Some people think that eating ultra processed foods (超加工食品) can make our lives easier. They love them so much: pizza, hot dogs, sausages, hamburgers, cookies, cakes, candies. But others people who like healthy and light food believe that these junk foods aren’t good for our health.   

The key problem with these foods is that they are usually very high in sugar, salt and fat, all these may be harmful to the body and brain. Studies have found they can make us fat, increase the risk of heart problems and cancer. They may even shorten our lives.

A new study has showed eating more ultra processed foods for more than 20% of your daily calorie (卡路里), your cognitive (认知) ability will go down, including the areas of the brain—the ability to deal with the information and make decisions.

In Brazil, ultra processed foods make up 25% to 30% of total calorie intake (摄入). They have McDonald’s, Burger King and they eat a lot of chocolate and white bread.

Fifty-eight percent of the calories consumed (消耗) by United States citizens (公民), 56.8% of the calories consumed by British citizens, and forty-eight percent of the calories consumed by Canadians come from ultra processed foods.

Those in the study who ate the most ultra processed foods were “more likely to be younger, women, White, had higher education and income, and were more likely to have never smoked, and less likely to be present alcohol consumers (酒精消费者).”

People need to know they should cook more and prepare their own food from the beginning. We say we don’t have time but it really doesn’t take that much time. And it’s worth it because you will protect your heart and protect your brain from Alzheimer’s disease (阿尔兹海默症). It’s important to remember this: Stop buying ultra processed foods.
