As someone with an insatiable sweet tooth, I was fascinated when I found out that hormones in our body affect how we perceive and crave sweetness. They do this according to our body's nutritional needs. Since I have a pretty bad sweet tooth, does this mean my body needs more of it? Not exactly. A recent article in The Economist explains that scientists have done the first step; they've isolated hormones that affect our palate's sensitivity to sugar.
The reason why this study is so important is because it may lead doctors and nutritionists to find a solution for ways of reducing the desire for sugar-heavy foods, and thus reduce calorie-intake. Yuzo Ninomiya, a neuroscientist at Kyushu University in Japan, researched the effects of leptin, a hormone that regulates appetite and metabolism. His results show that when leptin levels are low, we are more sensitive to sugar, which means something tastes sweeter than when our leptin levels are low. The level of the hormone increases over the day. This might explain why we tend to eat lots of sugar in the morning ('cause it tastes so good!).
So, it seems, if scientists can figure out how to raise leptin levels (or at least keep them steady) throughout the day, then all of us sweet-tooth types might have a chance at eating less cake!
In a world full of sweets, it's not easy to avoid them. What are some ways you control your sugar intake?

Ask the barista how much milk they go through in one day then next time you go into Starbucks for a latte. At some stores, the baristas probably far to busy to take note of the number of gallons used, but it is safe to say that it is a lot. And with over 5,500 stores in the US, Starbucks must be one of the largest consumers in the country, so the dairy industry will feel the effects of Starbucks decision to
Although many consumers are concerned with the standard of living of the cows, one of the primary reasons that people buy organic milk is because they are concerned about drinking milk from cows that have been treated with hormones, specifically the growth hormone rBST. The hormone has been in use since 1993 and estimates say that about 22% of cows are regularly treated with it. Only about 3% of the milk market is covered by organic milk and, due to demand and the higher operating costs of organic farms, organic milk can cost consumers twice as much as conventional milk.
No additives, no hormones. no chemicals... do these phrases mean what you think they mean?
