Gene Food reviews

If the past year has brought you struggles with nutrition or weight management, you’re not alone. Effects of the pandemic, quarantines, and virtual schooling have only increased America’s staggering 42% obesity rate. But finding an appropriate diet that works can be challenging. High protein diets work for some but make others sick. How do you know the best regimen for you?

And while the effectiveness of these diets is debated, their popularity continues to skyrocket.

We investigated Gene Food, one of the newest companies offering a genetic analysis to provide you with personalized diet and lifestyle suggestions for better health. Could Gene Food be your solution?

What is Gene Food?

Founded in 2016 by health entrepreneur John O’Connor and San Francisco physician Dr. Steven Brody, Gene Food is a health and wellness company providing dietary and nutritional advice based on DNA analysis. You can purchase a DNA test from Gene Food and send it to its CLIA-certified lab for analysis, or you can send in raw DNA data from 23andMe or

Gene Food’s team of researchers, led by head geneticist Dr. Aaron Gardner, takes your DNA and feeds it into a proprietary algorithm that categorizes your genetic predisposition into one of 20 diet types. Unlike companies that analyze only a handful of genetic factors, Gene Food examines over 120 to determine your ideal diet type. Below, you’ll find several of the factors that Gene Food takes into its analysis and nutrition report.

Gene Food asserts that DNA analysis plays a useful role in helping you choose a diet plan by identifying how your body responds to fat, carbs, caffeine, and other nutrients. Additionally, Gene Food advises its customers about predispositions for coronary heart disease and other issues and informs them of foods to choose and avoid to lower risks.

If you keep in mind that genetics make up only one portion of what you should consider when developing a personal nutrition plan, we believe that assertion to be valid.

How does it work?

The term “nutrigenomics,” first coined in 2001, is a science that studies the relationship between health, nutrition, and the human genome. Nutrigenomics today has developed into a quickly expanding health and wellness market aimed at helping customers attain better nutrition and dietary management through an analysis of their DNA. It may sound preposterous, but if you look at traits within your own family, you’ll likely see several inheritable characteristics passed through generations. The same applies if you look at your ethnological heritage.

Gene Food requires a sample of your DNA, either from a swab that you send to its lab or from raw data that you submit; this latter method is an option if you’ve tested with or 23andMe.

Then Gene Foods analyzes multiple genes related to nutrient absorption and overall health and presents you with a report detailing the best diet for your particular genome. In the end, the company categorizes your needs into one of its 20 diets and presents a detailed analysis of how your body reacts to certain foods.

Is Gene Food legit?

It’s important to remember – and Gene Food is clear in cautioning on its website – that DNA is only one factor in personalized nutrition regimens. Some in the scientific community argue that genetics play a minor role in dietary success. Keep in mind that factors like stress, anxiety, abnormal sleep patterns, illness, and others play a critical role in your health and wellness as well. However, Gene Food can give you insight into how much your genetic predisposition may affect your relationship with food, weight management, and overall health. When optimizing your nutritional approach, every angle is valuable.

What’s inside your Gene Food report?

Your full report from Gene Food covers many genetic factors affecting your diet. The report gives you feedback on foods you should avoid due to specific genes and others that you should embrace. Below are just a few of the primary areas of the report and what they reveal:

  • Sodium: This section of the report examines how your body processes sodium and gives feedback on how sodium levels affect nerve and muscle function.
  • Sleep: Gene Food gives feedback on DNA factors that may affect your sleep and offers insights on improving your sleep health.
  • Caffeine and Alcohol: Have you wondered how your particular genome metabolizes caffeine and alcohol? This section gives feedback on how much of each you should consume.
  • Cannabis: Gene Food is currently the only nutrigenomics company out there that gives insights on your genetic predisposition for processing cannabis and suggestions for consumption amounts.
  • Blood Sugar: This analysis determines what types of carbohydrates are most appropriate for your diet.
  • Plant Protein: You can gain information about what percentage of protein you should be getting from plant sources.
  • Protein Metabolism: This section explains how your body reacts to dairy, histamine, and plant proteins.
  • Macronutrients: This area explains the best fat to carbs ratio for your personal diet.
  • Supplements: Gene Food offers suggestions for vitamins and supplements you might be lacking based on your DNA profile.
  • Detox: This part of the report looks at how your body processes environmental toxins.
  • All About Fat: In this section, you’ll find information on fat metabolism and HDL to LDL ratios (good cholesterol vs. bad cholesterol). The report explains how these levels relate to your DNA and what fats should be avoided.

Gene Food assigns you one of 20 different diet types tailored to genetic traits based on your DNA analysis. These diets include:

California Keto, Urban Grazer, Mosaic, Paleo Plus, Modified Paleo, Trainer, Pegan, Pescetarian, Agrarian, Nordic, Mediterranean, Hunter Gatherer, Forager, California Coastal, Vegetarian, Okinawan, Villager, Lean Machine, Wayoan, West Angelino

For instance, one of our testers’ reports advised that the Mediterranean diet was ideal for her. This diet is characterized by high vegetable, whole grain, fruit, and nut consumption; moderate protein consumption with a focus on fish and seafood; and using olive oil. While the Mediterranean diet has been advised for broad swaths of the population by nutritionists, this report from Gene Foods detailed reasons why the diet was appropriate for our tester based on her genetic data. For instance, she lacked celiac or gluten sensitivity, meaning that the Mediterranean diet’s incorporation of good quality bread was not an issue (which she embraced).

The report details your diet’s main components (low-carb, low protein, etc.), what foods should predominate your daily food intake, and suggestions for lifestyle changes to improve wellness. It also includes a recommended shopping list and recipes to get you started on your health journey.

Pricing and products

Unlike some nutrigenomics companies, Gene Food sells its products on a one-off basis without ongoing subscription costs. In addition to your detailed personalized diet plan, you’ll have access to the Nutrigenic Health Coaching service, which costs $175 per hour. We’ve detailed Gene Food’s two products below.

Gene Food DNA Test

$185 but currently selling for $165

If you do not have access to raw DNA data from 23andMe or, Gene Food now offers a DNA kit of its own. You simply order a test kit, provide a saliva sample, and return it to Gene Food’s CLIA-certified, HIPAA-compliant genetics lab in San Diego. The advantage of submitting a DNA kit from Gene Food is that it offers more coverage for the genes used to calculate your score. The plan’s two drawbacks are the higher cost and the longer turnaround time to get your results.

Your report with the Gene Food DNA Test is the same as a report for the raw data submission, except that some “bonus genes” may appear in your analysis. Gene Food lays out your recommended personalized diet and foods that may interfere with your health. It examines your genes related to protein, fat, and carbohydrate metabolism, the MTHFR gene, sulfur, histamine, lactose tolerance, and wheat tolerance, among others.

Custom Nutrition Plan for 23andMe and Users

$95 but currently selling for $79.99

If you have previously submitted a DNA sample to 23andMe or, you can access your raw data through those sites and submit it to Gene Food for analysis. This method of submission is fast, with results returned to you in just five minutes.

Your full report includes your recommended diet type and nutrition plan, along with a detailed examination of the meaning behind each finding.
