Coffee. Is it good or is it bad! The Verdict.

Coffee. Is it good or is it bad! The Verdict.

It is an age-old question. Is coffee good or is it bad for you. Well the answer is absolutely locked within your genes. Genetic advances have made it now common place to explore the secrets within your genetic make-up. Revealing whether coffee is good or bad for you is one of the nuggets of information that can be discovered.
Coffee is the world’s most popular drink and many people rely on its bitter tasting buzz to get through their day. However, it is not actually the coffee part that makes us doubt whether the drink is healthy or not for us, it is the caffeine.

Coffee is one of the most nutrient dense drinks on the planet, offering amazing phytonutrients and flavonoids that are exceptional for supporting good health. There you have it, coffee is amazing for health. It is not that simple, I am afraid. The wonderful coffee plant evolved eons ago in response to a bug attack. To counteract it being devoured constantly by bugs the coffee plant evolved to produce a neurotoxic bug killer that we today call caffeine. Tea did the same!

Caffeine is a neurotoxic agent and can be deadly if you are an insect. However, us, much larger, humans, caffeine is not deadly, but offers us a neuro buzz. Caffeine, as a neurotoxic agent, is not great for health at all. Not only does it play around with our nervous systems chemical signalling, it can linger in the cardiovascular system and cause inflammation. Inflammation in the blood vessels is not good, that’s the first stage of plaque formation. Caffeine will also stop you making new, fresh strands of collagen, so if beauty is important to you, don’t be fooled with face products that promote caffeine. It just draws the blood to the surface to promote a nice complexion for a bit, but it will absolutely interfere with your collagen production. So now coffee is really sounding bad.

So how do our genes determine whether it is a healthy super food or just a detrimental health demon. It comes down to the gene and enzyme, CYP1A2. This natural enzyme in our body is responsible for breaking down many things and caffeine is amongst its workload. We are all made differently, and variations of this gene means that some people have a super-fast action of this enzyme and some people, the enzyme works extremely slowly. It is this variation that determines whether coffee is beneficial or detrimental to your health.

Those that have a super-fast CYP1A2 enzyme can break caffeine down quickly. They are often the people that can drink a cup before bed and still sleep. As it is broken down fast, it isn’t lingering in the body for long enough to be too problematic and you are left with that glorious phytonutrient rich soup for all of its incredible health benefits. Well, that’s if you don’t start adding lots of dairy, sugar or syrups to it!

On the other hand, if you have a sluggish CYP1A2 enzyme, you are not going to be brilliant at clearing the caffeine and therefore it will linger in your skin and age you or help to inflame your cardiovascular system. It will certainly give you a crazy buzz that may last throughout the day.

So, there you have it. Coffee is good for some people, but bad for others. If you love your coffee, or tea and want to protect your health then it is certainly worth exploring a lifestyle genetic test.

And just a little note on decaffeinated. This is absolutely a more protective option for those with slow CYP1A2, but the process to decaffeinate the drinks does lead to loss of some of that amazing nutrition. So I am afraid there is no win-win situation here, for you coffee lovers with a slow CYP1A2.
