Q. I crave chocolate everyday. Is this normal or am I addicted to it?
A. Women’s health expert, Dr. Pamela Talley, says that chocolate cravings are driven by the change in balance of male and female hormones in our monthly cycle. That same flux can be the cause of periodic acne that some women experience. Chocolate and other food cravings are part of a larger serotonin issue which is why Prozac is often the treatment of choice for Premenstrual symptoms.
Roseanne Rust, a registered dietitian, suggests one reason that people might crave chocolate is that it has some amphetamine-like properties. “Also, the cannabinoid-like fatty acids mimic the effects of marijuana, producing euphoria”.
Five Hundred years ago, Spanish conquistadors called chocolate the “Food of the Gods”, when they first discovered it in South America. That kind of reverential attitude hasn't altered much over the centuries, we still love it. In 1996, Americans consumed 1,412,685 metric tonnes according to the International Office of Cocoa, Chocolate and Sugar Confectionery in Brussels Belgium (and they should know, they make the best chocolate in the world). The U.S. Chocolate Manufacturers Association says that each of us consumes 5.32 kilograms or about 12 pounds per year.
So when you need a little afternoon pick me up, you can now confidently turn to chocolate. But don’t forget even though cocoa powder itself is intrinsically low in calories, all the added ingredients that help make it so tasty are high in caloric content. However it is not the kind of fat that is related to a rise in cholesterol levels and may indeed be beneficial in lowering cholesterol levels. Before chocolate-phoria over takes you, one last point, applying cocoa butter to your skin can trigger acne. But eating it should’t contribute anything worse than feeling very, very good.

Q. I have a habit of cracking my knuckles. What makes that "popping" sound when they are cracked? My friend says it will make them bigger, is this true ?
A. It won’t make them bigger, but it could over time. When you crack your knuckles, you are actually pushing the joint either into or out of its normal position. In either case, when you do this, gas, mostly nitrogen, is displaced and escapes from the joint space. This displacement of gas causes the "popping" and "cracking" sound of knuckles, and a few other joints. Not all joint "popping" sounds are caused by escaping gases. In some joints, most notably the hip, the sound is made by ligaments moving over the bone.
On the other hand, escaping gas seems pretty innocuous, right? Wrong. Your friend wasn't too far off when she/he told you that cracking your knuckles would make them bigger. By cracking your knuckles, what you are doing is pushing the joint further than its range of motion would normally allow. This puts stress on the ligaments and tendons that hold the joint together and in place. Ligaments behave a little like rubber bands -- you can pull and stretch them a lot; but, eventually they won't return to their original shape and length.
After years of pushing your joint past its normal range of motion, it may become "hypermobile." If the joint is very mobile (as in the hand), the joint surfaces might wear out. If this happens, the body responds by laying down more bone. Although this sounds like the body healing itself, in reality, matters are made worse. Usually, the bone is not laid down smoothly and the joint surfaces become rough. So, spurring or sharp spots will develop in the bone of the joint in question. Eventually, you may have rough surfaces moving against each other, to which the body might respond by swelling, increasing the amount of fluid and blood in the area. In the end, you could have a joint ("arthro") that is inflamed ("-itis").
Of course, little research has been carried out in this area, so it's difficult to say with a high degree of certainty that knuckle and other joint cracking will lead to arthritis or other joint diseases. But it's fairly safe to say that repeatedly pushing a joint beyond its normal physical range is not a good thing to do. And years down the road, you could possibly end up with arthritis in your hands, not just big knuckles like your friend said! I still crack mine and I have arthritic hands... oh well.
