Why you Should Include Zinc-Rich Foods in Your Diet?


Recently, due to the COVID-19 pandemic, people are looking out for natural ways to boost their immunity. Of course, when we talk about immunity, Vitamin C is the first thing that comes to our mind. However, very few know that zinc-rich foods are equally essential for our immunity and play a significant role in keeping us healthy.

Zinc is a trace mineral, which means that our body requires it in tiny amounts. Zinc is necessary for the activity of over 300 enzymes, protein synthesis, wound healing, cell growth, and a healthy immune system. Unfortunately, our body cannot synthesise zinc, and we need to consume zinc-rich foods regularly in small amounts for proper growth and functioning.

Zinc deficiency is prevalent and leads to a weak immune system. Therefore, it is essential to consume zinc-rich foods to supply our bodies with adequate zinc minerals. Zinc-rich foods are readily available, and there are various options for both vegetarians and non-vegetarian people. Consume zinc-rich foods at least two to three times a day to achieve optimal zinc levels in your body.

Here is everything that you need to know about zinc-rich foods and their benefits:

  • Women – According to NIH, the daily consumption allowance of zinc for women is 8 mg.
  • Pregnant Women – Pregnant women need more zinc for the proper growth and development of the foetus. Therefore, the daily recommended dose of zinc for pregnant women is 11 mg.
  • Breastfeeding Women – For breastfeeding women, it is 12 mg.
  • Men – The daily allowance of zinc for men is 11 mg.

Health Benefits of Eating Zinc-Rich Foods

1. Improves Immune System

Zinc activates the T- cells in our body that are important for proper immune function. An inadequate amount of zinc in the body can weaken these immune cells. As a result, people deficient in zinc suffer from low immunity and are more susceptible to falling sick, recurrent infections, skin conditions, and other chronic diseases.

2. Boosts Eye Health

Zinc activates Vitamin A, which is essential for good eye health. Zinc can reduce inflammation and oxidation and improve eye vision. Zinc-rich foods can significantly improve your overall eye health.

3. Promotes Wound Healing

An adequate amount of zinc in the body helps to fasten the process of healing. For example, it helps treat infections and heals the wounded skin. Conversely, low levels of zinc in the body lead to a delay in wound healing.

4. Promotes Skin Health

Zinc has anti-inflammatory properties that help treat various skin conditions, like acne and skin infections. Eat zinc-rich foods daily to get rid of acne naturally.

5. Promotes Muscle Growth and Repair

Zinc promotes cell growth and maintains muscle health. It also helps release the growth hormone, testosterone, and encourages muscle mass building and fastens muscle repair.

7. Aids in Nutrient Absorption

Zinc helps in protein synthesis. It also helps to break down carbohydrates from the food and release energy. People with a low level of energy and fatigue usually have low levels of zinc in their bodies.
