Multivitamins, but Not
Cocoa, Tied to Slowed Brain Aging - Medscape, 11/11/21 -
"Taking a daily multivitamin for 3 years is associated
with a 60% slowing of cognitive aging, with the effects especially pronounced in
patients with cardiovascular (CVD) disease ... In addition to testing the effect
of a daily multivitamin on cognition the COSMOS-Mind study also examined the
effect of cocoa flavonols, but showed no beneficial effect" - See

Association between
vitamin B group supplementation with changes in % flow-mediated dilatation and
plasma homocysteine levels: a randomized controlled trial - J Clin Biochem
Nutr. 2019 May;64(3):243-249 - "A significant increase in serum B vitamins and
vitamin C levels, and a reduction in plasma homocysteine levels were observed.
The mean serum homocysteine level pre- and post-intervention was 9.8 and 8.2
µmol/L in the early intervention group and 10.8 and 7.4 µmol/L in the later
intervention group (p<0.01). However, no significant changes in flow-mediated
dilatation was found. Low-dose multivitamin supplementation including B vitamins
is associated with a significant reduction in plasma homocysteine levels among
patients with one or more components of metabolic syndrome" - [Nutra

Antioxidants may prevent cognitive impairment in diabetes - Science Daily,
11/20/18 - "Long-term decline in cognitive function,
with everyday learning and memory tasks becoming harder and taking longer to
complete, is a common consequence for patients who frequently experience low
blood sugar levels when using insulin to manage their diabetes. Previous studies
in mice have shown that reoccurring episodes of low blood sugar leads an
accumulation of cell damaging free radicals in the brain. Whether this build-up
of free radical stress directly effects cognitive function, and if the body's
own antioxidative systems, which can remove free radicals, can be harnessed to
counteract these changes and improve quality of life is not known."

Antioxidants and amino acids could play role in the treatment of psychosis -
Science Daily, 3/22/18 - "certain nutrient supplements,
used alongside standard treatment, may improve mental health in young people
with psychosis more than standard treatment alone ... 4 grams of Taurine per day
reduced psychotic symptoms within just 12 weeks ... Certain antioxidant
supplements, such as n-acetyl cysteine and vitamin C, may also be effective --
particularly for patients with high levels of 'oxidative stress' ... Studies on
omega-3 supplements showed that although these appear to improve brain health in
young people with psychosis, the evidence for actually reducing psychotic
symptoms is conflicting" - See

Vitamin
deficiency in later life - Science Daily, 12/15/17 - ""Fifty-two percent of
the examined older adults had vitamin D levels below 50 nmol/L and thus had a
suboptimal vitamin D status." The scientists also observed shortages with regard
to some of the other micronutrients. Notably, twenty-seven percent of older
adults had vitamin B12 levels below the cut-off. Moreover, in eleven percent of
older adults, iron levels were too low, and almost nine percent did not have
enough folate in their blood."

Antioxidants and Dementia
Risk: Consideration through a Cerebrovascular Perspective - Nutrients. 2016
Dec 20;8(12) - "An emerging body of evidence suggests
that the integrity of the cerebrovascular blood-brain barrier (BBB) is centrally
involved in the onset and progression of cognitive impairment and dementia ...
Conclusively, there is a compelling body of evidence that suggest antioxidants
may prevent cognitive decline and dementia by protecting the integrity and
function of BBB and, indeed, further studies are needed to directly examine
these effects in addition to underlying molecular mechanisms" - See

important for individuals to consume foods high in antioxidants and to continue
exercising, especially after the age of 65. This could help increase the levels
of the related metabolites in the body and improve body conditions"

