Food Doses: How Much of Each Food Should You Eat to Beat Disease - Dr William Li

By
Did you know that you can test the healing properties of foods in the same ways in which you test pharmaceutical drugs? It’s true. You can make decisions about what to eat and drink based on scientific evidence gleaned from testing foods with the same systems and methods that have been used to develop certain drug therapies. And the data generated when we study food like medicine clearly show that food can influence our health in beneficial ways. That is why I decided to write my book, Eat to Beat Disease. It examines many of the data-driven ways in which we can use certain foods to combat and prevent illness. But one common factor that many people have a challenging time addressing is how much of a certain food they should eat to achieve optimal health. So, let’s talk about food doses!

One key element of the “food as medicine” movement is the idea that there are certain doses of food that have been shown to thwart illness. When I say you can eat to beat disease, this is precisely what I am talking about. Numerous books tell you what foods to eat, but I want to talk about the optimal amount of those foods to consume. Just as there are ideal doses for pharmaceutical drugs, there is an effective disease-beating prescription for many of the foods that we consume every day.

 

What is a food dose? 

A food dose is the amount of any food or beverage consumed that is associated with or leads to a specific health outcome. For example, how many apples must you eat to reduce the risk of a given disease? When we talk about ideal food doses, it may be in relation to disease prevention, treatment, long-term management, or suppression to keep the disease from returning. Like medicines, bioactives in foods can influence our cells and the biological systems in our body in ways that resemble drugs.

Researchers like myself and my team at the Angiogenesis Foundation, where we examine foods, food extracts, and bioactives with rigorous scientific methods, are on the front lines of food dosing developments. Until recently, conversations about “healthy” food amounts have been centered on portion size. However, we can now apply new tools of molecular and cell biology as well as genomics to explore how food can support health in ways that weren’t possible even a few years ago.

Food doses: the specifics

Check out the chart below for several food doses of common foods and the diseases they positively impact from Eat to Beat Disease. Keep in mind, this is only some of the food doses for specific diseases. There are many more foods that can combat disease by promoting health through their activation of the five defense systems: angiogenesis, cell regeneration, the microbiome, immunity, and DNA protection. It is worth noting that many of the foods listed below can be consumed in the form of smoothies and soups, so obtaining the ideal dose should never be a concern.

The concept of food doses is relatively new and is one in which resources should continue to be invested. It is crucial for healthcare professionals and nutritionists to be educated on the topic of food doses as a cutting-edge tool for helping patients with varying illnesses recover. If the idea of food doses is of interest to you, check out my TED Talk where I discuss ideas such as the potency of different foods compared to drugs on angiogenesis and other bodily processes.
