti-inflammatory properties. It plays a pivotal role in supporting various functions of the body like the immune system, wound healing and maintaining overall health. It prevents viruses from growing in the body. Zinc is also known to boost the immune system and fight infections.

Notably, zinc is a vital mineral found in a variety of plant and animal foods. When consuming zinc-rich foods during a cough and cold, prioritise moderation and diversity in your diet. Include lean meats, poultry, sea food, dairy, nuts and seeds. Combine zinc-rich foods with vitamin C sources for enhanced immune support.

Phytates, a substance found in unprocessed whole grains hinder the absorption of zinc, thereby making it less available for the body to utilise. Hence, vegetarians should follow some cooking techniques such as soaking them for 5-6 hours to reduce the phytate content and increase the bioavailability of zinc. Organic acids in fermented foods aid in higher absorption, so always include foods in your diet like buttermilk and yogurt along with some zinc-rich vegetarian sources.

It is important to remember that a higher dosage of zinc supplement inhibits the absorption of other minerals. Therefore, it is always good to check with the healthcare professionals while taking supplements. Stay hydrated, choose cooking methods that preserve zinc, and be aware of factors like phytates affecting absorption.
