Why is nutrition important?
The answer goes far beyond "You are what you eat."
Nutrition is important because it fuels your body and gives you chemical building blocks like amino acids for making protein and calcium and magnesium for building bones and teeth. It provides fatty acids for building the membranes of cells and their components.
Vitamins, Minerals and Enzymes
The vitamins and minerals nutrition provides act as co-factors for the enzymes that run almost everything that happens in your body. These important effects of nutrition have been the focus of scientific research for more than a hundred years.
Scientists have concluded that vitamins, minerals, amino acids and essential fatty acids are essential nutrients and that carbohydrates are the most efficient sources of fuel.

Recent research has revolutionized nutritional science by discovering other reasons why nutrition is important.
Nutrients in food can dramatically affect the way your body functions.
Key among these are the bioflavonoids and carotenoids that give food some of its richest colors: the deep blue of blueberries, the red of cherries and tomatoes and the orange of carrots. The antioxidants in these foods can provide protection against free radical damage, helping to protect against disease and aging.
With the growing body of scientific evidence, the importance of nutrition in prevention, wellness, anti-aging and combating disease is now beyond a doubt.
What we eat on a regular basis can contribute to various conditions. A major way diet impacts health is the case of obesity, diabetes and related diseases.

Learn which dietary patterns contribute to conditions, and a quick look at some nutritional approaches that can help:
Crohn's Disease and Nutrition
Diets high in sugar and white starch increase the risk of Crohn's disease, a type of inflammatory bowel disease.
What Can Help: For people who already have Crohn's disease, a high protein, low carbohydrate diet can improve long-term outcome.
Parkinson's Disease and Nutrition
High protein diets may possibly increase the risk of developing Parkinson's disease. In addition, the medication taken for Parkinson's disease tends to work better when people avoid animal protein.
What Can Help: Drinking coffee (but not decaf) may decrease the risk of developing Parkinson's disease (and also decrease the risk of developing Type 2 diabetes). People with Parkinson's disease may also need extra fat in their diets.

Gout and Nutrition
Diets high in animal flesh (red meat, poultry and seafood) can increase the risk of developing gout.
What Can Help: Control of gout once it develops may be easier if animal flesh is avoided. Eating cherries and drinking concentrated cherry juice can decrease the risk of gout.
Celiac Disease and Nutrition
About three million Americans have celiac disease, a genetic disorder that causes intolerance to gluten, a protein found in wheat (including white flour products), barley and rye.
Celiac disease can cause diarrhea, abdominal pain, fatigue, neurological and psychiatric problems, osteoporosis, skin rashes and joint pain, and can trigger a variety of autoimmune disorders and some cancers. Most people don't know they have celiac disease until they're specifically tested for it.
What Can Help: It is essential for people with celiac disease to follow a strict gluten-free diet for life.
The Sugar Trap
A variety of different conditions are adversely affected by eating food with added sugar (either sucrose or high fructose corn syrup). These include diabetes and its many complications, Meniere's syndrome, hypoglycemia, depression, inflammatory bowel disease, irritable bowel syndrome, vaginal yeast infections and fatty liver disease.
What Can Help: Avoiding foods with added sugar and corn syrup. Eating whole, unprocessed foods.
Intolerance or allergy to specific foods may trigger numerous disorders. These include:
- Canker sores
- Interstitial cystitis
- Vulvar pain (vulvodynia, vulvar vestibulitis syndrome)
- Infantile Colic
- Irritable bowel syndrome
- Colitis and ileitis
- Autoimmune disorders like Sjogren's syndrome and some cases of lupus
- Protein-losing enteropathy
- Failure to thrive
- Migraine headaches
- Attention deficit disorder, hyperactivity
- Nephrotic syndrome
- Fibromyalgia and chronic fatigue syndrome
- Mood swings
- Fever of unknown origin
- Type 1 diabetes
