Answer 2

Answer:

1.All the six nutrients present in the food are as follow:

Proteins.

Vitamins.

Carbohydrates.

Fat.

Water.

Minerals.

2.Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy.

3.Protein is important for growth and repair of body cells. Food sources of protein include meat, fish, dairy, lentils, beans, and tofu. Insufficient protein can lead to low growth and a weakened immune system. Excess protein may lead to weight gain and liver problems

4.The WHO divide these essential nutrients into two categories: micronutrients and macronutrients. Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals.

5.The key is to focus on eating healthy fats (in moderation) and incorporate a variety as part of a well-balanced diet. Because fats are much higher in calories than other foods, at nine calories per gram, it is important to eat them in small amounts to prevent weight gain and limit negative health effects.

6.All foods have to list seven food components on their nutritional information panels – energy (kilojoules), protein, total fat, saturated fat, total carbohydrates, sugars and sodium. Manufacturers might decide to include other nutrients too, including fibre and calcium
