Landmark Study Published in Nature Medicine and Presented at
BOSTON and LONDON, June 12, 2020 /PRNewswire/ -- Health science company ZOE announced today the first published results from PREDICT, the largest ongoing nutritional study of its kind. The results, published in Nature Medicine and abstracts shared at the American Society of Nutrition show a wide range of inflammation responses after eating, even amongst apparently healthy people. Dietary inflammation is linked with increased risk for conditions such as heart disease, type 2 diabetes and obesity. The study suggests improved weight management and health could be achieved by eating food that are personalized to reduce dietary inflammation.
ZOE will launch a new test kit and app in July that uses AI to develop personalized eating plans based on a person's unique gut microbes and dietary inflammation. They have launched today a waitlist for customers eager to access the new kit.
"When it comes to weight, we've traditionally put a huge emphasis on factors we have no control over, like genetics," said Tim Spector, MD FRCP FRSB, scientific co-founder of ZOE, senior researcher of the PREDICT study and Professor of Genetic Epidemiology, King's College London, UK. "The fact is, while genetics plays a role, there are many more important factors that impact an individual's response to food and maintenance of a healthy metabolism. This study shows that achieving a healthy weight requires a scientific approach to eating that takes into account an individual's unique biology."
Led by Professor Tim Spector and his team at King's College London and ZOE, in collaboration with Massachusetts General Hospital and additional researchers in the US, UK, Italy, Spain and Sweden,* the PREDICT-1 study recruited participants across the UK and the US. This consisted of 1,103 subjects including 660 identical and non-identical twins from the TwinsUK cohort. The study measured a wide range of markers from blood glucose, fat and insulin levels to exercise, sleep and gut bacteria (microbiome).
Every PREDICT participant attended a full hospital day at the start of the study for detailed blood measurements and testing of responses after eating set meals with carefully controlled calorie, fat, protein, carbohydrate and fiber content. They then carried out the rest of the study at home, eating a schedule of set meals and their own free choice of foods.
Participants wore a continuous glucose monitor and activity tracker throughout the duration of the study, took finger prick blood samples to monitor blood fat levels and collected stool samples for microbiome analysis.
Despite wide variation in nutritional responses between participants, results from identical meals eaten on different days showed that individual responses to the same foods were remarkably consistent for each person. Raised levels of blood sugar and blood fat can lead to inflammatory responses via oxidative stress and lipoprotein remodelling.
"When we looked at blood sugar and fat levels across participants who ate the same meal, we could see up to ten times difference in their bodies' response," said Andrew T. Chan, MD, MPH, at Massachusetts General Hospital and Professor at Harvard Medical School. "Many people who would traditionally be viewed as healthy, showed real signs of metabolic stress after eating certain foods. By using AI to predict responses to these meals, we're able to identify a combination of foods for an individual that could reduce potentially harmful inflammatory processes that have been linked to obesity, heart disease, diabetes, fatty liver, and cancer."
PREDICT-1 study results showed:
- Genetics plays a minor role in determining personal nutritional response and even identical twins can respond very differently to the same foods. This suggests that tests offering personalized nutrition advice based only on genetic information are ineffective.
- Everyone is unique in the way their bodies respond to eating food (nutritional response), so there is no one "right" way to eat. Traditional standardized diets (e.g., low carb diet, low calorie diet, etc.) and meal plans therefore miss the mark.
- The optimal time to eat for nutritional health also depends on the individual rather than fixed "perfect" mealtimes. The researchers found that some people clearly metabolized food better at breakfast while others saw no difference. This is the subject of ongoing research.
- Optimal meal composition in terms of fat, carbohydrates, proteins and fiber (macronutrients) is also highly individual, so prescriptive diets based on fixed macronutrient ratios are too simplistic and will not work for everyone. For example, a sensitive glucose responder may need to reduce carbohydrates whereas someone else may be able to eat these freely.
- The relationship between the calories consumed in a meal and nutritional response is weak and the form a food is in (cooked, chopped, ground) will produce a drastically different result.
The ZOE plan: Harnessing AI for Better Health
Using this ongoing research, the ZOE team in partnership with scientists around the world has developed a new personalized eating plan that will help you hit your healthiest weight by reducing dietary inflammation and supporting your gut. This is not a diet or calorie restriction plan. The at home test kit is based on the novel tests developed for this study but easy to use and offers insights into your unique gut microbes and dietary inflammation. Once you've tested your body, you'll be given your insights and a personalized program to reduce dietary inflammation and boost healthy gut microbes. ZOE's AI powered app makes following the plan easy and offers personalized scores to a large number of foods, delicious recipes and insights that teach you clever ways to continue to eat the foods you love.
The ZOE plan is currently accepting people to its 20,000 strong waitlist and will be available to early applicants this July. Register to apply here: joinzoe.com/signup.
The company is also the creator of the COVID Symptom Study app, which uses AI and symptom data to predict the spread of COVID-19 in real-time. The app has 4 million users globally, with multiple scientific papers in journals such as Science and Nature Medicine. Data from the COVID Symptom Study app confirms that people who are obese are more likely to end up in hospital with COVID-19. People living with diabetes, cancer and heart disease are also at increased risk of hospitalisation. Public health efforts are increasingly focused on reducing the health impacts of many conditions associated with poor nutrition and being overweight, including COVID-19.
About the PREDICT Studies
The PREDICT (Personalized REsponses to Dietary Composition Trial) studies are the world's largest ongoing program of nutrition research. This program of research exists to understand the role of personalized nutrition and the gut microbiome to solve complex, food related health issues including chronic disease and metabolic syndrome. The studies are led by ZOE in collaboration with researchers and scientists at Massachusetts General Hospital, Harvard Medical School, Stanford Medicine, Tufts University and King's College London.
PREDICT 1: The study included 1,103 U.K. and US participants including identical twins to understand the role of genetics and the microbiome in personal nutrition. Forthcoming scientific papers include findings on the factors that contribute to hunger and energy lulls, and post-meal fat response and its influence on dietary inflammation.
PREDICT 2: Studied 1,100 US participants and recently completed in March 2020. This study included complex microbiome profiling which has led to the discovery of a specific microbe that may determine your ability to metabolize food better. Initial findings will be published later in the year.
The next stage of the PREDICT studies will be announced soon.
ZOE is a health science company using data-driven research to tackle the world's health issues.
