Older adults: Double your protein to build more muscle - Science Daily, 1/30/15 - "Current US recommendations for daily dietary protein intake are 0.8 grams/kilogram of body weight (roughly 62 g of protein per day for a 170-pound person). Previous research has shown that older adults need a protein intake of at least 0.40 g/kg of body weight at each meal (roughly 31 g of protein per meal or 93 g per day for a 170-pound person) to encourage maximum protein synthesis. This represents a significantly higher amount of protein than the recommended dietary allowance (RDA) suggests ... The research team studied 20 healthy adults between 52-75 years of age, randomly assigning them to one of four groups over a four-day test period ... while the distribution of protein across meals did not make a significant impact, total amount of protein consumed" Totality of trials data confirm Tamiflu reduces length of symptoms, complications, and hospital admissions from influenza - Science Daily, 1/30/15 - "oseltamivir significantly reduces the risk of influenza complications requiring antibiotics (such as pneumonia) and hospitalisations in adults infected with influenza ... treating adults with laboratory-confirmed influenza with oseltamivir reduced the duration of symptoms by 21% compared with placebo (from 123 hours to 98 hours) ... oseltamivir reduced the risk of lower respiratory tract infections requiring antibiotics more than 48 hours after study entry by 44% compared with placebo (4.9% vs 8.7%), and hospital admission for any cause by 63% (0.6% vs 1.7%) in adults with laboratory-confirmed influenza"

Reduced Pain in Knee Arthritis in RCT - Medscape, 1/30/15 -
"a combination glucosamine/chondroitin
sulfate product produced a 50.1% decrease in Western Ontario and McMaster

Pharmacological Potential
of Tocotrienols: A Review - Medscape, 1/29/15 - "In
contrast to αT, despite no evidence that deficiency of other
vitamin E forms
would result in obvious clinical symptoms, accumulating evidence suggests that
γT, δT, and tocotrienols seem to have unique properties that are superior to αT
and relevant to prevention and therapy against chronic diseases even under
conditions with adequate αT status. It is noteworthy that these bioactivities of
tocopherols and tocotrienols including anti-inflammatory properties have been
identified by mechanistic studies and subsequently substantiated in some
preclinical models as well as clinical studies ... Hence, tocotrienols possess neuroprotective, antioxidant, anti-cancer and cholesterol lowering properties.
Tocotrienols are thought to have more potent antioxidant and free radical
scavenging properties due to their better distribution in the lipid layers of
the cell membrane. In spite of the promising potential, the experimental
analysis of tocotrienols accounts for only a small portion of vitamin E
research" - See

Our results also showed that patients who continued to use cannabis had worse outcomes than those who either stopped using cannabis or had never used it ... patients that continued using cannabis had more suicide attempts than those that quit or those who never used cannabis" Researchers find hormone that increases the sex drive of mice - Science Daily, 1/27/15 - "when mice receive a supplement of ghrelin, they increase their sexual activity and their efforts to find a partner" - Note: It doesn't sound like a cure to me. Ghrelin is the hunger hormone. So you pack on the pounds, plugging up your arteries and you're back where you started. Plus it may have just been the increase in calories that caused the increase in sexual activity in the first place.
Many
U.S. consumers do not use a food thermometer when cooking poultry, despite
hazardous risks - Science Daily, 1/16/15 - "fewer than two-thirds of
consumers own a food thermometer, and less than 10 percent of food thermometer
owners actually use it to check for doneness of all types of poultry ...
Pathogens, such as Salmonella and Campylobacter, may be present on raw poultry.
Using a food thermometer is the only reliable way to ensure food is cooked to a
safe internal temperature to destroy any harmful bacteria that may present. USDA
recommends that consumers cook all poultry to a safe minimum internal
temperature of 165°F" - Note: I was surprise that the number that use them
is so few. Here's my favorite. It's simple and easy to read: MeasuPro DCT250 Ultra-Fast Instant Read Digital Cooking Thermometer with Timer, Silver Abstracts from this week:

Probiotic
supplementation prevents high-fat, overfeeding-induced insulin resistance in
human subjects - Br J Nutr. 2015 Jan 29:1-7 - "The
purpose of the present study was to determine whether
probiotic supplementation (Lactobacillus casei Shirota (LcS)) prevents
diet-induced insulin resistance in human subjects. A total of seventeen healthy
subjects were randomised to either a probiotic (n 8) or a control (n 9) group
... Glucose AUC values increased by 10 % (from 817 (se 45) to 899 (se 39) mmol/l
per 120 min, P< 0.05) and whole-body insulin sensitivity decreased by 27 % (from
5.3 (se 1.4) to 3.9 (se 0.9), P< 0.05) in the control group, whereas normal
insulin sensitivity was maintained in the probiotic group (4.4 (se 0.8) and 4.5
(se 0.9) before and after overeating, respectively (P>0.05). These results
suggest that probiotic supplementation may be useful in the prevention of

Here we show that this mechanism may be immune-mediated. Metformin enabled normal but not T-cell-deficient SCID mice to reject solid tumors. In addition, it increased the number of CD8+ tumor-infiltrating lymphocytes (TILs) and protected them from apoptosis and exhaustion characterized by decreased production of IL-2, TNFα, and IFNγ. CD8+ TILs capable of producing multiple cytokines were mainly PD-1-Tim-3+, an effector memory subset responsible for tumor rejection" - See metformin at The Antiaging Store.