Fresh
faced: Looking younger for longer - Science Daily, 1/10/14 -
"While UVB radiation easily causes sunburn, UVA
radiation penetrates deeper, damaging our DNA by generating free radicals which
degrades the collagen that gives skin its elastic quality ... the most potent
anti-oxidants were those that targeted the batteries of the skin cells, known as
the mitochondria. They compared these mitochondrial-targeted anti-oxidants to
other non-specific antioxidants such as resveratrol, found in red wine, and
curcumin found in curries, that target the entire cell. They found that the most
potent mitochondrial targeted anti-oxidant was Tiron which provided 100%,
protection of the skin cell against UVA sun damage and the release of damaging
enzymes causing stress-induced damage ... Tiron is not a naturally occurring
compound and has not yet been tested for toxicity in humans although there have
been a few studies on rats ... Antioxidants in our diets from green tea,
resveratrol which is found in red wine, turmeric which is used in curries and
lycopene found in tomatoes, as well as some components in cosmetic creams, are
known to neutralise this damage within the cells. They can slow down the damage
and the rate of aging and potentially lower the rate of other sun-induced skin
lesions ... Resveratrol, the antioxidant found in red wine, was found to protect
against 22% of both the ultraviolet A radiation and stress-induced damage. NAC,
a frequently used laboratory-based anti-oxidant, offered 20% protection against
oxidative stress and 8% against UVA and curcumin offered 16% protection against
oxidative stress and 8% against UVA" - See

Misleading News on Multivitamins: How Media Missed the Value of Supplements
- U.S. News, 12/30/13 - "These news headlines (headlines
like "Are Multivitamins a Waste of Money?," "Vitamins Should Be Avoided" and
"Your Multivitamins aren't Doing a D**n Thing" ) and even the editorial in one
of medicines leading journals – the Annals of Internal Medicine – do mislead
unless you are a fine-print reader. And the news headlines did not mention the
fine print ... What the fine print said were that all those people in these
studies had normal nutrition and had no vitamin deficiencies, were not
potentially or actually pregnant and weren't tested for quality-of-life issues
like eyesight. And the news media ignored the significant 8 percent reduction in
non-prostate cancers for men over 50, significant 18 percent reduction in
non-prostate cancers for men over 70 and the non-significant (because they
didn't study enough people) 11 percent reduction in cardiovascular events and
deaths (of a high-dose vitamin regimen compared with a low-dose one – yes,
everyone in that study received vitamin supplementation)."

Multivitamins With Minerals May Protect Older Women With Invasive Breast Cancer
- Science Daily, 10/9/13 - "The research was conducted
as part of the Women's Health Initiative Clinical Trials and the Women's Health
Initiative(WHI)Observational Study. Combined, the two studies include data from
161,608 postmenopausal women ages 50 to 79 when they first joined the study ...
A comparison of mortality rates revealed that women with invasive breast cancer
who took multivitamin/mineral supplements were 30 percent less likely to die
from their cancers than women with invasive breast cancer who hadn't taken the
supplements. Could differences between the multivitamin/mineral users and
nonusers account for this finding? The researchers looked at many possible
confounding factors including additional supplements that the women took, their
smoking status, education, race/ethnicity, weight, depression, alcohol use,
physical activity, age at breast cancer diagnosis, and diabetes. The association
between regular use of multivitamin/mineral supplements and reduced risk of
death persisted even after these factors were taken into account" - See

Optimism Linked to
Higher Antioxidant Levels - Medscape, 1/15/13 - "for
every standard deviation increase in optimism, there was an increase in
carotenoid concentrations of 3% to 13% in age-adjusted models ... Antioxidants
are good examples of positive functioning because they help to inhibit other
molecules from producing free radicals that damage cells and contribute to
disease ... Although optimism was associated with an increase in carotenoids,
they also found a link to increased levels of vitamin E ... we can't
conclusively determine whether optimism leads to healthier levels of
antioxidants or vice versa" - See

Antioxidants may ease peripheral arterial disease (PAD) blood pressure increase,
study suggests - Science Daily, 11/8/12 - "Low
antioxidant levels contribute to increased blood pressure during exercise for
people with peripheral arterial disease ... Antioxidants prevent the reactive
oxygen species from damaging cells ... "This indicates that during normal,
everyday activities such as walking, an impaired antioxidant system -- as well
as other factors -- plays a role in the increased blood pressure response to
exercise," Muller said. "Therefore, supplementing the diet with antioxidants may
help these patients, but more studies are needed to confirm this concept.""

antioxidants, mainly from fruits and vegetables, can significantly reduce the
risk of myocardial infarction ... Total antioxidant capacity measures in a
single value all antioxidants present in diet and the synergistic effects
between them ... followed 32,561 Swedish women aged 49-83 from September 1997
through December 2007 ... The women were categorized into five groups of total
antioxidant capacity of diet ... Women in the group with the highest total

