The National Cancer Institute has published dietary guidelines for the public. They are geared to cancer prevention but also are consistent with the USDA/DHHS Dietary Guidelines for Americans. The NCI Dietary Guidelines are:
Reduce fat intake to 30 percent of calories or less.


Increase fiber to 20-30 grams/day with an upper limit of 35 grams.


Include a variety of fruits and vegetables in the daily diet.


Avoid obesity.


Consume alcoholic beverages in moderation, if at all.


Minimize consumption of salt-cured, salt-pickled, and smoked foods.
