Angina is a symptom of underlying problems, usually coronary artery disease, and occurs when the heart gets insufficient blood and oxygen. It can be a warning sign of a heart attack. While angina can be managed with medications, a low-fat, meat-free diet is also an ideal way to partially control the underlying coronary artery disease. A whole-food plant-based diet has been shown to reverse angina symptoms without medications or procedures, and can be recommended for patients with atherosclerosis.

What You'll Learn
A whole-food plant-based diet can help reverse angina symptoms
Angina is chest pain or discomfort that most often occurs when you do certain activities or feel stressed. It is caused by poor blood flow through the blood vessels of the heart muscle. A whole-food plant-based diet can help reverse angina symptoms.
A 60-year-old man with typical angina and a positive stress test chose to adopt a whole-food plant-based diet, which consisted primarily of vegetables, fruits, whole grains, potatoes, beans, legumes, and nuts. He declined drug therapy and invasive testing. Within a few weeks of this lifestyle change, his symptoms improved rapidly, as did his weight, blood pressure, and cholesterol levels.
In another case, a 77-year-old woman with unstable angina adopted a whole-food plant-based diet, and her symptoms resolved without mechanical intervention. However, when she resumed her previous diet of chicken, fish, low-fat dairy, and other animal products, her angina symptoms returned within four to six weeks.
Plant-based diets have been associated with improved plasma lipids, diabetes control, coronary artery disease, and a reduction in mortality. They can also help improve weight, blood pressure, vascular function, and glycemic control in patients with type 2 diabetes mellitus.
A whole-food plant-based diet appears to be an effective lifestyle therapy for patients with atherosclerosis, and it should be among the first recommendations for this condition.

Lower cholesterol by reducing saturated fat intake
Angina is chest pain or discomfort that occurs when doing certain activities or feeling stressed. It is caused by poor blood flow through the blood vessels of the heart muscle. A plant-based diet has been shown to improve angina symptoms, while a Western diet has been linked to the return of angina.
To lower cholesterol by reducing saturated fat intake, it is important to understand the role of cholesterol and saturated fats in the body. Cholesterol is a waxy, fat-like substance found in all the cells of the body and is essential for their proper functioning. While the liver produces enough cholesterol to support bodily functions, dietary cholesterol is considered extra and unnecessary. Saturated fats, found primarily in meat and dairy products, contribute to elevated levels of LDL or "bad" cholesterol.
To reduce saturated fat intake, limit or avoid meat and dairy products high in saturated fats, such as beef, lamb, certain pork cuts, poultry with skin, butter, cream, and cheese from whole or 2% milk. Instead, opt for lean meats and unsaturated oils like canola, olive, and safflower oils. Plant-based foods, such as nuts, soy, and fiber, can help lower LDL cholesterol while providing essential nutrition.
Additionally, be mindful of hidden sources of saturated fat. Salad dressings, soups, and stews can contain significant amounts of saturated fat. Removing the skin from chicken and opting for low-fat or plant-based milk alternatives can also help reduce saturated fat intake. Aim for a balanced diet, ensuring no more than 25% to 35% of your daily calories come from total fat, with less than 7% from saturated fat.
It is worth noting that other lifestyle factors, such as exercise, alcohol consumption, and stress management, also play a role in managing cholesterol and angina. Consult with a healthcare professional to create a comprehensive plan that includes dietary changes and lifestyle modifications suitable for your specific needs and medical history.

Avoid meat, dairy, and other animal products
Angina is chest pain or discomfort that usually occurs when doing certain activities or feeling stressed. It is caused by poor blood flow through the blood vessels of the heart muscle. Atherosclerosis and its related cardiovascular disease are the most common causes of morbidity and mortality in the Western world. The roots of this disease may lie, in part, in dietary and lifestyle behaviours, indicating that modification of these behaviours may lead to profound improvements.
Indeed, a whole-food plant-based diet has been found to be effective in treating angina. A 60-year-old man with typical angina declined drug therapy and invasive testing and instead adopted a whole-food plant-based diet, which consisted primarily of vegetables, fruits, whole grains, potatoes, beans, legumes, and nuts. His symptoms improved rapidly, as did his weight, blood pressure, and cholesterol levels. Similarly, a 77-year-old woman with unstable angina saw her angina symptoms resolve without mechanical intervention while consuming a whole-food plant-based diet. Her symptoms returned within four to six weeks of resuming a Western diet that included chicken, fish, low-fat dairy, and other animal products multiple times a day.
The benefits of a plant-based diet are supported by several studies. The Lifestyle Heart Study randomised patients with coronary atherosclerotic heart disease to a low-fat vegetarian diet versus a standard diet and followed them for one year. Patients in the experimental group were found to have a regression of angiographically detected coronary atherosclerosis and a 91% reduction in the frequency of angina. Another study by Esselstyn et al. reported a similar regression of coronary atherosclerotic heart disease by angiography in patients who adhered to a whole-food plant-based diet. Additionally, a review by Ferdowsian and Barnard describes the beneficial effects of plant-based diets on plasma lipids, reporting an up to 35% decrease in plasma low-density lipoprotein (LDL) cholesterol with a whole-food plant-based diet combined with nuts, soy, and fibre.
Therefore, avoiding meat, dairy, and other animal products as part of a whole-food plant-based diet can be an effective way to treat angina and improve overall cardiovascular health. However, it is important to note that a plant-based diet may require substantial dietary changes, and it is always recommended to consult a healthcare professional before making any significant dietary modifications.

