A healthful diet is... – Adequate– means that the diet provides sufficient energy
and enough of all the nutrients to meet the needs of healthy people.
Balanced– The art of balancing the diet involves consuming enough— but not too
much—of each type of food
Varied (Colourful)- eat food from different groups
kCalorie (Energy) Control= kcalorie control is to select foods of high nutrient
Nutrient Density is good because foods in it that deliver the most nutrients for
the least food energy.
1 cup of milk provides about 300 milligrams of calcium, and 1⁄2 cup of fresh,
cooked turnip greens provides about 100 milligrams. Thus
a serving of milk offers three times as much calcium as a serving of turnip greens.
To get 300 milligrams of calcium, a person could choose either 1 cup of milk or
11⁄2 cups of turnip greens.
Another valuable way to evalu-ate foods is to consider their nutrient density—
their nutrient contribution per kcalorie. Fat-free milk delivers about 85 kcalories
with its 300 milligrams of cal- cium. To calculate the nutrient density, divide
milligrams by kcalories:
300 mg calcium
= 3.5 mg per kcal 85 kcal
Do the same for the fresh turnip greens, which provide 15 kcalories w
