Why Zinc aside from Vitamin C is good for Senior Immunity?

Senior Family

 / Immunity Is Key

As we age, our body deteriorates, becoming less efficient at the tasks they were made for. A bad diet, unhealthy lifestyle and lack of exercise can accelerate the decline of these processes. Statistics show that 40% of elderly Filipinos suffer from Zinc deficiency, one of the leading causes of immune system deterioration in humans. 

In order to keep our immune system healthy, we have to provide it with the necessary building blocks like Zinc and Vitamin C. Among these two, the one we hear more about is Vitamin C. However, Zinc plays such a crucial role in our immune system that it is recommended to take it with Vitamin C.

These are the recommended daily intake of these nutrients for seniors (60+ y/o):

Zinc - 6.5mg for male, 4.6 mg for female


To put this in perspective, a 40 gram lean roast beef contains approximately 3.3mg of Zinc (50.77% DV* for male; 71.74% DV for female), while a 40 gram pork chop offers 1.45mg of Zinc (22.3% DV for male; 31.5 DV for female).

*DV - daily value / recommended serving of Zinc per day


If one does not consume the recommended daily value of Zinc, there is a very high risk of Zinc deficiency. This is more prevalent among seniors because of the lowered intake of food consumption (lower Zinc intake), the decreased absorption of nutrients in the body due to ageing and the consumption of rice (a staple in Filipino diets), which contain Zinc absorption inhibitors. 


Zinc deficiency can cause many different problems in the body, from superficial to severe. 

  • Hair loss
  • Scaly rashes
  • Poor appetite
  • Poor wound healing 
  • Diarrhea
  • Increased risk of infections (such as pneumonia) 

By following a proper diet, you can get the full benefits of zinc including boosting the immune system which is the most important. Here are the best sources of Zinc we can find among Filipino foods

  • Oysters
  • Crabs and Lobsters
  • Red meats (Beef and Pork) 
  • Whole grains (oats and brown rice)
  • Beans


However, because ageing also decreases appetite, food might not be enough so it is important to get your recommended daily intake of Zinc from other sources too.
