1. How can you define healthy eating?
Healthy eating is about eating a variety, balance and moderate diet.
A variety of foods should be eaten using the Healthy Diet Pyramid as a guide to get all the needed nutrients. A single type of food fails to supply all the nutrients the human body requires to stay healthy. Hence it is important to enjoy a variety of foods from the food four groups, as well as within each food group.
2. Should the intake of nutrients vary according to the size of a person?
Every individual need the same nutrients but in different amounts depending on age, gender and body size. Children and teenagers need more of certain nutrients for growth while men, due to their larger body size, usually need more of most nutrients than women.
3. How to calculate the calorie level of a particular food?
Nutrients that contribute to the energy values in food include carbohydrates (1g= 4kcal), protein (1g= 4kcal), fat (1g= 9kcal) and alcohol (1g = 7kcal). Therefore, the calories from each of these components make up the total calories of the food.
4. What are fast foods? Are they healthy?
Fast foods are a term commonly used to describe foods that are fast to prepare, serve, and eat. Burgers, hot dogs, pizza, French fries, fried chicken, pies and pre-packed meals are generally regarded as fast food.
