Omega-3 Supplementation
Helps Meibomian Gland Dysfunction - Medscape, 4/20/15 -
"This study supports the potential of
omega-3 fatty acids to prevent
dry eye syndrome ... The prevalence of meibomian
gland dysfunction ranges from 30.3% to 63.3% and, in Asia, the prevalence is at
the top of that range ... The 30 patients in the treatment group took two
capsules of fish oil twice daily. The 1.2 g daily dose of omega-3 fatty acid
consisted of eicosapentaenoic acid 720 mg and docosahexaenoic acid 480 mg ...
The 30 patients in the placebo group took vitamin E 400 mg daily ... improvement
was seen in all measures of meibomian gland dysfunction in the two groups,
except the Schirmer's test, but changes were greater in the omega-3 group"

Oral
milk thistle extract stops colorectal cancer stem cells from growing tumors
- Science Daily, 4/20/15 - "It's very simple:
tumors from mice that were initially fed
silibinin had fewer cancer stem cells, were
smaller, had lower metabolisms and showed decreased growth of new blood vessels.
Importantly, when these cancer stem cells from tumors in mice fed silibinin were
re-injected into new mice, we found these stem cells had lost their potential to
repopulate even in the absence of silibinin exposure" - See

sprout extract promising for head and neck cancer prevention - Science
Daily, 4/19/15 - "People who are cured of
head and neck cancer are still at
very high risk for a second cancer in their mouth or throat, and, unfortunately,
these second cancers are commonly fatal ...
cruciferous vegetables that have a high concentration of sulforaphane ...
his team gave sulforaphane to mice predisposed to oral cancer and found that it
significantly reduced the incidence and number of tumors" - See

development suffers from lack of fish oil fatty acids, study finds - Science
Daily, 4/15/15 - "The findings suggest that women
maintain a balanced diet rich in these fatty acids for themselves during
pregnancy and for their babies after birth ...
These fatty acids are precursors of docosahexaenoic acid, or
DHA, which plays a key role in the healthy creation
of the central nervous system" - See
Jarrow Max DHA at Amazon.com Study: Acetaminophen reduces not only pain but pleasure - CNN.com, 4/15/15 - "acetaminophen, the main ingredient in Tylenol, most forms of Midol and more than 600 other medicines, reduces not only pain but pleasure, as well"
Mechanism outlined by which inadequate vitamin E can cause brain damage -
Science Daily, 4/13/15 - "that zebrafish fed a diet deficient in
vitamin E
throughout their life had about 30 percent lower levels of
DHA-PC, which is a
part of the cellular membrane in every brain cell, or neuron. Other recent
studies have also concluded that low levels of DHA-PC in the blood plasma of
humans is a biomarker than can predict a higher risk of
Alzheimer's disease ...
the deficient levels of vitamin E they were given, are equivalent to humans
eating a low vitamin E diet for a lifetime. In the United States, 96 percent of
adult women and 90 percent of men do not receive adequate levels of vitamin E in
their diet" - See

less focused on recurrent bad feelings when taking probiotics - Science
Daily, 4/14/15 - "Rumination is one of the most
predictive vulnerability markers of depression
... Compared to subjects who received the placebo intervention, participants who
received the multispecies probiotics intervention
showed significantly reduced ruminative thoughts ... Even if preliminary, these
results provide the first evidence that the intake of probiotics may help reduce
negative thoughts associated with sad mood. As such, our findings shed an
interesting new light on the potential of probiotics to serve as adjuvant
or preventive therapy for depression" - See

Plasma
carotenoids and risk of breast cancer over 20 y of follow-up - Am J Clin
Nutr. 2015 Apr 15 - "Higher concentrations of
α-carotene, β-carotene, lycopene, and total
carotenoids were associated with 18-28% statistically significant lower
risks of breast cancer (e.g., β-carotene top
compared with bottom quintile RR: 0.72; 95% CI: 0.59, 0.88; P-trend < 0.001).
Associations were apparent for total carotenoids measured ≥10 y before diagnosis
(top compared with bottom quintile RR: 0.69; 95% CI: 0.50, 0.95; P-trend = 0.01)
as well as those <10 y before diagnosis (RR: 0.79; 95% CI: 0.64, 0.98; P-trend =
0.04, P-interaction = 0.11). Carotenoid concentrations were strongly inversely
associated with breast cancer recurrence and death (e.g., β-carotene top
compared with bottom quintile RR: 0.32; 95% CI: 0.21, 0.51; P-trend < 0.001)
compared with not recurrent and not lethal disease" - See

Brain
atrophy in cognitively impaired elderly: the importance of long-chain ω-3 fatty
acids and B vitamin status in a randomized controlled trial - Am J Clin Nutr.
2015 Apr 15 - "included 168 elderly people (≥70 y) with mild cognitive
impairment, randomly assigned either to placebo (n = 83) or to daily high-dose
B
vitamin supplementation (folic acid, 0.8 mg; vitamin B-6, 20 mg; vitamin B-12,
0.5 mg) (n = 85). The subjects underwent cranial magnetic resonance imaging
scans at baseline and 2 y later ... In subjects with high baseline
ω-3 fatty
acids (>590 μmol/L), B vitamin treatment slowed the mean atrophy rate by 40.0%
compared with placebo (P = 0.023). B vitamin treatment had no significant effect
on the rate of atrophy among subjects with low baseline ω-3 fatty acids (<390
μmol/L). High baseline ω-3 fatty acids were associated with a slower rate of
brain atrophy in the B vitamin group but not in the placebo group" -

