A word about nutrition



Why eat ?

Eating puts you directly in control of your own health, and it provides pleasure.
Foods contain the nutrients that are essential to good health.They provide energy & allow your body to grow. These nutrients areproteins, carbohydrates, fats, vitamins, minerals and water.

Each person's daily caloric needs are specific.The calories you need depend on your height and weight, your activity level and wether you want to lose, gain or maintain weight.

What is good nutrition ?

Good nutritient involves eating a variety of foods, because no one food will supply all the nutrients your body needs. The 4 main food groups are : 1. Fruits and vegetables, 2. Whole grains, cereals and breads, 3. Dairy products and 4. Meat, fish, poultry, eggs, dried beans and peas. Eating from each of the food groups everyday will help prevent any nutrient deficiency.

Experts recommend a daily calorie intake of 50 to 60% carbohydrates, not more than 30% from fats and the remainder from protein. These rules refelect a new emphasis on limiting fat & increasing carbohydrates, especially carbohydrates and fiber rich foods like whole grains, legumes & vegetables.
