KRON 4 | Can Just One Fatty Meal Be All That Bad?

You vowed to eat a heart-healthy diet and have been pretty successful, but every once in a while you can’t resist splurging on a big fat juicy cheeseburger and a thick, creamy milk shake. So is that really all that bad? Find out if an occasional surge of fat in your diet is okay.

The ‘Shake and Cake’ Study

The Heart Research Institute in Australia performed the following “carrot cake and milkshake” test. This well-known research was published in the American College of Cardiology. The subjects were normal weight men and women, age 18 to 40, with no cardiovascular risk factors or established heart disease.

KRON4_Fat & Heart Attack1
Researchers compared the effects from eating polyunsaturated (safflower oil) and saturated fat (coconut oil).

Each participant consumed fat in the form of a slice of carrot cake and a milkshake.  They had to eat one gram of fat per kilogram of body weight (i.e., one gram of fat for every 2.2 pounds).

For example, a 200-lb person (91 kg) had to eat 91 grams of fat or the equivalent of eating all of the following at one meal:

  • Double 1/4 pounder with cheese (45 g total fat) = 700 cal.
  • Large order of French fries (24 total fat) = 510 cal.
  • Large vanilla milkshake (22 g total fat) = 800 cal.

Subjects in the study ate as much fat equivalent to a McDonald’s meal.

Coconut oil is 90% saturated fat and solid at room temperature.

DAY 2 (one month later): The subjects returned and ate another carrot cake and milkshake meal that contained the same amount of calories and fat except the type of fat used was different. Instead of polyunsaturated fat, the cake and shake contained COCONUT OIL which is 90% saturated fat. Saturated fats are typically solid at room temperature.

The Role of HDL (“Good Cholesterol”)

HDL cholesterol is “supposed” to be anti-inflammatory, that is, they suppress inflammatory molecules from multiplying. When arteries become inflamed:

  • Substances adhere to the artery wall.
  • Arterial plaques can rupture. A blood clot forms around the rupture blocking the artery, resulting in a possible heart attack.

Coconut Oil: Is It Healthy or Hype?

Not a day goes by that I’m not asked about the latest and greatest health benefits of coconut oil. Due to its “good” saturated fat, coconut oil is being promoted as a cure-all for heart disease, weight gain, high LDL (bad) cholesterol, and Alzheimer’s disease (to name just a few). But is coconut oil and its powerful medicinal properties all that it’s touted to be?

Saturated Fat

Coconut oil is a saturated fat. These types of fats are generally concentrated in animal products, but are also present in tropical plant-based oils. Saturated fats can increase your LDLs (“bad” cholesterol) and increase your risk of atherosclerotic plaques, coronary artery disease, and stroke. That fact alone should be enough to put coconut oil on the “No Go” list of any healthy eating plan.

The Skinny on Sat Fat

Saturated fats are stable fats, that is, they’re not as sensitive to heat and light like other oils. That’s why they are solid at room temperature, can withstand high cooking temperatures, and have a long shelf life. Here’s how coconut oil compares with the other artery busters.

  • Beef fat = 40% saturated fat
  • Lard = 40%
  • Butter = 64%
  • Coconut oil = 92%

It’s All In the Acid

Not all saturated fats are created equal. Oils are made up of different types of fatty acids and in different percentages which impact how they react in your body. For example, chocolate contains 60% saturated fat. Stearic acid is its most common saturated fat which is why chocolate raises your LDLs significantly less than butter.

On the other hand, coconut oil contains about 65% of its saturated fats from lauric acid. The lauric acid may be what’s responsible for raising your HDLs (“good” cholesterol). But… don’t run out and buy a gallon of it just yet unless you plan on rubbing it on your skin!    Continue reading “Coconut Oil: Is It Healthy or Hype?”
