We all know that a good diet is important for optimal health, but a leading American doctor is conquering the medical world with the disclosure that specific compounds in certain foods can stimulate the body's natural defenses against life-limiting diseases.


As a doctor who has treated thousands of patients and a scientist who is at the forefront of modern medicine, Harvard expert Dr. William Li convinced that the most powerful way to beat diseases – from cancer to dementia – is to prevent them in the first place.

His work depends on the study of five important defense systems in our body: our immune system, our stem cells, our DNA, our intestinal bacteria and the advanced functioning of our blood vessels. If they work well, they keep us healthy, but they put pressure on age, inactivity, stress, poor nutrition and toxic load – for example from air pollution, smoke and processed food – and that is when illness can creep in.

Dr. Li has used more than 30 years of medical research and more than 700 scientific studies to determine which foods best support these systems. Based on these findings, he has written a groundbreaking new book that will only be serialized throughout this week in this four-page pull-outs, as part of the Good Health for Life month of Daily Mail.

On Saturday, the Mail gave away an exclusive Wellness Journal to inspire you to improve your health and well-being.

Every day this week we will draw attention to one of the five systems and reveal specific foods that support it, starting today with possibly the most important: the system that supports the growth and health of blood vessels.

First take the quiz on the back of this excerpt to get a good idea of ​​your current health status. This will help you determine how much support your defense systems need.

We are really at a turning point in the fight against diseases. Each of us has a tremendous opportunity to take charge of our lives by using food to transform our health.

Our health systems are set up to step in once the disease has declared its presence, but this has left us with a large number of people who now rely on expensive medicines that often cannot return their health to them.

As the burden of disease increases, healthcare systems around the world are squeezing under this enormous financial pressure.

I believe that a much better route to optimal health and a long life without disease lies in eating the right foods, and advanced scientific testing techniques allow us to locate the specific compounds in certain foods that activate or support crucial disease-fighting processes in the body.


This revolution in information means that we can be much more advanced with our food choices, by choosing only food to support specific functions – we can even have the precise & # 39; food dose & # 39; Suggest to boost your defense against dementia, high blood pressure, rheumatoid arthritis or type 2 diabetes. We all know the saying & # 39; an apple a day keeps the doctor away & # 39; and to a certain extent we now know that this is true – apples are a great source of nutrients for plants, vitamins and fiber.

But we now have research data to show that one apple, preferably a Granny Smith or Red Delicious, contains precisely the bioactive substances (namely caffeine and ferulic acid) that your body needs to break down the mechanisms of specific bladder, colon and lung cancer. to help combat.

Findings such as these place us at an important turning point in the fight against diseases.

My research has shown that our health is protected by a series of five remarkable defense systems that work hard to make our cells and organs function smoothly.

These systems are wired to protect us by resisting the regular dangers that we all face every day (such as air pollution and aging) and by initiating a healing process when the disease strikes. The big five are: your immune system, your stem cells, your DNA, your intestinal bacteria and the advanced functioning of your blood vessels (a process called angiogenesis).


These five defense systems are important pillars for your health. Each of the systems is influenced by nutrition.

If you know what to eat to support every health defense, you can use your diet to beat illness.

We now know that certain compounds in specific foods have a powerful impact on some, some or all of these systems that activate and support their capabilities to keep us healthy.


Most of the best foods are fruits and vegetables – which is a way to explain the health-promoting effects of plant diets, and why we are all encouraged to try eating five (or, preferably, more) portions of fruit and vegetables per day.

But now we can determine exactly which food best supports each defense system and this is the key to using your diet to maintain your health and beat disease.

Foods are now being tested using the same processes used to develop medicines and studies show exactly how certain foods can activate each system.

Choose the right food every day and you can be confident that you are doing the best you can to protect yourself against illness and illness.

Everyone is afraid of getting sick. If your goal is to stay healthy, and especially if you are fighting a disease, you want reliable information based on science and fact, and useful steps that you can now take to improve your situation.


There is no "silver bullet" for an illness or for overall health and longevity. No factor in our lives is going to prevent disease. But my research shows that we have something better.

There is a way to boost our own immune system so that the body will heal itself.

These revelations tell us that we have radically underestimated our power to transform and restore our own health.

If your goal is to extend the number of healthy years that you have left, your food choices can bring the odds to your advantage.

By stimulating your immune system and keeping it in good condition, you can beat diseases better and not only extend the length but also the quality of your life.
