I will introduce this subject by referring to two web sites, the first obviously advocate that grass fed beef is better for you than grain fed beef; the second has similar emphasis for chicken. Later I will refer to scientific experiments conducted in Australia that clearly concludes that Omega 3 rich chickens can only be achieved through feeding chickens fish.
Good Fats Vs. Bad Fats
Lisa Urquhart shows you which fats to try and which to ditch
The Good
Monounsaturated and polyunsaturated fats have been linked to higher ‘good’ cholesterol (HDL) and decreased ‘bad’ cholesterol (LDL). Research suggests that eating these kinds of fats in moderation can improve your blood glucose levels and reduce your risk of developing heart disease.
You can find them in plant oils – olive, sunflower, canola, rice bran – as well as in nuts, fish, seeds, avocados and soy. These types of fats are also a staple of the Mediterranean diet, which is considered to be one of the healthiest diets in the world.
