carbohydrate foods‚ this only recognized the food to be high in a particular nutrient. In fact‚ foods are mixtures of different nutrients and other chemical substances such as toxins‚ pigments and additives. Protein‚ carbohydrates and fat are regarded as macronutrients due to the size of their molecules. These nutrients are needed in large quantities in the body to enable the body to function properly. Vitamins and minerals are required in lesser amounts but are equally necessary and must be obtained from the

nutrients for plant growth are carbon‚ hydrogen and oxygen. These nutrients are uncontrollable unless grown in a closed area or with artificial settings. There are thirteen other minerals which can be separated into two group’s micronutrients and macronutrients.

that a growing body of scientific evidence indicates that wholesome vegetarian diets offer distinct advantages compared to diets containing meat and other foods of animal origin. The benefits arise from lower intakes of saturated fat‚ cholesterol and animal protein as well as higher intakes of complex carbohydrates‚ dietary fiber‚ magnesium‚ folic acid‚ vitamin C and E‚ carotenoids and other phytochemicals.

oxygen atoms. Based on the arrangements of these atoms‚ fats are grouped into: saturated‚ poly-unsaturated‚ mono-unsaturated and trans. Macronutrients‚ Oxidation and Energy Fats‚ carbohydrates and proteins are regarded as macronutrients because the body usually extracts other nutrients from them. In addition to supporting body growth‚ development and repair‚ macronutrients give us energy. This energy is measured in calories. When fat‚ carbohydrate and protein undergo oxidation‚ carbon-dioxide‚ water and

The aim of the experiment was to examine the effects that having a rich lipid diet had on the CHO and fat metabolism during the prolonged exercise. The data shows that at rest the body was in a heavy fat metabolism and when exercise started there was a shift of metabolism from fat to CHO. After thirty minutes‚ the metabolism shifted back to a primary metabolism of fat. Examining the data from this experiment to other studies showed a similar result.

Carbohydrates ● Carbohydrates are one of three classes of food called macronutrients. ● The basic unit of a carbohydrate is a simple sugar‚ but these simple sugars can be linked together in infinite ways‚ and will have very different effects on the body depending on their arrangement. ● Examples of carbohydrates include; pasta

suicide or depression (Wells 24). Several clinical and intervention trials examining the effect of low-fat diets on weight indicate that diets lower in fat can result in modest reductions in body weight in the short-term‚ but in the long run energy intake from fat has a negligible effect on body weight (Harvard Women ’s Health Watch). The Harvard study‚ of nearly 50‚000 women‚ found that eating low-fat diets for eight years offered no health benefits — no lowered risk for heart disease‚ stroke‚ colon
