Why are the captions in the thumbs back? Facebook won't allow replacing the preview picture of links easily. Don't worry, not all news in 2020 is bad news... unfortunately, though, there's some 'bad coffee news' out there, too. In the following overview, I am going to cover a bunch of interesting studies - good and bad news, just as you'd see them in the ever-more non-scientific apocalypse that we live in. Enough said, here's what I've found being published from late September to early October 2020: You can learn more about coffee and caffeine at the SuppVersity For Caffeine, Timing Matters! 45 Min or More?

Hot News About Cold Tea: Cold Maté Tea Increases Energy Expenditure 2x More than Hot Maté | No Strings Attached?

Written by | published on

I don't want to spoil your beloved maté tea for you, but if you expect it to shed slabs of body fat off your frame, this belief may well spoil your fat loss efforts for you ;-) I've previously addressed the potential benefits of cold-brewing your coffee  and the effect of water temperature on the extraction of bioactive substances from coffee in my "Coffee 101" ( Moussa 2017 ). For (caffeinated) tea, I haven't done this yet... what I haven't done for either of the two is to address the effect of the beverages' temperature at consumption. In their latest RCT, Maufrais et al. ( 2018 ) did just that... more specifically, they "compare[d] the cardiovascular, metabolic and cutaneous responses to the ingestion of [Yerba Mate] at cold or hot temperature in healthy young subjects."

May I Salt & Roast My Nuts? Plus: If Catechins Boost One's Energy Expenditure by 400% Why Don't They Work for Me?

Written by | published on

One article, two questions, two science-based answers. If you're like me I bet that you've been asking yourself previously, whether the cheap roasted nuts at the supermarket have the same health benefits as the expensive "raw" nuts from the health-food store... guess what: a recent study by scientists from the Singapore Institute for Clinical Sciences  and the University of Otago  confirms: "Dry roasting and lightly salting nuts do[es] not appear to negate the cardioprotective effects observed with raw nut consumption, and both forms of nuts are resistant to [dietary] monotony" and thus similarly recommendable health-foods. Along with the latest "green tea for thermogenesis"-study, which finally answers the important question "If Catechins Boost One's Energy Expenditure by 400% Why Don't They Work for Me?", the Chinese-New-Zealand co-production is one of the two studies in today's SuppVersity article.

Theanine + Caffeine - A Natural and Powerful Combination to Increase Your Attention and Reaction Speed (+6-10%)

Written by | published on
Image
Tea will naturally contain both theanine and caffeine, but will it work, as well as supplemental theanine and caffeine? While everybody knows caffeine (see last SV article comparing caffeine to coffee ), theanine aka L-γ-glutamylethylamide or N5-ethyl-L-glutamine, an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine, is less well known, but as a recent study shows not less potent when it comes to its effects on cognition and neurophysiological measures of selective attention aka "focus" on a task / object (Kahathuduwa. 2016). You want to know why the researchers from the Universities of Peradeniya, Kelaniya  and the Texas Tech University  know that? Let's take a look at what the researchers did and why they conclude that the effects of caffeine & theanine add up.

Fat-Blocker Effect of Tea Catechins Confirmed (?) in Man - Sign. Abdominal Fat Loss (5-8%) in 12 Weeks W/Out Diet

Written by | published on

Tea catechins (which can also be found in black and jasmin tea | see Figure 3 ) can help you keep particularly unhealthy abdominal fat (Després. 2012) at bay. It is one thing to have in-vitro and rodent data that green tea can inhibit the digestion of dietary fat (reported previously in the SuppVersity Facebook News ); it is another thing, however, to have a human study like the one Makoto Kobayashi and colleagues are about to publish in the peer-reviewed scientific journal Food & Function  that shows that the "[i]ngestion of a green tea beverage enriched with catechins with a galloyl moiety (THEA-FLAN 90S) during a high-fat meal reduces body fat in moderately obese adults" (Kobayashi. 2015). Ok, the abdominal fat loss does not, as the previous quote from the conclusion appears to suggest, occur instantly right after you've consumed your first tea w/ a single meal.
