Blueberries, grapes and apples lnked to reduced risk of type 2 diabetes
Posted on August 29, 2013 by Stone Hearth News
Eating more whole fruits, particularly blueberries, grapes and apples, is associated with a lower risk of type 2 diabetes, with greater fruit juice consumption having an adverse effect, a paper published today on bmj.com suggests. Increasing fruit consumption has been recommended for the prevention of many chronic diseases, including type 2 diabetes. However, studies have generated some mixed results.
Researchers from the UK, USA and Singapore therefore looked to examine the association of individual fruit consumption in relation to type 2 diabetes risk. Data were used from three prospective cohort studies among US adults: the Nurses’ Health Study (NHS 1984 – 2008), the Nurses’ Health Study II (NHS II 1991-2009) and the Health Professionals Follow-up Study (HPFS 1986 – 2008).
There were 187,382 participants totaling 3,464,641 years of follow-up. The study included both men and women (151,209 women and 36,173 men). Participants who reported a diagnosis of diabetes, cardiovascular disease or cancer at baseline were excluded.
Ten individual fruits were used in the study: grapes or raisins; peaches, plums or apricots; prunes; bananas; cantaloupe; apples or pears; oranges; grapefruit; strawberries; blueberries. Fruit juice included apple; orange; grapefruit and other fruit juices. Food frequency questionnaires were used every four years to assess participants’ habitual diet, asking how often, on average, they consumed each food in a standard portion size. Participants could choose from nine possible responses, ranging from “never, or less than once per month” to “six or more times per day”.
Information was gathered on participants’ body height and weight, cigarette smoking, physical activity, multivitamin use and family history of diabetes. Information for women was collected on menopausal status, post-menopausal hormone use and oral contraceptive use.
Results showed that 12,198 out of 187,382 (6.5%) participants developed diabetes
Total whole fruit consumption correlated positively with age, physical activity, multivitamin use, total energy intake and fruit juice consumption. Three servings per week of blueberries; grapes and raisins; apples and pears significantly reduced the risk of type 2 diabetes.
In contrast, greater consumption of fruit juice was associated with increased type 2 diabetes risk. Substitution of whole fruits for fruit juice was associated with a lower risk, except strawberries and cantaloupe melon.
Results showed that 12,198 out of 187,382 participants developed diabetes so the overall risk in the populations studied over many years was 6.5%. Among those who had three servings per week of individual whole fruits rather than fruit juice the overall risk was itself reduced by 7%.
Replacing three servings per week of fruit juice with individual whole fruits reduced the risk of type 2 diabetes by 7%.
The researchers conclude that there is a significant difference in the associations between individual fruits and the risk of type 2 diabetes and that greater consumption of specific whole fruits “particularly blueberries, grapes and apples was significantly associated with lower type 2 diabetes risk whereas greater fruit juice consumption was associated with a higher risk”. They say the results support recommendations to increase the consumption of a variety of whole fruits as a measure for diabetes prevention.

Doubling the daily allowance of protein intake with diet and exercise protects muscle loss
Posted on August 29, 2013 by Stone Hearth News
Bethesda, MD—A new report appearing in the September issue of The FASEB Journal challenges the long-held adage that significant muscle loss is unavoidable when losing weight through exercise and diet.
In the report, scientists show that consuming twice the recommended daily allowance (RDA) of protein while adhering to a diet and exercise plan prevents the loss of muscle mass and promotes fat loss.
Tripling the RDA of protein, however, failed to provide additional benefits.
“It is our hope that the findings from this well-controlled study will be discussed and cited by the Institute of Medicine for the updated Dietary Reference Intakes on protein,” said Stefan M. Pasiakos, Ph.D., a researcher involved in the work from the Military Nutrition Division at the U.S. Army Research Institute of Environmental Medicine in Natick, MA.
“We believe that the RDA for protein should be based on a level to optimize health, as well as prevent deficiencies, and our data demonstrate a potential inadequacy of the current RDA for sparing muscle mass during weight loss, which may affect a significant portion of the population.”
To make this discovery, Pasiakos and colleagues assigned young men and women controlled diets for 31 days that provided dietary protein at three different levels:
- 1) the U.S. RDA,
- 2) twice the U.S. RDA,
- and
- 3) three times the U.S. RDA.
Volunteers were given adequate total calories to maintain constant body weight for the first 10 days to allow their metabolism to adapt to the dietary protein level, and then for the following three weeks, weight loss was induced by restricting the total calories and increasing daily exercise sufficiently to elicit an average two-pound weight loss per week.
All meals were prepared and administered by research staff and exercise was highly controlled. Body composition and measurements of muscle protein metabolism were performed at the end of both the stable weight maintenance and weight loss phases of the study.
Results of this study demonstrated that there are limits to the protective effect of extra protein.
As such, these data suggest an optimal, and perhaps maximal, level of protein for young, active adults who may undergo short-term periods of intentional or unintentional weight loss.
“This study essentially confirms what body builders have shown us for a long time—a high protein diet helps prevent muscle loss when trying to lose fat,” said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal.
“Although eating a well balanced diet is still necessary for health and weight maintenance, upping one’s protein intake when dieting might be a useful tool in the short term.”

