Plant-Based Diets: Longevity And Health Benefits

A plant-based diet has been linked to a longer and healthier life. Research has shown that eating more plants, fruits, vegetables, nuts, seeds, whole grains, beans and legumes can lead to a reduced risk of cardiovascular disease, type 2 diabetes, certain types of cancer, cognitive decline and obesity.

A study published in the BMC Medicine Journal found that a vegan diet can help decrease biological age and improve heart, hormone, liver, inflammatory and metabolic systems. Another study found that a 20-year-old who switches to a plant-based diet could add 10 years to their life, and even a partial change could add six years.

However, some plant-based diets may introduce vitamin and mineral deficiencies, and researchers have warned against large-scale recommendations of plant-based diets until more studies are completed.

A plant-based diet can reduce the risk of heart disease

Cardiovascular disease is the leading cause of death in the United States and worldwide. Eating habits play a crucial role in determining the risk of heart disease. A plant-based diet can be a powerful tool to prevent, manage, and even reverse heart disease.

Plant-based diets are typically low in dietary cholesterol and saturated fat, which are known to cause plaque buildup in the arteries, leading to heart disease. They are also rich in fiber, which has been linked to improved blood flow and a reduced risk of blocked arteries.

Multiple studies have supported the benefits of plant-based diets for heart health. One study found that a low-fat, plant-based diet combined with regular exercise and a healthy lifestyle can prevent, delay, and even reverse heart disease. Another study showed that a plant-based diet improved blood pressure, cholesterol levels, and reduced inflammation, all of which are risk factors for heart disease.

The quality of the plant-based diet is important. Consuming whole, unprocessed plant foods is associated with a lower risk of cardiovascular disease compared to unhealthy plant-based options, such as fried foods and processed foods, which are high in saturated fat.

Adopting a plant-based diet can be a gradual process. Small changes, such as having a meatless day or meal, can make a difference. It is also important to pay attention to food labels and choose minimally processed, whole food options.

In summary, a plant-based diet can be a powerful tool for reducing the risk of heart disease and improving overall health. By making gradual changes and choosing whole, unprocessed plant foods, individuals can lower their risk of cardiovascular disease and improve their quality of life.

It can also help lower cholesterol

A plant-based diet can help lower cholesterol and reduce the risk of heart disease. A 2017 meta-analysis found that plant-based diets, particularly vegetarian diets, were associated with lower overall cholesterol levels.

Supporting this, a smaller study from Stanford Medicine found that a four-week plant-based diet low in saturated fat and cholesterol led to lower LDL and total cholesterol levels in individuals. This was even more significant than a standard low-fat diet.

Another study found that a vegan diet improved the heart, hormone, liver, inflammatory and metabolic systems of 21 pairs of adult identical twins over eight weeks.

Plant-based diets are also associated with a reduced risk of metabolic disorders such as diabetes. A 2021 perspective in Advances in Nutrition found that a diet rich in whole grains, vegetables, fruits and legumes, while omitting or limiting animal products, is highly effective at treating type 2 diabetes and improving body weight and insulin sensitivity.

A separate study found that a diet high in animal protein led to a marked increase in diabetes, whereas no such elevation in risk was observed with proteins derived from plants.

In addition, a plant-based diet is also beneficial for cholesterol control and preventing certain types of cancer.

It may lower the risk of certain cancers

A plant-based diet may lower the risk of certain cancers. The National Cancer Institute (NCI) notes that individuals who eat a diet rich in plant foods have a lower risk of getting cancers of the mouth, pharynx, larynx, oesophagus, stomach and lungs. The NCI also states that there is evidence to suggest that maintaining a diet rich in plant foods lowers the risk of cancers of the colon, pancreas and prostate.

A study published in the BMC Medicine Journal found that those who ate a vegan diet showed a decrease in their biological age and also that of their heart, hormone, liver, inflammatory and metabolic systems. The study concluded that a vegan diet could lead to a longer life.

Research has also indicated that reducing consumption of animal-based products and increasing plant-based diets could lower the risk of cancer. A review of 48 studies found that vegetarian and vegan diets have a "robust statistical association" with better health on a range of risk factors linked to metabolic diseases, cancer and death.

Plant-based diets are considered better than animal-based foods when it comes to cancer prevention. The American Institute for Cancer Research promotes a plant-based diet.

It can aid in weight loss

A plant-based diet can aid in weight loss in several ways. Firstly, plant-based diets are typically rich in fibre, antioxidants, micronutrients, and beneficial plant compounds. These nutrients help increase satiety, improve digestion, and enhance overall metabolic health. This leads to reduced calorie intake and more efficient calorie burning, resulting in weight loss.

Secondly, plant-based diets tend to be lower in calories than diets that include animal products. This calorie deficit is crucial for weight loss, as it creates an energy imbalance where the body needs to tap into stored fat for energy, leading to a reduction in body fat. A study published in the BMC Medicine Journal found that those who followed a vegan diet consumed 200 fewer calories and lost two kilograms more, on average, than those on an omnivorous diet.

Additionally, plant-based diets are often associated with a reduced risk of metabolic disorders, including diabetes. The high fibre content of plant-based diets helps regulate blood sugar levels and improves insulin sensitivity, which are key factors in weight management. Stable blood sugar levels can reduce cravings and prevent the storage of excess glucose as fat, contributing to weight loss.

Furthermore, the exclusion of animal-based products, particularly processed meats and high-fat dairy, removes sources of unhealthy saturated fats and added sugars from the diet. These substances are linked to weight gain, especially when consumed in excess. By eliminating or reducing these foods, individuals can promote weight loss and improve their overall health.

Lastly, plant-based diets are often accompanied by an increased consumption of whole foods, such as fruits, vegetables, whole grains, beans, and nuts. These foods are generally more nutrient-dense and lower in calories than processed alternatives. The high nutrient content of whole foods helps the body function optimally, boosting metabolism and supporting weight loss.

It can help prevent type 2 diabetes

Plant-based diets are highly effective in preventing and treating type 2 diabetes. Type 2 diabetes is a global epidemic, with approximately 422 million cases worldwide and a rapidly rising prevalence in middle- and low-income countries. The prevalence of type 2 diabetes is rising in the United States and worldwide, posing a major public health concern. There is an urgent need to curb this rapidly rising incidence.

A plant-based diet is a cornerstone of healthy longevity and may be the most important prescriptive tool to help patients achieve a longer life and better quality of life as they age. Plant-based diets are eating patterns that emphasize legumes, whole grains, vegetables, fruits, nuts, and seeds and discourage most or all animal products. Plant-based diets are inversely associated with the risk of developing diabetes, independent of the positive association of meat consumption with diabetes development.

Plant-based diets can improve beta-cell function and insulin resistance. Beta-cell function (and mass) is inhibited by high-fat diets, which cause lipotoxicity, a phenomenon in which toxic fat metabolites accumulate in hepatic and skeletal muscle cells, impairing insulin signaling and thus decreasing glucose uptake. Plant-based diets are naturally low in fat and high in fiber, satisfying measures that improve glycemic control, insulin resistance, and beta-cell function. Plant-based diets also reduce the risk of chronic kidney disease, diabetic neuropathy, and diabetic retinopathy.

Plant-based diets are a safe and effective way to achieve serum glycemic control and insulin homeostasis. Plant-based diets promote weight loss, which is a primary surrogate of insulin resistance in most individuals. Plant-based diets not only improve insulin resistance but also improve the common modifiable cardiovascular risk factors, including serum lipids, serum glucose concentration, and systolic and diastolic blood pressure.

Plant-based diets are highly effective in the prevention and treatment of type 2 diabetes.
