Eating junk food, such as fries, burgers, soft drinks etc. has always been associated with significant weight gain and other health issues, such as a high level of bad cholesterol. Now a team of scientists at Australian National University has found a direct link between eating more junk and a decline in brain health.
Today people consume an additional 650 calories every day, as compared to 50 years ago, i.e. in the 1970s, highlighted this research study published in Frontiers in Neuroendocrinology. This is a quarter of the recommended daily food energy needs for men and under a third for women. The results of the study also showed that nearly 30 percent of the world's adult population is obese or overweight, and by 2030 more than 10 percent of all adults will suffer from type 2 diabetes, which is already linked to brain deterioration.
Professor Nicolas Cherbuin, who led the research, said, “We’ve found strong evidence that people’s unhealthy eating habits and lack of exercise for sustained periods of time puts them at serious risk of developing type 2 diabetes and significant declines in brain function, such as dementia and brain shrinkage. People are eating away at their brain with a really bad fast-food diet and little-to-no exercise.”
He further said that this decline can be be much faster than people previously thought and can be attributed to a society that consistently promotes an unhealthy lifestyle. People with dementia or other signs of cognitive dysfunction, such as shrinking brains, have increased their risk by constantly eating bad food and skipping workout and the damage is irreversible once a person reaches midlife, he added, saying that people should eat healthy from a young age or at least from early adulthood.
