Folate Metabolism: Variations in the MTHFR gene can influence the efficiency of folate metabolism. Individuals with certain variations may require higher levels of dietary folate or supplementation to ensure adequate nutrient intake.
Omega-3 Fatty Acids: Genetic variations in the FADS gene have been shown to impact the metabolism and utilization of omega-3 fatty acids. Individuals with specific variants may benefit from higher intake of omega-3 fatty acids or supplementation to support cardiovascular health.
Caffeine Metabolism: Genetic variations in the CYP1A2 gene influence the rate at which caffeine is metabolized. Individuals with variants associated with slower caffeine metabolism may be more susceptible to the negative effects of caffeine, such as increased heart rate or disrupted sleep.
Sodium Sensitivity: Genetic variations in genes involved in sodium metabolism, such as ACE and AGT, can influence an individual’s sensitivity to sodium intake. Individuals with certain variants may benefit from reducing their sodium intake to manage blood pressure levels.
By understanding these illustrative examples of nutrient gene interactions, we can appreciate the impact of genetic variations on nutrient responses and tailor dietary recommendations to better suit individual needs.
