What is Diet

The health benefits of eating more plant-based foods and less meat are scientifically proven. This chapter examines the evidence in relation to common health and medical conditions, such as cardiovascular diseases, type 2 diabetes, cancers, mental health, and dementia. It also analyzes the issues related to gastrointestinal health and diet in light of the presence of fiber and other plant materials. Although the environmental benefits of a plant-based diet are well-established, there are some concerns about the ability of such food choices to supply essential nutrients to the human body, such as protein, iron, vitamin B12, and Omega 3 fatty acids. They are discussed within the framework of a healthy diet. Some of the disadvantages of diets rich on animal proteins, such as heme iron, are highlighted with a warning that the consumption of lab-grown meat may carry similar risks. A balanced plant-rich diet seems a better and easier choice.
