China confirms: pollution undermines fertility

Prolonged exposure to air pollution threatens to significantly increase the risk of infertility. The research was carried out in China, involving 18 thousand couples, as anticipated by the British newspaper Guardian, which revealed that those living in areas with a moderately high level of pollutants are subject to a 20% more negative impact on fertility.

The study showed how fine particles and other pollutants could be at the origin of inflammatory states in the organism of men and women, capable of damaging the production of eggs and spermatozoa. Qin Li, a researcher at Peking University's Center for Reproductive Medicine, said: "There are now numerous studies that have ascertained that air pollution is associated with various negative effects on pregnancy.

it comes from a large and generalized portion of the population, with results that we believe are therefore valid across the board."

Foods that make us age

Researchers from the University of Navarra, Pamplona and Madrid analyzed data which provided both saliva samples for DNA analysis and accurate records of what and how much food industrial hired on a daily basis.

Based on the consumption of ultra-processed foods, the authors of the study divided them into four 4 groups: low consumption group of ultra-processed food, the average consumption group-lower, the medium-high consumption group and finally the high consumption group.

There is a relationship between premature organic aging and the consumption of ultra-processed foods, those industrial products with a long list of ingredients, attractive and colorful, frozen or not, sweet or savory and increasingly used by those who do not want to, and often not he has time to devote himself to preparing meals.

According to a study presented at the European and International Congress on Obesity and published in the American Journal of Clinical Nutrition, those who consume more than 3 servings per day of super-processed food rich in sugars, salt, saturated fats, additives, dyes, preservatives etc, is twice as likely to have shorter telomeres.

As if to say that an excessively industrialized diet could age our cells faster. Unlike fresh and quality food, highly processed products - whose consumption is increasing around the world while that of fresh foods is decreasing are ready for consumption, have long expiration dates, sweet or salty which are generally very tasty, which also favors the repurchase.

In short, we are talking about convenient products: certainly convenient for those who produce them, and this is obvious. But also for those who buy them: although anything but in terms of health. Several studies published before this one we are talking about have already associated the consumption of UPF with important chronic diseases: hypertension, obesity, metabolic syndrome, depression, type 2 diabetes and different types of cancer.

The telomeres, specialized structures located at the ends of chromosomes and which represent a protection for the chromosome itself. Telomere length decreases with aging. Analyzing the chromosomes, the authors observed that the risk of having shorter telomeres increased significantly with the consumption of highly industrialized food.
