concept of
diet
Your
diet is, quite simply, what you eat. There are two aspects to
your diet: what foods you eat and how much of them you eat. To
lose weight or maintain a healthy weight, you need to pay
attention to both factors. If you eat all the right foods but
they are in quantities that are too large, you will take in too
many calories and will gain weight. If you eat the right amount
of calories but you get them from only one food group, you will
lack essential nutrients which may cause serious health
problems.
The key to obtaining all the nutrients that
your body requires is eating the right mix of foods: a
balanced diet. This means eating a variety of foods
from different food groups that together contain all
the vitamins, minerals, and fuel (in the form of the
macromolecules carbohydrates, proteins, and fats) your
body needs. However, there is not one particular diet
that is the best for obtaining all these required
nutrients. Vegans, vegetarians, people with diabetes,
those with food allergies or celiac disease all have
very different diets but can all obtain proper
nutrition from what they eat.