7 things to know about omega-3 fatty acids
Here are 7 things you should know about omega-3s:
- Results of studies on diets rich in seafood (fish and shellfish) and heart disease provide moderate evidence that people who eat seafood at least once a week are less likely to die of heart disease than those who rarely or never eat seafood. The Dietary Guidelines for Americans, 2010 (3MB PDF) includes a new recommendation that adults eat 8 or more ounces of a variety of seafood per week because it provides a range of nutrients, including omega-3 fatty acids. (Smaller amounts are recommended for young children, and there are special recommendations for pregnant or breastfeeding women. See Tip #4.)
- Evidence suggests that seafood rich in EPA and DHA should be included in a heart-healthy diet; however, supplements of EPA and DHA have not been shown to protect against heart disease. In 2012, two groups of scientists analyzed the research on the effects of EPA/DHA supplements on heart disease risk. One group analyzed only studies in people with a history of heart disease, and the other group analyzed studies in people both with and without a history of heart disease. Neither review found strong evidence of a protective effect of the supplements.
- A 2012 review of the scientific literature concluded that EPA and DHA, the types of omega-3s found in seafood and fish oil, may be modestly helpful in relieving symptoms of rheumatoid arthritis. In the studies included in the review, many of the participants reported that when they were taking fish oil they had briefer morning stiffness, less joint swelling and pain, and less need for anti-inflammatory drugs to control their symptoms.
- The nutritional value of seafood is of particular importance during fetal growth and development, as well as in early infancy and childhood. Women who are pregnant or breastfeed should consume 8 to 12 ounces of seafood per week from a variety of seafood types that are low in methyl mercury as part of a healthy eating pattern and while staying within their calorie needs. Pregnant or breastfeeding women should limit the amount of white tuna (labeled as “albacore”) to no more than 6 ounces per week. They should not eat tilefish, shark, swordfish, and king mackerel because they are high in methyl mercury.
- There is ongoing research on omega-3 fatty acids and diseases of the brain and eye, but there is not enough evidence to draw conclusions about the effectiveness of omega-3s for these conditions. DHA plays important roles in the functioning of the brain and the eye. Researchers are actively investigating the possible benefits of DHA and other omega-3 fatty acids in preventing or treating a variety of brain- and eye-related conditions.
- There is conflicting evidence about whether a link might exist between the omega-3 fatty acids found in seafood and fish oil (EPA/DHA) and an increased risk of prostate cancer. Additional research on the association of omega-3 consumption and prostate cancer risk is under way.
- The bottom line: Including seafood in your diet is healthful. Whether omega-3 supplements are beneficial is uncertain. If you are considering omega-3 supplements, talk to your health care provider. It’s especially important to consult your (or your child’s) health care provider if you are pregnant or breastfeeding, if you take medicine that affects blood clotting, if you are allergic to seafood, or if you are considering giving a child an omega-3 supplement.

Acute exercise enhances preschoolers’ ability to sustain attention.

