in this population consisted of: vegetables (19.3 percent), dairy (17.3
percent), grain products (14.7 percent), soyfoods (11.8 percent), fruit (7.3
percent) and fish (6.2 percent). However, the researchers stress that there was
no positive association with prostate cancer risk and any one particular food
source ... Among men with less than average BMI (median BMI was 22.9 kg/m2), the
researchers found a twofold increased risk of prostate cancer"
Surgery
outperforms drug therapy in treatment of benign prostatic hyperplasia, research
finds - Science Daily, 5/29/10 - "Patients who
underwent transurethral resection of the prostate (TURP) had the greatest
decrease in both symptoms and incontinence compared to other treatment groups.

High
blood cortisol levels significantly increases death rate in patients with acute
coronary syndrome - Science Daily, 5/27/10 - "1036
patients with acute coronary syndrome
were studied for an average period of 7.7 years. There were no significant
differences in the serum cortisol levels
between patients with and without acute coronary syndrome. However, the patients
with ACS and high cortisol levels had a significantly elevated number of deaths
when compared to the patients with ACS and the lowest cortisol levels. 758 total
deaths were reported during the follow-up period. The ACS patients with the
highest cortisol levels (i.e. the highest 25% serum cortisol) were significantly
more likely to die from fatal cardiovascular events than those with the lowest
cortisol levels (the lowest 25% serum cortisol). (The hazard ratio for highest
versus lowest quartile of SCC was 1.89"
Brief
exercise reduces impact of stress on cell aging, study shows - Science
Daily, 5/27/10 - "A growing body of research suggests
that short telomeres are linked to a range of
health problems, including coronary heart disease and diabetes, as well as early
death ... In the study, 62 post-menopausal women -- many of whom were caring for
spouses or parents with dementia ... when participants were divided into groups
-- an inactive group, and an active group (i.e., they met federal
recommendations for 75 minutes of weekly physical
activity) -- only the inactive high stress group had shorter telomeres. The
active high stress group did not have shorter telomeres. In other words, stress
predicted shorter telomeres in the sedentary group, but not in the active group"

Consumption
of filtered and boiled coffee and the risk of incident cancer: a prospective
cohort study - Cancer Causes Control. 2010 May 30 -
"No associations were found for all cancer sites combined, or for prostate or
colorectal cancer. For breast cancer, boiled coffee
>/=4 versus <1 occasions/day was associated with a reduced risk (HR = 0.52, CI =
0.30-0.88, p (trend) = 0.247). An increased risk of premenopausal and a reduced
risk of postmenopausal breast cancer were found for both total
(HR(premenopausal) = 1.69, CI = 0.96-2.98, p (trend) = 0.015, HR(postmenopausal)
= 0.60, CI = 0.39-0.93, p (trend) = 0.006) and filtered coffee

Advanced
Glycation End Products in Foods and a Practical Guide to Their Reduction in the
Diet - J Am Diet Assoc. 2010 Jun;110(6):911-916.e12 -
"Modern diets are largely heat-processed and as a result
contain high levels of
advanced glycation end products (AGEs). Dietary advanced glycation end
products (dAGEs) are known to contribute to increased oxidant stress and
inflammation, which are linked to the recent epidemics of diabetes and
cardiovascular disease ... Based on the findings, dry heat promotes new dAGE
formation by >10- to 100-fold above the uncooked state across food categories.
Animal-derived foods that are high in fat and protein are generally AGE-rich and
prone to new AGE formation during cooking. In contrast, carbohydrate-rich foods
such as vegetables, fruits, whole grains, and milk contain relatively few AGEs,
even after cooking. The formation of new dAGEs during cooking was prevented by
the AGE inhibitory compound aminoguanidine and significantly reduced by cooking
with moist heat, using shorter cooking times, cooking at lower temperatures, and
by use of acidic ingredients such as lemon juice or vinegar"
Non-steroidal anti-inflammatory drug (NSAID) use and breast cancer risk in the
Western New York Exposures and Breast Cancer (WEB) Study - Cancer Causes
Control. 2010 May 25 - "Recent
aspirin use was inversely associated with

0.68-0.94); the strongest reduction in risk was observed among those who took
>/=2 pills/day on days that aspirin was taken (OR 0.74, 95% CI: 0.61-0. 90).
Adult lifetime use was also associated with breast cancer risk (>10 days/month,
adjusted OR 0.68, 95% CI: 0.46-1.00). Use of ibuprofen or acetaminophen was not
associated with breast cancer"

