There are some books you read and move on from… and then there are the ones that stay with you long after the last page. “How Not to Die”, a great book written by Gene Stone and Michael Greger felt like that for me, and for many members of the GLC Community (Click HERE to learn more about GLC). Most of us have started applying the lessons from the book.
For me, I read the book slowly, and what stayed with me was realising how much of our health is quietly shaped by the small, everyday choices we treat as normal. At its core, the book keeps returning to one clear idea: many of the diseases we fear do not just happen to us randomly. They often grow from patterns, especially what we eat, and those patterns can be changed (if you really want to).
Here’s a breakdown of the book with the practical steps we can all take to live a healthy life.
Brain Disease: Brain health isn’t something to think about only in old age. It’s something that shapes how we live, think, feel, and function every single day. We all need a healthy, functioning brain to enjoy a good quality of life. Our memory, focus, mood, decision-making, and even emotional balance all depend on how well the brain is supported over time. Conditions like stroke and Alzheimer’s are influenced by long-term habits, including what we eat. Diets high in salt, saturated fats, and processed foods can raise blood pressure, increase clot risk, and gradually affect brain function over time. It often comes down to small daily choices, what you spread on your bread, your snacks, what fills your plate. Swapping butter for olive oil, adding spinach, or choosing blueberries over biscuits may feel small, but they add up. Foods like berries, leafy greens, nuts, flaxseeds, and whole grains help support and protect the brain over time.
Heart Disease: Heart disease is still the leading cause of death worldwide, yet many people feel fine until something suddenly goes wrong. What’s surprising is that plaque (fat buildup in the arteries), can start forming as early as childhood, long before symptoms appear. Over time, it narrows the arteries and slows blood flow, and if it ruptures, it can trigger a clot that leads to a heart attack. The encouraging part is that it’s largely preventable. In places like rural China and Uganda, where diets are built around grains, legumes, and vegetables, heart disease is rare. Whole-food, plant-based eating doesn’t just lower cholesterol, it can even help reverse arterial damage. Choosing more beans, leafy greens, and fruits, while cutting back on animal fats and processed foods, makes a difference. Even simple swaps, like oatmeal with berries instead of bacon, matter.
Digestive Cancers: Our gut is more than a digestive system. It’s a key part of our overall health. Fiber-rich foods like beans, whole grains, fruits, and vegetables feed good gut bacteria and help the body clear out harmful substances. On the other hand, diets high in red and processed meats, excess sugar, and fried foods increase cancer risk. Adding turmeric, cruciferous vegetables, and colorful produce to improve our gut health. Simply put, your plate becomes part of how you protect your gut every day.
Infections: I don’t think we talk enough about how much what we eat supports our immune system. It’s not just about avoiding germs, it’s about whether your body is ready for them when they come. Some animal products can expose us to pathogens, while plant foods quietly strengthen our defense system. Foods like garlic, mushrooms, green tea, and colorful fruits and vegetables give your body what it needs to fight foreign substances. Choosing more plant-based meals isn’t only about preventing long-term diseases; it’s about equipping your body daily to stay healthy.
Diabetes: For a long time, many of us thought sugar was the main problem. But it goes deeper than that. When there’s too much fat, especially from animal sources and processed foods, it interferes with how insulin works. The beautiful part is that the body responds when we make changes. Foods like beans, whole grains, nuts, and even simple additions like cinnamon or a splash of vinegar can help stabilize blood sugar. There are real stories of people turning things around just by changing how they eat. And yes, you can do the same.
High Blood Pressure: High blood pressure is often seen as something that just comes with age, but that’s not the full story. What we eat plays a huge role. Diets high in processed foods, excess salt, and animal products can push blood pressure up over time. On the other hand, foods rich in potassium—like bananas, beans, leafy greens, beets, and flaxseeds—help bring it down naturally. In some cases, these changes can be just as effective as medication, without the extra burden on the body.
Liver Disease: Your liver is constantly working for you behind the scenes, and it is affected by more than just alcohol. Diets high in animal fat, sugar, and refined carbs can lead to fat buildup in the liver. The encouraging part is that the liver can heal when you support it adequately. Eating more plant-based foods, especially vegetables like broccoli and cabbage, and reducing or completely eliminating alcohol, can help reduce that burden and even reverse early damage.
Kidney Disease: The kidneys do a lot of quiet work filtering waste from the body. When we consume too much animal protein, it can put extra strain on the kidneys over time. Shifting towards plant proteins, along with fruits, vegetables, and foods like flaxseeds, can ease that load. For people already dealing with kidney issues, healthy diets can help slow down the progression of the disease and support better function for longer.
