Experts aren’t sure why people are more likely to have a heart attack during the winter than any other time of year. But a new human clinical study conducted in Malaysia reveals we aren’t doing our hearts any favors by eating a high-carb diet. And while that high-carb diet was associated with increased heart disease risk factors, fat intake didn’t move the needle one way or the other.
One person not surprised by the study’s findings is Jonny Bowden, Ph.D., CNS. “I’ve been saying for years that fat has been wrongly demonized. If anything, it’s sugar – not fat – that’s causing us to go off the metabolic rails. In this study, low-carb diets performed considerably better than high-carb diets.”
The study found that healthy adults who ate higher proportions of carbohydrates (compared with the amount of proteins or fat they consumed) tended to develop several elevated risk factors for cardiovascular disease including high blood pressure and more plaque-promoting small LDL cholesterol particles. Higher proportions of dietary fat intake were not associated with elevating these risk factors.
Notes Bowden, “A hormone called insulin and a condition called insulin resistance are at the core of pre-diabetes, and are turning out to be early warning signs for heart disease. And the results of this study showed that insulin measures were considerably better when people at diets with a lower amount of carbs, and that was true regardless of the amount of fat consumed.”
What should be on your holiday table?
Bowden says even small steps may have a healthy impact on your heart health. He has three suggestions:
- Stop cooking with vegetable oils. “Vegetable oils such as corn oil and canola oil are very inflammatory. The type of fat most people in this study consumed was Malaysian palm oil, which is 50% saturated fat. This supports a number of studies over the last decade that have vindicated dietary fat – including saturated fats – as the primary culprit in heart disease and other chronic illnesses. Malaysian certified sustainable palm oil is now available online and at specialty markets. Palm oil is also rich in nutrients such as brain- and heart-health vitamin E tocotrienols.”
- Cut back on sugar. “Let’s be realistic. I know you’re probably not going to give up your favorite holiday pie or cookies. But be kind to your heart by restricting those goodies to just a few days during the holiday season. In addition, try to minimize the hidden sugars in your holiday meals by preparing dishes from scratch instead of from a package. Surprising sources of hidden sugars include canned soup, salad dressings and pasta sauces.
- Put the brakes on eating refined grains. “Toss the white flour and white rice in favor of whole grain versions.”
Making a few easy holiday food swaps may help you get in the habit of taking better care of your heart throughout the winter. It may also help you get a head start on your healthy new year’s resolutions.