Iron, vitamins could affect physical fitness in adolescents - Science Daily,
8/9/12 - "Because nutrition and fitness are intertwined
-- for example, iron forms part of hemoglobin, which carries oxygen to muscles,
and antioxidants such as vitamin C aid in rebuilding damage after intense
training -- these two findings could be related. In a new study, researchers
have found that adolescents' blood levels of various micronutrients are
correlated with how well they performed in certain physical fitness tests.
Though these results don't prove causality, they suggest a new relationship
between different measures of adolescent health ... The researchers found that
blood levels of certain micronutrients were intimately connected with the
volunteers' performance on the physical fitness tests. For cardiorespiratory
fitness, concentrations of hemoglobin, retinol, and vitamin C in males and
beta-carotene and vitamin D in females was associated with VO2max. For muscular
fitness, concentrations of hemoglobin, beta-carotene, retinol, and
alpha-tocopherol in males and beta-carotene and vitamin D in females was
associated with performing better on the standing long jump test"

Do Fruits and Veggies Make You More Attractive? - WebMD, 3/7/12 -
"changes in the redness and yellowness of skin in white
people may be linked to the number of servings of fruit and vegetables they eat
on a daily basis. These antioxidant-rich foods, which are loaded with
plant-based pigments, seem to affect skin tone ... They suggest it's the
carotenoids -- the red, yellow, and orange pigments in fruits and vegetables --
that play an important role in skin tone. Foods such as carrots, sweet potatoes,
squash, and apricots are rich in beta-carotene, as are some dark green
vegetables, including spinach and kale ... Another carotenoid is lycopene, which
is found in tomatoes and pink grapefruits" - See

Antioxidant spices, like turmeric and cinnamon, reduce negative effects of
high-fat meal - Science Daily, 8/10/11 - "Normally,
when you eat a high-fat meal, you end up with high levels of triglycerides, a
type of fat, in your blood ... If this happens too frequently, or if
triglyceride levels are raised too much, your risk of heart disease is
increased. We found that adding spices to a high-fat meal reduced triglyceride
response by about 30 percent, compared to a similar meal with no spices added
... Antioxidants, like spices, may be important in reducing oxidative stress and
thus reducing the risk of chronic disease"

Reduction of
circulating superoxide dismutase activity in type 2 diabetic patients with
microalbuminuria and its modulation by telmisartan therapy - Hypertens Res.
2011 Aug 4 - "Interestingly, the telmisartan treatment
not only reduced the circulating levels of two oxidative stress markers,
8-hydroxy-2'-deoxyguanosine (8-OHdG) and nitrotyrosine (NT), but also enhanced
serum SOD activity. Notably, a significant correlation was observed between the
increase in serum SOD activity and the reduction in albuminuria. We further
compared the anti-oxidative effect of telmisartan with that of losartan, another
member of the ARB class, by implementing an 8-week interval crossover treatment
with these ARBs in another 12 microalbuminuric type 2 diabetic patients. The
patients showed higher serum SOD activity, and lower circulating levels of
8-OHdG and NT, during treatment with telmisartan than with losartan. These
results suggest that telmisartan has a more potent antioxidative effect through
its ability to enhance SOD activity in type 2 diabetic patients with
microalbuminuria" - See telmisartan at

Antioxidants of growing interest to address infertility, erectile dysfunction
- Science Daily, 7/28/11 - "A growing body of evidence
suggests that antioxidants may have significant value in addressing infertility
issues in both women and men, including erectile dysfunction, and researchers
say that large, specific clinical studies are merited to determine how much they
could help ... Some commonly used antioxidants, such as vitamins C and E, could
help, Hagen said. But others, such as lipoic acid, are a little more
cutting-edge and set up a biological chain reaction that has a more sustained
impact on vasomotor function and health ... Polyphenols, the phytochemicals that
often give vegetables their intense color and are also found in chocolate and
tea, are also of considerable interest"

