Could Coffee Really be GOOD for You?
My understanding of coffee's virtues was greatly enhanced by my interview withauthor of The Warrior Diet
and Unlocking the Muscle Gene
, who has researched coffee extensively. Ori explained how coffee, when consumed in the right way, can be used effectively as part of your overall health and fitness plan. Although organic coffee as a whole food may be therapeutic, caffeine in isolation can be quite toxic. The natural blend of polypheno(including chlorogenic acids), bioflavonoids, vitamins and minerals in coffee beans all work together to help neutralize the harsher effects of the caffeinThere are literally thousands of different natural chemical compounds in your brew, and science now suggests the synergy between them can pack a nice nutritional punch. With all of these compounds, you might wonder if there are any that have undesirable health effects. Yes, there are. But as I mentioned earlier, these are more concerning if ingested in isolation
, as opposed to being consumed as part of the whole food.
What about the Caffeine?
Caffeine is the most widely used drug in the world and can be helpful or harmful, depending on how it's used. Caffeine provides a "lift" by blocking the normal action of adenosine. Adenosine normally slows down your brain's activity and induces sleepiness. Some people are caffeine sensitive and don't tolerate it well, or have problems sleeping if they have caffeine too late in the day. Caffeine levels vary depending on type of bean, roast, grind, and brewing method. Contrary to popular belief, darker roasts typically contain less caffeine than lighter roasts due to the prolonged heat breaking down more of the caffeine molecules. Bean species also differ widely in their naturally occurring concentrations of caffeine. Additionally, drip coffee actually has more
caffeine than espresso because the brew time is much longer. And in general, the finer the grind, the higher the caffeine in the coffee. So, you might want to vary some of these factors if you experience a reaction, like switching from drip coffee to espresso, or changing brands. If you have an issue with decreased adrenal function, use coffee with care, as it can be hard on your adrenal glands. Coffee also has a diuretic effect, so if you have problems with electrolyte imbalance, you might want to avoid it. If you have any negative reactions to coffee, caffeine isn't always
the culprit. You could be sensitive to some of the burnt sugars or oils produced during the roasting of the beans, rather than the caffeine. People experience symptoms such as stomach cramping, heart palpitations and other autonomic symptoms, and these symptoms are usually interpreted as caffeine sensitivity when they are actually more of a food intolerance. There is also the possibility ofor othetriggering an allergy (as coffee is a dried food), so you want to make sure your coffee is of the highest quality and meticulously produced. But as a whole, if you're healthy, coffee is pretty well tolerated and the positive effects seem to outweigh the negative ones for most people. Please note that I still recommend women completely avoid using caffeine while
The List is Growing of Health Benefits from Coffee
The following is a summary of some of the more recent research that supports coffee's health benefits.

There are many more studies with positive findings—in fact, too many to list. Not every single study shows coffee to be beneficial, but the majority are quite positive, suggesting that coffee has been unfairly maligned. There is strong evidence coffee can help stabilize your blood glucose level and may even help cucravings. Caffeine binds to your opioid receptors, which essentially prohibits you from craving something else, such as sugar. Research also shows that coffee triggers a mechanism in your brain that releases a growth factor called Brain-Derived Neurotrophic Factor (BDNF). BDNF activates brain stem cells to convert into new neurons, and also expresses itself in your muscles. It does this by supporting the neuromotor, which is the most critical element in your muscle. Without the neuromotor, your muscle is like an engine without the ignition. Neuromotor degradation is part of the process underlying age-related muscle atrophy. Essentially, caffeine from natural whole coffee may help keep your brain and muscle tissue young.
When to Drink Coffee for Maximum Benefit
According to Ori Hofmekler's extensive research, coffee increases your metabolism by up to 20 percent. I've previously discussed the benefits of exercising on anBut coffee can actually be quite beneficial if consumed before exercise
. Ori states: "Coffee before training allows you fast energy to initiate your workout. For people who train in the morning, having coffee before training is a great advantage
." However, coffee is a potent substance and should be used only in moderation—without sugar
. Ori recommends having just one cup of organic coffee or one shot of espresso in the morning or before training, and that's it for the day. If you exercise in the morning, have your coffee prior to your workout, NOT after. Consuming coffee after your workout interferes with your body's muscle-building mechanism. Again, your body can handle
whole, fresh organic coffee because it doesn't hit your system the way synthetic caffeine does. But you don't want to go overboard.
Dark Roast Coffee may be Superior to Light Roast
When it comes to the health benefits of organic whole-bean black coffee, the darker the roast, the betteIt's often the case that foods with the darkest pigments also offer the most robust benefits to health, andsuch as French or Italian Roast, or roasts used to make espresso or Turkish coffee, are no exception. Roasted coffees are higher in neuroprotective agents than green (unroasted) coffees. A new study in Molecular Nutrition & Food Reseafound that dark roast coffee restored blood levels of the antioxidants vitamin E andmore effectively than light roast coffee. The dark roast also led to a significant body weight reduction in pre-obese volunteers, whereas the lighter roast did not. Other studies have shown that dark roast coffee produces more of a chemical called N-methylpyridinium, which helps prevent your stomach from producing excess acid, so darker roast coffee may be easier on your stomach than lighter roast coffee
Coffee Quality is Key: Four Tips to Remember
When it comes to achieving any therapeutic benefits from coffee, only quality coffee will do. You can find a great deal of information at Coffee & ConservatioHere are five primary considerations:
Choose Coffee beans are one of the most heavily sprayed crops with
pesticides. So, you should select only coffee beans that are certified organic. Remember, you will obliterate ANY positive effects if you consume coffee that's been doused in pesticides or other chemicals. Whenever possible, purchase sustainable "shade-grown" coffee to help prevent the continued destruction of our tropical rain forests and the birds that inhabit them. There are many who say shade grown coffee tastes better as well.
Whole Bean: You'll want to purchase whole bean coffee that smells and tastes
fresh, not stale; if your coffee does not have a pleasant aroma, it is likely rancid. Grind it yourself to prevent rancidity as pre-ground coffee may be rancid by the time you get it home.
Drink it Black: If you're interested in the health benefits, drink your coffee black,
without sugar or cream or flavorings. Add sugar and you'll certainly ruin any of the benefits discussed above by spiking your insulin levels, which contributes to Make sure theyou're using is pure.
Coffee Filters: If you use a "drip" coffee maker, be sure to use non-bleached
filters. The bright white ones are chlorine-bleached, and some of this chlorine will leach from the filter during the brewing process. Bleached filters are also notoriously full of dangerous disinfection byproducts, such as dioxin.
Coffee Mugs: Please be careful about the container you use. Avoid plastic cups as the
will leach into your drink, and also avoid Styrofoam cups that can leach
polystyrene molecules. Your best bets include glass and ceramic travel mugs.
