Introduction

RIZWANA PATEL ACCESS BIOLOGY YOU ARE WHAT YOU EAT AND DO NOT EAT ''You are what you eat.''1 The food we consume determines our physical and psychological health. The muscles in the body, and the blood flowing through the veins, are all supplied by the food that we consume. These foods also have an effect on the way the brain functions, and an effect on the body's performance. People might say they are hungry and genuinely believe it when in fact they are feeling sad. This is due to the lack of neuro- chemicals in the brain which carry messages and control nerve impulses. When the right types of food are eaten, the neuro- chemicals contained in the foods enhances mental capabilities such as defusing stress. The serotonin, dopamine and endorphin levels in the brain change. Dopamine is related with alertness, used for fast reflexes, ''mental energy''2 and assists with problem solving. Serotonin helps to improve the mood and is a regulating hormone. It is important that a well balanced diet is consumed, eating an appropriate amount from each food group. Today's diet has drifted a long way off the ideal intake and balance of nutrients. Research will focus on a wide variety of diet related issues and its effect on the bodily systems.

''Overweight and obesity are increasing. The percentage of adults who are obese has roughly doubled since the mid-1980's''.7 As a desperate measure for losing weight, more and more people are attracted to low carbohydrate diets such as the Atkins diet because weight loss is instant. ''It is not healthy''. 60% of our diet should be from carbohydrates. Atkins diet only allows a very small amount of fruit and vegetables which is not enough to give the RDA. Essential vitamins and minerals come from a balanced diet and low carbohydrate diet is not balanced. The Atkins diet claims to clear up all manner of ailments, but it is lacking in nutrients essential for good health and a high protein diet increases calcium output, therefore a risk of osteoporosis. OSTEOPOROSIS occurs if the bones are not strong before bone loss begins. Calcium intake is important in achieving peak bone mass and an adequate supply is vital to health, particularly in times of growth, e.g. Childhood, adolescence, pregnancy and during lactation. Calcium is the principal mineral in bones and teeth. Deficiency of calcium in bones can result from an inadequate supply of vitamin D resulting in rickets in children and osteomalacia in adults. Different foods supply different amounts of minerals.

Conclusion
