Christopher David Gardner (born July 13,1959) is an American nutrition researcher. He is the director of nutrition studies at the Stanford Prevention Research Center and the Rehnborg Farquhar Professor of Medicine at Stanford University.
Gardner is involved with the American Diabetes Association (ADA) and the American Heart Association (AHA). In 2019,he was co-author of updated nutrition guidelines for the ADA. He served as a member of the AHA's Nutrition Committee from 2009 to 2013,and in 2020 he was appointed as a member of the AHA Lifestyle &Metabolic Health Council,and to a leadership position in the AHA Nutrition Committee (2020-2026). He appeared in the 2024 Netflix documentary You Are What You Eat:A Twin Experiment, about his Stanford University twins study. Gardner is an advocate and researcher of plant-based dietary patterns. [1] [2]
Gardner was born on July 13,1959,in Washington,D.C. [3] After earning his Bachelor of Arts degree in philosophy from Colgate University,he spent two years completing undergraduate science courses at the University of California,Davis and the University of California,Berkeley to qualify for a master's degree program in nutrition. Upon becoming eligible,he was accepted into the PhD program of Nutrition Science at the University of California,Berkeley. [4]
Upon completing a postdoctoral fellowship at Stanford University,Gardner accepted a position at the institution. [4] As an assistant research professor of medicine,Gardner collaborated with John W. Farquhar to study the effectiveness of ginkgo biloba supplements to treat peripheral artery disease. [5] The following year,he received a grant from the National Institutes of Health to study whether fresh garlic and garlic supplements lower cholesterol. [6] As an assistant professor of medicine at the Stanford Prevention Research Center,Gardner led the first independent,long-term,head-to-head assessment of raw garlic and garlic supplements. [7] He also oversaw the largest and longest-ever comparison of Atkins,Zone,LEARN or Ornish diets to see which led to the greatest weight loss and changes in cardiometabolic risk factors. [8] A follow-up to this study was the DIETFITS trial that compared a Healthy Low-Fat to a Healthy Low-Carbohydrate study with over 600 women and men. This landmark study tested whether there is a predisposition to success on one diet or the other based on either a potential genetic pattern or a metabolic condition known as insulin resistance. [9]
Gardner teaches a basic Human Nutrition class (HumBio 130),a Food and Society class (HumBio 166),and a Healthy and Sustainable Food Systems class (HumBio 113S) at Stanford. [10] From 2010 and 2015,he convened a series of annual Stanford Food Summits that involved faculty,students and researchers from across Stanford's seven schools. [11] These interests led him to be invited to join the Scientific Advisory Board of the Menus of Change,a collaboration between The Culinary Institute of America and Harvard T.H. Chan School of Public Health's Nutrition Department. [12] He is also the co-founder of a spin-off of this group,the Menus of Change University Research Collaborative,a group of colleges and universities using campus dining halls as living laboratories to explore opportunities to make changes in eating patterns at those institutions. [13] These activities have led to research studies and publications. In 2019,Gardner collaborated with a research team that included a food business consultant,an environmental scientist and a botanist to publish a review of protein requirements,current intakes,and potential beneficial impacts on the environment that would be realized in the US if protein intakes were lowered and shifted toward a more plant-based diet. [14]
Gardner is involved with the American Diabetes Association (ADA) and the American Heart Association (AHA). In 2019,he was an invited co-author of updated nutrition guidelines for the ADA. He served as a member of the AHA's Nutrition Committee from 2009 to 2013,and in 2020 he was appointed as a member of the AHA Lifestyle &Metabolic Health Council,and to a leadership position in the AHA Nutrition Committee. [10]
Gardner was appointed the Rehnborg Farquhar Professor of Medicine at Stanford which supports research in disease prevention in June 2017. [15] During the COVID-19 pandemic,Gardner found that replacing red meat with plant-based meat alternatives could lower some cardiovascular risk factors. [16] He also grew his interests in microbiome by collaborating with Stanford microbiologists,Justin Sonnenburg and Erica Sonnenburg,on several studies and with other microbiome researchers. [17]
In 2023,Gardner co-authored a scientific statement from the American Heart Association on popular dietary patterns and alignment with their 2021 dietary guidance. The DASH diet,Mediterranean diet,pescetarian and vegetarian eating patterns received top ratings for aligning with the Association’s dietary guidance whilst low-carbohydrate diet's scored poorly as they do not rank as heart-healthy eating patterns. [18] [19]
In 2023,Gardner published research on cardiometabolic risk factors in pairs of identical twins randomized to follow either a vegan or omnivorous diet. [2] The study found that a vegan diet was associated with statistically significant reductions in LDL cholesterol and fasting insulin levels. [20] This study is the subject of the 2024 Netflix documentary You Are What You Eat:A Twin Experiment. [21]
Gardner and his wife Melissa,a political scientist,have four sons together and all follow a plant-based diet. [22] One of Gardner’s sons,Jackson Gardner,completed his PhD at University of California,San Francisco,specializing in the microbiology of the gut microbiome.
Dairy products or milk products, also known as lacticinia, are food products made from milk. The most common dairy animals are cow, water buffalo, nanny goat, and ewe. Dairy products include common grocery store food around the world such as yogurt, cheese, milk and butter. A facility that produces dairy products is a dairy. Dairy products are consumed worldwide to varying degrees. Some people avoid some or all dairy products because of lactose intolerance, veganism, environmental concerns, other health reasons or beliefs.
