Non Nutritive Items |
Dietary fiber is not a nutrient, but it is necessary to regulate digestion and appears
to prevent some epidemiological diseases.
A loose term denoting the substances in plant food that are not digested by human
digestive enzymes. It provides almost no calories. It is necessary for an individual
to drink 8 glasses of water daily and more if participating in sports or exercising.
Water is the most critical nutrient for sustaining life. Two-thirds of the human
body is water. As a comparison, our bodies are 60% water by weight; raw meat is
about 75% water and fruits and vegetables up to 95% water. It may take us weeks
to starve, but only a very few days to dehydrate. About 3/4 of our water is contained
within individual cells.
