Plant-Based Diets: Why They're Trending And Here To Stay

Plant-based diets have become increasingly popular in recent years, with many people adopting this style of eating. A plant-based diet primarily consists of food made from plants, including fruits, vegetables, nuts, seeds, whole grains, and legumes. It is not the same as a vegetarian or vegan diet, as it allows for the consumption of poultry, beef, eggs, fish, and dairy products, but with a focus on plants as the main source of nutrients. This type of diet is considered to be nutrient-dense, providing essential vitamins, minerals, healthy fats, protein, and fibre. Research has shown that plant-based diets offer various health benefits, such as lowering the risk of certain diseases, maintaining a healthy weight, and improving overall health and well-being.

Plant-based diets can reduce the risk of cancer

Plant-based diets have become increasingly popular in recent years, and for good reason. One of the most significant benefits of adopting a plant-based diet is the potential to reduce the risk of cancer. Research has consistently proven that a plant-based diet can lower the chances of developing this deadly disease.

A plant-based diet is primarily focused on foods derived from plants, including fruits, vegetables, whole grains, legumes, nuts, and seeds. It does not necessarily mean giving up meat entirely but rather emphasises making plants the majority of your meals.

Cancer Prevention

The nutrients found in plant-based foods, such as vitamins, minerals, phytochemicals, and fibre, are key to reducing the risk of cancer. Phytochemicals are chemical compounds that protect the body from damage and interrupt processes that encourage cancer production. Fibre, on the other hand, helps to lower the risk of specific types of cancer, such as colorectal and breast cancer.

Specific Examples

The University of Michigan Rogel Cancer Center highlights the benefits of dietary fibre. They found that eating 6 ounces of whole grain foods daily may decrease colorectal cancer risk by 21%. Additionally, a study by the Mayo Clinic Health System revealed that young women who consumed the most fibre-rich diets had a 25% lower likelihood of developing breast cancer later in life.

Plant-Based Diets and Overall Health

Plant-based diets not only reduce the risk of cancer but also promote overall health. They help maintain a healthy weight, which is crucial in cancer prevention, as excess weight can cause inflammation and hormonal imbalance, increasing the risk of certain cancers. Plant-based diets are also linked to improved gut health, allowing for better absorption of nutrients that support the immune system and reduce inflammation.

In conclusion, the popularity of plant-based diets can be attributed in part to their potential to reduce the risk of cancer. By incorporating more plant-based foods into our diets, we can take a proactive approach to our health and well-being while also enjoying the delicious flavours and variety that plant-based meals have to offer.

They can help maintain a healthy weight

A plant-based diet can help maintain a healthy weight. Research has shown that vegetarian populations have lower rates of obesity. A plant-based diet can help with weight management and can be recommended as a nutrient-dense option without compromising on diet quality.

A plant-based diet can help with weight loss without the need to count calories or restrict food intake. A study found that 65 overweight adults who followed a whole-food, plant-based diet for one year lost 9.25 pounds on average, without restricting calories. This is because whole grains and vegetables are relatively low on the glycemic index, meaning they are digested more slowly, and fruits contain antioxidants and fibre, which helps prolong fullness.

A plant-based diet can also help with weight management. Vegetarians are slimmer than their meat-eating counterparts, and vegetarian diets are nutrient-dense and can be recommended for weight management without compromising diet quality. A plant-based diet can also help reduce body mass index (BMI). A study found that the mean BMI for vegans was 23.6, while for non-vegetarians, it was 28.8, which qualifies as overweight.

A plant-based diet can also help lower the risk of obesity. Research has shown a positive association between meat consumption and obesity. A study assessed changes in weight and BMI over a five-year period in meat-eating, fish-eating, vegetarian, and vegan men and women in the UK. It found that the mean annual weight gain was lowest among individuals who had changed to a diet containing fewer animal foods. The study also reported a significant difference in age-adjusted BMI, with meat-eaters having the highest BMI and vegans the lowest.

A plant-based diet can also help reduce the risk of weight-related health issues. A healthy weight is one of the most important things you can do to reduce your risk of cancer. Excess weight causes inflammation and hormonal imbalance, increasing the risk of 12 different types of cancer. A plant-based diet can also help lower blood pressure and the risk of heart disease, which are also associated with weight.

They are nutrient-dense and packed with fibre

A plant-based diet is considered nutrient-dense and packed with fibre, healthy fats, protein, vitamins, and minerals. Fibre is present in all unprocessed plant foods and is beneficial for gut health, nutrient absorption, and bowel management.

Plant-based diets are associated with a reduced risk of developing type 2 diabetes. A study found that eating a plant-based diet filled with high-quality plant foods reduced the risk of developing type 2 diabetes by 34%. Plants are lower in saturated fats than animal foods, which can raise cholesterol levels and increase the risk of developing type 2 diabetes. Plant-based diets can also help with weight management, as they are often higher in fibre and lower on the glycemic index, leading to slower digestion and prolonged fullness.

