Takeaway
Ischemic Heart disease, or heart disease caused by lack of blood flowing to the heart muscle tissue, represents the leading cause of death worldwide and accounted for almost 9 million deaths in 2019. With 16% of the world’s deaths attributed to heart disease, heart disease also signifies the fastest-growing cause of death — increasing by more than 2 million deaths since the year 2000.
Ischemic heart disease typically occurs by the narrowing of the coronary arteries that feed the heart due to plaques forming on the artery walls. Plaques mostly form from poorly controlled lipid and cholesterol levels circulating in the blood. A diet high in fat and animal protein mainly contributes to elevated lipid levels. A sedentary lifestyle, chronic inflammation, and lack of exercise also contribute to the development of heart disease.
Several types of heart disease can be caused by a variety of reasons. Most people can decrease their risk of developing heart disease by changing lifestyle habits for the better. Diet, exercise, and dietary supplements can all have a positive impact on your heart health.
‌‌ ‌‌Staples of a Heart-Healthy Diet
Many foods have heart health benefits that taste great too. Let’s take a look at a variety of fruits, vegetables, grains, meats,  nuts , and other foods that rank high on the heart-healthy list.
Heart-Healthy Fruits
Avocado – Since ischemic heart disease typically begins with a diet high in saturated fat,  avocado  offers a healthy fat alternative for those looking to start a heart-healthy diet. Full of monounsaturated fats linked to reduced low-density lipoprotein (LDL) cholesterol levels (or bad cholesterol) and decreased risk of heart disease, avocados remain ideal for a healthy heart diet. Rich in  potassium , this green, and oily fruit could help reduce blood pressure and risk for heart attack and stroke.
Berries – High in anthocyanins and other powerful antioxidants, berries help to protect against inflammation and oxidative stress that contribute to an eventual diagnosis of heart disease. Various studies show a reduction in “bad” LDL cholesterol and systolic blood pressure with regular consumption of berries. Studies also show that eating blueberries daily improves the function of cells in the blood vessel wall lining. This in turn could help to control blood clotting. 
Bananas – An ideal source of  magnesium  and  potassium , both minerals essential to heart health, bananas can help lower blood pressure, a significant risk factor for heart disease. Although most people do not get enough potassium in their diet, a diet rich in potassium lowers heart disease risk by up to 27%.
Heart-Healthy Vegetables
Leafy Green Vegetables – Full of vitamins and minerals, leafy green veggies like  greens ,  kale , spinach, and cabbage remain high in antioxidants, which protect the heart. Their high levels of nitrates and  vitamin K  help to reduce blood pressure, protect the arteries, and decrease arterial stiffness.
Garlic – Yes, garlic is technically a vegetable. A heart-healthy vegetable thanks to its high levels of allicin, a compound study shows it can help reduce blood pressure and cholesterol levels.  Garlic  also helps to inhibit platelet buildup, which can lead to blood clotting and stroke.
Heart-Healthy Grains
Whole Grains – Higher in fiber than refined grains, whole  grains  have been found to benefit heart health. Whole grains such as brown rice, oats, rye, quinoa, and whole wheat can reduce “bad” LDL cholesterol and risk for heart disease.
Heart-Healthy Meats
Salmon – High in  omega-3 , studies show eating salmon three times a week for eight weeks decreased diastolic blood pressure significantly. Studies also show eating salmon and other fatty fish like tuna, mackerel, and sardines lowers total cholesterol, fasting blood sugar, and systolic blood pressure.
Fish oil supplements  have also been shown to have heart-healthy benefits such as improved arterial function with reduced blood lipids and blood pressure.
Heart-Healthy Nuts and Seeds
Walnuts – Studies show eating  walnuts  can reduce “bad” LDL cholesterol, decrease inflammation, and lower blood pressure — thereby reducing the risk for heart disease.
Almonds – Full of fiber and monounsaturated fats,  almonds  offer a heart-healthy treat that can reduce cholesterol and belly fat — both factors that contribute to heart disease.
Hemp Seeds – High in the amino acid arginine,  hemp seeds  get associated with reduced inflammatory markers found in the blood — a contributing factor to heart disease.
Flaxseeds – Shown to reduce total cholesterol and “bad” LDL cholesterol levels, flaxseeds offer a great heart-healthy seed to add to salads,  nut butters , or cereals.  Flaxseeds  have also been shown to decrease blood pressure, a significant factor in heart disease.
