If you’re feeling sluggish, less energetic, or just plain traditional, the problem may not be so much your age, but the way you eat.

Believe it or not, modern science has pinpointed a number of foods that make you feel old and tired, as well as soe foods that make you feel younger.

Old Food: Sugar And Simple Carbs

Sugar does give you a temporary jolt of energy, but because your body metabolizes sugar quickly, you’ll soon feel sluggish and tired.

So before you eat, check the label.

Is there a lot of sugar? Are the carbohydrates simple instead of complex? Then skip it!

Young Food: Eggs

Not only are eggs a great source of energy-giving proteins, but they contain the carotenoids lutein and zeaxanthin, considered essential to keeping your vision young and sharp. Keep your body young by having an omelet for breakfast, lunch, or dinner.
