Your body's signs of nutritional deficiencies

Updated: Apr 15

One of the doctors I am following, listening and reading on a regular basis is dr. David Jockers. I recently saw a post from him about the signs of nutritional deficiencies. And since one of my friends asked me as well if I could share information about vitamins and minerals, how to get them from foods and which foods, I thought of sharing these both in the below post. Below foods list is not comprehensive, but the top sources for these nutrients (as per Dr. Axe).

What are signs of nutritional deficiencies and how to rectify them with food?

From a nutrition point of view if you consume a wide variety of foods, you will make sure your body gets what it needs:

- eat healthy protein, including plant-based and animal-based

- consume regularly prebiotic and probiotic foods

Fat-soluble vitamins

To absorb fat-soluble vitamins through the intestinal tract in the body, it's important to consume them together with fat. Your body stores fat-soluble vitamins in liver and fatty tissue. Reserves of these vitamins can stay in the body for a while.

What vitamins and minerals you need to consume together?

  • Vitamin D + Calcium (vitamin D helps absorb, carry and deposit calcium into bones)

  • Iron + Vitamin C (vitamin C enhances the absorption of iron)

  • Vitamin B12 and B9 (folate)

  • Vitamin D + Omega 3

  • Magnesium + Vitamin D

  • Vitamin D + Vitamin K2

  • Vitamin K2 + Calcium

What vitamins and minerals you should not consume together?

  • Calcium + Iron (for example it's not good to consume heavy meat and cheese together)

  • Vitamin E + Vitamin K (excess amounts of vitamin E can reduce the absorption of vitamin K)

  • Iron + Copper + Zinc (if there is an excess of one in the food, it crowds out the others from making it through the intestinal wall)

I hope the above is a good guide for you to understand the basics of vitamins and minerals and from which foods to get them. As you most probably realised, if you eat a well-balanced diet, where you incorporate a wide variety of foods, you'll make sure your body gets all the nutrients it needs.
