About Gene Food

Gene Food was founded in 2016 by John O’Connor, an integrative health coach, and Dr. Steven Brody, a Stanford-trained endocrinologist and anti-aging doctor. The company specializes in DNA analyses for nutrition. Gene Food’s DNA samples are processed in their laboratory in San Francisco, California.

Review of Gene Food Products & Features

Gene Food offers a report that is generated by using a nutrition algorithm to investigate 20 different diet types. They analyze DNA to suggest the best diet for each genetic profile. They look at 150 SNPs to generate their report.

The company assesses scientific studies involving SNPs that may influence genetic dietary preferences and grades them according to their system, shown below. They claim this allows them to scientifically validate the resources they use for the products.

Gene Food scoring system

Users can purchase the Gene Food DNA test kit or upload preexisting genetic files from other companies like 23andMe and Ancestry. In both instances, the company provides a Custom Nutrition Plan with the same information. They assign each user the best diet from 20 different diet types analyzed, seen below. Each Custom Nutrition Plan comes with a 2-week meal plan and shopping list.

The company does not offer any medical advice and the genetic data analyzed does not address any medical condition. Gene Food examines some food sensitivities that can contribute to digestive problems.

Review of Gene Food Report

Gene Food’s report covers a variety of categories, including:

  • Macronutrient Recommendation: Informs on the best fat to carbs ratio based on DNA results.
  • Blood Sugar Analysis: Explains what types of carbohydrates the body can handle.
  • Plant Protein: Tells what percentage of protein should originate from plants.
  • Protein Metabolism: Explores how the body reacts to dairy, histamine, and plant proteins.
  • All About Fat: Offers information about fat metabolism, HDL to LDL ratio, and more.
  • Supplements: Tells which micronutrient might need supplementation.
  • Detox: Estimates how well the body can process environmental toxins.

The report shows an overview of the results explaining the type of diet selected for each genetic profile and proposes a few rules to optimize it. This section of the sample report is shown below.

Each section of the report offers an explanation of the subject, specific genetic results, and recommendations about diet and nutrition. Additionally, Gene Food also suggests a few topics to discuss with a doctor, such as lab results.

The micronutrients section seen below offers information on your vitamin and mineral needs and gives supplement suggestions. It also offers dietary recommendations including information on the availability of nutrients per food serving.

Gene Food's supplement recommendations

Gene Food also considers other factors such as sleep, tolerance to common anti-inflammatory products, and how users may react to cannabis. At the end of the report, they share the genetic variations that have the largest impact on the diet type, as seen below.

Cost of Gene Food

Gene Food’s Custom Nutrition Plan that includes a DNA test is priced at $185, but users can upload their preexisting genetic files and get the report for $95. 

They offer bulk discounts primarily for physicians and nutrition professionals but can also accommodate gyms or other large groups of people.

Health Recommendations from Gene Food

Gene Food is a company that focuses on diet and nutrition. They claim to evaluate 20 different diet types to assign the best one for each individual. They take into account many factors to provide their customers with a nutritional plan based on their DNA test results.

The report also gives supplement recommendations and explains the science behind each result. It also suggests a few lab tests to be discussed with a doctor to make sure the Custom Nutrition Plan is working, but does not offer the option for users to purchase lab tests from them.

The company makes it clear that they do not address any chronic medical conditions and they do not offer any report other than their Custom Nutrition Plan. They do not offer any other reports beyond this limited scope.

Review of Gene Food Privacy & Data Security

Gene Food’s website is HIPAA compliant, and they also adhere to the California Online Privacy Protection Act. They do not collect information on anyone under 13 years of age, in agreement with the Children’s Online Privacy Protection Act.

They state that any uploaded raw genetic data is deleted automatically after being analyzed by their system. The genetic files generated by their lab are stored short-term to allow users to access their raw genetic information. The company only stores a record of the SNPs analyzed for evaluating and recommending customers their ideal diet type.

Once the file is deleted, they claim to no longer have access to the genetic data. The company maintains that they do not share or sell information with third parties.

Gene Food Reviews

Since Gene Food is a new company, there are not many online reviews of their services.

DNAWeekly rates them 8 of 10. They say the report offers accessible information that can be easily implemented but comments on how it is not the most affordable DNA testing option.

22 reviewers on Trustpilot rated the company an average of 4.6 of 5 stars. Overall, customers are very satisfied with the service provided and say it is a good option for those who want to focus on their diet.

Alternatives to Gene Food

Gene Food Review Summary

Gene Food offers DNA-based dietary and nutritional recommendations. Instead of suggesting specific foods, the company chooses to recommend an optimal diet for each genetic profile by analyzing 20 different diet types.

The company provides macronutrient recommendations and recipes to match the assigned diet type. Additionally, they provide a list of all the genetic markers that could influence the results.

Gene Food offers good information for those who want to focus on their diet and nutrition, but they won’t provide you any other information beyond this limited scope. Overall health encompasses more than just those aspects. A service like SelfDecode analyzes up to 83 million genetic variants to provide personalized recommendations throughout their detailed wellness reports on over 30 health topics, including weight, cholesterol, and gut health, to name a few.
