Eggs are a good source of protein but the yolks are high in cholesterol; egg whites are cholesterol-free. A diet high in cholesterol may contribute to high blood cholesterol levels and increase your risk of heart disease. Experts recommend that you limit your cholesterol intake to less than 300 mg a day if you are a healthy individual and less than 200 mg a day if you have heart condition. Since one egg has about 213 mg of cholesterol, consider limiting other sources of cholesterol on days you eat eggs. The Mayoclinic offers tips to reduce cholesterol intake.

- Knee-toe: Tap right toe on the floor, jump to your left foot while lifting left knee up high, then switch.
