Which of the following methods is used to increase the nutritive value of food?

✅Explanation: Fortification is the process of adding essential vitamins and minerals (micronutrients) to food to improve its nutritional quality. This is done to address deficiencies in the population's diet and promote public health. For example, milk is often fortified with vitamin D, and salt is fortified with iodine.

📌Other Options Explanations:
Pressure cooking: Pressure cooking is a method of cooking food quickly using high pressure and steam. While it preserves some nutrients better than boiling, it doesn't increase the nutritive value of food.
Canning: Canning is a method of preserving food by sealing it in airtight containers and heating it to kill bacteria. This process can lead to some nutrient loss, particularly of heat-sensitive vitamins like vitamin C.
Baking: Baking is a dry-heat cooking method that involves heating food in an oven. While baking can be a healthy way to cook, it doesn't increase the nutritive value of food.

🛑 Additional Information:::
Fortification means deliberately increasing the content of essential micronutrients in a food so as to improve the nutritional quality of food and to provide public health benefits with minimal risk to health.
Voluntary fortification allows food manufacturers to choose what vitamins and minerals they add to food, as long as there are permissions in the Code.
For example, breakfast cereals are allowed to be fortified with a range of vitamins and minerals.
It helps to control increasing health problems like heart disease and diabetes.
The amounts that can be added are also regulated.