A novel
and potent antioxidant found in tomato plants, initial results suggest -
Science Daily, 7/22/11 - "A team of researchers from the
Institute of Molecular and Cell Biology (IBMCP) -a joint centre of the
Universitat Politècnica de València and CSIC, the Spanish National Research
Council- have identified a novel and potent natural antioxidant occurring in
tomato plants. It is a phenolic substance that is synthesised by the tomato
plant when it is subjected to biotic stress. Until now, it was completely
unknown ... The UPV and CSIC have registered the national and international
patents of the new antioxidant and the laboratory procedures used to isolate and
synthesise it chemically ... the antioxidant power of the new compound is much
higher -14 times higher, to be precise- than, for example, that of resveratrol,
a well-known antioxidant, found in red wine, which can delay cellular aging. In
addition, it is 4.5 times more potent than vitamin E and 10 times more potent
than vitamin C" - Note: The patent thing makes you wonder if the claims
are overblown though.

High
Antioxidant Intake May Lower Risk for Early AMD - Medscape, 6/14/11 -
"We assessed the intake of antioxidants, zinc, and ω-3
fatty acids in daily foods, diagnosed the onset of early AMD during a lengthy
follow-up, and investigated the risk-reducing effect of these nutrients in the
various genotypes of CFH [complement factor H] Y402H and LOC387715 A69S ...
Median follow-up duration was 8.6 years ... There appeared to be a possible
biological interaction between the CFH Y402H genotype and intakes of zinc,
β-carotene, lutein/zeaxanthin, and eicosapentaenoic/docosahexaenoic acid
(EPA/DHA), and between the LOC387715 A69S genotype and zinc and EPA/DHA, based
on significant synergy indices ... High dietary intake of nutrients with
antioxidant properties reduces the risk of early AMD in those at high genetic
risk"

How
vitamins and minerals may prevent age-related diseases - Science Daily,
5/31/11 - "Severe deficiency of the vitamins and
minerals required for life is relatively uncommon in developed nations, but
modest deficiency is very common and often not taken seriously. A new research
published online in the FASEB Journal, however, may change this thinking as it
examines moderate selenium and vitamin K deficiency to show how damage
accumulates over time as a result of vitamin and mineral loss, leading to
age-related diseases ... If the principles of the theory, as demonstrated for
vitamin K and selenium, can be generalized to other vitamins and minerals, this
may provide the foundation needed ... They discovered a highly sophisticated
array of mechanisms at cellular and tissue levels that, when selenium is
limited, protect essential selenium-dependent proteins at the expense of those
that are nonessential. They also found that mutations in selenium-dependent
proteins that are lost on modest selenium deficiency result in characteristics
shared by age-related diseases including cancer, heart disease, and loss of
immune or brain function"

Dietary
Antioxidant and Mineral Intake in Humans Is Associated with Reduced Risk of
Esophageal Adenocarcinoma but Not Reflux Esophagitis or Barrett' Esophagus -
J Nutr. 2010 Aug 11 - "We found that overall antioxidant
index, a measure of the combined intake of vitamin C, vitamin E, total
carotenoids, and selenium, was associated with a reduced risk of EAC [odds ratio
(OR) = 0.57; 95% CI = 0.33-0.98], but not BE (OR = 0.95; 95% CI = 0.53-1.71) or
RE (OR = 1.60; 95% CI = 0.86-2.98), for those in the highest compared with
lowest category of intake. Those in the highest category of vitamin C intake had
a lower risk of EAC (OR = 0.37; 95% CI = 0.21-0.66; P-trend = 0.001) and RE (OR
= 0.46; 95% CI = 0.24-0.90; P-trend = 0.03) compared with those in the lowest
category. Vitamin C intake was not associated with BE, and intake of vitamin E,
total carotenoids, zinc, copper, or selenium was not associated with EAC, BE, or
RE. In conclusion, the overall antioxidant index was associated with a reduced
risk of EAC. Higher dietary intake of vitamin C was associated with a reduced
risk of EAC and RE. These results suggest that antioxidants may play a role in
the pathogenesis of RE and EAC and may be more important in terms of progression
rather than initiation of the disease process"

