Effect of palm olein oil in a moderate-fat diet on low-density lipoprotein composition in non-human primates.

Cohort Study

Animal

2002

Scientists fed monkeys three different types of fat in their food for two years and found that all three fats — palm oil, lard, and sunflower oil — had the same effect on the 'bad cholesterol' particles. So, switching between these fats didn’t change the cholesterol profile.

Similar Assertions

When monkeys ate a high-fat diet, their bad cholesterol went up not because each particle got fuller of cholesterol, but because there were way more particles floating around in their blood.

When monkeys ate a lot of fat and cholesterol for just 6 weeks, their bad cholesterol levels went up, their good cholesterol didn't keep up, and their cholesterol particles didn't get bigger—just more numerous.
