Heart disease is the major cause of death in the world.

In addition to lifestyle factors like exercising and not smoking, eating a healthy diet is one of the best ways to reduce your risk of heart disease. That's because inflammation, blood pressure, blood glucose levels, and cholesterol are impacted by what goes into your body.

High fiber, healthy fats, and antioxidants have been shown to help the heart. Conversely, high intakes of added sugar and processed meats are of risk to the cardiovascular health.

Heart health is a significant reason for practicing a healthful regimen. Some of today's diet plans claim to support heart health, but it's essential to conclude that one is supported by scientific evidence and can be adhered to long term.

Here are the 6 best diets for those attempting to avoid heart disease.

1.The Mediterranean diet

The Mediterranean diet corresponds to the traditional eating habits of people in Greece and Southern Italy from the 1960s.

In general, people tend to eat foods with whole, minimally processed foods, including whole grains, nuts, seeds, fruits, vegetables, legumes, fish, and extra virgin olive oil. Additionally, they consume moderate amounts of poultry, eggs, low fat dairy, and red wine.

It limits or eliminates added sugars, refined carbs, overly processed snacks, and red and processed meats.

Numerous studies have tied the Mediterranean diet to a decreased risk of cardiovascular disease, among other heart disease risk factors, such as high cholesterol and triglyceride levels, obesity, diabetes, and hypertension.

A single review of 11 studies found that following a Mediterranean diet decreased overall heart disease risk and mortality by 40%.

People in the US usually endorse this diet for the inherent health benefits it presents. Opponents criticized the diet for its cursory approach to plant foods, with critics asserting that the benefits of whole foods are nearly immeasurable.

For example, olive oil is rich in monounsaturated fatty acids and compounds that have strong antioxidant properties and have anti-inflammatory properties.

A review of 32 studies found that a higher intake of this form of oil — but not other monounsaturated fats — was tied to a lower risk of death from all causes, heart disease, and stroke.

Other factors, such as engaging in physical activity and eating less added sugars may also contribute to the diet's positive effects.

2.The DASH Diet

DASH stands for Dietary Approaches for the Management of High Blood Pressure and was created to help promote successful treatments for high blood pressure, or hypertension. In turn, it can decrease your risk of heart disease.

The Mediterranean diet doesn't restrict food choices like the DASH diet does.

Instead of making specific recommendations regarding what sort of food you should consume, this menu recommends various amounts of food groups depending on how many calories you need each day, emphasizing whole grains, fruits, fresh vegetables, low-fat dairy, and lean meat while limiting the amounts of red meat, processed grains, and added sugars you consume.

According to the FDA, medical professionals suggest limiting sodium intake to no more than 1 teaspoon of salt per day — and for a lower salt option, no more than 3/4 teaspoon of salt is sufficient.

Decreasing salt intake in those with high blood pressure has been found to be extremely beneficial to blood pressure, especially when combined with the DASH diet.

However, research indicates that this blood pressure effect appears less significant among people with physiological blood pressure levels.

The diet's focus on increasing fiber consumption, such as with whole grains and fruits and vegetables, as well as lowering the intake of sugar and saturated fats may also result in its heart-health effects.

Indeed, studies show that the DASH diet can help reduce heart disease risk factors, such as blood pressure, obesity, waist circumference, cholesterol levels, and insulin resistance.

A review of studies encompassing the DASH diet found a twenty-percent decrease in heart disease risk, 19 percent decrease in stroke risk, and 18 percent decrease in the risk of developing type 2 diabetes.

3.Vegan and vegetarian diets

Vegan and vegetarian eating habits stop a complete reliance on meat, including poultry, red meat, and fish.

Some vegetarians also include eggs and dairy products in their diets, while vegans strictly avoid all animal-derived products, including dairy products, eggs, bee pollen, honey, and gelatin.

These diets encourage fruits, vegetables, beans, lentils, soy products, whole grains, nuts, seeds, and plant-based oils and fats.

Plant-based dietary choices provide lucrative nutritional advantages to vegan and vegetarian diets. For one, these diets are usually very high in fiber, antioxidants, and anti-inflammatory compounds, all of which aid cardiovascular health.

Regularly consuming whole soy products like tofu is linked to heart health benefits. In a meta-analysis of 46 studies, soy protein intake was shown to be an extremely useful method to lower low-density lipoprotein (LDL) and total cholesterol levels.

Moreover, a meta-analysis comprising over 200,000 people demonstrated that a regular intake of tofu and isoflavones — antioxidants in soy — was linked with a moderately reduced risk of heart disease.

Several other studies have suggested that a vegetarian diet or a vegan diet can reduce heart disease risk factors such as high cholesterol, blood pressure, weight problems, and uncontrolled blood sugar levels.

Studies have confirmed that not only are those who adhere to vegan or vegetarian diets less prone to heart disease and premature death, but they also have a higher adherence to these practices to begin with.

Regardless of what kind of diet you choose, you must still be conscious of complete nutrients. Vegan and vegetarian diets with high sugar, refined grains, and heavily processed foods have poor health benefits; on the contrary, those that emphasize plant foods are healthier.

