It's true that diets with high added / refined sugar are unhealthy. But diets with lots of beef and dairy and low on vegetable fiber are also unhealthy. The link between dietary cholesterol and blood cholesterol is much weaker than previously hypothesized, that's true, but there's ample evidence of the superiority of a vegetable rich diet. The medical and scientific consensus is still that diets high in saturated fats - especially animal fats - as well as trans fats increase your risk of heart disease and high cholesterol. Other lifestyle risk factors are obesity, lack of exercise, smoking and diabetes.
