Vitamin Deficiencies: Most People Have A Few.


Wishing you a very Happy Fourth of July!

Subclinical deficiency can be used to describe a nutritional deficit not yet far enough advanced to produce obvious symptoms. In lay terms, however, the phrase has become a handy explanation for common but hard-to-pin-down symptoms, such as fatigue, irritability, nervousness, emotional depression, allergies, and insomnia.

The good news is that the nutritional Recommended Daily Allowances (RDAs) are broad enough to prevent most serious vitamin deficiencies for those who eat a reasonably balanced diet.

Your body sends you signals when there is a vitamin deficiency. Here are some examples:

Vitamin A: A deficiency in Vitamin A can produce poor night vision; dry, rough, or cracked skin; dry mucous membranes including the inside of the eye; slow wound healing; nerve damage; reduced ability to taste, hear, and smell; inability to perspire; and reduced resistance to respiratory infections.

Vitamin D: Lack of this vitamin in children can result in weak muscles, delayed tooth development, and soft bones; adults can suffer from soft, porous bones that fracture easily.
