How do you know good food?

Put your knowledge here.

I know eggs. Your grocery store egg has a light yellow yoke and the white is runny. A "real" egg has a dark orange yolk that stands up in the pan and the whites are firm.

The diet of the laying hens can greatly affect the nutritional quality of the eggs. For instance, chicken eggs that are especially high in omega 3 fatty acids are produced by feeding laying hens a diet containing polyunsaturated fats and kelp meal. Pastured raised free-range hens which forage largely for their own food also tend to produce eggs with higher nutritional quality in having less cholesterol and fats while being several times higher in vitamins and omega 3 fatty acids than standard factory eggs [24] Focusing on the protein and crude fat content, a 2010 USDA study determined that there were no significant differences of these two macronutrients in consumer chicken eggs.[25]