Abstract
A growing body of research has illuminated beneficial effects of a single bout of physical activity (i.e., acute exercise) on cognitive function in school-age children.
However, the influence of acute exercise on preschoolers’ cognitive function has not been reported.
To address this shortcoming, the current study examined the effects of a 30-min bout of exercise on preschoolers’ cognitive function. Preschoolers’ cognitive function was assessed following a single bout of exercise and a single sedentary period.
Results revealed that, after engaging in a bout of exercise, preschoolers exhibited markedly better ability to sustain attention, relative to after being sedentary (p = .006, partial eta square = .400).
Based on these findings, providing exercise opportunities appears to enhance preschoolers’ cognitive function.

Abstract
BACKGROUND:
Low muscle strength is related to an increased risk for several chronic diseases. Increased muscle strength improves daily function and quality of life.
OBJECTIVE:
To measure maximal step-up height, an assessment of leg strength and function, and its association to age, anthropometric variables, maximal oxygen uptake (VO2-max) and self-reported physical function before and after a physical activity program.
METHODS:
Female patients (n=178, 22-83 years) with musculoskeletal disorders, metabolic risk factors and other chronic diseases were recruited from primary care. Maximal step-up height (standardised step-up without a kick-off with the floor foot), anthropometric variables, VO2-max and self-reported physical function (Short Form 36 (SF-36)) were assessed before and after a 3-month group training intervention programme. Associations between maximal step-up height and other variables were examined using univariate and multivariate methods.
RESULTS:
At baseline and after intervention, maximal step-up height was negatively correlated to age, waist circumference and body weight and positively correlated to VO2-max, self-reported physical function and height. Furthermore, maximal step-up height correlated to training intensity at follow-up. Variations in changes in maximal step-up height were significantly explained by changes in waist circumference and physical function, regardless of age and changes in VO2-max. Maximal step-up height below 24 cm discriminated patients with self-reported severe limitation in physical function.
CONCLUSIONS:
Maximal step-up height, assessed simply with a standardised step-up test, may function as a relevant indicator of health since it correlated negatively to the metabolic risk factors, waist circumference, body weight and age, and positively to VO2-max and physical function.

Abstract
Body weight (BW) and blood pressure (BP) have a close relationship, which has been accounted for by hormonal changes.
No previous study has evaluated the effect of wearing an external weight vest on BP to determine whether there is a simple mechanism between BW and BP. Seventeen healthy volunteers underwent weight reduction (WR) through caloric restriction.
Before and after WR, BW, body fat percentage and BP at rest and during exercise were measured.
Before and after WR, exercise testing was performed twice with the random allocation of a weight vest (10 kg) during one of the tests.
Linear regression was used to detect independent associations between BP and the weight vest, BW and body fat percentage. BW decreased from 89.4±15.4 kg to 79.1±14.0 kg following WR (P<0.001).
WR led to significant decreases in BP at rest (from 130.0/85.9 mm Hg to 112.5/77.8 mm Hg, P

Exercise is medicine: some cautionary remarks in principle as well as in practice.

Abstract
On the basis of extensive research on the relationship between physical activity, exercise and health, as well as strong support from policymakers and practitioners, the “Exercise is Medicine” initiative has become something of a linchpin in the agenda for modern healthcare reform and reflects a broader acceptance that the philosophy of health politics must shift from social engineering to performativity.
However, in spite of the avowed commitment to encouraging individuals to take on a more reflexive relation to their health, it remains unclear as to whether an initiative such as this is, unambiguously, a good thing.
In this paper, a number of cautionary remarks are made with respect to “Exercise is Medicine” in principle as well as in practice.
Firstly, it is argued that equating exercise with medicine is to equate it with a definition of and relation to the body to which it is not entirely akin.
And secondly, it is argued that any proposed alignment of the fitness and healthcare industries needs further critical examination, a realigning of interests, and a thorough reconsideration of their suitability of fit.

