Our body works according to a biological instruction manual, and knowing your DNA metabolism is the key to understanding it.
The differences in our digestions and reactions are often due to a genetic intolerance. Today we are going to explore how certain genes dictate your daily well-being and why taking a DNA test like the one from tellmeGen can mark a before and after in your quality of life.
The secret to your metabolism lies in your genetics
For years we have blamed stress, age, or bad luck for our heavy digestions. However, science has shown that the real culprit is usually hidden in the structure of our cells.
Nutrigenetics is the science that studies how our genes interact with what we eat and drink. Analyzing this information allows us to leave assumptions behind and start adapting our diet in a 100% intelligent and personalized way.
Caffeine and the CYP1A2 gene: Are you a fast or slow metabolizer?
If you are one of those who cannot have a coffee after eating, the CYP1A2 gene has the perfect explanation. This gene encodes the liver enzyme responsible for clearing and breaking down caffeine in your body.
- Fast metabolizers: They eliminate caffeine at high speed. They can enjoy a cup in the afternoon or evening without their sleep cycles being altered.
- Slow metabolizers: Their enzyme works at a reduced rate. Caffeine stays in the system for hours, causing nervousness, tachycardia, and trouble sleeping
Alcohol and the ALDH2 gene: The science behind the hangover
Do you know the real genetic causes of a hangover? When you consume alcoholic beverages, your liver transforms them into acetaldehyde, a very harmful toxin. This is where the ALDH2 gene comes into play.
- Efficient variant: It quickly transforms the toxin into a harmless substance called acetic acid, allowing you to better tolerate moderate consumption.
- Inefficient variant (mutation): The body accumulates the toxin all at once. This generates the typical facial flushing, severe nausea, and a very low tolerance to alcohol, guaranteeing much worse hangovers.
Lactose and the LCT gene: Your digestions exposed
The ability to digest breast milk at birth is universal, but maintaining it into adulthood depends exclusively on the LCT gene. This gene is in charge of giving the instructions to continue producing the lactase enzyme in the gut.
- Lactase persistence: Your body continues to produce the enzyme and you can consume cheese, milk, and yogurt without suffering any intestinal problems.
- Non-persistence (Lactose intolerance): Your lactase production drops drastically. If you consume dairy, you will experience bloating, gas, and severe abdominal pain.
Leaving your health and nutrition to chance no longer makes any sense in the 21st century. Today, investing in health is one of the best direct investments in your long-term well-being. You no longer need to keep experimenting with diets that make you feel bad.
