For French fries, baking French fries in the oven is definitely much healthier than French fries. First of all, when cooking in an oven, it is generally only necessary to pour cooking oil on the surface of French fries and stir them to cover them evenly. This avoids the use of a lot of cooking oil. Secondly, there is no high-temperature frying, which avoids unhealthy substances produced in this process. For the taste of the finished product, baked potato chips and sweet potato chips are actually very good. Try the oven version of homemade French fries when you are greedy.
For meat, oven heating is not as healthy as stewing, boiling and frying. When cooking in an oven, under the action of high temperature, meat will produce heterocyclic aromatic amines, such as polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amine compounds (HAA). Heterocyclic aromatic amines increase the risk of insulin resistance and diabetes. Of course, the most important factor in the production of heterocyclic aromatic amines is high temperature, which can be produced in the process of barbecue besides cooking in the oven. Therefore, it will be relatively healthy to cook by stewing, boiling and quick frying.
For vegetables, some vitamins and some phytochemicals are thermally unstable, that is, they are easily decomposed and lost at high temperature. When cooking in the oven, vegetables usually stay at high temperature for a long time, which will lead to the loss of some vitamins and the decomposition of phytochemicals. However, vegetables have high nutritional value after all. If baking vegetables is the only accepted cooking method for some vegetables, it is not recommended not to eat vegetables because of losing some vitamins. After all, the nutrition and health value brought by eating vegetables is far greater than the loss of these nutrients.
For baking, whether food is healthy or not depends largely on the raw materials used in the production process. If you add a lot of sugar, butter, cream, etc. The final product will be high in sugar and fat, which can't be blamed on the oven. Remember to taste this dessert in moderation ~
