Have you ever wondered what you should be eating to optimize your health? Nutrition scientists have been arguing that the entire dietary pattern matters more than a handful of individual foods reputed to have near-magical powers. Fortunately, a recent study demonstrated that several different eating patterns can be beneficial as a diet to lower cholesterol.

The Best Diet to Lower Cholesterol and Prevent Heart Attacks:

Q. What is the best diet to lower cholesterol, lose weight and stay healthy?

A. A recent study concluded that you can adapt your diet to your personal tastes and traditions. However, you need to stick to an eating pattern that is healthy overall (JAMA Internal Medicine, online June 15, 2020). In general, you’ll want to eat more whole foods and cut way back on processed foods. 

Over three decades, the researchers collected an enormous amount of data from nearly 200,000 health care professionals. There were 165,794 women who participated in the Nurses’ Health Study and the Nurses’ Health Study II. In addition, 43,339 men participated in the Health Professionals Follow-up Study. The researchers collected diet and health information from these volunteers every few years over decades, up to 32 years.

Can You Follow a Diet to Lower Cholesterol?

Those who scored higher on any of four different diet scales were approximately 20 percent less likely to have heart attacks or strokes. What the Healthy Eating Index-2015, The Adapted Mediterranean Diet Score, the Healthy Plant-Based Diet Index and the Alternative Healthy Eating Index share is a focus on vegetables, whole grains, legumes and fruit. None of them have much room for processed foods, refined grains or sugary foods and beverages. They vary in certain details, however. For example, the Mediterranean Diet Score adds points for fish consumption, while the Health Plant-Based Diet Index subtracts them. 

A diet to lower cholesterol should be rich in fiber. Soluble fiber found in oats, barley and legumes, can help reduce total and LDL cholesterol (Nutrients, May 23, 2019). A British study compared the effects of a Mediterranean diet and a vegan diet in 24 healthy young volunteers (Nutrients, Dec. 3, 2018). After a month, the participants following the Mediterranean diet had better blood vessel function. Conversely, those on the vegan diet lost weight and lowered their cholesterol.