The effects
of probiotics on mental health and hypothalamic-pituitary-adrenal axis: A
randomized, double-blind, placebo-controlled trial in petrochemical workers
- Nutr Neurosci. 2015 Apr 16 - "divided into three
groups to receive 100 g/day probiotic yogurt + one placebo capsule (n = 25) or
one probiotic capsule daily + 100 g/day
conventional yogurt (n = 25) or 100 g/day conventional yogurt + one placebo
capsule (n = 20) for 6 weeks. Mental health parameters including general health
questionnaire (GHQ) and depression anxiety
and stress scale (DASS) scores were measured ... After 6 weeks of intervention,
a significant improvement of GHQ was observed in the probiotic yogurt (18.0 ±
1.5 vs. 13.5 ± 1.9, P = 0.007) and in the probiotic capsule group (16.9 ± 1.8
vs. 9.8 ± 1.9, P = 0.001), as well as a significant improvement in DASS scores
in the probiotic yogurt (23.3 ± 3.7 vs. 13.0 ± 3.7, P = 0.02) and the probiotic
capsule group (18.9 ± 3.2 vs. 9.4 ± 4.0, P = 0.006). However, there was no
significant improvement in the conventional yogurt group (P = 0.05 for GHQ and P
= 0.08 for DASS)" - See

Consuming Lentinula edodes
(Shiitake) Mushrooms Daily Improves Human Immunity: A Randomized Dietary
Intervention in Healthy Young Adults - J Am Coll Nutr. 2015 Apr 11:1-10 -
"Eating L. edodes for 4
weeks resulted in increased ex vivo proliferation of γδ-T (60% more, p < 0.0001)
and NK-T (2-fold more, p < 0.0001) cells. Both cell types also demonstrated a
greater ability to express activation receptors, suggesting that consuming
mushrooms improved cell effector function. The increase in sIgA implied improved
gut immunity. The reduction in CRP suggested lower inflammation. The pattern of
cytokines secreted before and after mushroom consumption was significantly
different; consumption resulted in increased interleukin (IL)-4, IL-10, tumor
necrosis factor (TNF)-α, and IL-1α levels, a decreased macrophage inflammatory
protein-1α/chemokine C-C ligand 3 (MIP-1α/CCL3) level, and no change to IL-6,
IL-1β, MIP-1β, IL-17 and interferon (IFN)-γ levels" - [Science

Carotenoid
intakes from natural sources and head and neck cancer: a systematic review and
meta-analysis of epidemiological studies - Cancer Epidemiol Biomarkers Prev.
2015 Apr 14 - "meta-analysis of the epidemiological
studies ... The risk reduction associated with β-carotene equivalents intake was
46% (95% CI: 20-63%) for cancer of oral cavity and 57% (95% CI: 23-76%) for
laryngeal cancer. Lycopene and β-cryptoxanthin also reduced the risk for
laryngeal cancer; the ORs for the highest category compared to the lowest one of
carotenoid intake were 50% (95% CI: 11-72%) and 59% (95% CI: 49-67%),
respectively. Lycopene, α-carotene, and β-cryptoxanthin were associated with at
least 26% reduction in the rate of oral and pharyngeal cancer (95% CI: 2-44%).
Our systematic-review and meta-analysis on dietary carotenoids intake and HNC
showed carotenoids to act protectively
against HNC, in relation to most of
single-nutrients and subsites" - See

Dietary
vitamin D3 improves postprandial hyperglycemia in aged mice - Biochem
Biophys Res Commun. 2015 Apr 10 - "Recent observational
and randomized studies on vitamin D3 suggested
that higher plasma 25-hydroxyvitamin D3 [25(OH)D3] concentrations and more
vitamin D3 intake are associated with lower risk of type 2
diabetes, which is characterized by
postprandial hyperglycemia due to inappropriate glucose stimulated insulin
secretion (GSIS) and its age-dependent increase of onset ... When vitamin D3 is
orally ingested in mice aged 12-14 weeks during an oral glucose tolerance test
(OGTT), the serum glucose profile was not changed. In contrast, when OGTT was
performed with old mice aged 30-34 weeks, the glucose profile was dramatically
improved with increased insulin secretion, suggesting that orally ingested
vitamin D3 potentiated GSIS in aged mice. Interestingly, there was also a
significant increase in plasma GLP-1 in these aged mice" - See

If you're the type of person who's always cashing in on AppleCare, we suggest something with more protection, such as Speck's CandyShell ($35), our previous top pick ... If you'd rather not carry a phone and a wallet, we recommend CM4's Q Card Case ($40). The body is sturdy rubber and fits securely, protruding in front to form a 0.8-mm screen lip. On the back, there's a faux-leather pocket that can hold up to three cards, plus some cash" - Note: The wallet one might be the thing of the future. With Apple Pay you may not need the credit cards. Just carry your drivers license and a couple of $20's. Carry the old wallet in your car glove compartment if you ever need it. Health Focus (Triglycerides).
