Coffee is one of the most chemically treated foods in the world (global demand is high, so methods of growing it often are chemical fertilizer-pesticide-herbicide intensive). This is bad for you (since pesticide residues can end up in your cup) and really bad for the planet. High demand and the fact that it’s generally grown in poorer countries also means labor practices are a major issue. Buy organic and fair-trade if and when you can.
I also tried his Bulletproof Coffee which is much smoother than regular coffee and which he claims is produced carefully to avoid the presence of mycotoxins: “Most coffee beans are processed by either leaving them in the sun and elements to wither and dry, or by pressing them and letting them ferment (spoil) to remove the outer layer of the bean. Both of these techniques are known to produce significant levels of mycotoxins as they enhance flavor. Upgraded coffee beans are mechanically processed right after picking using only clean cold water. This more expensive process is safer because it dramatically reduces harmful molds or bacteria from impacting your health.”
Other than that, antioxidants play a significant role in neutralising free radicals that naturally occur as a part of daily metabolic functions. However, the radicals in question are those that can cause oxidative stress and not the useful type. In other words, the antioxidants in a steaming cup of coffee can go a long way in keeping you healthy at a micro-level. And they do so by protecting your cells from any possible external physical damage.
5-HIA, an organic acid and component of the neurotransmitter serotonin (the happy chemical) seen in the urine tends to be elevated in coffee drinkers, which means they may be at risk for lower levels of serotonin synthesis in the brain. Serotonin is necessary for normal sleep, bowel function, mood, and energy levels. It is a vicious cycle, as caffeine can disrupt sleep and promote anxiety and depression. We all know someone who tends to be tired, wired and over-caffeinated!
After one too many long nights at the office, it’s not uncommon to experience mental fatigue. In addition to getting your mental health back on track to make sure it doesn’t lead to more serious health problems, drink some coffee: A 2010 review in the journal Nutrition found caffeine can help decrease the exhaustion you’re feeling by perking your body up.

If you are already a coffee drinker, it should be reassuring that after decades of research, no strong link can be found between coffee intake and cancer and, to the contrary, a number of health benefits seem to accompany coffee consumption. But, I’m not sure the evidence is powerful enough to recommend an increase in your daily habit. One reason is that we don’t know for sure that coffee consumption actually caused the health benefits observed in these studies. Some other, unmeasured factor could be responsible. Another reason is that the overall effect was small. And, it’s worth noting that some people are quite sensitive to the side effects of coffee.
More recently, Australian researchers looked at 18 studies of nearly 458,000 people. They found a 7% drop in the odds of having type 2 diabetes for every additional cup of coffee drunk daily. There were similar risk reductions for decaf coffee drinkers and tea drinkers. But the researchers cautioned that data from some of the smaller studies they reviewed may be less reliable. So it's possible that they overestimated the strength of the link between heavy coffee drinking and diabetes.
In a 2007 study published in the International Journal of Dermatology, researchers found caffeine could be a potential hair growth stimulant for men with androgenetic alopecia, a common type of hair loss. In fact, the growth of the hair follicles that were treated with caffeine increased 46 percent and the life cycle of the hair was extended by 37 percent. And once you’re hair is luscious and flowing, here’s the Haircut That Will Shave 10 Years Off Your Age.
You probably think of coffee as a pick-me-up. But its effects don’t kick in for about 30 minutes. That means if you enjoy a cup of coffee just before taking a 20-30 minute nap, you may wake up feeling extra-energized. Just be sure you don't try this hack too late in the afternoon; it's best to stop consuming caffeine six hours before you hit the hay.
