A new study has shown that adults over the age of 65 who are underweight or fluctuate by more than 5 per cent may be more likely to experience more rapid cognitive decline than others. The results of the research by a team from the Department of Nutritional Sciences at Pennsylvania State University were published in the journal Obesity.
"We examined 11 years of data on weight, BMI and waist circumference. Any way we looked at the data, the relationship was crystal clear — the more a person’s weight varied from year to year, the faster that person experienced cognitive decline," said Muzi Na, associate professor of nutritional sciences and senior author of the study.
