“How Not to Die” by Dr. Michael Greger is a book that aims to provide readers with evidence-based guidance on how to prevent and reverse chronic diseases by adopting a plant-based diet and making other lifestyle changes. Published in 2015, the book has garnered significant attention and praise from those advocating for a plant-based lifestyle. However, it is important to maintain a critical mindset when evaluating the claims made in the book.
Dr. Greger, a physician and internationally recognized nutrition expert, presents a compelling argument for the health benefits of a plant-based diet. He explores the connection between diet and diseases such as heart disease, diabetes, and various cancers, citing scientific studies to support his claims. His evidence-based approach is commendable and serves to inform readers about the potential benefits of adopting a plant-based lifestyle.
While “How Not to Die” provides valuable information, it is essential to approach the material with a critical eye. Dr. Greger’s recommendations may appear one-sided, as he emphasizes the benefits of a plant-based diet while downplaying the role of other factors such as genetics and environmental influences. Additionally, some critics argue that the book overlooks the importance of balanced nutrition and the potential risks of a restrictive diet.
1. Asthma and Animal Foods
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty in breathing. While there are various factors that can trigger asthma symptoms, accumulating evidence suggests that consumption of animal foods may play a role in the development and worsening of asthma.
Animal foods, such as dairy products, eggs, and meat, have been associated with increased inflammation in the body. This inflammation can affect the airways and worsen asthma symptoms. For example, dairy products have been found to increase mucus production, which can lead to further narrowing of the airways and difficulty in breathing.
In addition to inflammation, animal foods may also contribute to asthma through their effects on the immune system. Animal proteins have been shown to stimulate an immune response that can lead to increased production of antibodies and immune cells associated with asthma. This immune response can further exacerbate asthma symptoms and make them more severe.
Furthermore, animal foods may also contain allergens that can trigger asthma attacks in susceptible individuals. For example, eggs and dairy products contain proteins that are known allergens and can cause allergic reactions in some people, including asthma symptoms.
Overall, the evidence suggests that consumption of animal foods, particularly dairy products, eggs, and meat, may contribute to the development and worsening of asthma symptoms. Limiting or avoiding these foods may be beneficial for individuals with asthma in order to reduce inflammation, immune response, and the potential for allergic reactions.
2. Dementia and Diet
In the book “How Not to Die,” Dr. Michael Greger explores the relationship between diet and various health conditions, including dementia. Dementia is a devastating condition that affects millions of people worldwide, and finding ways to prevent or slow its progression is of utmost importance.
Dr. Greger discusses how certain dietary choices can impact the risk of dementia. He emphasizes the importance of consuming a plant-based diet rich in fruits, vegetables, whole grains, legumes, nuts, and seeds. These foods are abundant in antioxidants, vitamins, minerals, and phytochemicals that promote brain health and mitigate the risk of cognitive decline.
One particular class of nutrients that Dr. Greger highlights is flavonoids. Flavonoids are plant compounds found in a variety of colorful fruits and vegetables, such as berries, citrus fruits, and dark leafy greens. Research suggests that a higher intake of flavonoids may reduce the risk of cognitive decline and dementia. These compounds have antioxidant and anti-inflammatory properties that protect brain cells from damage.
In addition to highlighting beneficial dietary choices, Dr. Greger also discusses the detrimental effects of unhealthy food choices on brain health. He emphasizes the importance of avoiding processed foods, added sugars, and unhealthy fats, as these have been linked to an increased risk of dementia and cognitive decline.
Overall, Dr. Greger advocates for a whole-food, plant-based diet as the foundation for preventing dementia and maintaining optimal brain health. He provides evidence-based recommendations and highlights the importance of lifestyle factors such as exercise and sleep in combination with a healthy diet. By incorporating these dietary and lifestyle changes, individuals can take proactive steps towards reducing their risk of dementia and promoting long-term brain health.
3. Soy and Breast Cancer
One of the main claims made in Dr. Greger’s book is that consuming soy products can reduce the risk of breast cancer. However, this claim is not supported by strong scientific evidence.
