Unfortunately, life isn’t like that, and the role of lifestyle and diet in diseases has been greatly exaggerated. Many people’s lives have been made a misery by faddish, short-term, impractical and ultimately useless diets – and others have become very rich. Diseases are due to our ancient natural defence mechanisms either breaking down under stress or overreacting to our environment. We all inherit these defences from our ancestors through the transfer of genes. Many modern diseases are due to a crucial interaction between our ancient genes and recent changes to our environment and lifestyle – which they weren’t designed to cope with. A good example we shall explore later is being fat: Genes that allowed you to maintain weight in times of hardship were a great advantage, but, now we are surrounded by too much food, they can be a major disadvantage. If you know at an early age that you are predisposed to obesity, avoiding certain foods and knowing you need to burn more calories could prevent the weight gain that may change your body’s metabolism forever. Overall, your family history is an infinitely better indicator of your future risks of disease than how many carrots or vitamins you eat per week.The word “faddish” (Para. 2) probably means ________.A. convenient to cookB. widely-known and acceptedC. very healthyD. fashionable only for a short time
