Plant-Based Diet: Forks Over Knives, A Healthy Choice?

Forks Over Knives is a documentary film that promotes a whole-food, plant-based diet. The film suggests that a plant-based diet can help prevent and treat chronic illnesses such as obesity, cardiovascular diseases, and cancer. The Forks Over Knives diet is centred on whole, unrefined, or minimally refined plant foods and excludes or minimises meat, dairy products, eggs, and highly refined foods such as bleached flour, refined sugar, and oil. The diet is based on five food categories: fruits, vegetables, tubers and starchy vegetables, whole grains, and legumes.

The health benefits of a plant-based diet

The plant-based diet has become increasingly popular in recent years, with many people adopting it for ethical, environmental, or health reasons. The Forks Over Knives diet is a plant-based diet that gained popularity from the 2011 documentary film of the same name. This diet focuses on whole, unrefined, or minimally refined plant foods while excluding or minimising meat, dairy, eggs, and highly refined foods.

Weight Management

One of the most appealing benefits of a plant-based diet is easy weight management. Research shows that people who follow a plant-based diet tend to be leaner and have an easier time losing weight and maintaining a healthy weight without counting calories. This is because whole plant-based foods tend to be low in calories and high in fibre, which helps you feel full and satisfied without exceeding your calorie needs.

Disease Prevention and Reversal

The Forks Over Knives diet is particularly effective in preventing, halting, and in some cases, even reversing chronic diseases. Scientific evidence strongly supports the link between a plant-based diet and a reduced risk of heart disease, Type 2 diabetes, and certain types of cancer. Additionally, plant-based diets have been linked to lower rates of arthritis, improved liver function, and healthier kidneys.

Improved Heart Health

A plant-based diet is extremely beneficial for cardiovascular health. By eliminating animal-based foods high in saturated fat and cholesterol, and highly processed foods high in salt, you can significantly lower your risk of heart disease. A 2021 review of 99 studies found that diets rich in whole and minimally processed plant-based foods were associated with a significantly lower risk of cardiovascular disease compared to diets high in meat and dairy.

Diabetes Management

Plant-based diets are also associated with significantly lower rates of Type 2 diabetes and improved outcomes for those already living with the condition. A 2018 report found that plant-based diets were more beneficial than the diets recommended by several diabetes associations, offering greater improvements in physical and emotional well-being for those with Type 2 diabetes. The high fibre content of plant-based diets helps regulate blood sugar and properly absorb nutrients, which is crucial for managing diabetes.

Environmental Benefits

In addition to the health benefits, a plant-based diet also has a positive impact on the environment. Raising animals for food is an inefficient use of resources, and it contributes to climate change through greenhouse gas emissions. By contrast, plant-based diets require less farmland and produce fewer emissions, making them a more sustainable and environmentally friendly option.

Cost Savings

Whole and minimally processed plant-based foods are not only healthy and sustainable but also affordable. Research shows that a plant-based diet can cut grocery bills by $750 per person per year. Stocking up on staples such as brown rice, potatoes, and dried beans allows you to create nutritious and satisfying meals at a lower cost.

Adopting a plant-based diet can be a powerful way to improve your health, boost your energy levels, prevent chronic diseases, and positively impact the environment. The Forks Over Knives diet provides a comprehensive framework for those interested in reaping the benefits of a plant-based lifestyle.

The environmental benefits of a plant-based diet

The Forks Over Knives diet is a vegan, plant-based diet that promotes whole, unrefined, or minimally refined plant foods while excluding meat, dairy, eggs, and highly refined foods. It is based on the idea that a diet centred on whole foods from plants can improve health, boost energy levels, and prevent chronic diseases.

A plant-based diet has numerous environmental benefits. Firstly, it reduces the environmental impact of food production. Animal agriculture is a major contributor to greenhouse gas emissions, and raising animals for food is an inefficient use of resources. By contrast, plant-based diets are associated with fewer climate-altering emissions. A 2018 analysis found that livestock provides only 18% of calories consumed globally but uses up 83% of farmland. In other words, eating plants directly is a much more efficient use of resources.

Secondly, a plant-based diet can help reduce waste. Growing crops to feed animals creates a significant amount of waste, whereas eating plants directly cuts out this extra step.

Thirdly, a plant-based diet can help protect biodiversity and conserve water resources. Animal agriculture is a major driver of deforestation and water usage, and it can contaminate water sources with manure and other pollutants. By reducing the demand for animal products, a plant-based diet can help alleviate these environmental pressures.

Finally, a plant-based diet can also have economic benefits. Whole and minimally processed plant-based foods tend to be more affordable than animal-based or highly processed foods. This can help reduce food costs and improve access to nutritious meals for individuals and families.

