Make way salt and hypertension - you've got “competition.” Sugar, as it turns out, is just as much of a silent killer. A 2008 study found that excess fructose consumption was linked to an increase in a condition called leptin resistance. Leptin is a hormone that tells you when you've had enough food.
The problem is, we often ignore the signal our brain sends to us. For a growing number of people though the situation is even worse - leptin no longer produces the signal to alert us the body has enough food to function. This in turn can lead to over consumption of food and consequently, obesity.
So why is sugar - more precisely fructose - now one of the silent killers? Because over-consumption sets off no symptoms or warning bells. If you've gained weight in the past year and can't quite figure out why, you should definitely look at how much fructose you're feeding your body. Start with soft drinks and sweets, along with a good number of other grocery items, like jams, condiments and so on.
ALWAYS check the ingredient list - you'll find most of them contain corn syrup or, even worse, high fructose corn syrup!
