large quantities ... Because of lax or nonexistent regulation, 4.5 billion
people in developing countries are chronically exposed to vast amounts of
this toxin, called aflatoxin -- often hundreds of times higher than safe
levels"

"the 6 percent walnut study diet is equivalent to a human eating 1 ounce, or

containing 2 percent or 6 percent walnuts were able to improve age-related
motor and cognitive shortfalls, while the 9 percent walnut diet impaired
reference memory. Walnuts, eaten in moderation, appear to be among other
foods containing polyphenols and bioactive substances that exhibit multiple

Antioxidant-rich Pecans Can Protect Against Unhealthy Oxidation -
Science Daily, 10/3/06 - "adding

Researchers suggest that this positive effect was in part due to the pecan's
significant content of vitamin E ... Pecans are especially rich in one form
of vitamin E -- gamma tocopherol"

Effects
of pistachios on body weight in Chinese subjects with metabolic syndrome
- Nutr J. 2012 Apr 3;11(1):20 - "randomized to
consume either the recommended daily serving of 42 g pistachios (RSG), a
higher daily serving of 70 g pistachio (HSG) or no pistachios (DCG) for 12
weeks ... glucose values 2 h after a 75 gm glucose challenge were
significantly lower at week 12 compared with baseline values in the HSG
group (1.13 +/- 2.58 mmol/L, p = 0.02), and a similar trend was noted in the
RSG group (0.77 +/-2.07 mmol/L, p = 0.06), while no significant change was
seen in the DCG group (0.15 +/- 2.27 mmol/L, p = 0.530). At the end of
study, serum triglyceride levels were significantly lower compared with
baseline in the RSG group (0.38 +/- 0.79 mmol/L, p = 0.018), but no
significant changes were observed in the HSG or DCG groups ... Despite
concerns that pistachio nut consumption may promote weight gain, the daily
ingestion of either 42 g or 70 g of pistachios for 12 weeks did not lead to
weight gain or an increase in waist-to-hip ratio in Chinese subjects with
metabolic syndrome. In addition, pistachio consumption may improve the risk
factor associated with the metabolic syndrome"

Alternative Healthy Eating Index and mortality over 18 y of follow-up:
results from the Whitehall II cohort - Am J Clin Nutr. 2011 May 25 -
"Indexes of diet quality have been shown to be
associated with decreased risk of mortality in several countries. It remains
unclear if the Alternative Healthy Eating Index (AHEI), designed to provide
dietary guidelines to combat major chronic diseases, is related to mortality
risk. OBJECTIVE: We aimed to examine the association between adherence to
the AHEI and cause-specific mortality over 18 y of follow-up in a British
working population. Design: Analyses are based on 7319 participants (mean
age: 49.5 y; range: 39-63 y; 30.3% women) from the Whitehall II Study. Cox
proportional hazards regression models were performed to analyze
associations of the AHEI (scored on the basis of intake of 9 components:
vegetables, fruit, nuts and soy, white or red meat, trans fat,
polyunsaturated or saturated fat, fiber, multivitamin use, and alcohol) with
mortality risk. Results: After potential confounders were controlled for,
participants in the top compared with the bottom third of the AHEI score
showed 25% lower all-cause mortality [hazard ratio (HR): 0.76; 95% CI: 0.61,
0.95] and >40% lower mortality from cardiovascular disease (CVD; HR: 0.58;
95% CI: 0.37, 0.91). Consumption of nuts and soy and moderate alcohol intake
appeared to be the most important independent contributors to decreased
mortality risk. The AHEI was not associated with cancer mortality or
noncancer/non-CVD mortality. Conclusion: Our findings suggest that the
encouragement of adherence to the AHEI dietary recommendations constitutes a
valid and clear public health recommendation that would decrease the risk of
premature death from CVD"

Arecoline N-Oxide: Its Mutagenicity and Possible Role as Ultimate Carcinogen
in Areca Oral Carcinogenesis - J Agric Food Chem. 2011 Mar 3 -
"The areca nut is the most widely consumed
psychoactive substance in Taiwan, India, and Southeast Asia. It is
considered to be an environmental risk factor for the development of oral
submucous fibrosis and cancer. Arecoline, the major alkaloid of areca nut,
has been known to cause cytotoxicity and genotoxicity in various systems.
However, the active compound accounting for arecoline-induced damage in
normal human oral cells is still uncharacterized. The present study was
undertaken to identify the active metabolite of arecoline that might induce
damage in human oral tissues and cause mutagenicity in Salmonella
typhimurium tester strains TA 100 and TA 98. It is interesting to find that
the major metabolite of arecoline, arecoline N-oxide, is moderately
mutagenic to these Salmonella tester strains. This mutagenicity was potently
inhibited by sulfhydryl compounds, namely, glutathione, N-acetylcysteine,
and cysteine, whereas methionine is inactive in this inhibition. The
mutagenicity of arecoline N-oxide was strongly inhibited by the N-oxide
reducing agent titanium trichloride. The possible role of arecoline N-oxide
in the induction of oral carcinogenesis by areca nut chewing is discussed"
