Vegan Diets: Clear Arteries Or Just A Fad?

Heart disease is the leading cause of death in the US, with coronary artery disease being the most common type. Clogged arteries can lead to a heart attack or stroke, so it's important to keep them clear. A vegan diet is associated with better cardiovascular health, and there is evidence that it can help to unclog arteries. This is because a vegan diet is typically rich in fibre and phytonutrients, which reduce inflammation and oxidative stress, and does not contain saturated fat, cholesterol, or heme iron, which are harmful to heart health. However, it is important to note that not all plant-based diets are healthy, and unwholesome plant foods should be avoided.

A vegan diet can reduce cholesterol levels

Research has shown that a vegan diet can lower total cholesterol and LDL-C levels by 29 mg/dL and 23 mg/dL, respectively, when compared to non-vegetarian diets. This is because plant foods contain no cholesterol, whereas meat, eggs, and dairy products are high in cholesterol and saturated fats, which can lead to a build-up of plaque in the arteries.

High cholesterol levels can cause atherosclerosis, the narrowing and stiffening of arteries due to plaque build-up. This condition can lead to serious medical issues, including heart attacks, strokes, and peripheral artery disease. By reducing cholesterol levels, a vegan diet can help prevent and even reverse these dangerous conditions.

It is important to note that not all plant-based diets are equally beneficial. Unwholesome plant foods, such as refined grains and sweets, can negatively impact heart health. A well-balanced vegan diet, rich in fruits, vegetables, whole grains, and healthy fats, is ideal for lowering cholesterol and improving overall cardiovascular health.

Vegan diets are rich in fibre and phytonutrients

A vegan diet is rich in fibre and phytonutrients, which have multiple health benefits. Fibre, for instance, helps to lower cholesterol levels and prevent constipation.

Vegan diets are typically high in fibre, with vegans consuming the most fibre out of all dietary groups. This is because vegan diets consist of whole plant-based foods, which are rich in fibre. For example, a typical day of vegan meals, such as baked oats for breakfast, pasta salad for lunch, a smoothie as a snack, and chilli for dinner, can provide over 50 grams of fibre.

However, it is important to note that while fibre is beneficial for most people, there are some cases where a low-fibre vegan diet may be preferable. For example, those with digestive issues such as Crohn's disease or irritable bowel syndrome (IBS) may benefit from a low-fibre diet. In these cases, it is important to work with a doctor to ensure that the diet is meeting the individual's specific needs.

The amount of fibre in a vegan diet can be adjusted by choosing different types of foods. For a low-fibre vegan diet, it is recommended to focus on more processed foods, as they have a lower fibre content. For example, white bread, white pasta, and white rice are lower in fibre than their whole grain counterparts. Additionally, well-cooked canned or fresh vegetables in small amounts can be included, such as lettuce, tomato sauce, and seedless tomatoes.

On the other hand, for those looking to increase their fibre intake, it is recommended to focus on whole grains, legumes, nuts, and seeds, which are great high-fibre choices. Higher-fibre vegetables include broccoli, spinach, and carrots, while higher-fibre fruits include berries, pears, and stone fruits such as plums, peaches, nectarines, and apricots.

It is worth noting that while a vegan diet can provide many health benefits due to its fibre and phytonutrient content, it is important to ensure that all nutritional needs are being met. For example, vitamin B12 is a crucial supplement for vegans, as it is primarily found in animal products.

Overall, a vegan diet can be a great way to increase fibre and phytonutrient intake, but it is important to tailor the diet to individual needs and ensure that all essential nutrients are being consumed.

Vegan diets are associated with better cardiovascular health

A vegan diet can also help to clear out clogged arteries. Clogged arteries are caused by a build-up of plaque, which is made up of several substances, including cholesterol. High cholesterol levels in the blood are usually the main cause of clogged arteries. A plant-based diet can lower high cholesterol levels, as it does not contain any cholesterol, whereas meat, eggs, and dairy products do. A vegan diet is also rich in dietary fibre, which helps to eliminate excess cholesterol from the body.

The Physicians Committee for Responsible Medicine found that a plant-based diet is associated with 29 mg/dL and 23 mg/dL lower total cholesterol and LDL-C levels, respectively, compared with non-vegetarian diets. They also found that a plant-based diet can fully or partially open blocked arteries in up to 91% of patients.

It is important to note that not all plant-based diets are equally beneficial. A study by researchers from the Harvard T.H. Chan School of Public Health and Brigham and Women's Hospital found that a plant-based diet consisting mostly of unhealthful plant-derived foods, such as refined grains, had a negative impact on heart health. Therefore, it is crucial to focus on consuming healthy plant-based foods, such as fruits, vegetables, and whole grains.

A vegan diet can prevent and reverse atherosclerosis

Research has shown that a plant-based diet can effectively prevent and treat atherosclerosis. A study by Dr. Dean Ornish demonstrated that a low-fat vegan diet, combined with moderate exercise, can reverse atherosclerosis without the need for drugs. Within a year, participants in the study showed a reduction in plaque, an improvement in chest pains, and lower cholesterol levels.

A vegan diet is beneficial for preventing and reversing atherosclerosis because it eliminates cholesterol-rich foods, such as meat, eggs, and dairy, and is rich in fiber, which helps eliminate excess cholesterol from the body. Additionally, plant-based diets are associated with lower total cholesterol and LDL-C levels, reducing the risk of hypertension and weight gain, which are also risk factors for atherosclerosis.

It is important to note that not all plant-based diets are equally beneficial. Unwholesome plant-based foods, such as refined grains and sweetened beverages, can have a negative impact on heart health. Therefore, a well-balanced vegan diet that includes a variety of healthful plant foods, such as fruits, vegetables, whole grains, nuts, and healthy fats like avocado and olive oil, is ideal for maintaining cardiovascular health and preventing and reversing atherosclerosis.

A vegan diet can reduce the risk of hypertension

A vegan diet can help lower blood pressure and reduce the risk of hypertension. Research has shown that a low-fat vegan diet is the best diet for lowering cholesterol levels. Plant-based foods contain no cholesterol, while meat, eggs, and dairy products contain large amounts of cholesterol and saturated fats, which can cause arteries to become hard and clogged.

The high fiber content of a vegan diet also helps eliminate excess cholesterol from the body. Additionally, a vegan diet can reduce blood viscosity and improve vasodilation, insulin sensitivity, and the body's antioxidant content and anti-inflammatory effects, all of which contribute to lower blood pressure.

Several studies have demonstrated the positive impact of a vegan diet on blood pressure and hypertension. The Adventist Health Study-2 found that vegans and lacto-ovo vegetarians had significantly lower systolic and diastolic blood pressure and a lower risk of hypertension compared to non-vegetarians. Another study showed that a vegan diet reduced systolic and diastolic blood pressure by 3.4 and 4.1 mmHg, respectively, compared to a Mediterranean diet.

In summary, a vegan diet can effectively reduce the risk of hypertension by lowering blood pressure through various mechanisms, including reduced cholesterol levels, improved vasodilation, and increased antioxidant content.
