Tea compounds may boost attention span: Unilever - Nutra USA, 1/19/10 - "This study provided further evidence that the L-theanine/caffeine combination improves attention on the switch task ... The improvement in accuracy in combination with unaltered response speed is in line with previous studies ... Tentative evidence was [also] found that the effect of the L-theanine/caffeine combination on attention is not specific to the visual modality, as we found faster responses in both the visual and auditory modality on the intersensory task after the combination as compared to placebo ... Taken together with the previous studies, we conclude that a high dose of L-theanine combined with caffeine, at the level of a single cup of tea, can help to improve attention" - [Abstract] - See theanine at Amazon.com.

HPV is sexually transmitted and causes cervical cancer as well as other cancers, including those of the vulva, vagina, anus, and penis" - Note: They forgot head and neck cancer. See:
Multivitamins may cut lung cancer risk in smokers - Nutra USA, 1/13/10 - "It impressively shows, for example, that supplements containing beta-carotene, conceivably increasing the risk of lung cancer in heavy smokers when taken in extremely high doses over years, have the potential to reduce cancer risk even in smokers ... People who ate at least 12 servings of green leafy vegetables per month had a 17 per cent lower risk of methylation, while a daily folate intake of at least 750 micrograms was associated with a 16 per cent lower risk ... Current multivitamin users had a 43 per cent lower risk of gene methylation, added the researchers"
Green Tea May Cut Smokers' Lung Cancer Risk - WebMD, 1/12/10 - "Overall, the smokers and nonsmokers who didn't drink green tea had a more than five times greater risk of lung cancer compared to those who had at least a cup of green tea" - See green tea extract at Amazon.com.
Hypertension Drugs May Cut Alzheimer's Risk - WebMD, 1/12/10 - "The patients taking an angiotensin receptor blocker had a 19% lower risk of developing dementia compared to those taking lisinopril [an ACE inhibitor] and a 24% lower risk compared to use of other blood pressure/heart medications. People taking both an ACE inhibitor and an angiotensin receptor blocker, which both target the angiotensin system, had a 46% lower risk of dementia compared with those taking other medications" - Click here for reasons to consider temisartan (an ARB) as a first line treatment for hypertension.
BPA May Be Linked to Heart Disease Risk - WebMD, 1/12/10 - "Nearly everyone in the U.S. carries the plastics chemical BPA in their bodies ... high BPA levels were linked to a higher risk of heart disease, diabetes, and elevated liver enzymes"
Diabetes Accelerates Conversion of Mild Cognitive Impairment to Dementia - Medscape, 1/11/10 - "Our study demonstrates that individuals with mild cognitive impairment and diabetes are at increased risk of developing dementia"
L-theanine and caffeine improve task switching but not intersensory attention or subjective alertness - Appetite. 2010 Jan 13 - "The results support previous evidence that L-theanine and caffeine in combination can improve attention" - See theanine at Amazon.com.
Insulin-Like Growth Factor-I and Cancer Mortality in Older Men - J Clin Endocrinol Metab. 2010 Jan 15 - "Higher levels of IGF-I were associated with progressively higher risk of cancer death after adjusting for age, IGF-binding protein-1, adiposity, exercise, current smoking, and previous cancer. The adjusted risk of cancer death was statistically significant for IGF-I levels above 120 ng/ml, with magnitudes of effect ranging from 1.61 [95% confidence interval (CI) = 1.28-2.02] to 2.61 (95% CI = 1.46-4.64). For the 46% of men with IGF-I above 100 ng/ml, the risk of fatal cancer was 1.82 (95% CI = 1.11-2.96) compared to the risk with lower levels" - Note: IGF-1 is a measurement of growth hormone levels.
Telmisartan ameliorates hyperglycemia and metabolic profile in nonobese Cohen-Rosenthal diabetic hypertensive rats via peroxisome proliferator activator receptor-gamma activation - Metabolism. 2010 Jan 12 - "adiponectin was significantly (60%, P < .01) increased by telmisartan ... The telmisartan-induced increase in adiponectin was most probably associated with a decrease in glucose and tumor necrosis factor alpha levels. Therefore, in addition to its hypotensive effect, telmisartan demonstrated beneficial thiazolidinedione-like effects" - See telmisartan at OffshoreRx1.com.
Pro-ulcer effects of resveratrol in mice with indomethacin-induced gastric ulcers are reversed by l-arginine - Br J Pharmacol. 2010 Jan 8 - "Although resveratrol is currently being evaluated in pre-clinical studies as a potential cancer chemopreventive agent and cardiovascular stress-releasing compound, treatment with resveratrol severely delays healing of pre-existing gastric ulcers. Resveratrol treatment can also induce endothelial NOS (eNOS) expression ... Resveratrol significantly aggravated damage from indomethacin-induced gastric ulcers, and delayed healing, as shown by increased DS and MPO activity. The mRNA for cyclooxygenase (COX)-1, but not that for COX-2, was inhibited by resveratrol treatment, with reduced synthesis of PGE(2) by gastric tissue. However, resveratrol treatment induced eNOS gene expression and shifted the eNOS/iNOS balance. l-Arginine given before resveratrol in mice with indomethacin-induced ulcers significantly increased tissue NO synthesis and improved ulcer healing" - See L-arginine products at Amazon.com.
Examination of the Antiglycemic Properties of Vinegar in Healthy Adults - Ann Nutr Metab. 2010 Jan 4;56(1):74-79 - "Vinegar reduces postprandial glycemia (PPG) in healthy adults ... Two teaspoons of vinegar ( approximately 10 g) effectively reduced PPG, and this effect was most pronounced when vinegar was ingested during mealtime as compared to 5 h before the meal ... The antiglycemic properties of vinegar are evident when small amounts of vinegar are ingested with meals composed of complex carbohydrates. In these situations, vinegar attenuated PPG by approximately 20% compared to placebo" - See apple cider vinegar at Amazon.com - 1 Source Natural 500 mg tablet equals 2 tsb of vinegar. 4.5 tablets equals about 3 tablespoons by my calculations.
Pioglitazone improves endothelium-dependent vasodilation in hypertensive patients with impaired glucose tolerance in part through a decrease in oxidative stress - Atherosclerosis. 2010 Jan 4 - "Pioglitazone improved endothelial function in hypertensive patients with IGT through an increase in nitric oxide bioavailability by, in part, a decrease in oxidative stress" - See pioglitazone at OffshoreRx1.com. Pioglitazone is one that I take to help prevent diabetes and for anti-aging. See my Insulin and Aging page.
