Different Types Of Fat That A Food Can Contain
Fats too provide us energy. They are of two types: saturated and unsaturated.
Saturated fats are normally solid at room temperature [ (e.g., butter), whereas unsaturated fats are mostly liquid at room temperature (e.g., vegetable oil). Meat, oil, ghee, nuts, butter and cheese are some sources of fats. Milk, fish, and egg also contain fats.
Though fats are essential for our body, eating too much of food items rich in fats can be harmful. Excess body fat leads to a condition called obesity. Obesity may also lead to heart diseases.
Activity
Aim: To test the presence of fat in a food item.
Materials needed: Food sample and a sheet of filter paper.
Method:
If the food sample is liquid, rub a small amount of it onto the filter paper. If the food sample is solid, keep it between the folds of a filter paper and crush it.
Observation: Oily stain appears on the filter paper.
Conclusion: The appearance of oil stain confirms the presence of fats.
Starch: Starch is also called complex carbohydrate. Plants store energy in the form of starch. Rice, wheat, corn, potato, and bread are some sources of starch. When we eat plant products, containing sugar and starch, our digestive system breaks them down into glucose. This glucose, which is the simplest form of sugar is then absorbed into the blood and provides us energy.