Abstract
OBJECTIVE
The purpose of this study was to determine the effect of a relatively modest session of exercise on insulin sensitivity and fatty acid uptake the next day in obese adults.
RESEARCH DESIGN AND METHODS
Eleven sedentary obese adults (male/female: 3/8; BMI 37 ± 1 kg/m2; peak oxygen uptake [VO2peak] 20 ± 1 mL/kg/min) completed three experimental trials. On two of these occasions, subjects exercised to expend 350 kcal in the afternoon. These two exercise trials were identical except for the exercise intensity (50% VO2peak [EX50] and 65% VO2peak [EX65]) and the duration of exercise necessary to expend 350 kcal (EX50 = ∼70 min; EX65 = ∼55 min). Subjects also completed a control trial (CON), without exercise. The next morning, we measured insulin sensitivity (hyperinsulinemic-euglycemic clamp) and whole-body fatty acid uptake (palmitate rate of disappearance from plasma [Rd]).
RESULTS
Exercise increased insulin sensitivity the next day, but whereas the 35% improvement after EX50 compared with CON was statistically significant (P = 0.01), the 20% improvement after EX65 was not (P = 0.17). Despite nearly identical values between CON and EX65 (P = 0.88), systemic fatty acid uptake was lower after EX50 compared with EX65 (P = 0.02), but not quite significant compared with CON (P = 0.07). Importantly, the change in fatty acid uptake after exercise compared with CON was negatively correlated with the change in insulin sensitivity for all trials (r = −0.60, P = 0.003).
CONCLUSIONS
A relatively modest single session of exercise in obese adults improved insulin sensitivity the next day, and a reduction in systemic fatty acid uptake in the several hours after exercise may be important for this effect.

Abstract
Objectives
To analyse the association between dietary long-chain n-3 polyunsaturated fatty acids (PUFAs) and incidence of rheumatoid arthritis (RA) in middle-aged and older women from the Swedish Mammography Cohort, a population-based prospective study.
Methods
Data on diet were collected in 1987 and 1997 via a self-administered food-frequency questionnaire (FFQ). The risk of RA associated with dietary long-chain n-3 PUFAs and fish intake was estimated using Cox proportional hazard regression models, adjusted for age, cigarette smoking, alcohol intake, use of aspirin and energy intake.
Results
Among 32 232 women born 1914–1948, 205 RA cases were identified during a mean follow-up of 7.5 years (1 January 2003 to 31 December 2010; 2 41 120 person-years). An intake of dietary long-chain n-3 PUFAs (FFQ1997) of more than 0.21 g/day (lowest quintile) was associated with a 35% decreased risk of developing RA (multivariable adjusted relative risk (RR) 0.65; 95% CI 0.48 to 0.90) compared with a lower intake. Long-term intake consistently higher than 0.21 g/day (according to both FFQ1987 and FFQ1997) was associated with a 52% (95% CI 29% to 67%) decreased risk. Consistent long-term consumption (FFQ1987 and FFQ1997) of fish ≥1 serving per week compared with <1 was associated with a 29% decrease in risk (RR 0.71; 95% CI 0.48 to 1.04).
Conclusions
This prospective study of women supports the hypothesis that dietary intake of long-chain n-3 PUFAs may play a role in aetiology of RA.

Abstract
Background:
The specific effects of fruit and vegetable (F&V) intake on water balance and consequently on 24-h hydration status (HS) are unknown.
Objectives:
In a large observational cohort of German children, we examined whether a higher F&V intake per se is associated with improved HS and attempted to quantify the influence of greater consumption of F&Vs on HS.
Design:
A total of 1286 complete 3-d weighed dietary records and 24-h urine samples for 442 children (4- to 10-y-olds) collected in 2000–2010 in the Dortmund Nutritional and Anthropometric Longitudinally Designed Study were analyzed. Free water reserve [FWR; urine volume (mL/24 h) minus obligatory urine volume (mL/24 h)] served as an HS biomarker. Median FWR and water balance variables were analyzed in different categories of solid-F&V intakes. Repeated-measures regression models (PROC MIXED; SAS Institute), adjusted for all other dietary water sources, were used to quantify the separate effects of solid-F&V and F&V-juice consumption on FWR.
Results:
Negative FWR values, which indicated risk of hypohydration, were observed in 22% of children. FWR was significantly higher in solid-F&V consumers with high intakes than in those with low intakes (P < 0.0001). PROC MIXED models predicted an increase of 46 mL in FWR (average in boys and girls) when increasing solid-F&V intake by 100 g. Similar results were observed for F&V juice (β = 43, P < 0.0001). Drinking water and milk were the other significant dietary predictors of FWR. Solid F&Vs and F&V juices contributed 12% and 10%, respectively, to total water intake.
Conclusions:
These data confirm that regular intake of F&Vs may relevantly improve HS in children. Dietary interventions to increase F&V intake may be a promising strategy to achieve positive water balance in this population.

