Nutrition and Food

Nutrients are those substances present in food that our bodies process and thus enable it to function. The nutrient requirements are influenced by factors such as age, growth stage and activity of an individual. Nutrients are so minute that it is not visible with the naked eye. Thus Nutrients are divided in two categories: Macronutrients (carbohydrates, protein, fats) and Micronutrients (vitamins and minerals such as calcium, iron and vitamin C). Macronutrients make up a majority of our diets and provide energy for us to move and function. On the other hand Micronutrients are chemical substances that we require in small amounts for healthy growth and development.
There are many nutrient-poor foods available nowadays that means they didn’t contain that much nutrition which is required by our body to function. But instead of that these food contains full of excess energy (kilojoules), but that is not nutritional. This excess energy means that the food will provide your body with kilojoules, but its null and void of other essential nutrients that your body needs to function.
