Health checks
Low in Cholesterol

ⓘ
Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
Source
No Trans Fats

ⓘ
Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Source
Low in Saturated Fats

ⓘ
Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Source
Low in Sugars

ⓘ
While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
