does food lose its nutritional value when cooked?
Cooking food can lead to changes in its nutritional content. Some nutrients are more sensitive to heat than others. Water-soluble vitamins, such as vitamin C and vitamin B1, can be lost when food is boiled or steamed. This is because these vitamins dissolve in water, and some of them may be lost when the water is drained off. Cooking can also destroy some of the enzymes that help the body absorb nutrients. For example, cooking meat can destroy the enzyme that helps the body absorb iron. However, cooking can also make some nutrients more available to the body. For example, cooking vegetables can break down cell walls, making it easier for the body to absorb nutrients like beta-carotene and lutein. Overall, the nutritional value of food can be preserved or even enhanced by cooking. By using the right cooking methods, you can preserve the nutrients in your food and enjoy a healthy and delicious meal.
why does food lose nutrients when cooked?
Cooking is a necessary part of life, but it can also lead to the loss of nutrients in food.

is it better to weigh food cooked or raw?
Raw and cooked foods can differ in terms of their weight. Understanding the changes that occur during the cooking process is essential in determining whether to measure food cooked or raw for accurate nutritional information. Cooking involves the application of heat, which can alter the water content, nutrient composition, and physical structure of food. Generally, cooking leads to a reduction in food weight due to factors such as evaporation, chemical reactions, and the breakdown of complex molecules. Certain foods, such as meat and poultry, may lose weight due to the release of fat and moisture during cooking. Conversely, foods that absorb liquids, like rice and pasta, tend to gain weight. The weight loss or gain during cooking can impact the accuracy of nutritional information if measurements are not taken appropriately. Weighing food in its raw state provides a more precise representation of the actual weight of the food you are consuming, including the full nutritional content. However, if a recipe or nutritional label specifies cooked measurements, it is important to follow those instructions to ensure accurate portion control and nutrient intake.
does blending food destroy nutrients?
Blending food does not destroy nutrients. In fact, it can help to make some nutrients more bioavailable, meaning they are more easily absorbed by the body.