The theory behind this claim is that soy contains phytoestrogens, which are plant compounds that can mimic estrogen in the body. Estrogen is known to promote the growth of hormone-receptor-positive breast cancer cells. Therefore, it is believed that consuming soy products, which contain phytoestrogens, may reduce the risk of breast cancer by blocking estrogen from binding to the receptors in breast tissue.
While there have been numerous studies conducted on the relationship between soy consumption and breast cancer risk, the results have been inconsistent. Some studies have indeed suggested a protective effect of soy consumption, while others have shown no significant association. Additionally, a few studies have actually found an increased risk of breast cancer associated with high soy consumption.
One possible reason for the conflicting results is that soy consumption varies greatly among different populations. In countries like Japan, where soy consumption is high, breast cancer rates are relatively low. However, in countries like the United States, where soy consumption is lower, breast cancer rates are higher. This indicates that factors other than soy consumption may play a more significant role in breast cancer risk.
Furthermore, the studies conducted on soy and breast cancer have mostly been observational in nature, meaning they can only establish an association and not a cause-and-effect relationship. Randomized controlled trials, which are considered the gold standard of evidence, have failed to find a significant protective effect of soy consumption against breast cancer.
In conclusion, while some studies have suggested a potential protective effect of soy consumption against breast cancer, the overall scientific evidence is not strong enough to make definitive conclusions. It is important to consider various factors such as genetics, lifestyle, and overall diet when assessing breast cancer risk. As always, it is best to consult with a healthcare professional for personalized advice.

1. Infections From Meat
Dr. Michael Greger’s book, “How Not to Die,” explores the link between diet and common health issues. One of the key points he raises is the risk of infections from meat consumption.
|Commonly found in raw or undercooked poultry, eggs, and ground meat.
|Often present in undercooked beef and other contaminated sources.
|Frequently found in deli meats and soft cheeses.
|Often associated with poultry and unpasteurized milk.
These infections can cause a range of symptoms, from mild gastrointestinal discomfort to severe illness and even death. Dr. Greger emphasizes the importance of proper cooking techniques and food safety practices to reduce the risk of these infections.
Furthermore, he highlights the growing concern of antibiotic-resistant bacteria in meat. The routine use of antibiotics in animal agriculture contributes to the development of resistant strains, which can pose a significant threat to human health.
Dr. Greger advocates for a plant-based diet as a way to reduce the risk of these infections and promote overall health. By avoiding meat consumption, individuals can minimize their exposure to harmful bacteria and contribute to a more sustainable food system.
2. Cooked Meat and Carcinogens
In his book “How Not to Die,” Dr. Michael Greger explores the impact of cooked meat on our health. He delves into the potential dangers of consuming cooked meat and the presence of carcinogens in our food.
Dr. Greger highlights the fact that when meat is cooked at high temperatures, such as grilling or frying, it can produce carcinogens called heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). These compounds have been linked to an increased risk of various types of cancer, including colorectal, pancreatic, and prostate cancer.
The formation of HCAs and PAHs occurs when amino acids, sugars, and creatine react at high temperatures. The longer and hotter the cooking, the higher the formation of these carcinogens.
Dr. Greger emphasizes that reducing or eliminating the consumption of cooked meat can significantly lower the intake of HCAs and PAHs, thus reducing the risk of cancer. He suggests opting for healthier cooking methods, such as boiling, steaming, or poaching, which produce fewer carcinogens.
Furthermore, Dr. Greger recommends incorporating more plant-based foods into our diet. Fruits, vegetables, whole grains, legumes, and nuts not only provide essential nutrients but also have a protective effect against cancer.
In conclusion, the book “How Not to Die” highlights the potential dangers of consuming cooked meat and the presence of carcinogens in our food. Dr. Greger emphasizes the importance of reducing the intake of cooked meat, opting for healthier cooking methods, and incorporating more plant-based foods into our diet to reduce the risk of cancer.