Abstract
BACKGROUND:
Mind-body medical interventions are commonly used to cope with depression and yoga is one of the most commonly used mind-body interventions. The aim of this review was to systematically assess and meta-analyze the effectiveness of yoga for depression.
METHODS:
Medline/PubMed, Scopus, the Cochrane Library, PsycINFO, and IndMED were searched through January 2013. Randomized controlled trials (RCTs) of yoga for patients with depressive disorders and individuals with elevated levels of depression were included. Main outcomes were severity of depression and remission rates, secondary outcomes were anxiety, quality of life, and safety.
RESULTS:
Twelve RCTs with 619 participants were included. Three RCTs had low risk of bias. Regarding severity of depression, there was moderate evidence for short-term effects of yoga compared to usual care (standardized mean difference (SMD) = -0.69; 95% confidence interval (CI) -0.99, -0.39; P < .001), and limited evidence compared to relaxation (SMD = -0.62; 95%CI -1.03, -0.22; P = .003), and aerobic exercise (SMD = -0.59; 95% CI -0.99, -0.18; P = .004). Limited evidence was found for short-term effects of yoga on anxiety compared to relaxation (SMD = -0.79; 95% CI -1.3, -0.26; P = .004). Subgroup analyses revealed evidence for effects in patients with depressive disorders and in individuals with elevated levels of depression. Due to the paucity and heterogeneity of the RCTs, no meta-analyses on long-term effects were possible. No RCT reported safety data.
CONCLUSIONS:
Despite methodological drawbacks of the included studies, yoga could be considered an ancillary treatment option for patients with depressive disorders and individuals with elevated levels of depression.

Abstract
PURPOSE:
The purpose of this study was to investigate the effect of repeated bouts of eccentric exercise on the nociceptive withdrawal reflex (NWR) threshold, a measure of sensitivity in the spinal nociceptive system.
METHODS:
Sixteen healthy students (age 25.7 ± 0.6 years, BMI 24.8 ± 1 kg m-2) participated in this randomized, controlled, crossover study. Two identical bouts of high-intensity eccentric exercises were performed on the tibialis anterior muscle 7 days apart. Control sessions involving no exercise were performed 4 weeks apart the exercise sessions. Pressure pain thresholds (PPT) and the NWR threshold were recorded before, immediately after, and 1 day after both bouts of exercise.
RESULTS:
Pressure pain thresholds decreased significantly at two of the muscle belly sites on the day after initial bout compared with baseline. NWR threshold decreased by 25 ± 4 % immediately after initial bout and by 30 ± 5 % the next day (p < 0.05) as an indication of generalized pain hypersensitivity. On the contrary, no changes were found in both pain thresholds after second bout of eccentric exercise indicating that both localized and generalized pain sensitivity were normalized.
CONCLUSION:
In conclusion, this study for the first time documented that an initial bout of unaccustomed high-intensity eccentric exercise, which results in muscle soreness can induce central sensitization. A repeated bout of exercise, however, facilitates inherent protective spinal mechanisms against the development of muscle soreness.

