The aim of the study was to examine the associations of long-term high-fat dairy food consumption and conjugated linoleic acid (CLA) intake and the incidence of colorectal cancer. The study consisted of 60,708 women aged 40-76 years with over 14 years of follow-up.

The study found:
(a) Women who consumed 4 or more servings of high-fat dairy foods per day (including whole milk, full-fat cultured milk, cheese, cream, sour cream, and butter) had a 41% decreased risk of colorectal cancer when compared with the women who consumed less than 1 serving per day.
(b) Each increment of 2 servings of high-fat dairy foods per day corresponded to a 13% reduction in the risk of colorectal cancer.
(c) Women who consumed the most conjugated linoleic acid had a 29% reduction in the risk of colorectal cancer.

Conjugated linoleic acid can be found in animal based foods, including milk and meat. Different meats have higher levels of conjugated linoleic acid. Grass-fed cattle have a much higher amount of conjugated linoleic acid than grain-fed cattle. For this reason, grass-fed cattle and sheep may be the best source of conjugated linoleic acid.
