What Is Nutrigenomics?

Nutrigenomics is the science of how genes interact with nutrition. It explains why the same diet can have different effects on different children — one child might thrive on a high-protein diet while another gains more benefit from complex carbohydrates.

At GenExcel, we analyze 80+ nutrition-related genetic markers to create a truly personalized dietary roadmap for your child.

How Genes Affect Nutrition

Your child's DNA influences several key nutritional processes:

1. Vitamin Absorption

Variations in genes like MTHFR affect how efficiently the body converts folate (vitamin B9) into its active form. Children with certain MTHFR variants may need higher folate intake or specific supplementation to support brain development and cell growth.

Similarly, GC gene variants influence vitamin D metabolism. Some children are genetically predisposed to lower vitamin D levels, making supplementation essential — especially in regions with limited sunlight.

2. Lactose and Gluten Sensitivity

The LCT gene determines whether a child maintains the ability to digest lactose after infancy. Genetic testing can identify lactose intolerance risk before symptoms appear, allowing parents to adjust dairy intake proactively.

Genes in the HLA region indicate predisposition to celiac disease and gluten sensitivity. Early detection means early dietary adjustment.

3. Fat Metabolism

The FTO gene (often called the "obesity gene") influences appetite regulation and fat storage. Children with certain FTO variants may benefit from:

Higher protein meals to maintain satiety
Structured meal timing to regulate hunger hormones
Specific types of physical activity to optimize metabolism

4. Micronutrient Needs

Genetic variants affect the metabolism of iron (HFE gene), omega-3 fatty acids (FADS1/FADS2), caffeine sensitivity (CYP1A2), and antioxidant processing (SOD2). Understanding these helps parents provide precisely what their child's body needs.

Real-World Example

Consider two 8-year-old children eating identical school lunches:

Child A (with FTO risk variant + low FADS2 efficiency): Needs more omega-3 rich foods, benefits from smaller frequent meals, and may need iron supplementation
Child B (with efficient MTHFR + high LCT activity): Thrives with standard dairy intake, processes folate efficiently from leafy greens, and has normal iron absorption

Same meal, very different nutritional outcomes. That's the power of nutrigenomics.

GenExcel's Nutrigenomics Report

Our comprehensive nutrigenomics analysis includes:

Macronutrient balance — optimal protein, carb, and fat ratios for your child
Vitamin & mineral needs — personalized supplementation guidance
Food sensitivity alerts — lactose, gluten, caffeine, and more
Metabolism profile — how your child processes fats, sugars, and proteins
Meal recommendations — practical, age-appropriate food suggestions

AI NutriScan: Genomics Meets Daily Meals

GenExcel's AI NutriScan feature takes nutrigenomics from theory to practice. Simply snap a photo of your child's meal, and our AI analyzes the nutritional content against your child's genetic profile — giving real-time feedback on whether the meal meets their unique needs.

The Future of Feeding Your Child

Nutrigenomics transforms nutrition from guesswork into precision science. Instead of following generic dietary guidelines, parents can now provide exactly what their child's body is designed to thrive on — backed by DNA.