Abstract
BACKGROUND/AIM:
Resistance training is an exercise modality at which overweight and obese adolescents can excel and which can therefore positively affect their psychological well-being. The aim of this study was to determine the effect of a 6-month resistance training intervention on the self-concept strength and body composition of overweight and obese adolescent males.
METHODS:
56 overweight and obese males aged 13-17 years were randomly allocated to an Intervention (n=30) or Control (n=26) group. Primary (psychological) and secondary (strength and body composition) outcomes were assessed at baseline as well as at 3 (halfway through the intervention), 6 (immediately postintervention) and 12 months follow-up. Random effects mixed modelling was used to determine the effects of the intervention.
RESULTS:
Statistically significant differences between the Intervention and Control groups were observed at 3-month and 6-month assessments for exercise self-efficacy, resistance training confidence and self-esteem. Large increases in strength for the Intervention group, relative to Controls, were also observed with no substantial changes in body composition shown for either group. Values for all variables returned to baseline following completion of the programme.
CONCLUSIONS:
A 6-month resistance training intervention can positively affect the self-concept and strength of overweight and obese adolescent boys.

Abstract
This study investigated the associations of personal goals with exercise activity as well as the relationships between exercise-related and other personal goals among older women.
Both cross-sectional and longitudinal design was used with a sample of 308 women aged 66 to 79 years at baseline.
Women who reported exercise-related personal goals were four times more likely to report high exercise activity at baseline compared to those who did not report exercise-related goals.
Longitudinal results were parallel.
Goals related to cultural activities as well as to busying oneself around home coincided with exercise-related goals, while goals related to own and other people’s health and independent living lowered the odds of having exercise-related goals.
Helping older adults to set realistic exercise-related goals that are compatible with their other life goals may yield an increase in their exercise activity, but this should be evaluated in a controlled trial.

Inaugural

premiere, Wednesday, September 4 at 10 p.m. ET
Thirty-two
bantamweight fighters compete for 16 exclusive spots and a chance to work with

Las Vegas, Nev. –
On Wednesday, Sept. 4, history will be made as the Ultimate Fighting
Championship®’s long-running reality series, The Ultimate Fighter®,
makes its debut on America's new sports network, FOX Sports 1. UFC women’s
bantamweight champion Ronda
Rousey and No.1 title contender Miesha Tate serve as coaches
in the first ever season to feature women as coaches and cast members. The
Ultimate Fighter®: Team Rousey vs. Team Tate kicks off with
a two-hour premiere beginning at 10 p.m. ET.
In this 18th
edition of the series, 16 men and 16 women bantamweight (135 lbs.) fighters
will face off in the most challenging sports tournament on television. The
premiere episode will determine the eight men and eight women who will
successfully move into The Ultimate Fighter house and compete for a
Harley Davidson motorcycle and a six-figure contract with the UFC®.

The successful fighters will
then be divided into two teams, coached by Rousey and Tate respectively. The
series will follow the teams as they live and train together in preparation for
their fights. The coaches will then face off in the Octagon® for the
women’s bantamweight title on Saturday, Dec. 28,
at UFC® 168: WEIDMAN vs. SILVA at the MGM Grand Hotel
& Casino in Las Vegas.
“This season of The
Ultimate Fighter was monumental, as we had women as coaches and competitors
– fighting and living together with the men – for the first time ever,” UFC
president Dana White said. “Obviously the fierce rivalry between Ronda and
Miesha is going to get everyone’s attention, but it doesn’t take away from
their dedication and success as coaches and the level of talent this season.
One of the things that always makes The Ultimate Fighter great is the
fights, and this season continues to deliver. Since we added the women’s
division earlier this year, they’ve been putting on awesome fights, and the
streak continues on the show, giving the men some serious competition and
setting up some Fight-of-the-Night worthy battles.”
"FOX Sports 1 is now
the exclusive home of the UFC. To have a show that packs this kind of power and
gives our viewers a raw, emotional look into becoming an MMA professional is
reality television at it's best. We can't wait for the September
4th premiere," said FOX Sports 1 Co-president Eric Shanks.
The Ultimate Fighter®:
Team Rousey vs. Team Tate will anchor FOX Sports 1’s UFC
Wednesday block and run for 13 weeks. Each episode’s winners will advance in
the single-elimination tournament, which will culminate in a three-hour finale,
live from the Mandalay Bay Events Center in Las Vegas on Saturday, November 30.
Tickets set to go on sale to the public on October 11.
