Good nutrition is essential for everyone’s health.  Without it, people cannot grow or function properly.  Nutritional deficiencies present themselves with plenty of symptoms that physicians look for, but can often go unnoticed.  Healthy individuals possess a few key characteristics that show they have optimal nutrition.  If you exhibit the following signs of good nutrition, you are probably in great health!

Proper growth 
This is a sign usually looked for in children (obviously adults are most likely done growing!) to ensure they get proper nutrition.  Short height or low weight for children under age 10 and low body mass index for children over age 10 can indicate a form of malnutrition.  Physicians do a good job of keeping track of children’s growth and will take action to determine underlying causes for growth problems.

Clear, supple skin
Clear, supple skin is a sign of good nutrtion. If your skin is unusually dry and rough, you may have a nutritional deficiency.  Other skin symptoms such as dermatitis and skin disorders can signal inadequate vitamin B intake.  All nutritional deficiencies portray themselves differently but if you begin having apparent skin problems, you should get it checked out.

Healthy muscles 
Certain nutritional deficiencies, especially ones in vitamin C, B-12 and magnesium can lead to tender muscles, muscle cramps and sore joints.  Good muscle tone and a lack and a lack or soreness in muscles and joints indicates nutritional health.

Good mental stability
Some individuals with poor nutrition possess mental confusion, sleeping disorders and other mood problems.  If you’re having problems like these, you may want to have your doctor screen you for nutritional deficiencies.

Strong vision
Good eyesight is a sign of good nutrtion.  Certain nutrients, like vitamin A, riboflavin, zinc and magnesium aid with good vision.  For example, eye problems such as poor night vision can be pinpointed to inadequate intakes of zinc. 

It is important to know that health problems, such as the ones above, don't always occur because of a nutritional deficiency, there can be several underlying causes—so don’t just assume you are malnourished.  But if you experience any of the problems listed above, whether it be with your skin, muscles, mental stability or vision, it would be best to see a doctor to rule out nutritional deficiencies.  To avoid nutrition problems, eat a well-balanced diet full of nutrient dense foods.  Your doctor may suggest for you to take a vitamin supplement if you cannot consume enough nutrients.
