Cardiovascular Health and Metabolic Markers

Guidelines regarding cardiovascular health highlight the importance of reducing saturated fats as they are linked with increased risks of cardiovascular diseases. These oils are a better option than those high in saturated fats. 
However, there is a difference between them. Safflower oil is lower in saturated fats and richer in monounsaturated fats, which is a better option than sunflower oil. 
However, this doesn't mean that sunflower oil is a bad oil. Comparatively, safflower oil is a better option. 
This doesn't mean you should eat fried foods all day because the oils are low in saturated fats. We need to consider trans fats and overall calories. Multiple factors affect our cardiovascular and metabolic health; saturated fats are just a part of them (2)(3)(4).
