This document discusses how diet and nutrition affect health. It explains that appetite is driven by pleasure from taste and aroma, while hunger is the body's physical need for fuel. Diet is a lifestyle pattern of what, how much, and when we eat. Poor diet choices can lead to short-term issues like mood swings and fatigue or long-term problems such as obesity, heart disease, diabetes, and cancer. Obesity occurs when more calories are consumed than burned and is a leading cause of preventable death. In conclusion, food choices significantly impact mind, body and emotions, so it is important to eat healthy.