Natural
substance NT-020 aids aging brains in rats, study finds - Science Daily,

and we have previously shown that natural compounds made from blueberries, green
tea, and amino acids, such as carnosine, are high in antioxidants and have
anti-inflammatory and anti-oxidative activity .... The combination of these
nutrients, called NT-020, creates a synergistic effect that promotes the
proliferation of stem cells in the aged animals ... NT-020 may have not only a
positive effect on the stem cell niche ... NT-020 may have far-reaching effects
on organ function beyond the replacement of injured cells, as demonstrated by
cognitive improvement in the NT-020 group"

Well-defined quantity of antioxidants in diet can improve insulin resistance,
study finds - Science Daily, 6/21/10 - "For groups C
and D, the researchers prescribed a diet enriched in antioxidant, with a
calculated intake, 800 to 1,000 milligrams a day, coming from fruits and
vegetables, but group D also took metformin ... Despite similar weight loss in
all the groups, only the two groups receiving the antioxidant diet (groups C and
D) had a significant decrease in insulin resistance ... Group D had the best
improvement in insulin resistance on some measures of insulin response to an
oral glucose tolerance test ... We think that a total antioxidant level of 800
to 1,000 milligrams a day is safe and probably not close to the maximum
tolerable level"

of stem cells circulating in the blood ... Hematopoietic stem cells and
endothelial progenitor cells increased after taking the nutritional supplement,
suggesting that the supplement may be a useful stimulator for both types of stem
cells. In this study, the levels of these stem cells peaked at 2-7 days and
started to drop at 14 days, suggesting that this supplement could be used for
continuous treatment for conditions associated with decreases in these stem
cells such as Alzheimer's Disease ... it may be possible that our supplement

researchers to suggest at a meeting in Atlanta this past weekend that a diet
high in antioxidants could play an important role in preserving muscle function
in older adults ... Muscle strength is really a marker of aging ... Muscle
strength starts declining when people are in their 40s, but it decreases
dramatically after age 60 ... At this point, it's not clear whether vitamins C
and E specifically help preserve muscle strength, or if intake of these

Antioxidants needed by exercising populations: Nutritionist - Nutra USA,
5/14/09 - "Commenting on the design of the study, Dr
Childs said it was unclear if the subjects encountered the same absolute level

hence stimulus for antioxidant up-regulation. “Because of this, the reported
‘prevention of the ‘health promoting effects of antioxidants’ may be nothing
more than an experimental artefact,” ... In addition, Dr Childs said that
comments by the authors that antioxidants may block many of the beneficial
effects of exercise were a “gross over extrapolation of the experimental
findings on two levels”"

PGCl-beta, and PPAR-gamma expression in skeletal muscle following 4 weeks of
exercise training in previously untrained, antioxidant naïve individuals” and
“markedly reduced exercise-related induction” in those taking antioxidants,
based on these limited number of biopsies,” ... “Would it not have made more
sense to appropriately increase the intensity and duration of exercise slowly
and then see if the subject’s bodies didn’t accommodate handling of ROS without
a significant change in induction of these markers?” ... The study reflects a
‘transient’ increase in ROS during ‘limited periods of physical exercise only’,
noted Dr Schauss, “whereas the bulk of the literature, including that in
non-primate models have not observed these concerns obtained in models of
‘continuous exposure to increased levels of ROS’” ... the authors presented no
evidence of adverse effects by any of the individuals from vitamin C and E

Antioxidant To Retard Wrinkles Discovered - Science Daily, 8/30/07 -
"Antioxidants operate against free radicals which cause
a breakdown of many tissues in the body, including the skin. When found in small
quantities in the body, free radicals are not harmful and are even involved in
various physical processes. When there is an excess of free radicals, however,
as occurs during normal aging or as a result of excessive exposure to
ultra-violet radiation from the sun, the result, among other things, is a
breakdown of the collagen and elastin fibers in the skin. When this happens,
there is a loss of skin elasticity and the formation of wrinkles ... A problem
with many of the commercial antioxidants found today in the market that are said
to retard the aging process is that they oxidize quickly and therefore their
efficiency declines with time"

