The typical Western diet is the number-one cause of premature death and the number-one cause of disability. In other words, a long and healthy life is largely a matter of choice.

In this quote, Michael Greger underscores the harmful effects of the typical Western diet, which is often high in processed foods, sugars, saturated fats, and animal products. Greger asserts that this diet is the number-one cause of both premature death and disability, meaning that many of the leading causes of death and chronic illnesses in the Western world are directly related to dietary choices. This includes conditions like heart disease, type 2 diabetes, and certain cancers, which are all influenced by unhealthy eating habits.

Greger's statement emphasizes that a long and healthy life is not solely determined by genetics or fate, but is largely a matter of choice—specifically, the choices we make about what we eat. He suggests that by making healthier dietary decisions, such as adopting a plant-based diet or reducing intake of harmful substances, we can significantly improve our chances of living a longer, more vibrant life. The idea is that individuals have control over their health outcomes by choosing a lifestyle that supports their well-being.

The origin of the quote is rooted in the growing body of research that links dietary habits to health outcomes. Studies have consistently shown that populations that follow diets rich in whole plant foods tend to have lower rates of chronic diseases and longer life expectancies. By pointing out that health is largely a matter of choice, Greger emphasizes the power of nutrition in determining our long-term health and quality of life.

Ultimately, Greger’s quote serves as a call to action, urging people to take responsibility for their health by making informed dietary choices. It highlights the idea that by altering our diets to include more whole foods, fruits, vegetables, and plant-based proteins, we can prevent many of the diseases that contribute to premature death and disability, ultimately improving the chances of living a long, healthy life.