4.The Flexitarian Diet 

Food blog writer Dawn Blatner developed this dietary plan, which uses plant-focused foods in moderate amounts, encouraging a complete spectrum diet. You are encouraged to eat most of the protein you consume from them.

There's no customary rule for how much or how often you should eat animal products, so it is dependent upon your personal preferences.

Whole foods are recommended to eat, foods with minimal additives and sugar are suggested to avoid, and salt and other refined grains should be avoided or limited.

Conducting studies revealed a connection between increased adherence to plant-based diets and a reduced risk of heart disease.

Fruits, vegetables, whole grains, and legumes — which the diet encourages — have been tied to improvements in heart disease risk factors.

On a strict vegan or vegetarian diet, the Flexitarian Diet may be a more sensible choice for those who would enjoy the heart benefits of a plant-based diet without having to give up meat and other items.

5.The TLC diet 

The Therapeutic Lifestyle Choices (TLC) diet was created by the United States National Institute of Health (NIH) to prevent and reduce the likelihood of heart disease and stroke.

Cholesterol, blood pressure, and body fat levels are all things that can be monitored to promote optimal conditions on your cholesterol and weight.

·        At least half an hour of moderate-intensity exercise is needed each day.

·        Aimed at getting 25–35% of your daily calories from fat.

·        The limit on saturated fat is to establishing no more than 7% of your daily caloric intake as your goal.

·        Limiting one's cholesterol intake to no more than 200 mg per day.

·        Getting in 10 to 25 grams of soluble fiber a day.

·        At least 2 grams of phytosterols or stanols are processed by your body each day.

·        Only taking the proper amount of calories to maintain a healthy lifestyle.

A number of studies confirm that a higher carbohydrate intake decreases LDL cholesterol [the bad cholesterol]. Particularly, a study of 32 days in length performed in 36 adults revealed a decrease in LDL cholesterol by 11% upon adopting the TLC diet.

Eating soluble fiber is advised for the improvement of one's diet. Foods like oats, nuts, seeds, beans, lentils, and fruits and vegetables contain soluble fiber.

Intake of high dietary fiber has been shown to reduce heart disease risk, and soluble dietary fiber in particular has been shown to reduce total and LDL cholesterol.

TLC diet also suggests taking in plant stanols or sterols, which are naturally occurring compounds in fresh foods like meat, vegetables, fruits, grains, nuts, and seeds.

Research suggests that consuming 2 grams of plant sterols or stanols per day, as the dietary plan recommends, can aide in reducing LDL (bad) cholesterol by 8–10%.

A strength of the TLC diet is that it calls for individuals to engage in at least 30 minutes of moderate workout daily.

It really is valuable to follow through with physical activity, as research shows that exercise can enhance heart health and avoid illness. One review reports that physical inactivity may contribute to as much as six% of heart disease cases worldwide.

6. Low carb diets

Low carbohydrate diets not only limit your carb intake but are also typically higher in protein and/or fat than the typically Western diet. They limit foods like breads, grains, pasta, potatoes, and sugar-laden snacks and beverages.

Carbohydrates can be restricted, depending on the recommended diet, to ten to forty percent of the calories consumed.

Research shows that low carb diets may improve heart health, decreasing chances of developing heart disease, such as overweight, obesity, and high triglycerides and blood pressure levels, as well as raising HDL cholesterol.

One review reported a decreased ratio of LDL (bad) cholesterol to HDL (good) cholesterol among low carb eaters, implying that such diets can improve a tendency toward bad cholesterol levels.

It’s important to note that these findings are promising, but more research is necessary.

Also, not all low carb diets are necessarily healthy for the body. Several observational studies have revealed higher risk of heart disease and related death in individuals adhering to these diets.

Yet, previous research that considered diet quality found a correlation between low carb diets rich in plants and protein and fat with a lower risk of death from heart disease and all causes, whereas those high in animal products and fat, were found to be associated with an increased risk.

For this reason, eating well will be your main priority. In particular, low-fat diets should be high on plant-food fibers like vegetables and low in processed vegetable oils, avocado, nuts and seeds.

How to choose a heart-healthy diet

When planning a diet that is healthy for your heart, do your research on the nutritional quality of your food choices, the scientific evidence behind them, how easy they are to follow, and your ability to sustain the diet over a reasonable period of time.

While more research is needed on the role individual nutrients play regarding cardiovascular events, research indicates that diets rich in whole foods, especially plant-based ones, can lower the risk for heart disease.

Healthy foods often include a mix of various whole foods and slow-growing or refined alternatives. Most experts agree that it's the composition of fat, not the amount, which makes the biggest difference in regards to heart health.

A few types of monounsaturated and polyunsaturated fats may be good for heart health, while trans fats have been shown to increase bad cholesterol and bad cholesterol, decrease good cholesterol, and worsen inflammation.

Researchers are unsure about the causes of saturated fats, but the U.S. Department of Agriculture (USDA) recommends limiting consumption of those to no more than 10% of your daily calories.

The ideal method to prevent heart disease involves many factors associated with your lifestyle.

Before beginning on any diet, it’s a good idea to consult your physician to confirm it is the appropriate choice for you.
