Main Nutrients Water Water makes up more than two-thirds of the weight of the human body and participates in keeping the body's normal temperature, lubricating our joints, protecting our tissues, and getting rid of body wastes through perspiration and urination. We obtain water by drinking natural water, tea, milk, or eating soups. Water consumption should be increased in hot climates, during/after a physical activity, or when affected by fever, diarrhea or vomiting. Calorie (energy) Balance Calories are units of heat expenditure. Energy is provided by proteins (4 calories/g), carbohydrates (4 calories/g), fat (9 calories/g): the macronutrients, and alcohol (7 calories/g). Overweightedness and obesity are the result of a consumption of calories greater than the amount of calories expended. Even small imbalances over time can result in weight changes. Making the right food choices and practicing a regular physical activity are the two main factors in controlling the energy balance and maintaining or losing weight. Proteins Proteins are for the growth and development of the body; maintenance and repair of worn-out tissues; and for the production of enzymes and hormones required for many body processes essential for to growth and maintenance. There are different sources of proteins: animal (meat, dairy, poultry, eggs, seafood) and vegetable (beans, nuts, peas, soy products, grains). It's important to combine the different types of proteins since the amino acid composition of vegetable proteins differs from that of animal proteins. Each My Cuisine deLight meal provides a combination of animal and vegetable proteins. Fat Fats (lipids) are part of a healthful diet but should not exceed 30% of the total caloric intake. They are a major source of energy and aid in the absorption of fat-soluble vitamins and carotenoids. High intake of saturated fat and cholesterol, most often from animal origin (butter, animal fat, whole milk, cream), increases the risk of coronary heart disease. Carbohydrates Carbohydrates are a major source of energy for the body and the preferred source of energy for the brain in the form of glucose. Complex carbohydrates (starches) are chains of simple carbohydrates that are broken down by the digestive enzymes. Dietary fibers are non-digestible carbohydrates that have beneficial effects, such as: to lower the risk of diabetes and heart diseases, and an improvement in laxation.