Cancer: Cancer isn’t one single disease, and it rarely has one single cause. It builds up over time from a mix of genetics, environment, and lifestyle patterns. What research keeps pointing to is a pattern: diets high in processed meats, alcohol, ultra-processed foods, and excess body fat are linked with higher cancer risk, while diets centered on whole plant foods: vegetables, fruits, legumes, nuts, and whole grains, are linked with lower risk and better overall health outcomes.
In blood cancers like leukemia, lymphoma, and myeloma, the causes are still complex and not fully understood. Nutrition is not a treatment, but the way we eat can still matter. It supports immune function, reduces inflammation, and help the body stay stronger through management, treatment, and recovery. For breast cancer, risk is shaped by a combination of hormones, genetics, age, and lifestyle. Alcohol and excess body fat are well-established risk factors, while plant-rich, high-fiber diets are associated with better outcomes and lower recurrence risk in survivors. In prostate cancer, research suggests a pattern as well. Higher intake of processed meats and some high-fat animal foods may be linked with increased risk, while plant foods like tomatoes, legumes, soy, and cruciferous vegetables are associated with better prostate health outcomes in several studies.
In summary, less ultra-processed food, processed meat, and alcohol can reduce the risk of cancer. Eating more whole plant foods is an evidence-backed way to support the body and reduce risk over time.
Suicide and Depression: Mental health is not separate from physical health. What we eat affects how we feel more than we sometimes realize. Whole plant foods help reduce inflammation and support both gut and brain health. Simple foods like flaxseeds, chia seeds, and walnuts provide nutrients the brain needs. Even small steps like adding vegetables to your meals or choosing fruit as snacks can make a difference in mood and emotional resilience over time.
Iatrogenic Causes: Iatrogenic causes simply refer to harm that can sometimes come from medical treatment itself. In other words, the very interventions meant to help, like medications, procedures, or hospital care, can occasionally lead to side effects or complications. That’s why prevention matters so much. The less we rely on medications, surgeries, and hospital interventions, the lower the risk of complications. And one of the most powerful ways to prevent disease is through what we eat and how we live. A whole-food, plant-based diet, along with regular movement, is one of the simplest ways to take care of your health from the foundation.
Daily Habits and Foods That Save Lives
Dr. Greger’s work highlights some simple daily habits that are consistently associated with better long-term health:
1. Beans: about 3 servings a day – support lower cholesterol, steady blood sugar, and a healthy gut. Common examples include lentils, chickpeas (garri/beans, hummus), black beans, kidney beans, and soybeans.
2. Berries: 1 serving a day – support brain and heart health and provide protective plant compounds. Common examples include blueberries, strawberries, blackberries, and raspberries.
3. Other Fruits: about 3 servings a day – provide fiber, vitamins, and overall disease protection. Common examples include oranges, apples, bananas, mangoes, pineapples, pawpaw (papaya), and watermelon.
4. Cruciferous Vegetables: 1 serving a day – support normal liver function and are associated with lower cancer risk. Common examples include broccoli, cabbage, cauliflower, kale, and Brussels sprouts.
5. Leafy Greens: 2 servings a day – support blood flow and brain and heart health. Common examples include spinach, ugu (pumpkin leaves), kale, lettuce, and waterleaf.
6. Other Vegetables: 2 servings a day – help ensure a broad range of nutrients. Common examples include carrots, tomatoes, peppers, cucumbers, onions, okra, and eggplant.
7. Flaxseeds: 1 tablespoon a day – provide plant-based omega-3s and support hormone balance. Common examples include ground flaxseeds (linseeds) added to smoothies, oats, or pap.
8. Nuts: about ¼ cup a day – support heart and brain health through healthy fats. Common examples include walnuts, almonds, groundnuts (peanuts), cashews, and pistachios.
9. Spices (especially turmeric): small daily amounts – provide anti-inflammatory and antioxidant benefits. Common examples include turmeric, ginger, garlic, cinnamon, and cloves.
10. Whole Grains: about 3 servings a day – support steady blood sugar, heart health, and gut function. Common examples include oats, brown rice, whole wheat, millet, maize, and sorghum.
11. Beverages: about 5 cups a day of water, green tea, or coffee – support hydration and overall metabolic health.
12. Exercise: daily movement – walking, strength, and flexibility for long-term vitality. Examples include brisk walking, skipping, bodyweight exercises, stretching, or dancing.
At the end of it all, what stands out is this: your health is shaped quietly by your daily choices. You may not be able to change everything overnight. Just start with something as simple as adding more greens and drinking more water. Be a little more intentional about what you eat.
That’s enough for a beginning. Because we’re not just eating for today. We’re shaping the kind of life our bodies will have to carry tomorrow.
