Back in the 70's and 80's some well meaning people came up with the theory
that the reason Americans were getting too fat was that they were eating too
much fat. Waistlines were expanding and heart disease was increasing. The
good folks in charge of making health policy recommendations decided that
eating fat made you fat. In short order, everyone got on board with what
appeared to be the obvious solution: stop eating fat.
Wrong.
Well, look. It's not like these experts got together and said, "Hey what can
we do to really screw up the health of America?" These were well meaning
people. They sincerely wanted to help us get on the right track. Taking a
page from current events, we might say that their hearts were in the right
place, but they had bad intelligence. Their information was just plain
wrong.
As Professor Harlan Onsrud put in Science Magazine, "Most of us would have
predicted that if we can get the population to change its fat intake. we
would see a reduction in weight. Instead," he added, "we have seen the exact
opposite."
Indeed we have. While the percentage of calories from fat in the American
diet has actually gone down over the last couple of decades, obesity has
gone up. And up. And up. And folks, its not because we're eating fat. Fat is
not the enemy, and cutting fat out of the diet is not the solution.
So we -- the experts -- were wrong about the cutting out fat. In fact, for
many people, particularly those who have type 2 diabetes or are at risk for
it, a low-fat diet can be nutritional suicide. Fat, of all the
macronutrients (the others being protein and carbs) has zero effect on
insulin, the fat storage hormone. Fat helps make you feel satiated. Many
fats -- omega-3's from fish, for example -- are anti-inflammatory. Some
saturated fats -- like those found in coconut oil -- are anti-viral. And
when you remove fat from the diet -- as in a high-carb, low-fat eating
plan -- you generally replace it with something else, usually carbs. Which
sends many people on a bumpy roller coaster ride of mood swings and blood
sugar dips, insulin spikes and increased fat storage. (The one exception --
where a high-carb diet might actually work -- is when the carbs eaten are
very, very high in fiber. That doesn't happen when you're eating processed
carbs like bread, pasta, and most cereals).
The death knell to the idea that fat was the enemy was sounded recently by
Professor Walt Willett of Harvard University, arguably the most prestigious
nutrition researcher of our time and lead author on both the Nurses Health
Study and the Health Professionals Follow-Up Study. In these studies,
Willett and his colleagues examined the eating habits of thousands of people
over two decades. Here's what he said: "We have found virtually no
relationship between the percentage of calories from fat and any important
health outcome."
In other words, fat doesn't make you fat. And, in my opinion, it also doesn'
t make you sick.
What does seem to matter, however, is the type of fat and the type of
carbohydrate eaten. Let's look at the carbs first. Processed carbs -- which
are most of the carbs that come in boxes and packages -- are seen by the
body as a big lump of sugar. They're deadly. And they drive triglycerides
through the roof. Carbs from vegetables and fruits -- and the ocassional
whole grain -- are loaded with fiber, which are associated with a king's
ransom of good health effects, including moderating blood sugar and insulin.
You can be on a low-carb or controlled-carb regimen and still consume a ton
of these good carbs. What you can't consume -- at least if you want to lose
weight -- is pasta, bread, baked goods and commercial cereals.
You can however, consume fat. And you should.
Now if you've read even a minimum of information about nutrition and diet
over the past few years, you're probably aware of the fact that there are
"good fats" and "bad fats." You've also probably heard that the bad fats are
saturated and the good fats are everything else.
Nope.
Bad fats are trans fats. Beginning in 2006 you'll see them listed on the
label of foods, but for now you have to be a detective to find them. Look on
the label for "hydrogenated oil" or "partially hydrogenated oil." If it's
there, put it back on the shelf and step away from the food. Trans fats are
associated with every degenerative disease you can think of. Bad fats are
also damaged fats. Fats can be damaged by high heat or chemical processing,
or by being used for frying multiple times (fast food chains are notorious
for this). And, contrary to popular opinion, omega-6 fats, which are a type
of polyunsaturated fat that everyone used to think was "healthy," are
actually quite pro-inflammatory and have been linked to increased risk of
cancer, particularly when they are not balanced in the diet with the
friendly omega-3's, omega-9's and saturates.
The best advice: get a nice mixture in your diet of saturated fats (coconut
oil, eggs, some meat), omega-3's (fish and flaxseed), and omega 9's
(macadamia nut oil, extra virgin olive oil). If your calories are what they
should be (more on this next month) and you're not eating more than you need
to keep your body healthy and in weight loss mode, the percentage of
calories from fat should be of no concern.
But the quality of your food should be.
And most of us who have eaten an "atkins" style diet know this to be fact! I now do not worry about fat or calories, but do watch the carbs and try not to go over 50 g/day... but the fat is the only way I can get the calories increased to 800+/day, which is when I lose the best Thanks so much for posting this!