Calcium And Vitamin D May Not Be The Only Protection Against Bone Loss -
Science Daily, 12/3/08 - "Diets that are high in
protein and cereal grains produce an excess of acid in the body which may
increase calcium excretion and weaken bones ... When fruits and vegetables
are metabolized they add bicarbonate, an alkaline compound, to the body ...
bicarbonate had a favorable effect on bone resorption and calcium excretion
... 171 men and women aged 50 and older were randomized to receive placebo
or doses of either: potassium bicarbonate, sodium bicarbonate, or potassium
chloride for three months. Researchers found that subjects taking
bicarbonate had significant reductions in calcium excretion, signaling a
decrease in bone resorption"

Rice bran contains high arsenic levels, study - Nutra USA, 8/26/08 -
"rice bran and rice bran solubles contain inorganic
arsenic levels of around 1mg/kg dry weight, which is around 10-20 times the
concentration found in bulk grain ... The tests were conducted on four bran
solubles, one defatted bran, one riceo-ex and three bran products ... Out of
the bran solubles, testing found the highest inorganic arsenic level of
0.86mg/kg in a sample from Holistic Enterprises, Santa Ana, USA. A sample
from NutraCea, USA was found to contain 0.82mg/kg. A sample from Pure Planet
Products, Long Beach, CA, USA, contained 0.71mg/kg and one from Integris,
RiSO Triene, USA, contained 0.61mg/kg ... The rice bran products tested were
from: General Dietary, UK & Eire; The Barry Farm, Ohio, USA; and Tsuno Rice
Fine Chemicals Co, Japan. They contained levels of 0.48, 0.64 and 1.65mg/kg
respectively ... The defatted bran and the riceo-ex products were again
sourced from Japan’s Tsuno Rice, and contained 1.16 and 1.88mg/kg
respectively" - That doesn't help me out much. I've been getting the

Whole-Grain
Intake and Cereal Fiber Are Associated with Lower Abdominal Adiposity in Older
Adults - J Nutr. 2009 Sep 2 - "After adjustment for
covariates, whole-grain intake was inversely associated with BMI [26.8 kg/m(2)
(25.7-28.1) vs. 25.8 kg/m(2) (24.6-27.1), (95% CI); P-trend = 0.08], percent
body fat [34.5% (32.7-36.3) vs. 32.1% (30.1-34.1); P-trend = 0.02], and percent
trunk fat mass [43.0% (40.4-45.5) vs. 39.4% (36.7-42.1); P-trend = 0.02] in the
lowest compared with the highest quartile category of whole-grain intake.
Refined grain intake was not associated with any measure of body fat
distribution. Cereal fiber was inversely associated with BMI [27.3 kg/m(2)
(26.1-28.6) vs. 25.4 kg/m(2) (24.3-26.7); P-trend = 0.012], percent body fat
[34.7% (32.8-36.6) vs. 31.5% (29.4-33.5); P-trend = 0.004], and percent trunk
fat mass [42.8% (40.2-45.4) vs. 37.8% (35.0-40.6) ... Higher intakes of cereal
fiber, particularly from whole-grain sources, are associated with lower total
percent body fat and percent trunk fat mass in older adults"

Intake of
plant foods and associated nutrients in prostate cancer risk - Nutr Cancer.
2009;61(2):216-24 - "Plant foods and associated
nutrients may impact prostate cancer (PC) risk and survival ... Reduced PC risk
was associated with the highest tertile of cryptoxanthin (OR = 0.51; 95% CI =
0.35-0.75), fiber (OR = 0.56; 95% CI = 0.35-0.89), vitamin C (OR = 0.60; 95% CI
= 0.41-0.88), and fruits and/or fruit juices (OR = 0.46; 95% CI = 0.31-0.68),
with significant linear trends. Increased risk of PC was associated with the
highest tertile of protein (OR = 1.99; 95% CI = 1.05-3.79) and daily servings of
grains (OR = 1.99; 95% CI = 1.23-3.22) with significant linear trends"

Whole-grain consumption is associated with a reduced risk of noncardiovascular,
noncancer death attributed to inflammatory diseases in the Iowa Women's Health
Study - Am J Clin Nutr. 2007 Jun;85(6):1606-14 -
"The reduction in inflammatory mortality associated with habitual whole-grain
intake was larger than that previously reported for coronary heart disease and
diabetes. Because a variety of phytochemicals are found in whole grains that may
directly or indirectly inhibit oxidative stress, and because oxidative stress is
an inevitable consequence of inflammation, we suggest that oxidative stress
reduction by constituents of whole grain is a likely mechanism for the
protective effect"