Increase fibre from whole grains
Angina is chest pain or discomfort that occurs when doing certain activities or feeling stressed. It is caused by poor blood flow through the blood vessels of the heart muscle. A plant-based diet has been shown to improve angina symptoms. In addition, increasing fibre intake from whole grains can have a positive impact on heart health and overall well-being.
Whole grains are recommended by the American Heart Association for maintaining heart health. They contain the entire grain, including bran, germ, and endosperm, whereas refined grains have been milled, removing the bran and germ, and thus stripping the grain of important nutrients such as B-vitamins, iron, and dietary fibre. Examples of refined grains include white and wheat flours, enriched breads, and white rice.
Whole grains are a good source of dietary fibre, which has multiple health benefits. Fibre can help improve blood cholesterol levels, lower the risk of heart disease, and reduce the chances of stroke, obesity, and type 2 diabetes. It also aids in weight loss by increasing satiety and reducing calorie intake. In addition to fibre, whole grains provide essential vitamins and minerals, including thiamin (Vitamin B1), riboflavin (Vitamin B2), niacin (Vitamin B3), folate (Vitamin B9), iron, magnesium, and selenium. These nutrients are crucial for various bodily functions, such as forming new cells, carrying oxygen in the blood, regulating the thyroid, and maintaining a healthy immune system.
When incorporating more fibre into your diet, it is important to choose whole foods over supplements. Examples of whole grains include wheat bran, high-fibre cereals, whole oats, barley, and oats, which are rich in beta-glucan, a type of soluble fibre. It is recommended to include a variety of whole grains in your diet, as they differ in their nutrient content.
In addition to dietary changes, managing angina may involve taking prescribed medications, limiting alcohol consumption, exercising regularly, and controlling blood pressure and blood sugar levels.

Exercise is a major lifestyle component to prevent coronary disease
Angina is chest pain or discomfort that usually occurs when doing certain activities or feeling stressed. It is caused by poor blood flow through the blood vessels of the heart muscle. A plant-based diet has been shown to improve angina symptoms. However, exercise is a major lifestyle component in preventing coronary disease.
A sedentary lifestyle is one of the five major risk factors for cardiovascular disease, along with high blood pressure, abnormal blood lipids, smoking, and obesity. Research has shown that reducing these risk factors decreases the chance of a heart attack or other cardiac events, such as strokes. It also reduces the possibility of needing coronary revascularization procedures, such as bypass surgery or coronary angioplasty.
Physical inactivity has a significant impact on health and the economy. In the United States, coronary heart disease is the leading cause of death, with over 700,000 deaths annually. Approximately 60% of Americans aged 18 and older are physically inactive, and physical inactivity is estimated to cost the nation billions of dollars in hospitalizations and other related healthcare costs.
Regular exercise has numerous benefits for cardiovascular health. It promotes weight reduction, helps to lower blood pressure, and improves the body's ability to control blood glucose levels. Exercise can also reduce "bad" cholesterol levels in the blood (low-density lipoprotein [LDL]) and raise "good" cholesterol (high-density lipoprotein [HDL]). These improvements in cholesterol levels can lead to a decrease in plasma low-density lipoprotein (LDL) cholesterol of up to 35%.
Healthcare professionals should encourage patients, including those with CVD, to engage in regular physical activity. Cardiac rehabilitation programs focus on physical and mental recovery and the prevention of recurrent cardiac events by targeting cardiovascular risk factors and promoting a healthy lifestyle. Exercise programs have been shown to reduce the death rate for heart attack patients by 20-25%.
