Recent Studies Reveal Powerful Heart Health Benefits

Recent Studies Reveal Powerful Heart Health BenefitsCertain diets, like the Mediterranean diet, have shown many benefits for heart health, cholesterol levels, and even weight management. Part of the Mediterranean diet focuses on replacing saturated fats with different types of vegetable oils or oils that contain unsaturated fats. One particular type of vegetable oil, linoleic acid, has been identified as being able to provide many different types of health benefits when utilized in your daily diet.

Data for a Different Kind of Oil

Linoleic acid is the main type of polyunsaturated omega-3 fatty acid found in many vegetables oils, nuts, and seeds. Recently, it was studied as part of a comprehensive review by Harvard Public Health School researchers. Compiling data from 13 published and unpublished cohort studies involving a total of 310,602 individuals, Harvard researchers noticed a connection between the use of linoleic acid and reductions in heart-related concerns.

Lead author, Maryam Farvid, a visiting scientist and Takemi fellow in the Department of Nutrition, explained at length why linoleic acid can be an important component of a daily diet.

"Replacing either saturated fat or carbohydrates with vegetable oils and seeing significant benefits indicates that reduction in saturated fat or carbohydrates is not the only reason for the beneficial effects of linoleic acid. Instead, linoleic acid itself plays a special role in support of heart health. Randomized clinical trials have shown that replacing saturated fat with linoleic acid reduces total and LDL cholesterol. There is also some evidence that linoleic acid improves insulin sensitivity and blood pressure."

Other studies done by the University of Maryland Medical Center (UMMC) found that women, specifically, can derive benefits from linoleic acid. Research found that women who consumed 1.5 grams of alpha-linoleic acid per day lowered their cardiac health risks by 46% compared to those who consumed less than 0.5 grams per day. Alpha-linoleic acid was also shown help to increase healthy HDL cholesterol levels, and decrease unhealthy LDL cholesterol and triglyceride levels.

Integrating Linoleic Acid Into Your Daily Diet

Various cooking oils—such as soybean, canola, sunflower, safflower, and corn oils—all contain linoleic acid and can replace creams, butters, lards, and other animal-based fats as your primary source of healthy fats that are crucial to supporting daily heart health. Soybean and canola oils contain the highest yield of linoleic acid. For a healthy snack, walnuts are also rich in this fatty acid. Linoleic acid can also be taken in supplement form in vegetable-based omega formulas containing flaxseed oil.

Prioritizing Heart Health

Heart health continues to be one of the top priorities in today’s society. While the focus on how to utilize fats for good health is still being researched, studies have shown that nature can provide a variety of nutritious fat substitutes from vegetable oils, nuts, and seeds. With the growing popularity of the Mediterranean diet, the prevalence of healthy oils like linoleic acid will play a crucial role in carrying good heart health into the future.
