The Power Of Plants: How We Can Fight Chronic Diseases With Food

Fighting Chronic Diseases

Can we stop, manage and even reverse many of the world’s most common chronic diseases simply by changing what we eat? The short answer is yes! Here we explain both how and why food matters so much when it comes to life threatening conditions like heart disease, stroke, diabetes, many forms of cancer, and other lifestyle related illnesses.

Heart Disease and Stroke

Nothing kills more Americans than heart disease and stroke. More than 859,000 Americans die of heart disease or stroke every year, which equates to one-third of all deaths. These diseases take an economic toll, as well, costing the U.S. healthcare system $199 billion per year and causing $131 billion in lost productivity on the job.

In the case of stroke, coronary and vascular heart disease and peripheral arterial disease (PAD), there is strong human evidence that a plant-based diet rich in fruits, vegetables, legumes and wholegrains can be very beneficial in managing, halting and even reversing these life-threatening diseases. Meanwhile, the role of dairy, oils and fats is controversial, and the role of meat, poultry, eggs, processed and refined foods appear to be detrimental.

While a rapidly growing number of medical professionals and healthcare systems now recognize the effectiveness of a WFPB diet in treating heart disease, Million Dollar Vegan supporters Dean Ornish, M.D. and Caldwell Esselstyn, M.D. were the first medical professionals to research and demonstrate how comprehensive lifestyle changes may begin to reverse even the most severe coronary heart disease without the aid of drugs or surgery.

To this very day, Ornish and Esselstyn are showing people around the world how to use food to manage, reverse and reduce their risk of this killer disease.

Each year in the United States, more than 1.6 million people are diagnosed with cancer, and almost 600,000 die from it, making it the second leading cause of death. The cost of cancer care continues to rise and is expected to reach almost $174 billion by 2020.

Regardless of its cause, cancer only becomes a disease once malignant cells evade our immune system, which is why the most innovative cancer treatments are immunity boosting. As we learned in chapter 5, a WFPB diet can boost our immune system too.

In 2008, Million Dollar Vegan supporter Dr. Dean Ornish published landmark research showing that comprehensive diet and lifestyle changes could slow, stop or reverse the progression of early-stage prostate cancer. This was tied to the fact that our diet and lifestyle can affect gene expression, “turning off” genes that promote cancer and heart disease.

In his seminal work, The China Study, biochemist T. Colin Campbell showed that cancer development is primarily a nutrition-responsive disease rather than a genetic one, and that high-antioxidant WFPB nutrition has a positive biological effect on our body’s defense systems, enabling them to control and, on occasion, even reverses cancer development.

Controlled studies also showed that animal-based protein and dietary fat consumption has the opposite effect on cancer, by turning tumor development “on”. The World Health Organization (WHO) has responded to this evidence by classing processed meats (deli-meats, ham, chorizo, pepperoni, bacon, sausage, etc) as a Group 1 carcinogen, putting it in the same cancer-causing category as smoking. Non-processed meats, such as beef, lamb and pork, have also been classified as carcinogenic and a probable cause of cancer.

Furthermore, dairy products (milk, yoghurt, cheese) are linked to prostate cancer and also associated with an increased risk of lung cancer, breast cancer, and ovarian cancer in people with lactose intolerance. The Life After Cancer Epidemiology study found that, among women previously diagnosed with breast cancer, those consuming one or more servings of cheese, ice cream, or whole milk daily had a 49 percent higher breast cancer mortality, compared with those consuming none.

More than 30 million Americans have diabetes, and another 84 million adults in the United States have a condition called prediabetes, which puts them at risk for type 2 diabetes. Diabetes can cause heart disease, kidney failure, and blindness, and costs the U.S. healthcare system and employers $237 billion every year.

Studies show that eating a high-fat, standard American diet can cause fat particles to build up inside our cells. These fat particles interfere with insulin’s ability to move sugar out from our bloodstream and into our cells, so instead of powering our cells, the glucose remains in our bloodstream, eventually leading to diabetes.

A WFPB diet, which is naturally low in fat, is a powerful tool for preventing, managing, and even reversing type 2 diabetes because it allows insulin to function properly. It has been shown to be effective at reducing and managing symptoms of type 1 diabetes as well.

In a 2003 study funded by the NIH, The Physicians Committee for Responsible Medicine tested thousands of patients with type 2 diabetes and determined that a plant-based diet controlled blood sugar three times more effectively than a traditional diabetes diet that limited calories and carbohydrates. Within weeks on a plant-based diet, participants saw dramatic health improvements. They lost weight, insulin sensitivity improved, and HbA1c levels dropped. In some cases, you wouldn’t even have known they’d had the disease at all.

Nutritional Biochemist, Dr. Cyrus Khambatta, was diagnosed with type 1 diabetes in 2002, and has, for the past decade, been educating people with type 1 diabetes, type 1.5 diabetes, prediabetes and type 2 diabetes how to reduce reverse insulin resistance through a WFPB diet and exercise with outstanding patient results.

Obesity affects almost 1 in 5 children and 1 in 3 adults in America. It is associated with 400,000 deaths a year and an increased risk of heart disease, type 2 diabetes, and colon, breast, and endometrial cancers. Most poignant is the psychological pain of those stigmatized by obesity.

