Saturated fats found mainly in meat and dairy products have garnered a bad reputation in the health industry for quite some time. A new analysis of published studies finds no clear connection between people’s intake of saturated fat and their risk of developing heart disease.

Research has previously shown that saturated fat can raise blood levels of “bad” LDL cholesterol, and this is a major risk factor for heart disease and stroke. Because of this relationship, experts have generally advised people to limit their intake of fatty meat, butter, and full-fat dairy.

In the new analysis, which combined the results of 21 previous studies, researchers found no clear evidence that higher saturated fat intakes led to higher risks of hear disease or stroke. These findings, published in the American Journal of Clinical Nutrition, may sound like good news for steak and dairy lovers, but a past American Heart Association president cautioned against “over interpreting” the results. These new analyses are not going to change recommendations to keep saturated fat intake in check.

Perhaps the best take-away from the new interpretations is heart health is moving away from focusing on single nutrients and more toward “dietary patterns.” For example, a “Mediterranean” diet described as one rich in whole grains, fish, and unsaturated fats from vegetable oil, may help lower the risk of heart disease and stroke. Opposed to a so-called “Western” diet high in red and processed meats, saturated fats, and sweets would not be good in promoting heart health.

Having abnormal cholesterol levels can significantly increase your risk of heart attack or stroke. Abnormal levels of cholesterol are high levels of “bad” cholesterol (low-density lipoproteins), and/or low levels of “good” cholesterol (high-density lipoproteins). Taking control of your cholesterol can be done through exercising regularly and adhering to a low cholesterol diet.

One of the easiest ways to stick to a low cholesterol diet is to keep unhealthy foods out of your house. Simply grab a garbage bag, open the refrigerator and the pantry, and start tossing! Many of these unhealthy foods contain trans fats or saturated fats, and as of January 2006 the FDA ruled that all nutritional labels must include both saturated and trans fat content. The American Heart Association recommends that people get only 7% of their calories from saturated fat, and 1% from trans fat

Now start stocking up on heart-healthy oils and fats. Look for foods with polyunsaturated fats, found in nuts and seeds (also sunflower, peanut, and walnut oil) and monounsaturated fats, like olive, and canola oils, which are known to reduce the “bad” LDLs and increase “good” HDLs.

Several recent studies have shown that low vitamin D levels are tied to increased risk of heart attack and stroke. With statistics showing that three out of four Americans are not getting enough vitamin D in their diet, many people can benefit from taking this issue seriously.

One survey measured vitamin D levels from the same patients for up to 12 years. Compared to everyone in the study, the quarter with the lowest vitamin D levels had a 40% higher risk of dying from heart attacks, strokes, and other heart-related events.

The survey also delivered an additional variable that darker skinned people produce less vitamin D from sunlight than those with lighter skin tones; revealing that African-Americans are more likely than whites to die from heart attack, stroke, and other cardiovascular diseases.

In another recent study, conducted in order to examine the racial disparity in cardiovascular death, researchers analyzed data from a national health and nutrition survey that included more than 15,000 people; and found that African-Americans were 38% more likely to die from these heart-related events than non-Hispanic whites due to their lower vitamin D levels.

Vitamin D can be naturally produced by the human body with 10 to 15 minutes of direct sunlight exposure a few times a week; or it can be found in the following foods: butter, cheese, fortified milk and cereal, and margarine. The National Osteoporosis Foundation recommends that adults under 50 years old get 400 to 800 international units (IU) of vitamin D per day and that adults over the age of 50 get 800 to 1,000 IU. Darker skinned people may need even more.
