Red Meat and Cancer? Not if You Protect Yourself With Coffee. A Cup of Coffee With / After Meals Will Do the Trick

Real coffee, real benefits - Filter coffee, but not instant will do the trick
While this is not directly related to the MDA issue, it is still intriguing that past studies on the role of coffee consumption in the etiology of gastric cancer are highly inconclusive. While studies conducted in the US and Europe have shown hardly relevant increases (US) and decreases (EU) in gastric cancer risk with high vs. low coffee intake, data from South America suggests that coffee consumption reduces the incidence of gastric cancer by 46% (Botelho. 2006). Without understanding the underlying effects the consumption of coffee has on both, the gastrointestinal tract and the stuff that comes into our system via that route, it is however difficult to come up with potential explanations for this discrepancy; and this is where the observations Sirota et al. made could actually come handy.
While green bean enriched coffee is slightly more potent, regular ground coffee does suffice
|Green coffee beans suppements which contain up to 80% polyphenols of which∼50% are CGAs can be used as an alternative to coffee from ground roasted bean and may also help you burn body fat (read more)|
And while it is important to note that green coffee bean powders and extracts could be an alternative (see image on the right) for all of you who are not into drinking coffee, the instant and most probably even the standard "pad coffees" are no suitable alternative to the ground coffee beans used in this study, because their MDA inhibitory effect on muscle food lipid peroxidation is 2-5x lower than that of a cup of coffee from ground roasted beans.
|Did you know that Coffee is also a testosterone booster? In this case it does yet appear as if the major player is caffeine, which probably does not play a role as far as the anti-MDA effects in the study at hand are concerned (learn more).|
So thumbs up for the post-meat-meal-coffee, right?
"[...] results seem to be of great importance for further investigations on the involvement of dietary polyphenols and other antioxidants in human health." (Sirota. 2013)Moreover, their study appears to support their hypothesis that "coffee, the most popular beverage in the world, supplies the most significant portion of daily in-take of dietary antioxidants" (Sirota. 2013) - a contribution that's significant enough to "effectively control lipid peroxidation in the stomach medium and thus prevent post-prandial absorption and plasma MDA modification" (Sirota. 2013).
And the researchers even have a very concrete advice for you: Time your coffee intake so that you get it either the Italian way, right after, or as in their study right with a potential high MDA meal. Ok, I got to admit this is no exact quotation any longer, but basically it is what they wrote. Plus, this way it spares me to write an extra "bottom line" to which I just have to add that taking up drinking coffee (or tea) if you don't like it is not mandatory to survive meat consumption and that people who suffer from low iron levels should keep in mind that the coffee and tea (and other) phenols will inhibit the absorption of heme- and even more non-heme iron.