Few things are as important to Americans as affordable healthcare and the military, yet a quarter of all Americans aged 17 to 24 are too heavy to join the military, and obesity costs the U.S. healthcare system $147 billion a year. So where did it all go so wrong?

To start with, many people are confused about what it takes to maintain a healthy weight. The internet is awash with misinformation and so-called “scientific” studies that, if you look closely, are often little more than elaborate marketing ploys by the food industries that funded them.

Meanwhile, fads diets that give rapid but short-lived results – such as Atkins, Keto and Paleo – have lead us to believe that a high-fat low-carb might be the answer. But these diets, characterized by their exclusion of important food groups such as complex carbohydrates and nutrient-rich fruits and vegetables, are not sustainable and risk leaving us nutrient deficient and unhealthier in the long-term. Studies even show that, in the long-term, diets like these are linked with an increased risk of death from any cause, including cardiovascular disease, cerebrovascular disease, and cancer.

At the same time, the convenience of processed junk food over wholesome, fresh produce, does us no favors whatsoever. But let’s get this straight: losing weight or maintaining a healthy weight may not be the most “convenient” option, especially when there’s a fast-food restaurant on every corner; but it’s not a riddle either. It doesn’t need to involve costly foods or complicated meal plans, and it definitely doesn’t involve calorie counting, carb-counting, or scales. What it does involve is eating ONLY foods that nurture your body and breaking-up with those that don’t.

“Look, I’d love to tell people it’s OK to eat bacon and sausage, but it’s not. You can lose weight in ways that aren’t good for you. Smoking causes you to lose weight, as do amphetamines. But it’s not just about losing weight, it’s losing weight in a way that is helpful.” – Dean Ornish, M.D.

In his bestselling book, Proteinaholic, Dr. Davis demonstrates that it’s calories, not carbs, that contribute to weight gain, and that it’s the hidden calories in refined and processed foods that tend to be our biggest downfall. Without us even realizing it, the most innocent-looking convenience foods, like pasta sauces, salad dressings, refined white bread, and deceptively labelled “low fat” foods, can often contain added oil, sugar, and an abundance of empty calories.

Oils in particular are very calorie dense, and even a few squirts of your “low calorie” cooking spray can affect your ability to lose weight. Potatoes, on the other hand, are the mainstay of many of the healthiest societies in the world, and one of the most heart-healthy, satiating, low-fat whole foods you can eat. Just make sure you bake, boil or air-fry your potatoes rather than buying them at a drive-thru!

Ultimately, a WFPB diet rich in fruits, vegetables, legumes, grains, and unrefined complex carbohydrates like potatoes, brown rice and wholegrains, is naturally very low in calories and yet, due to its high fiber content, also very satisfying. Furthermore, you can eat as many whole plant foods as you want and still lose weight, provided they come with no added oil or sugar.

Within weeks of embarking on a WFPB diet, you should start to feel lighter and more energized. Studies show that losing just 5-10% of your total body weight is likely to produce health benefits such as lowered blood pressure, blood cholesterol, and blood sugars, so even before you see big changes in your physical appearance, your overall health will improve.

Alzheimer’s Disease

Alzheimer’s disease, a type of dementia, is an progressive brain disease that affects about 5.7 million Americans. It is the sixth leading cause of death among all adults and the fifth leading cause for those aged 65 or older. In 2010, the costs of treating Alzheimer’s disease were estimated between $159 billion and $215 billion, and by 2040 these costs are projected to jump to between $379 billion and $500 billion annually.

While there is no known cure for Alzheimer’s disease or dementia, there is a way to prevent cognitive decline, to slow its progression and improve the quality of life for those who already have a diagnosis. And what most of the 47 million people living with Alzheimer’s worldwide don’t know is that by making the right lifestyle choices they could have reduced their risk of developing this devastating disease by up to 90%.

This staggering statistic is often discussed by pioneering neurologists Doctor’s Dean and Ayesha Sherzai, co-directors of the ‘Brain Health and Alzheimer’s Prevention Program’, who, through their award-winning work, have found that one of the biggest factors in our long-term neurological health is what we choose to put on our plates.

Scientists have suggested that Alzheimer’s is essentially a garbage disposal problem: the brain’s inability to cope with the junk we’ve fed it over a lifetime, which makes a lot of sense. Poor nutrition can damage our brain in numerous ways; causing inflammation (a hallmark of obesity and chronic illness), clogging blood vessels (the cause of cardiovascular disease and stroke), and depriving our brain of the nutrients it needs to function optimally. Though our brain may only seem like a small part of us, it actually uses up to 25 percent of the body’s energy and, because food is energy, our brains are especially vulnerable to each nutritional choice we make.

Nobel prize-winning physician Dr. Dean Ornish is currently directing the first randomized controlled trial to determine if comprehensive lifestyle changes can reverse the progression of early Alzheimer’s disease, with positive results expected. Meanwhile, existing studies show that eating a predominantly plant-based diet can reduce the risk of Alzheimer’s by up to 53 percent, while exercise can reduce risk of the disease by 40 percent and stroke by 25 percent.

The evidence that “brain food” exists is therefore very promising, and all the more reason to get active and to adopt a whole-food plant-based lifestyle:
