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.

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.