Veganism is the practice of abstaining from the use of animal products—particularly in diet—and an associated philosophy that rejects the commodity status of animals. A person who follows the diet or philosophy is known as a vegan.
Vegetarianism is the practice of abstaining from the consumption of meat. It may also include abstaining from eating all by-products of animal slaughter.
A fad diet is a diet that is popular, generally only for a short time, similar to fads in fashion, without being a standard scientific dietary recommendation, and often making unreasonable claims for fast weight loss or health improvements; as such it is often considered a type of pseudoscientific diet. Fad diets are usually not supported by clinical research and their health recommendations are not peer-reviewed, thus they often make unsubstantiated statements about health and disease.
Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates are limited, and replaced with foods containing a higher percentage of fat and protein, as well as low carbohydrate foods.
The Mediterranean diet is a diet inspired by the eating habits and traditional food typical of southern Spain, southern Italy, and Crete, and formulated in the early 1960s. It is distinct from Mediterranean cuisine, which covers the actual cuisines of the Mediterranean countries, and from the Atlantic diet of northwestern Spain and Portugal. While inspired by a specific time and place, the "Mediterranean diet" was later refined based on the results of multiple scientific studies.
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy.
A plant-based diet is a diet consisting mostly or entirely of plant-based foods. Plant-based diets encompass a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich plant products such as vegetables, fruits, whole grains, legumes, nuts and seeds. They do not need to be vegan or vegetarian, but are defined in terms of low frequency of animal food consumption.
A healthy diet is a diet that maintains or improves overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
The China Study: The Most Comprehensive Study of Nutrition Ever Conducted and the Startling Implications for Diet, Weight Loss and Long-term Health is a book by T. Colin Campbell and his son, Thomas M. Campbell II. The book argues for health benefits of a whole food plant-based diet. It was first published in the United States in January 2005 and had sold over one million copies as of October 2013, making it one of America's best-selling books about nutrition.
A diabetic diet is a diet that is used by people with diabetes mellitus or high blood sugar to minimize symptoms and dangerous complications of long-term elevations in blood sugar.
The Dietary Approaches to Stop Hypertension or the DASH diet is a diet to control hypertension promoted by the U.S.-based National Heart, Lung, and Blood Institute, part of the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services. The DASH diet is rich in fruits, vegetables, whole grains, and low-fat dairy foods. It includes meat, fish, poultry, nuts, and beans, and is limited in sugar-sweetened foods and beverages, red meat, and added fats. In addition to its effect on blood pressure, it is designed to be a well-balanced approach to eating for the general public. DASH is recommended by the United States Department of Agriculture (USDA) as a healthy eating plan. The DASH diet is one of three healthy diets recommended in the 2015–20 U.S. Dietary Guidelines, which also include the Mediterranean diet and a vegetarian diet. The American Heart Association (AHA) considers the DASH diet "specific and well-documented across age, sex and ethnically diverse groups."
Vegetarian Diet Pyramid is a nutrition guide that represents a traditional healthy vegetarian diet. Variations of this traditional healthy vegetarian diet exist throughout the world, particularly in parts of North America, Europe, South America and, most notably, Asia. Given these carefully defined parameters, the phrase "Traditional Vegetarian Diet" is used here to represent the healthy traditional ovo-lacto vegetarian diets of these regions and peoples. A pyramid was created by Oldways Preservation Trust in 1998 with scientific research from Cornell and Harvard University and specific reference to the healthy patterns of eating demonstrated by the Mediterranean Diet Pyramid.
Intermittent fasting is any of various meal timing schedules that cycle between voluntary fasting and non-fasting over a given period. Methods of intermittent fasting include alternate-day fasting, periodic fasting, such as the 5:2 diet, and daily time-restricted eating.
Military nutrition is the field and study of food, diet, and nutrition in the military. It generally covers and refers to military rations and nutrition in military organizations and environments.
Michael Herschel Greger is an American physician, author, and professional speaker on public health issues, best known for his advocacy of a whole-food, plant-based diet, and his opposition to animal-derived food products.
Pescetarianism is a dietary practice based on the consumption of fish and shellfish to the exclusion of land-based meats. The practice incorporates seafood into an otherwise vegetarian diet, and may or may not include other animal products such as eggs and dairy products. Approximately 3% of adults worldwide are pescetarian, according to 2017–2018 research conducted by data and analytics companies.
Vegan nutrition refers to the nutritional and human health aspects of vegan diets. A well-planned vegan diet is suitable to meet all recommendations for nutrients in every stage of human life. Vegan diets tend to be higher in dietary fiber, magnesium, folic acid, vitamin C, vitamin E, and phytochemicals; and lower in calories, saturated fat, iron, cholesterol, long-chain omega-3 fatty acids, vitamin D, calcium, zinc, and vitamin B12.
As in the human practice of veganism, vegan dog foods are those formulated with the exclusion of ingredients that contain or were processed with any part of an animal, or any animal byproduct. Vegan dog food may incorporate the use of fruits, vegetables, cereals, legumes including soya, nuts, vegetable oils, as well as any other non-animal based foods.
You Are What You Eat: A Twin Experiment is a 2024 American documentary series set for streaming on Netflix. It is based on an 8-week study conducted by Stanford University that put 22 sets of genetically identical twins on opposing diets: omnivore and vegan. It was released on January 1, 2024.