Heart-Healthy Legumes
Soybeans – Rich in  isoflavones , soybeans may help lower cholesterol levels.  Edamame , an immature soybean, also offers a good source of  fiber  and  antioxidants  — both heart-healthy nutrients.
Pinto Beans – Fermented by your good gut bacteria, pinto  beans  reduce “bad” LDL cholesterol and blood triglycerides.
‌‌ ‌‌A Heart-Healthy Lifestyle
Along with incorporating heart-healthy foods, making meaningful lifestyle changes can boost heart health and reduce your risk of heart disease.
Diet
Replacing a meal with a  protein shake  can help reduce your consumption of dietary cholesterol while keeping your protein intake sufficient. Reducing dietary cholesterol can help lower your risk for coronary artery disease and eventually ischemic heart disease.
Exercise
A sedentary lifestyle contributes greatly to heart disease. Sitting represents “the new smoking,” and heart disease rates continue climbing. A cardio workout, or aerobic exercise, remains the best option for improving heart health. Examples of aerobic exercise include walking, running, swimming, jumping rope, tennis, and cycling.
Doctors recommend at least 150 minutes of moderate aerobic exercise each week. That breaks down to just 30 minutes of activity a day, a minimum of 5 days a week.
The key to strengthening your heart while exercising remains moving fast enough to raise your heart rate and breathing rate. To make sure that you don't overdo it, you should still be able to talk to someone while exercising.
Reduce Stress
Stress, “the silent killer,” contributes to heart disease around the globe. Long-term stress leads to high levels of cortisol circulating in the blood. Increased cortisol levels contribute to higher cholesterol, blood pressure, and blood sugar levels — all common risk factors for heart disease.
Stress also promotes the build-up of plaque on the arterial walls, a leading factor in heart disease diagnosis.
Stop Smoking
Studies have shown that smoking contributes to glucose intolerance and low levels of “good” high-density lipoprotein (HDL) cholesterol in the blood, both having negative impacts on heart health. Smoking has also been connected to cerebral vascular disease, as well as ischemic heart disease.
‌‌ ‌‌4 Supplements to Support Heart Health
Vitamin D
Research has identified vitamin D deficiency as a risk factor for heart attacks, peripheral artery disease, and congestive heart failure.  Vitamin D  deficiency remains common as people spend less time outdoors in the sun. When sunlight contacts the skin, vitamin D synthesis occurs.
Taking a vitamin D supplement may help reduce your risk of heart disease if deficient. Ask your doctor to check your levels before beginning a vitamin D supplement to avoid toxicity.
Coenzyme Q10
Better known as  CoQ10 , it has heart health benefits including reduced risk of repeat heart attack, improved outcomes for patients with congestive heart failure, and lower blood pressure.
CoQ10 also combats unwanted side effects of statins, medications that lower cholesterol levels, muscle pain, and weakness. Studies also show CoQ10 raises “good” HDL cholesterol levels, yet another heart health benefit.

Omega-3 Fatty Acids
Known for helping to reduce triglycerides, lowering blood pressure, and reducing blood clotting, omega 3 fats remain a sure bet for heart-healthy supplements.
Red Yeast Rice
High is monacolin K,  red yeast rice  offers a natural alternative to cholesterol-lowering statins like lovastatin. Monacolin K remains chemically identical to the active ingredient in lovastatin and can, therefore, cause the same side effects, including muscle aches and weakness.
Combining red yeast rice with CoQ10 can help decrease the potential side effects of red yeast rice.

‌‌ ‌‌Heart Health, the Big Picture
Starting a heart-healthy diet can be a rewarding journey towards better health and improved quality of life. Reaping the benefits of decreased heart disease risk and improved energy and stamina offer just a few motivating factors to make the heart-healthy switch.
Limiting sodium, added sugars, and saturated fats represent additional considerations when moving towards a heart-healthy diet. Both the  DASH  and  Mediterranean  diets offer good heart health benefits.
Getting regular aerobic exercise signifies another key component to living a heart-healthy life. Hiking, biking, skiing, and rowing offer great ways to increase heart and respiratory rates while having fun outdoors. Vitamin D synthesis and nitric oxide production encouraged by exposure to the sun while exercising outdoors also provide heart health benefits.
Start your heart-healthy diet while increasing aerobic exercise and incorporate heart-healthy supplements for a holistic approach to reducing your risk for heart disease.
