The speed at which a person ages is mainly determined by genes, but some of the foods we eat can play a role in accelerating or slowing down the aging process. Sun Shuxia, president of the Nutrition and Safety Professional Committee of the China Health Care Association, believes, "Health is built bite by bite, and longevity is accumulated day by day. There are no shortcuts to health; the only way is to take good care of yourself." To this end, drawing on numerous studies from home and abroad and consulting with several experts, we have summarized the 7 most common "aging-accelerating foods" in daily life.
1. Fried Foods
Such foods are high in calories and contain high levels of oil and oxidized substances. Frequent consumption can easily lead to obesity and is the most dangerous food for causing hyperlipidemia and coronary heart disease. During the frying process, a large number of carcinogenic substances are often produced. Studies have already shown that people who frequently eat fried foods have a much higher incidence of certain cancers than those who do not eat or rarely eat fried foods.
2. Pickled Foods
During the pickling process, a large amount of salt is required, which causes the sodium content in such foods to exceed standards, placing a heavier burden on the kidneys of those who frequently consume them. Furthermore, the high concentration of salt can severely damage the gastrointestinal mucosa, so those who often eat pickled foods have a higher incidence of gastrointestinal inflammation and ulcers. Most importantly, eating too many pickled foods can accelerate aging in women.
3. Canned Foods
Whether it's fruit or meat canned goods, most of their nutrients are largely destroyed, especially various vitamins which are almost completely depleted. In addition, the protein in canned products often becomes denatured, greatly reducing its digestibility and absorption rate, and significantly diminishing its nutritional value. Moreover, many fruit canned goods contain high levels of sugar, which is consumed in a liquid form, greatly increasing the absorption rate of sugar. This can cause a sharp rise in blood sugar and加重 the burden on the pancreas shortly after consumption. At the same time, due to their high energy content, they are suspected of causing obesity.
4. Processed Meat Products
These foods contain a certain amount of nitrites, so they may have the potential risk of causing cancer. In addition, due to the addition of preservatives, colorings, and color fixatives, they place an extra burden on the human liver. Also, products like ham are mostly high-sodium foods, and excessive consumption can lead to high salt intake, causing blood pressure fluctuations and kidney damage.
5. Peroxides
This is a peroxide of unsaturated fatty acids. For example, cooking oil that has been used to fry fish, shrimp, meat, etc., will form peroxides if left for a long time; as will dried fish, cured meat, etc., that have been left in the sun for a long time.
Long-stored biscuits, pastries, fried dough twists, oils, etc., especially oils that are prone to a rancid smell, will produce peroxides after the oil becomes rancid. Researchers have found that once peroxides enter the human body, they can cause great damage to the body's acid systems and vitamins, and accelerate the aging process.
6. Limescale
After prolonged use, teapots or water containers can develop limescale. If not cleaned in time, drinking from them frequently can cause lesions in the digestive, nervous, urinary, blood-forming, and circulatory systems, leading to aging. This is because the limescale contains harmful metal elements such as cadmium, mercury, arsenic, and aluminum.
Scientists once conducted a chemical analysis of the limescale from a thermos flask that had been used for 98 days and found a high content of harmful metal elements: 0.034 mg of cadmium, 0.44 mg of mercury, 0.21 mg of arsenic, and 0.012 mg of aluminum. These harmful metal elements are extremely detrimental to human health.
7. High-Temperature Cooking Oil Fumes
Foreign research institutions, after comparative analysis, have pointed out that Chinese people like to cook with high-temperature cooking oil, with stove temperatures being about 50% higher than those in Western homes. Typically, under the catalysis of high heat, cooking oil releases smoke containing butadiene components. Long-term and heavy inhalation of this substance not only alters a person's genetic immune function but also increases the risk of lung cancer.
Research reports indicate that rapeseed oil has a greater carcinogenic risk than peanut oil because, at high temperatures, rapeseed oil releases 22 times more butadiene components than peanut oil. To avoid this hazard, when cooking, it is best not to heat the oil beyond its boiling point; using hot oil is preferable. This can prevent the health-damaging effects of smoke and soot and the formation of facial wrinkles.
