This kind of diet will destroy men's physical health!

Men's diet is closely related to their physical health. Some foods are fatal to men, such as trans fatty acids. Many people are unfamiliar with this name, so today we will look at the harm that trans fatty acids can cause to men that cannot be ignored.

1. What are trans fatty acids?

Trans fatty acids, also known as hydrogenated fatty acids, are normal vegetable oils that have been hydrogenated. Their properties are similar to saturated fatty acids. In terms of chemical structure, trans fatty acids belong to unsaturated fatty acids. Natural oils are mainly composed of cis fatty acids. Cis unsaturated fatty acids are liquid at room temperature, while trans unsaturated fatty acids are solid at room temperature.

2. What are the hazards of trans fatty acids to men?

Frequent consumption of junk food can easily lead to male infertility. Researchers from Harvard University and the University of Murcia in the United States surveyed 188 men aged 18-22 and found that those who frequently consumed trans fatty acids had a higher risk of infertility. Before participating in this study, these men had no other health factors that affect sperm quality, and their diets were divided into two categories: "Western" diet - rich in red meat, refined carbohydrates, sweets and energy drinks; "wise" diet - rich in fish, fruits, vegetables and whole grains. Researchers found that "wise" eaters had stronger sperm motility, while those men with poor diets were less likely to have sperm that survived the process of fertilizing the egg.

"Our work found that a healthy diet appears to benefit semen quality by improving sperm motility, meaning more sperm are moving around rather than just sitting still," said Audrey Gaskins, lead author of the study, which was presented recently at the annual meeting of the American Society for Reproductive Medicine.

Research led by Dr. Jörg Schavano of the Harvard School of Public Health showed that a diet high in trans fatty acids led to a decrease in sperm concentration, and the levels of trans fatty acids found in sperm and semen also increased. Gaskins stressed that despite the above results, more scientific research is still needed to study the exact relationship between nutrition and infertility. Edward King, president of the American Society of Male Reproduction and Urology, said: "We are still studying the impact of nutrition on male fertility, but even the initial research shows that a better diet is positively related to male reproductive health."

3. What trans fatty acid foods are there in our daily life?

1. Overheating cooking oil will turn fat into trans fat. There are three main sources: 1. Hydrogenated vegetable oil. When vegetable oil is hydrogenated, some unsaturated fatty acids will undergo a configuration change, from the natural cis structure to the trans structure, which can be made into margarine or artificial butter, in which the content of trans fatty acids can reach 50%. Using hydrogenated vegetable oil in food can improve the taste of food and extend the shelf life of food.

2. Meat and milk from transfatty animals such as cattle and sheep. The content of trans fatty acids in the body fat of transfatty animals accounts for 4% to 11% of the total fatty acids, and the content in cow's milk and goat's milk accounts for 3% to 5% of the total fatty acids. This natural trans fatty acid cannot be compared with artificially synthesized trans fatty acids.

3. Excessively high oil temperatures will produce trans fatty acids. When refined oils and cooking oil temperatures are too high, some cis fatty acids will turn into trans fatty acids. Although the increase is not obvious, you should try to avoid overly high oil temperatures when cooking.

4. McDonald's, KFC and other fast food chains have been questioned and complained about trans fatty acids, and the media has reported on this many times. In fact, trans fatty acids are not only found in fast food. If you pay attention to food labels when shopping in the supermarket, you will find that many snacks and other foods contain trans fatty acids.

4. What are the aliases of trans fatty acids?

1. There are almost no foods sold that have the words "trans fatty acids" directly on them. If a food has the following ingredients, especially hydrogenated vegetable oil, it usually contains a certain amount of trans fatty acids.

2. Ingredients often listed on labels include: hydrogenated vegetable oil, partially hydrogenated vegetable oil, hydrogenated fat, partially hydrogenated fat, vegetable shortening, shortening, margarine, artificial butter, artificial cream, non-dairy creamer, etc.

3. When buying food, be sure to read the ingredients listed on the label. Common foods containing hydrogenated vegetable oil include: biscuits, butter bread, cream cake, puff pastry, egg yolk pie, crackers, shortbread, oil-filled instant noodles, donuts, salad dressing, French fries, fried chicken nuggets, fried milk, pumpkin pie, chocolate pie, coffee companion, etc.