Plant-based diets are also beneficial for heart health. Meat contains saturated fat, which can contribute to heart issues when consumed in excess. By cutting back on meat and increasing plant-based foods, you can lower your risk of heart disease. A study published in the Journal of the American Heart Association found that a plant-based diet may reduce the risk of developing cardiovascular disease by 16% and the risk of dying from this condition by about 31%. Plant-based diets are also associated with lower cholesterol levels, which is beneficial for heart health.

In addition to these specific benefits, plant-based diets have also been linked to a reduced risk of cancer, improved cholesterol levels, and a decreased risk of stroke. The high nutrient content of plant-based diets, including fibre, vitamins, minerals, and phytochemicals, contributes to their health benefits and makes them a very healthy way of eating.

Plant-based diets can help lower blood pressure

The Science Behind It

According to a meta-analysis of 39 studies, a plant-based diet is linked to lower blood pressure readings when compared to diets based on animal products. The DASH diet, for instance, is a plant-based diet that has been proven to reduce blood pressure, especially in African Americans and hypertensive subjects.

The Mediterranean Diet

The Mediterranean diet, which is largely plant-based, has been shown to reduce the risk of heart disease, metabolic syndrome, diabetes, certain cancers, depression, and frailty in older adults. It also leads to better mental and physical function.

The Vegetarian Diet

Vegetarian diets have been linked to a lower risk of developing coronary heart disease, high blood pressure, and diabetes. They also promote longevity.

The Vegan Diet

Vegan diets have been shown to lower systolic and diastolic blood pressure and reduce the risk of hypertension.

The Flexitarian Diet

A flexitarian diet, which is mostly plant-based but includes some animal products, has been shown to lower blood pressure and reduce the risk of hypertension.

The Whole Food, Plant-Based Diet

A whole food, plant-based diet focuses on unprocessed plant foods and has been linked to lower blood pressure and improved health.

The Link Between Plant-Based Diets and Lower Blood Pressure

Plant-based diets are rich in nutrients like vitamin C, potassium, and polyphenols, which have been linked to lower blood pressure and improved cardiovascular health.

The Bottom Line

Plant-based diets have been consistently proven to reduce the risk of cancer, heart disease, stroke, diabetes, and high blood pressure. They provide all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health and are often higher in fiber and phytonutrients.

By incorporating more plant-based foods into your diet, you can lower your blood pressure and improve your overall health.

They can help prevent type 2 diabetes

Plant-based diets are associated with a reduced risk of developing type 2 diabetes. They can also be used to treat type 2 diabetes, improving glycemic control, body weight, and cardiovascular risk factors.

How Plant-Based Diets Prevent Type 2 Diabetes

Observational studies have shown that people who eat plant-based diets have a lower prevalence of type 2 diabetes compared to those who eat meat. The Adventist Health Study-2, which included 61,000 participants, found that the prevalence of type 2 diabetes was 7.6% among non-vegetarians, 6.1% among semi-vegetarians, 4.8% among pesco-vegetarians, 3.2% among lacto-ovo vegetarians, and 2.9% among vegans.

The reason for this reduced risk is likely due to the fact that plant-based diets are lower in saturated fats than animal-based diets, which raises cholesterol levels and increases the risk of developing type 2 diabetes. Plant-based diets are also associated with lower body mass indices, which protects against type 2 diabetes.

How Plant-Based Diets Treat Type 2 Diabetes

Plant-based diets can be used to treat type 2 diabetes by improving glycemic control, body weight, and cardiovascular risk factors. A study published in the Journal of the American Heart Association found that a plant-based diet may reduce the risk of developing cardiovascular disease by 16% and the risk of dying from cardiovascular disease by about 31%.

A plant-based diet can also help with weight loss. A small study found that 65 overweight adults who followed a whole-food, plant-based diet for one year lost an average of 9.25 pounds, even without restricting calories.

In addition, plant-based diets are high in fiber, which can help improve glycemic control. A review of nine studies found that eating an extra 100 grams of fruits and vegetables per day led to a 13% reduction in the risk of cognitive impairment and dementia.

Mechanisms by Which Plant-Based Diets Address Type 2 Diabetes

Plant-based diets address type 2 diabetes by improving insulin sensitivity and beta-cell function, and by reducing inflammation and intracellular lipids. Plant-based diets are also associated with lower body weight, which is a major risk factor for type 2 diabetes.

Plant-based diets are typically lower in fat and higher in fiber than animal-based diets, which can help reduce the accumulation of intracellular lipids that interfere with glucose uptake and insulin production. Plant-based diets are also associated with lower levels of heme iron, a pro-oxidant that can promote insulin resistance.

Plant-Based Diets vs. Other Dietary Approaches for Type 2 Diabetes

Plant-based diets have been shown to be more effective than other dietary approaches, such as low-carbohydrate diets, in treating type 2 diabetes. A 2021 metabolic-ward study found that a low-fat, vegan diet led to a much greater drop in calorie intake than a low-carbohydrate diet. Plant-based diets have also been found to be more effective than Mediterranean and DASH diets in improving glycemic control and reducing weight and cardiovascular risk factors.