Nutrition Can Help DNA
Repair in the Case of Aging - Nutrients 2020 Nov 1 -
"Micronutrients such as vitamins and trace elements are crucial for maintaining
the health of all organisms. Micronutrients are involved in every
cellular/biochemical process. They play roles in proper heart and brain
functioning, influence immunological responses, and antioxidant defense systems.
Therefore, prolonged deficiency in one or more micronutrients leads to
cardiovascular or neurodegenerative disorders. Keeping micronutrients at
adequate levels is especially important for seniors. They are prone to
deficiencies due to age-associated functional decline and often to a diet poor
in nutrients. Moreover, lack of micronutrients has an indirect impact on the
genome. Their low levels reduce the activity of antioxidant enzymes, and
therefore inhibit the efficiency of defense against free radicals which can lead
to the formation of DNA lesions. The more DNA damage in the genetic material,
the faster aging at the cellular level and a higher risk of pathological
processes (e.g., carcinogenesis). Supplementation of crucial antioxidative
micronutrients such as selenium, zinc, vitamin C, and vitamin E seems to have
the potential to positively influence the condition of an aging organism,
including minimizing inflammation, enhancing antioxidative defense, and limiting
the formation of DNA lesions. In consequence, it may lead to lowering the risk
and incidence of age-related diseases such as cardiovascular diseases,
neurodegenerative diseases, and malnutrition. In this article, we attempt to
present the synergistic action of selected antioxidant micronutrients (vitamin
C, vitamin E, selenium, and zinc) for inhibiting oxidative stress and DNA
damage, which may impede the process of healthy aging" - See

Dietary
antioxidants and periodontal disease in community-based older Japanese: a 2-year
follow-up study - Public Health Nutr. 2012 May 22:1-9 -
"Intakes of dietary antioxidants (vitamin C, vitamin E,
α-carotene and β-carotene) were assessed with a validated FFQ ... A higher
intake of dietary antioxidants was inversely associated with the number of teeth
with periodontal disease progression, controlling for other variables. The
multivariate-adjusted incidence rate ratios in the first, second and third
tertiles were 1.00, 0.76 (95 % CI 0.60, 0.97) and 0.72 (95 % CI 0.56, 0.93) for
vitamin C; 1.00, 0.79 (95 % CI 0.62, 0.99) and 0.55 (95 % CI 0.42, 0.72), for

Dietary
Antioxidant Intake is Associated with the Prevalence but not Incidence of
Age-Related Hearing Loss - J Nutr Health Aging. 2011;15(10):896-900 -
"We aimed to examine the link between dietary and
supplement intakes of antioxidants, and both the prevalence and 5-year incidence
of measured hearing loss ... participants aged 50+ at baseline, examined during
1997-9 to 2002-4 ... Dietary data were collected in a semi-quantitative food
frequency questionnaire ... each standard deviation (SD) increase in dietary
vitamin E intake was associated with a 14% reduced likelihood of prevalent
hearing loss, odds ratio, OR, 0.86 (95% confidence interval, CI, 0.78-0.98).
Those in the highest quintile of dietary vitamin A intake had a 47% reduced risk
of having moderate or greater hearing loss (>40 dB HL) compared to those in the
lowest quintile of intake, multivariable-adjusted OR 0.53 (CI 0.30-0.92), P for
trend = 0.04. However, dietary antioxidant intake was not associated with the

Dietary
total antioxidant capacity and gastric cancer risk in the european
prospective investigation into cancer and nutrition study - Int J
Cancer. 2011 Nov 9 - "A high intake of dietary
antioxidant compounds has been hypothesized to be an appropriate strategy to
reduce gastric cancer (GC) development. We investigated the effect of
dietary Total Antioxidant Capacity (TAC) in relation to GC in the European
Prospective Investigation into Cancer (EPIC) study including 23 centers in
10 European countries ... Dietary antioxidant intake is associated with a
reduction in the risk of GC for both FRAP (adjusted HR 0.66; 95%CI
(0.46-0.95) and TRAP (adjusted HR 0.61; 95%CI (0.43-0.87) (highest vs.
lowest quintile). The association was observed for both cardia and non
cardia cancers. A clear effect was observed in smokers with a significant
reduction in GC risk for the 5(th) quintile of intake for both assays
(highest vs. lowest quintile: adjusted HR 0.41; 95%CI (0.22-0.76) p for
trend <0.001 for FRAP; adjusted HR 0.52; 95%CI (0.28-0.97) p for trend
<0.001 for TRAP) but not in never smokers. In former smokers the association
with FRAP intake was statistically significant (highest vs. lowest quintile:

high use of garlic supplements (≥4 days/week for ≥3 years; HR=0.55 [95%
confidence interval: 0.34-0.87]; p=0.028 for trend) and ever use of grape
seed supplements (HR=0.57 [0.37-0.88]) were inversely associated with
hematologic malignancies in our models. In addition, high use (8-10
pill-years) of multivitamins was suggestive of an inverse association

