5 Signs of Good Nutrition

Good nutrition is necessary for optimal health, growth and life functions. Physicians look to signs and symptoms like height and weight, mental confusion or skin disorders to determine whether a patient has a nutritional deficiency. A healthy child or adult who consumes all the necessary vitamins, minerals and micronutrients will exhibit at least five signs of good nutrition.

Growth

Regular growth in height and weight is the primary indicator of good nutrition in children, according to the Clemson University Cooperative Extension. Short height or low weight for children under age 10, and low body mass index for children over age 10, indicates past or chronic malnutrition, according to the Emory University School of Public Health. Childrens' height, weight and body mass index charts, such as those established by Steven B. Halls, M.D., assist parents and physicians in determining children's health and nutritional status.

Skin

Clear, supple skin is a positive sign of good health and nutrition, according to the College of the Siskiyous. A deficiency of vitamin C can cause dry, rough skin, while insufficient B vitamin intake can cause dermatitis and skin disorders, according to the Colorado State University Cooperative Extension. Eczema and scalp disorders such as dandruff also might indicate a lack of essential fatty acids, according to Dr. Sarah Myhill, a family practitioner in Wales.

Muscles

Good muscle tone and a lack of soreness in muscles and joints indicates nutritional health. Tender calf muscles, muscle cramps and shaking hands can indicate a magnesium deficiency, according to Dr. Myhill. Vitamin C deficiency can lead to sore joints and bones, while a lack of biotin can cause muscle pain, and insufficient vitamin B-12 intake might cause tingling in the fingers and toes, according to the Colorado State University Cooperative Extension.

Mental Stability

Mental confusion can indicate vitamin B deficiency, and the inability to remember dreams might relate to a vitamin B-6 deficiency, according to Dr. Myhill. Insufficient intake of pantothenic acid contributes to difficulty sleeping, while a lack of niacin can cause mental confusion and irritability, according to the Colorado State University Cooperative Extension.

Vision

Not all vision problems are related to nutritional deficiencies, but good nutrition strongly supports good eyesight and ocular health. Bright clear eyes with no circles underneath is a clinical sign of good nutrition, according to the College of the Siskiyous. Sensitivity to light can indicate a magnesium deficiency or a lack of riboflavin, and poor night vision can indicate insufficient zinc intake. Vitamin A is critical for good vision and eye health, according to the Colorado State University Cooperative Extension.
