Eating Right After Age 30.

Regardless of the composition of patients diets up to the age of 30, if they improve their diets thereafter, they will reduce their risk of colorectal adenomas, Dr. Brian C. Chiu said at the annual meeting of the American Society of Preventive Oncology.

Few studies have examined the effects of dietary change during adulthood on adenoma risk, said Dr. Chiu of the University of Nebraska Medical Center in Omaha.

In his study, current dietary habits in subjects with a median age of 58 were compared with those the same subjects had had at age 30. Participants included 146 men and women who were found to have colorectal adenomas on sigmoidoscopy and 228 who did not have colorectal adenomas.

The data were adjusted for potentially confounding factors such as age, total energy intake, physical activity level, pack years of smoking, and NSAID use.

Subjects who showed the smallest reductions in red meat consumption during adulthood had an increased risk for colorectal adenomas, compared with those who had greatly reduced their consumption of red meat.

Similarly, subjects who had greatly increased their intake of poultry, fish, fruits, and vegetables had a significantly reduced risk of the neoplasms, compared with those who had not.
