If you need to be social and sharp at a holiday gathering, have some eggnog...

There is one holiday treat that can actually improve your memory and social skills – eggnog! 

Sure, it’s packed with calories but the choline in eggnog will go straight to your head. Choline, a nutrient found in eggs, stimulates your brain cells and can improve memory and mental sharpness. Eggnog also has vitamins A, B-12, C and D, calcium, magnesium and potassium.

If you feel guilty about the three-to-four hundred calories you drank in that eggnog – you could always work it off. You’ll need to walk for 95 minutes, jog for 39 minutes or swim for a half hour – per glass.
