Genetics plays a huge role in how well you convert the carotenes into retinol. Some people are great at converting beta-carotene in their diet into the retinol form. Others carry genetic variants that significantly impair that conversion.
There are several genes that can influence your absorption, transport, and need for vitamin B12. Some people need higher amounts of B12, and some people thrive on different forms of B12. Take a look at your genetic data to see if you should up your intake of B12.
Our ancient ancestors lived much differently than we do today. They were hunter-gatherers, living off of fish, meat, and plant foods that they gathered. A huge shift took place when those hunter-gatherers began farming, growing grains and storing them so that there would be food available all year. Learn if you carry the hunter- gatherer or farmer gene variant.
Chronic headaches, sinus drainage, itchy hives, problems staying asleep, and heartburn -- all of these symptoms can be caused by the body not breaking down histamine very well. Your genetic variants could be causing you to be more sensitive to foods high in histamine. Check your genetic data to see if this could be at the root of your symptoms.
Mushrooms contain a healthy antioxidant called ergothioneine. But for people with a OCTN1 genetic variant, this antioxidant can be too much of a good thing, leading to intestinal problems. Check your genetic data to see if you carry this mushroom intolerance variant.
This article digs into the high quality research on the common CBS genetic variants to determine if there is any evidence suggesting everyone should be on a low-sulfur diet. Read through the research and check your genetic data.
For some people, stacking caffeine with carbohydrates will raise their blood glucose levels more than just carbs alone. Learn whether you carry this genetic combo and what to do about it.
We all vary in how well we convert the plant-based omega-3 oils into the DHA and EPA that our body needs. Some people are really poor at this conversion and thus should either eat more fish or consider taking a DHA / EPA supplement.
Foods high in tyramine can cause a hypertensive crisis for people on MAOA inhibitors - and possibly for people who genetically have impaired tyramine metabolism. Learn more about the foods high in this biogenic amine and check to see if you carry the genetic variants that put you at risk.
