Nutrition and Digestive System Quiz

Study Notes

Food Safety and Labeling

The Food and Drug Administration (FDA) is the government agency responsible for ensuring the safety, wholesomeness, and proper labeling of foods.
The FDA enforces federal laws that regulate the production, processing, and marketing of foods in the United States.

Calorie Measurement

There are six essential dietary constituents that can be measured calorically:
- Carbohydrates
- Protein
- Fats
- Fiber
- Alcohol
- Water (although technically not a "nutrient" in the traditional sense)

Water-Soluble Vitamins

Water-soluble vitamins are those that dissolve in water and are not stored in the body.
Examples of water-soluble vitamins include:
- Vitamin C (ascorbic acid)
- Vitamin B complex (thiamin, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folate, and cobalamin)

Macro- and Trace Minerals

Macrominerals are minerals that the body needs in large amounts.
Examples include:
- Calcium
- Phosphorus
- Magnesium
- Sodium
- Potassium
- Chloride
- Sulfur
Trace minerals are minerals that the body needs in smaller amounts.
Examples include:
- Iron
- Iodine
- Zinc
- Copper
- Manganese
- Fluorine
- Selenium
- Chromium
- Molybdenum

Survival Depends on Water

Water is the most important dietary constituent for survival.
It is essential for all bodily functions, including:
- Transporting nutrients
- Regulating temperature
- Removing waste
The human body can survive for several weeks without food, but only a few days without water.