In conclusion, a plant-based diet has far-reaching environmental benefits. By reducing greenhouse gas emissions, waste, and pressure on land and water resources, a plant-based diet can help protect the environment and promote a more sustainable food system. Additionally, the economic benefits of plant-based diets can improve food security and accessibility.

The difference between a vegan diet and a plant-based diet

The terms "plant-based" and "vegan" are often used interchangeably, but there are some key differences between the two. Both diets are centred on plant foods, but there are nuances to how these terms are defined and used.

The term "plant-based" typically refers specifically to one's diet and indicates that a person eats plant foods either entirely or mostly. Some people who follow a plant-based diet may still consume certain animal products, such as meat, milk, eggs, or honey. The term "whole foods, plant-based" is used to describe a diet that consists mostly of whole plant foods that are raw or minimally processed and excludes oils and processed grains.

Being vegan goes beyond diet choices and encompasses a person's entire lifestyle. Veganism is generally defined as living in a way that avoids, as much as possible, consuming, using, or exploiting animals. In addition to excluding animal products from their diets, vegans typically avoid purchasing items that were made from or tested on animals, such as clothing, personal care products, and household goods. The term "vegan" was coined in 1944 by Donald Watson, an English animal rights advocate, to describe a person who avoids using animals for ethical reasons.

Yes, it is possible and common to follow both a plant-based and vegan lifestyle. Many people may start as vegan, avoiding animal products for ethical or environmental reasons, and then adopt a whole-food, plant-based diet for health reasons. Others may begin with a whole-food, plant-based diet and later decide to expand into veganism by aligning the rest of their lifestyle choices to avoid animal products.

The five food groups of a plant-based diet

A plant-based diet is a powerful way to improve your health, boost energy levels, and prevent chronic diseases. Forks Over Knives recommends a whole-food, plant-based diet, which is centred on whole, unrefined, or minimally refined plant foods and excludes or minimises meat, dairy products, eggs, and highly refined foods.

• Fruits: Any type of fruit, including apples, bananas, grapes, strawberries, citrus fruits, and more. Fruits are a great source of natural sugars, phytochemicals, vitamins, minerals, and fibre. They provide a slow and sustained release of glucose into the bloodstream and offer a range of health benefits.
• Vegetables: A variety of veggies such as peppers, corn, lettuce, spinach, kale, peas, and collards. Vegetables are packed with vitamins, minerals, phytochemicals, fibre, and antioxidants. They are nutrient-dense and low in energy, making them a great way to bulk up your meals.
• Tubers: Starchy root vegetables like potatoes, sweet potatoes, yams, and cassava. These provide complex carbohydrates that keep your blood sugar and energy levels stable.
• Whole grains: Grains, cereals, and starches in their whole form, such as quinoa, brown rice, whole wheat, oats, popcorn, and more. Whole grains are a great source of energy and provide fibre, minerals, vitamins, protein, and essential fatty acids.
• Legumes: Beans, lentils, pulses, and other legumes are excellent sources of plant-based protein, fibre, vitamins, and minerals. They have been shown to offer incredible health benefits, including the prevention and treatment of chronic diseases, regulation of blood sugar levels, and promotion of healthy gut bacteria.

In addition to these five food groups, a plant-based diet also includes nuts, seeds, avocados, tofu, tempeh, whole-grain flours and breads, and plant-based milks. These foods are recommended to be consumed in moderation due to their higher calorie density.

The history of the term plant-based

The term "plant-based" has been used to describe diets that are centred on plants and exclude or minimise animal products for thousands of years. However, the specific use of the term "plant-based" to describe these diets is thought to have originated with T. Colin Campbell, PhD, in the early 1980s.

Campbell was a member of a 13-member expert committee of the U.S. National Academy of Sciences (NAS) that wrote the first 'official' document on the relationship between diet, nutrition, and cancer. He was also a member of an NIH panel reviewing research grant applications in chemical carcinogenesis. In these roles, Campbell was tasked with articulating emerging information suggesting that nutrition played an important role in the development of human cancer.

At the time, vegetarian and vegan diets were widely considered "outside of normal science", and Campbell wanted to communicate his ideas in an "objective, scientifically valid way". He chose the term "plant-based" to describe the diet he was researching, which focused on consuming low-fat, high-fibre foods, such as vegetables, fruits, and whole grains. Campbell added the word "whole" to his "plant-based" nomenclature later to distinguish this diet from those that included processed foods and isolated nutrients.

The term "plant-based" has since become widely used to describe diets that centre on whole, unrefined, or minimally refined plant foods and exclude or minimise meat, dairy products, eggs, and highly refined foods. This way of eating has been associated with various health benefits, including weight management, disease prevention, and improved heart health.
