Dairy
| Quick
Tip: Consuming a daily requirement of calcium
in cheddar cheese would be equivalent to 700 calories, mostly
from fat, but meeting your calcium needs from non-fat milk
comes with fewer than 350 calories and almost no fat. If you
are trying to limit your fat and calories, choose lower fat
dairy products such as skim (fat-free) milk, or 1% (low-fat)
milk, lower fat or reduced fat cheeses, and low-fat yogurt. |
Why do we need it?
Dairy products are good sources of carbohydrates, protein, calcium, vitamins
A & D, magnesium, potassium, phosphorus and B vitamins. Our body
absorbs the calcium from dairy products better than most foods. Calcium
is essential in optimal bone health (including teeth), and it also
functions in nerve transmission, maintaining optimal blood pressure,
muscle contraction (including the heart), blood clotting, secretion
of hormones and enzymes, and decreasing risk of some cancers. Because
calcium is essential to proper functioning of the heart among other
roles, if we do not consume enough through foods (or supplements),
our body will obtain the calcium it needs from our bones, leaving them
weak and brittle and increasing our risk of stress fractures, breaks
and osteoporosis.
How much do we need?
Most healthy individuals need approximately 1000-1200 mg of calcium
every day, although pregnant women, lactating women and adolescents should
try to consume 1500 mg/day. One serving of milk, yogurt or cheese has
about 300-500 mg each therefore we should consume an average of 3 servings
every day. Other foods that are also good sources of calcium include
calcium-fortified cereals, snacks, juices and soy products, canned sardines
or salmon, beans, oysters and vegetables.
Optimal calcium intake is important in children to ensure proper development
and growth of their bones. Adults and children (especially if vegetarian)
may need to take calcium supplements regularly if their diets do not
provide enough. A variety of excellent calcium supplements exist on the
market today in both chewable and pill forms. Calcium supplements should
not be taken with other supplements that may include iron, because these
two minerals inhibit the absorption of one another.
