21

After You ReadReview Key Concepts

List the three main nutrient functions.

The six categories of nutrients are: carbohydrates, fats, proteins, vitamins, minerals, and water.



22


List food sources of carbohydrates, fats, proteins, vitamins, minerals, and water.Food sources of carbohydrates are grain products, such as breads, cereal, rice, grits, and pasta; starchy vegetables, such as squash, potatoes, and corn; and legumes, such as beans, peas, and lentils. Food sources of fat are meat, poultry, fish, dairy foods, and nuts. Food sources of proteins are food from animal sources, such as meat, poultry, fish, eggs, and dairy products or from soy for complete proteins, or plant sources such as beans, peas, grains, and nuts for incomplete proteins. Water can come from plain water, juice, milk, and soups, as well as most foods. Vitamins and minerals come from a variety of foods.



23


Explain energy balance.

Energy balance is consuming the same amount of energy, or calories, as your body uses. When you balance the energy from your food and drinks with the amount your body uses, you maintain your weight. If you eat more food and drinks than the amount your body uses, you gain weight. If you eat less food or drinks than the amount your body uses, you lose weight.



24


Describe the possible effects of getting too few or too many nutrients.Getting too few nutrients may result in poor health or a lack of energy. If you get too much of a nutrient, the body gets rid of extra water-soluble vitamins as waste. Extra energy from carbohydrates, proteins, or fats turns into body fat. If you take too many fat-soluble vitamins, as well as some minerals, they can build up in the body and create health problems.



25


Describe the safe use of dietary supplements.

Health professionals may recommend supplements for specific reasons including calcium supplements for people who are allergic to milk, or to some elderly people, pregnant or nursing women, people on certain medications, or those recovering from illness. Taking large amounts of these vitamins may cause health problems. Some water-soluble supplements can cause your kidneys to work too hard to remove the excess, while others may harm your liver and other organs.