Blood glucose lowering effects of brown rice in normal and diabetic subjects
- Int J Food Sci Nutr. 2006 May-Jun;57(3-4):151-8 - "The
total sugar released in vitro was 23.7% lower in brown rice than in milled rice.
In healthy volunteers, the glycemic area and glycemic index were, respectively,
19.8% and 12.1% lower (p < 0.05) in brown rice than milled rice, while in
diabetics, the respective values were 35.2% and 35.6% lower. The effect was
partly due to the higher amounts of phytic acid, polyphenols, dietary fiber and
oil in brown compared to milled rice and the difference in some physicochemical
properties of the rice samples such as minimum cooking time and degree of
gelatinisation"

Muesli with 4 g oat beta-glucans lowers glucose and insulin responses after a
bread meal in healthy subjects - Eur J Clin Nutr. 2007 Apr 4 -
"Muesli enriched with 4 g of beta-glucans reduces
postprandial glucose and insulin levels to a breakfast based on high glycaemic
index products. A total of 4 g of beta-glucans from oats seems to be a critical
level for a significant decrease in glucose and insulin responses in healthy
people"

Changes in whole-grain, bran, and cereal fiber consumption in relation to
8-y weight gain among men - Am J Clin Nutr. 2004 Nov;80(5):1237-45 -
"an increase in whole-grain intake was inversely
associated with long-term weight gain (P for trend < 0.0001). A
dose-response relation was observed, and for every 40-g/d increment in
whole-grain intake from all foods, weight gain was reduced by 0.49 kg. Bran
that was added to the diet or obtained from fortified-grain foods further
reduced the risk of weight gain (P for trend = 0.01), and, for every 20 g/d
increase in intake, weight gain was reduced by 0.36 kg"

Why whole grains are protective: biological mechanisms - Proc Nutr Soc
2003 Feb;62(1):129-34 -
"First, whole grains are concentrated sources of
dietary fibre, resistant starch and oligosaccharides, carbohydrates that
escape digestion in the small intestine and are fermented in the gut,
producing short-chain fatty acids (SCFA). SCFA lower colonic pH, serve as an
energy source for the colonocytes and may alter blood lipids. These
improvements in the gut environment may provide immune protection beyond the
gut. Second, whole grains are rich in antioxidants, including trace minerals
and phenolic compounds, and these compounds have been linked to disease
prevention. Additionally, whole grains mediate insulin and glucose
responses. Although lower glycaemic load and glycaemic index have been
linked to diabetes and obesity, risk of cancers such as colon and breast
cancer have also been linked to high intake of readily-available
carbohydrate. Finally, whole grains contain many other compounds that may
protect against chronic disease. These compunds include phytate,
phyto-oestrogens such as lignan, plant stanols and sterols, and vitamins and
minerals."

Whole grains protect against atherosclerotic cardiovascular disease -
Proc Nutr Soc 2003 Feb;62(1):135-42 -
"Generous intake of whole grains also provides
protection from development of diabetes and obesity. Diets rich in
wholegrain foods tend to decrease serum LDL-cholesterol and triacylglycerol
levels as well as blood pressure while increasing serum HDL-cholesterol
levels. Whole-grain intake may also favourably alter antioxidant status,
serum homocysteine levels, vascular reactivity and the inflammatory state.
Whole-grain components that appear to make major contributions to these
protective effects are: dietary fibre; vitamins; minerals; antioxidants;
phytosterols; other phytochemicals. Three servings of whole grains daily are
recommended to provide these health benefits"

Whole-grain and fiber intake and the incidence of type 2 diabetes -
AJCN, 3/1/03 -
"Whole-grain consumption was associated with a
reduced risk of type 2 diabetes. The
relative risk (adjusted for age, sex, geographic area, smoking status, body
mass index, energy intake, and intakes of vegetables, fruit, and berries)
between the highest and lowest quartiles of whole-grain consumption was 0.65
(95% CI: 0.36, 1.18; P for trend = 0.02). Cereal fiber intake was also
associated with a reduced risk of type 2 diabetes. The relative risk between
the extreme quartiles of cereal fiber intake was 0.39"
