Shout It From The Rooftops: Sugar Does Not Cause Diabetes
dehydration is thirsty, because he hasn't been able to absorb water. Usually
this is because he hasn't found any water to drink, of course, but there are
other situations in which a person can become dehydrated no matter how much water
he drinks. Usually this stems from an underlying electrolyte imbalance of some
For example, if a
person drinks nothing but sea water, he'll become dehydrated because sea water
has too much salt in it. If you met someone who drank lots and lots of sea
water, you would observe him to be dehydrated. You might even tell him to stop
drinking sea water. But in the end, he'd need to drink some real fresh water in
order to cure his dehydration.
crave sugar, but that doesn't mean sugar causes
diabetes any more than water causes dehydration. The reason diabetics crave
sugar is because they are unable to absorb the sugar in their blood stream,
either because they don't produce enough insulin or because they are resistant
to the insulin they do produce. Whatever the underlying reason, however, the
point is that because a person is
diabetic, therefore they crave sugar.
Sugar doesn't cause diabetes; diabetes causes sugar cravings.
diabetes? For type 1 diabetics, the root cause is organ failure. For type 2
diabetics, the root cause is visceral fat.
There are many
people in the world who eat primarily high glycemic-index foods, but who never
become obese and never acquire lots of visceral fat: The rice farmers of
Vietnam, the mango farmers of Central America, the rural populations of
Morocco, and so on. No matter how much sugar they eat, they do not get type 2
diabetes because they never acquire a large amount of visceral fat. They do not
tend to have an obesity problem. Clearly it is not merely eating
high-carbohydrate, high-glycemic-load foods that causes type 2 diabetes,
contrary to the claims of Gary Taubes and his ilk.
As soon as a person
acquires a lot of visceral fat, however, their risk of diabetes skyrockets. It
may be a good idea to avoid high-glycemic-load foods if you have a weight
problem, because these foods tend to also be high in calories, and high-calorie
foods promote weight gain regardless of their glycemic load.
But it's important
to remember that the relationship looks like this: excess calories -->
weight gain --> visceral fat --> diabetes.
Feeding mice a
high-fat, high-calorie diet leads to this type of inflammation, as a result of
fat cells growing faster than the blood supply (a similar thing happens in
humans with type 2 diabetes). So the fat cells begin to die off, spilling out
their contents, which the immune system clean-up cells, the macrophages, come
along and mop up.
reaction causes havoc in the fatty tissue."
By studying the
reaction more closely, the researchers found it involves not only the
macrophages, but also the T cells and the B cells, which gradually inhibit the
ability of the remaining fat cells to respond to insulin, causing fatty acids
to seep into the blood.
