According to research that will be published in the January 2011 edition of the Journal of the American Dietetic Association, seniors between the ages of 70 to 79 who ate a diet rich in high-fat dairy products had the highest risk of death over a ten-year period.
However, seniors the same age who ate a healthy diet–one with high amounts of vegetables, fruit, whole grains, poultry, and fish–lived longer lives.
The researchers analyzed the diets of 2500 American adults and found that during the ten-year period, those who ate a diet rich in high fat dairy products had a 34 percent death rate. Those who ate a diet fairly high in sweets and desserts had a 32 percent death rate, while only 21 percent of the healthy diet category died during the decade-long study.
The researchers took into account a number of other factors, such as gender, age, race, education, physical activity, smoking, and total caloric intake as part of the study.
To people who already eat a healthy diet and notice the health improvements this type of diet affords, the outcome of this type of research may seem fairly obvious but positive outcomes with this type of research may help to support further research into other health benefits of healthy diet.
