In this episode, I chat to genetics expert Emma Beswick about how foods affect our genes and how, in return, genetic variations affect the way we react to nutrients in foods. We cover their influence on the day-to-day of who we are and how we function, including our hormones, brain chemistry, and immune system. It’s a must for anyone who loves going that little bit deeper into things, and it’s a great way to showcase how stunning the human body is!

TAKEAWAYs

✔️ Nutrigenomics Explained:

Nutrigenomics studies how foods interact with our genes and vice versa.
Genetic variations (snips/SNPs) affect how individuals respond to nutrients, hormones, and environmental factors.
While we can’t change our DNA, we can influence how our genes are expressed through diet, lifestyle, and environment.

✔️ Genes vs. SNPs (Snips):

Gene: A segment of DNA coding for a protein that performs a function in the body.
SNP (Single Nucleotide Polymorphism): A tiny variation (change of one letter) within a gene that can alter how well it functions.
Understanding these differences helps tailor diet and lifestyle choices.

✔️ Practical Genetic Applications:

Genetic testing can clarify why some nutritional or lifestyle approaches work for some people but not others.
Bite-sized genetic panels from Life Code GX provide actionable results instead of overwhelming raw data.
Example: Lactose digestion varies by gene; testing can explain digestive issues with milk or dairy products

✔️ Hormones & Female Health:

Genes influence hormone metabolism, sensitivity, and detoxification (e.g., estrogen).
Estrogen-related genes affect conditions such as PMT, menopause symptoms, and choline production.
Nutrition can support gene function, e.g., choline-rich foods like eggs and fish improve brain health and pregnancy outcomes.

✔️ Folate & Methylation:

Folate is critical for methylation, a key process for detoxifying hormones and producing neurotransmitters.
MTHFR gene variations affect folate activation. Overuse of synthetic folic acid may overwhelm certain pathways.
Personalized advice ensures optimal intake without overloading the system.

✔️ Empowerment, Not Alarm:

Genes are information, not destiny.
Genetic insights provide actionable steps to optimize health and prevent issues, rather than dictate fate.
Working with trained practitioners ensures genetic results are interpreted safely and effectively.
