by Dr. Olisa Mak I have a guilty pleasure too. I love coffee, the smell of it, the bitter taste of it. Nothing wakes me up on a day off more than a fresh cup of dark roast coffee. I usually drink anywhere from 2-4 cups of coffee a week, but never more than one a day. Yesterday, I drank two cups of coffee, a latte that was quite strong and a dark roast two hours apart. The effect? A coffee overdose. For the rest of the day, I was restless, experienced chest pains, had chattering teeth, hands that were shaking, a headache and was unable to sleep. I was buzzed and overly stimulated. It wasn’t until 5am in the morning, roughly 14 hours after my second cup of coffee that I stopped feeling the buzz. Although, this morning, I woke up feeling completely hungover like I had a night out drinking. Although most people do not experience such an extreme reaction, it isn’t uncommon to hear people say that they can’t handle coffee, that they feel “jittery”. On the other end of the spectrum, there are people who simply do not feel anything after drinking coffee. So what does all of that mean? Why do some people, like myself, have such extreme reactions to coffee whereas some people feel nothing? First we have to understand how coffee is metabolized in the body. When we drink coffee, it reaches our digestive tract where the coffee is modified and individual chemical constituents of coffee are absorbed by our small intestines. Once in the small intestines, the various chemical compounds found in coffee are absorbed and circulate throughout the bloodstream and reach the liver and other organs. The liver metabolizes coffee in a stepwise manner and in each step, the compounds are chemically modified to become more and more water-soluble, to ensure proper elimination by the kidneys and bowels. There are two general steps in the liver detoxification process - Phase 1 and Phase 2. When you’re overly sensitive to coffee, your phase 1 is sluggish whereas if you don’t feel anything from coffee, your Phase 1 is too active. So how can you bring these two steps back into balance? If you’re overly sensitive to coffee, you need to give your Phase 1 a boost. Phase 1 relies mainly on B vitamins (amongst other nutrients) whereas Phase 2 mainly relies on amino acids from protein sources like good quality meats. A diet abundant in colourful fruits and vegetables, rich in vitamins is key. There are also supplements that have been especially formulated to support liver function when changing your diet isn’t enough. Certain foods, especially cruciferous vegetables like kale, cabbage, broccoli and brussels sprouts, are also great for giving Phase 1 a boost. If your Phase 1 is overactive and you don’t feel anything from coffee, then you need to slow down Phase 1 and herbs such as Calendula officinalis or spices such as turmeric are great. Other than feeling “jittery” after drinking coffee, why is it important to correct an imbalance between Phase 1 and Phase 2? At the end of Phase 1, reactive oxygen species are produced. If Phase 1 is overactive or faster than Phase 2 pathway, you ultimately get an accumulation of reactive oxygen species because your Phase 2 just can’t keep up with Phase 1. Reactive oxygen species are chemically reactive molecules known to cause inflammation and damage throughout the body, including cellular DNA damage. Reactive oxygen species or high oxidative stress have been implicated in chronic conditions including cancer, diabetes, atherosclerosis and aging, Having signs of an imbalance between Phase 1 and Phase 2 has long term consequences and should be addressed. Figure 1. Your liver and Phase 1 and Phase 2. Although the body naturally produces reactive oxygen species, the body has protective mechanisms in place to protect itself. By eating a diet rich in antioxidants such vitamin C, zinc and thiols which can be found in garlic, onions and cruciferous vegetables, the body neutralizes these harmful, reactive oxygen species.
The balance between Phase 1 and Phase 2 is important to understand as it plays a key role in the metabolism of everything that our bodies comes into contact with - not just coffee but alcohol, medications, supplements, pesticides on our foods, even chemicals we absorb through our skin from personal health care products. The rate at which Phase 1 and Phase 2 function ultimately defines how well our liver protects us from everything that we are exposed to. The chronic illnesses associated with high oxidative stress or reactive oxygen species may not appear right away but ultimately affect our ability to live healthy and happy lives. Love your liver by eating a well-balanced, organic diet, rich in antioxidants and nutrients. My ordeal from drinking only two cups of coffee brought to my attention the imbalance between my liver’s Phase 1 and Phase 2. I too, will examine my diet and find a way to improve my liver’s functioning. Will you?

So according to your logic, if I am very intolerant to caffeine, it could be i have imbalance, and phase 1 is too active....as I do eat tons of broccoli and other crucifers, everyday. A big bowl of steamed broccoli a day. And I don't eat a lot of protein at all. So, maybe I should be eating more lean protein (fish?) and reduce the broccoli intake for now? Thanks for any more guidance.
