Many people often say that eating fried foods not only leads to weight gain, but also causes cancer. Is this true? Let's see what experts have to say.
Do fried foods really cause cancer?
(1) It is advisable to avoid cooking methods that involve high-temperature frying with oil, as the high temperature can destroy vitamins and denature proteins in fried foods.
Repeatedly heating edible oil at high temperatures can lead to oxidation, hydrolysis, and thermal polymerization, resulting in the formation of harmful substances such as aldehydes, low-level fatty acids, oxidants, and epoxy compounds.
These substances can damage the body's enzyme system and accumulate in the body over time, potentially leading to cancer.
(2) High-temperature frying also produces harmful free radicals, which can damage essential fatty acids in food and cells in the body, increasing the risk of cancer.
Therefore, it is recommended to minimize the use of frying and other cooking methods that involve excessively high oil temperatures, and instead opt for steaming, boiling, and stewing to reduce the likelihood of harmful substance formation and nutrient degradation in food.
What are the other hazards of eating fried foods?
1. Susceptibility to gastric problems
Fried foods are not easily digested, and excessive consumption can lead to gastric problems.
Oils heated at high temperatures can produce a substance called "acrylic acid," which is difficult to digest.
Eating fried foods frequently can cause chest discomfort, bloating, nausea, vomiting, or indigestion.
2. Vitamin B1 deficiency
Fried foods are often coated with a layer of flour paste before frying.
During high-temperature frying, vitamin B1 in the flour is completely destroyed, leading to a deficiency of this vitamin in the body when fried foods are consumed over a long period of time.
3. Increased risk of obesity
According to guidelines, the energy provided by fat in the daily diet should account for 25% to 30% of the total energy intake.
However, frequent consumption of fried foods exceeds this limit, leading to a higher intake of fat-derived energy and an increased risk of obesity.
