Ⅰ.阅读理解
We all know eating ultra-processed foods—such as sauces，and frozen pizza—isn’t goodfor our health.Studies have found they can raise our risk of obesity，heart problems，diabetes and
cancer.They may even shorten our lives.Now，a new study has revealed eating more ultra-
processed foods may contribute to overall cognitive decline ， including the brain executive
functioning—the ability to process information and make decisions.
“While in need of further study，the new results are quite compelling and emphasize the
critical role for proper nutrition in preserving and promoting brain health and reducing risk for
brain diseases，” said Tanzi，professor at Harvard Medical School.“They are very high in
sugar，salt and fat，promoting systemic inflammation(发炎)，perhaps the most major threat to
healthy aging.Meanwhile，since they are convenient and quick，they also replace fiber foods
important for maintaining the health and balance of bacteria in your gut ， ” added
Tanzi，“which is particularly important for brain health and reducing risk of age-related brain
diseases like Alzheimer’s disease.”
The study followed over 10,000 Brazilians for 10 years.“In Brazil，ultra-processed foods
make up 25% to 30% of total calorie intake.We have McDonald’s and Burger King.It is not very
different from many other Western countries，” said coauthor Dr.Suemoto.Ultra-processed foods
are defined as “industrial formulations of food substances containing little or no whole foods and
typically include flavorings，colorings and other chemical additives”，according to the study.
“People consuming over 20% of daily calories from processed foods had a 28% faster
decline in global cognition and a 25% faster decline in executive functioning compared to people
who not，” said study co-author Natalia.Those in the study who ate the most ultra-processed
foods were “more likely to be younger，women，white，had higher education and incomes，
and were more likely to have never smoked，” the study found.
“People need to know they should cook more，” Suemoto said.“And it’s worth it
because you’re going to protect your heart and guard your brain，” she added.
