Milk chocolate has very little caffeine. Generally only dark chocolate has any appreciable amount of caffeine.

Nhs guidelines suggest a 50g bar of milk choc would have approximately 25mg. The amount of actual chocolate in a Mars bar is small so caffeine will be slight. Won't bring you anywhere near the 200mg recommended daily limit. A Mars bar will have almost no caffeine.

A mars bar is 58g total, milk chocolate makes up ~ 40%. So 23g of milk chocolate would be about 5mg of caffeine. To put that in perspective the average cup of coffee has 95mg of caffeine.

I drink raspberry tea that I bought for my daughter who is pregnant. It tastes great, and I certainly did not notice any caffeine from drinking it. It's highly recommended for pregnant women so I don't think it would have much caffeine. I looked on a website that usually has all foods listed, but I didn't find raspberry tea. Still, it's a cool link. http://www.nal.usda.gov/fnic/foodcomp/search/index.html I bought my tea online from the bulkherbstore: http://www.bulkherbstore.com/RRLC

Well, caffeine increases your heart rate. Which in turn, increases your metabolism.

That's the simple answer. Metabolism is the rate at which your body burns calories. The more caffeine you take, the faster your heart pumps, the more calories you'll burn. Don't drink too much though!
