What happens to nutrients when cooked?

Heat diminishes vitamins and phytonutrients (beneficial plant compounds other than vitamins or minerals) in fruits and vegetables. The longer they cook, and the higher the temperature, the greater the nutrient destruction. Even chopping food can begin to erode some of the nutrients.

How does the nutritious value of food gets lost during cooking?

Minerals get lost when food is first cut, then washed and the extra water in which they are boiled, is thrown away. Nutrients like vitamin B and C are lost when foods are boiled or soaked in water and the water is thrown away. Nutrients like vitamin A are lost when fats are used for cooking foods.

Does food lose nutrients when cooked?

Cooking can indeed decrease certain nutrients in food, especially water-soluble ones like vitamin C and B vitamins (4, 5 ). Cooking also helps inactivate or destroy some harmful compounds in food. For example, cooking grains and legumes reduces lectins and phytic acid.

How does frying affect nutrients?

The frying process relies on high temperatures and can changes the structure of labile nutrients, such as proteins, vitamins and antioxidants. Some water-soluble molecules, such as ascorbic acid can be lost during the water evaporation.

How nutrients are lost?

Nutrients can be lost in a number of ways. Soluble nutrients like nitrate and potassium can be lost in runoff and drainage water, whereas less soluble nutrients like phosphorus are more likely to be lost with sediments moving in eroding soils and run-off water. Broadcast fertilisers on the soil surface are at risk.

How does poaching affect the nutrients in food?

Fat tends to drain away from foods, reducing calorie content as well as fat soluble vitamin content. Poaching, as opposed to boiling, is the gentle heating of a food in water. Typically an acid is also added to the water (wine, vinegar, citrus juice) and this can impact on acid/pH sensitive vitamins such as vitamin K.

How does food processing affect nutrients?

The nutrient value of food is almost always altered by the kind of processing it undergoes. The water-soluble vitamins are the most vulnerable to processing and cooking. Careful cooking and storage will help retain the nutrients in your food.

What are the advantages of cooking?

When you prepare your own meals, you have more control over the ingredients. By cooking for yourself, you can ensure that you and your family eat fresh, wholesome meals. This can help you to look and feel healthier, boost your energy, stabilize your weight and mood, and improve your sleep and resilience to stress.

How does the way you cook food affect its nutritional value?

The way you cook food plays an important role in how much nutrients your body is actually getting. Eating raw foods are considered to be the healthiest for the body as cooking through conventional methods such as deep frying, pan cooking or baking can lead to a significant nutrient loss.

How do you preserve nutrients when cooking food?

Learn more about cooking methods that preserve nutrients so that all the healthy vitamins stay for dinner. #1: Steaming. Steaming is the gentlest and healthiest way to prepare food. The hot steam cooks your food particularly gently, which means that valuable vitamins and minerals are preserved.

What are the advantages of alternative cooking methods?

Alternative cooking methods such as grilling, roasting, steaming, stir-frying or microwaving generally preserve a greater amount of vitamins and other nutrients. It would be inaccurate to say that cooking food always lessens the nutrient value. Cooking can be advantageous in many ways, including:

Does sautéing or frying improve absorption of vitamins?

Sautéing and stir-frying improve the absorption of fat-soluble vitamins and some plant compounds, but they decrease the amount of vitamin C in vegetables. Frying involves cooking food in a large amount of fat — usually oil — at a high temperature.
