GeneFood provides an easy to understand nutrition plan that is ready within minutes of uploading raw DNA data. Customer reviews on the company’s website indicate they are pleased with their results. The price can be a bit high, especially if you include the price of the kit from a third-party seller.


This review is written with the intent to be as unbiased as possible. However, it represents the opinion of an individual reviewer and is therefore subjective. Furthermore, at Nebula Genomics we seek to educate the public about the benefits of Whole Genome Sequencing. Information about our Whole Genome Sequencing DNA test is therefore incorporated into the review.

GeneFood Introduction

GeneFood is a DNA upload and genetic analysis company that uses raw data to create a customized diet report. The company does not sell its own DNA test and customers must first have their DNA sequenced with 23andMe, AncestryDNA, or MyHeritage and upload the raw data file to GeneFood. The company may also accept DNA data from other companies, such as Nebula Genomics, that decodes your entire DNA. This ensures that the genetic variants GeneFood needs are included in the submission. 

Gene Food analyzes up to 120 genetic factors and a vast range of genes to help customers decide the type of diet that will work best for them. It compares your genetic profile to up to 21 diet plans, and after the analysis will show the user the particular diet or range of diet plans that they can go for to get the healthiest version of themselves.

It also provides information on a person’s nutrition and even suggests the intensity of exercises needed to sustain a healthy lifestyle.


Physician Dr. Steven Brody and health entrepreneur John O’Connor founded GeneFood as a wellness company that provides counseling and advice on nutrition to help people make healthy lifestyle choices. Over time, the company grew to include reporting based on genetic predispositions. It’s CLIA-certified laboratory is based in San Diego, California.

Gene Food previously sold a DNA test kit for $250. It would decode your DNA to generate the nutrition report. However, that test is sold out and the company does not appear to have plans to bring it back, focusing instead on users uploading previously sequenced DNA files.

Did you know that most genetic tests like GeneFood decode only 0.02% of your DNA? At Nebula Genomics, we offer affordable Whole Genome Sequencing! This is the most complete DNA test that decodes 100% of your DNA and will enable you to learn more about your ancestry, wellness, and health than any other DNA test! Click here to learn more!

The Science Behind GeneFood

GeneFood takes submitted DNA into a technologically advanced system algorithm that categorizes people’s genetic predisposition into one of the available twenty diet types. The company’s position is based on the idea that there is no “one size fits all” diet. Our unique genetic makeup plays a role in personalizing nutrition so that what works for one person may not work for another, despite having similar goals and body types. 

The company analyzes genetic markers that impact food by evaluating hundreds of peer-reviewed studies and ranking them on a science based scoring system called Science Grade. It weighs the most validated genes more heavily in the algorithm.

Also known as “DNA diets”, the field of nutrigenomics is growing. Unlike other genetic testing companies, GeneFood does not believe a single gene determines any health outcome, including nutrition. Thus, the company takes a comprehensive, inclusive approach by recommending a diet based on many genes. A summary of the most relevant genes to nutrition that have been strongly validated are available on the company’s website. 

It’s important to remember that the information provided in the reports is for informational purposes only. For specific medical questions, customers should consult their doctor.

Taking a GeneFood Test

Customers must first purchase and submit a DNA sample to another company such as 23andMe, Ancestry, or MyHeritageDNA to perform the nutrition analysis.

Once results are available, customers download the raw data files to their computer and can upload them using the contact form available on the GeneFood website. After that, the GeneFood Customized Nutrition Plan can be purchased. Results are ready in 5 minutes.

Review of GeneFood Customized Nutrition Plan

Review of GeneFood Cost

GeneFood Customized Nutrition Plan costs $79.99. While this price is reasonable given the comprehensive report, it is important to know that you first need to purchase a different genetic sequencing test to obtain your raw genetics.

Review of Gene Food Reports

The Gene Food report analyses different genes, SNP and alleles and attaches a Science Score to them. The Science Score shows the extent to which the particular gene, SNP, and allele affect nutrition.

The report can largely be broken down into three sections: 

  1. An overview
  2. Nutrition breakdown on things like fat, methylation, micronutrients, and sleep
  3. A detailed look at your genes

The overview describes the type of diet that best fits your genetics and gives you five food rules that will help guide your diet.

The next, and largest, section includes specific breakdowns on nutrition aspects such as fat, HDL:LDL ratio, sodium, sleep, blood sugar, NSAID tolerance, etc. It also indicates specifically food that works best for each diet. 

The sections will look different based on the aspect being described. Generally, each section will describe how your genes influence the aspect being described and in turn, how that affects your optimal nutrition uptake. Each subsection provides dietary recommendations and a meal plan based on the overall diet type. 

The final section is a detailed breakdown of your genes, including your genotype and the Science Score for each gene.

The scoring system is based on the level of validation each gene is assigned, which is a reflection of the strength of the association and evidence for that gene. Higher scoring genes are weighted more heavily in the algorithm used to recommend a diet type.

Review of GeneFood Privacy

GeneFood uses a secured encrypted connection to protect its client’s genetic data, one of their top priorities. The company also notes that it does not share or sell its client’s genetic data to a third party. The website and software are fully HIPAA compliant and SSL encrypted.

Other GeneFood Reviews

GeneFood has a 4.6 out of 5 stars on Trustpilot with 32 reviews. The score ranks very highly. However, the reviews talk about the amazing food, indicating that the reviewers may have mistaken the company for a restaurant of the same name. 

The company also shares some customer reviews on their website. As expected, the shared reviews are very positive, with many indicated that the service helped them lose weight. Customers found the reports helpful, interesting, and noted noticeable improvements in their health. They also had valuable interactions with customer support.

Pros and Cons


  • Comprehensive reports focused on personalized nutrition
  • Results within 5 minutes
  • Result is easy to interpret and accessible by the customer directly


  • Does not offer ancestry or health tests
  • Need for third-party DNA testing causes higher costs

Nebula Genomics

GeneFood provides one of the most comprehensive genetic reports that help users choose the right diet. A positive about those analyses is that it is extremely fast, and you can quickly get fitted into the diet plan that would help you achieve a healthy weight and other nutrition goals.

However, the fact that this genetic company is only focused on how genes affect a person’s diet, overall weight, and healthy lifestyle make it limited compared with similar reports that can also cover disease, traits, and ancestry. First, GeneFood does not sequence all genes, and even for the ones that are sequenced, they only provide information on their roles in helping people personalize their diet and nutrition. While the information provided is comprehensive for those specific genes, there are other testing companies that can expand on the whole genome, inclusive of the ones associated with nutrition. 

Therefore, a user would need a company that offers full genome sequencing to get better and deeper information on genetics’s roles in certain conditions that they are experiencing or are concerned they may experience.

Nebula Genomics offers 30x Whole-Genome Sequencing to provide full and accurate information on a person’s DNA. The testing method makes it one of the few standouts globally that provide extremely comprehensive analyses on a person’s entire genome. Plus, whole genome sequencing with Nebula is affordable. Sequencing 100% of your DNA costs $299 or less.

At this time, GeneFood only allows for the upload of DNA from other genetic testing sites. By sequencing your full genome with Nebula, you can submit the raw data (which always belongs to you) to GeneFood knowing that you have the information for this nutrition company to create the most focused diet plan for your needs.
