here is what I found on google:
Eating is another antidote to cold, since the digestion process produces heat. Choose something hot. Cocoa and Jalapenos! Although the amount of actual heat ingested is small, hot foods and beverages give the nervous system a warmth signal that encourages blood flow to the extremities. Spicy foods will do this too.
* Skip the Bud, Bud! Alcohol is poor choice when you're chilled. Alcohol is dehydrating and may suppress shivering, the involuntary muscle contraction through which the body warms itself.
* No Smoking! Tobacco also constricts blood vessels and acts to cool the body.
* Meat to Heat! Eating foods high in iron such as red meats and green leafy vegetables can help keep you warm. The body needs iron to make the thyroid hormone which stimulates heat production.
