Nutrition is the process of eating and drinking, and how this influences our health. Within nutrition, our diet is the food and drink we normally consume. Some dietary choices may be more healthy than others. Obesity is the accumulation of excessive body fat that can impair health.
Nutrition is an essential part of health and development. A balanced diet provides all the nutrients needed for growth and repair, helping to prevent illness and keeping people strong and healthy.
Obesity is generally caused by consuming more calories than are burned off through exercise and other physical activity. Excess energy, particularly from fatty and sugary foods, is stored by the body as fat, leading to a high BMI (Body Mass Index).
