'Green tea consumption is associated with lower psychological distress in a', The American journal of clinical nutrition

'We classified 2774 (6.6%) of the respondents as having psychological distress (Kessler 6-item psychological distress scale > or =13/24). There was an inverse association between green tea consumption and psychological distress in a model adjusted for age and sex. Although the relation was largely attenuated when possible confounding factors were adjusted for, a statistically significant inverse association remained. The odds ratio (with 95% CI) of developing psychological distress among respondents who consumed >/=5 cups of green tea/d was 0.80 (0.70, 0.91) compared with those who consumed <1 cup/d. These relations persisted when respondents were stratified by social support subgroups or by activities in communities.' -- p1393, col 2, para 1

'We classified 2774 (6.6%) of the respondents as having psychological distress (Kessler 6-item psychological distress scale > or =13/24). There was an inverse association between green tea consumption and psychological distress in a model adjusted for age and sex. Although the relation was largely attenuated when possible confounding factors were adjusted for, a statistically significant inverse association remained. The odds ratio (with 95% CI) of developing psychological distress among respondents who consumed >/=5 cups of green tea/d was 0.80 (0.70, 0.91) compared with those who consumed <1 cup/d. These relations persisted when respondents were stratified by social support subgroups or by activities in communities.' -- p1393, col 2, para 1

' In acute studies, EGCG (1-100 microM) elicited dose-dependent vasodilation in mesenteric vascular beds (MVB) isolated from SHR ex vivo that was inhibitable by N(omega)-nitro-L-arginine methyl ester (L-NAME; nitric oxide synthase antagonist) or wortmannin [phosphatidylinositol (PI) 3-kinase inhibitor]. In chronic studies vasodilator actions of insulin were significantly improved in MVB from EGCG- or enalapril-treated SHR (when compared with vehicle-treated SHR). Both EGCG and enalapril therapy significantly lowered systolic blood pressure (SBP) in SHR. EGCG therapy of SHR significantly reduced infarct size and improved cardiac function in Langendorff-perfused hearts exposed to ischemia-reperfusion (I/R) injury. In SHR given L-NAME, beneficial effects of EGCG on SBP and I/R were not observed. Both enalapril and EGCG treatment of SHR improved insulin sensitivity and raised plasma adiponectin levels.

Likewise, 10 microM of pEGCG was effective in reducing caspase-3 activity, while EGCG at all concentrations tested in the model failed to attenuate caspase-3 activity induced by 6-OHDA. Furthermore, Western-blot analysis showed that Akt could be one of the specific signaling pathways stimulated by pEGCG in neuroprotection. It was demonstrated that 25 microM of 6-OHDA significantly suppressed the phosphorylation level of Akt. Only pEGCG at 10 microM markedly increased its phosphorylation level compared to 6-OHDA alone.

'Caffeinated tube food effect on pilot performance during a 9-hour simulated night time U-2 mission', Aviat Space Environ Med

'Statistically significant (p < 0.05) improvements in performance due to caffeine administration compared with placebo were present in all five cognitive tasks either as main effects, interactions, or absence of significant degradation in the caffeine treatment condition compared with the placebo condition. A majority of sleep deprivation-induced performance decrements were attenuated by 200 mg of caffeine in tube food consumed every 4 h, and in some cases, performance was improved beyond baseline levels.' -- Page 1038, col1 para 2

'Caffeine improves endurance in 75 year old citizens: a randomized, double-blind placebo-controlled cross-over study.', J Appl Physiol

'Caffeine increased cycling endurance by 25% [95% confidence interval (CI): 13-38; P = 0.0001] and isometric arm flexion endurance by 54% (95% CI: 29-83; P = 0.0001). Caffeine also reduced the rating of perceived exertion after 5 min of cycling by 11% (95% CI: 5-17; P = 0.002) and postural stability with eyes open by 25%(95% CI: 2-53; P = 0.03).' -- Page 631, col 2, para 3

'The physiological effects of caffeine in women during treadmill walking', J Strength Cond Res

'The 6 mg/kg dose of caffeine (but not the 3 mg/kg dose) increased VO2 (p=0.04), REE (p=0.03) and %VO2R (p=0.03) when compared to placebo. THe obeserved increase in REE (approx 0.23 kcal/minute) would not noticeably affect weight loss.' -- Page 165, col1, para 1, page 166 col2, para 2

'Caffeine: a double-blind, placebo-controlled study of its thermogenic, metabolic and cardiovascular effects in healthy volunteers.', Am J Clin Nutr

'Caffeine increased energy expenditure dose dependently and the thermogenic response was positively correlated with the response in plasma caffeine (r = 0.52; p less than 0.018), plasma lactate (r = 0.79; p less than 0.000001), and plasma triglyceride (r = 0.53; p less than 0.02).' -- Page 764, col 1, para 2

'The effect of caffeine, green tea and tyrosine on thermogenesis and energy', Eur J Clin Nutr

'Caffeine induced a thermogenic response of 6% above baseline value (72+/-25 kJ per 4 h, mean+/-s.e.) compared to placebo (P<0.0001). The thermogenic responses to GTE and tyrosine were not significantly different from placebo. Ad libitum EI was not significantly different between treatments but was reduced by 8% (-403+/-183 kJ),8% (-400+/-335 kJ) and 3% (-151+/-377 kJ) compared to placebo after intake of tyrosine, GTE and caffeine, espectively.' -- Page 4, col 2, para 1

'Green tea extract ingestion, fat oxidation, and glucose tolerance in healthy', The American journal of clinical nutrition

'Average fat oxidation rates were 17% higher after ingestion of GTE than after ingestion of placebo (0.41 +/- 0.03 and 0.35 +/- 0.03 g/min, respectively; P < 0.05). Moreover, the contribution of fat oxidation to total energy expenditure was also significantly higher, by a similar percentage, after GTE supplementation. The insulin area under the curve decreased in both the GTE and placebo trials (3612 +/- 301 and 4280 +/- 309 microIU/dL . 120 min, respectively; P < 0.01), and there was a concomitant increase of 13% in insulin sensitivity.' -- p780 Fig 1 and Table 1
