Nutrition and Cardiovascular Risk

This week, a YouTube video has been making the rounds on Social Media. Dr. Salim Yusuf from McMaster University, who is also currently President of the World Heart Federation, presents data from the Prospective Urban Rural Epidemiology (PURE) study. This study includes data from 17 countries and over 150,000 people and contradicts the World Health Organization and the American Heart Association guidelines for nutrition and cardiovascular risk.

Here are a few take home points:

1) Red Meat in moderate quantities does not increase risk of cardiovascular events
2) White meat (chicken/fish) is likely moderately beneficial
3) Full fat dairy such as cheese is likely beneficial
4) No data to support reducing the fat content of milk
5) As saturated fat increases in the diet, LDL does go up; however, incidence
of cardiovascular events goes down
6) As carbohydrate increases, incidence of cardiovascular events goes up (risk of cardiovascular disease sharply increases when carbohydrate intake exceeds 40% of calories in the diet)
7) Optimal sodium intake is likely between 3 and 6 grams per day. Intake
below OR above that range results in increased incidence of cardiovascular events.
In the absence of hypertension, the upper limit is actually higher.
8) Fruits may be slightly beneficial and vegetables are more neutral – eating fruits
and vegetables does not significantly lower risk of cardiovascular disease.
9) Eggs are neutral and there is no limit.
10) Polyunsaturated fats, mainly from vegetable oils, did not show any benefit in reducing cardiovascular events.