French
adults' cognitive performance after daily supplementation with antioxidant
vitamins and minerals at nutritional doses: a post hoc analysis of the
Supplementation in Vitamins and Mineral Antioxidants (SU.VI.MAX) trial -
Am J Clin Nutr. 2011 Jul 20 - "This study included
4447 French participants aged 45-60 y who were enrolled in the SU.VI.MAX
study (1994-2002), which was a double-blind, placebo-controlled, randomized
trial. From 1994 to 2002, participants received daily vitamin C (120 mg),
β-carotene (6 mg), vitamin E (30 mg), selenium (100 μg), and zinc (20 mg) in
combination or as a placebo. In 2007-2009, the cognitive performance of
participants was assessed with 4 neuropsychological tests (6 tasks).
Principal components analysis (PCA) was performed to identify
cognitive-function summary scores. Associations between antioxidant
supplementation and cognitive functions, in the full sample and by
subgroups, were estimated through ANOVA and expressed as mean differences
and 95% CIs. Subgroup analyses were performed according to baseline
characteristics ... Subjects receiving active antioxidant supplementation
had better episodic memory scores (mean difference: 0.61; 95% CI: 0.02,
1.20). PCA indicated 2 factors that were interpreted as showing verbal
memory and executive functioning. Verbal memory was improved by antioxidant
supplementation only in subjects who were nonsmokers or who had low serum
vitamin C concentrations at baseline"

Simple sugar, lactate, is like 'candy for cancer cells': Cancer cells
accelerate aging and inflammation in the body to drive tumor growth -
Science Daily, 5/26/11 - "lactate is like "candy"
for cancer cells. And cancer cells are addicted to this supply of "candy."
... We've essentially shown for the first time that there is lactate shuttle
in human tumors ... If lethal cancer is a disease of "accelerated aging" in
the tumor's connective tissue, then cancer patients may benefit from therapy
with strong antioxidants and anti-inflammatory drugs ... Antioxidant therapy
will "cut off the fuel supply" for cancer cells." Antioxidants also have a
natural anti-inflammatory action"

Vitamin
supplement use during breast cancer treatment and survival: a prospective
cohort study - Cancer Epidemiol Biomarkers Prev. 2010 Dec 21 -
"Antioxidants may protect normal cells from the
oxidative damage that occurs during radiotherapy and certain chemotherapy
regimens, however, the same mechanism could protect tumor cells and
potentially reduce effectiveness of cancer treatments ... Vitamin use
shortly after breast cancer diagnosis was associated with reduced mortality
and recurrence risk, adjusted for multiple lifestyle factors,
sociodemographics, and known clinical prognostic factors. Women who used
antioxidants (vitamin E, vitamin C, multivitamins) had 18% reduced mortality
risk (hazard ratio (HR) = 0.82, 95% confidence interval (CI): 0.65-1.02) and
22% reduced recurrence risk (HR = 0.78, 95% CI: 0.63-0.95). The inverse
association was found regardless of whether vitamin use was concurrent or
non-concurrent with chemotherapy, but was only present among patients who
did not receive radiotherapy"

antioxidant potency composite index among the beverages tested and was at
least 20% greater than any of the other beverages tested. Antioxidant
potency, ability to inhibit LDL oxidation, and total polyphenol content were
consistent in classifying the antioxidant capacity of the polyphenol-rich
beverages in the following order: PJ > red wine > Concord grape juice >
blueberry juice > black cherry juice, açaí juice, cranberry juice > orange
juice, iced tea beverages, apple juice. Although in vitro antioxidant
potency does not prove in vivo biological activity, there is also consistent
clinical evidence of antioxidant potency for the most potent beverages
