Eggs

Years ago, eggs were considered unhealthy because of the cholesterol they contained.

It turns out, though, that much of the cholesterol they contained was healthy HDL, as opposed to LDL which is the dangerous type.

Eggs are rich in protein, contain healthy fats, and contain nutrients such as choline, B vitamins, and minerals.

They are also free of carbs and sugars, meaning that they have a G.I score of 0.
