WE always presumed that virus or bacteria always makes us sick or feeling weak.
However, not all “illnesses” are caused by bacteria or any pathogen. They may be caused by weakening immune system or nutrition deficiency.
Here are some common signs you may be nutrition deficient:
* Poor night vision. Vitamin A, known as retinol, is essential for promoting good vision and overall eye health. It also helps to maintain healthy skin and soft tissues throughout the body.
* Cracks at the corners of the mouth. This is more likely to occur for those following vegan and vegetarian diets because it's harder to get sufficient zinc, iron and B12.
* Sores or discoloration of the mouth and tongue. Water-soluble B-vitamins are essential for the health of the mouth and tongue. Unfortunately, the body doesn't store them, so we have to constantly replenish them to maintain health.
* Weak, spotted or ridged nails. These are common signs of a deficiency in zinc, an important trace mineral needed for the proper function of the immune system. Zinc also serves an important role in cell division and growth.
* Poor blood clotting. Essential for normal blood clotting, vitamin K also plays a vital role in bone mineralization and cell growth. Lack of vitamin K can result in bruising, frequent nosebleeds and brittle bones.
* Weak muscles and bones. In advanced cases it's called rickets (for children) or osteomalacia (for adults), but it boils down to a defiency in vitamin D, an essential nutrient for growth, health and maintenance of the structural system.
* Frequent cramps in the lower legs. Magnesium, calcium and potassium support proper muscle development and growth. Lack of these important nutrients can cause persistent discomfort in the feet, calves and back of the leg.
