Energy in food comes mainly
from three sources: carbohydrates, proteins, and fats. Individual foods are not
fattening, nor do they magically take off weight. What matters is the amount
and quality of food in your overall diet.
Bread is an excellent source of energy, and yet it can help you lose weight.
The secret is the dietary fiber in bread. High fiber foods take up more space
in the stomach, so there is less room and less need for high calorie treats.
The energy in bread is mostly in the form of starches, which are absorbed
slowly and keep you satisfied longer.
Recommended distribution of energy yielding
nutrients is:
Carbohydrates 55 %
Carbohydrates are the primary fuel
for your body, and for that reason they should form the core of your diet. The main
categories of carbohydrates are starches and sugars. Starches are broken down
gradually in your intestines and give out energy over a period of time. Good
sources of starch include bread, other grain products and potatoes. Increasing
starchy foods in your diet is beneficial because in addition to being a good
source of energy, starchy foods are packed with nutrients. Refined sugars, on
the other hand, should be limited to no more than 10% of the total energy
intake.
Fats 30 %
Fats have over twice as many
calories per gram (9 Cal/g or 38 kJ) as carbohydrates and proteins (4 Cal/g or
16 kJ). A high fat intake has been linked to obesity and cardiovascular
disease. For that reason it is recommended that fat intake should be limited to
less than 30% of total energy intake.
Proteins 15 %
Proteins are the building blocks
for your body. They consist of 20 different amino acids in different
combinations. 11 of those amino acids are essential, which means that we have
to get them from food. Animal-based foods contain the full range of amino
acids. From plant-based foods you can get them all by combining different
products. The need for energy from proteins is relatively small.
