Higher dietary fiber intake is linked to reduced body weight
One particular cohort study, published in the American Journal of Clinical Nutrition, included 89,432 European participants, aged 20–78 years, who were initially free of cancer, cardiovascular disease, and diabetes. Participants were followed for an average of 6.5 years. Results indicated that total dietary fiber intake was inversely associated with weight and change in waist circumference during the study period. At 10 grams/day higher total fiber intake, there was an estimated 39 grams/year weight loss and waist circumference decreased by 0.08 cm/year. A 10 grams/day fiber intake from cereals alone results in 77 grams/year weight reduction and 0.10 cm/year reduction in waist circumference. Fruit and vegetable fiber was not associated with weight change but had an effect similar to total and cereal fiber intake on reduced waist circumference.
In another study, a review article published in the journal Nutrition suggests that dietary fiber helps prevent obesity in several different ways. It promotes satiation by slowing gastric emptying, altering glycemic or insulin response, decreasing absorption of macronutrients, and by altering the secretion of gut hormones linked to hunger.
Over the last decade many the most popular weight-loss diets have trended towards high-protein and low-carbohydrate intakes to lose weight. Unfortunately, in an effort to lower carbohydrate intake, these diets often have very low fiber intake as well. Analysis of low carbohydrate diets reveal that in some cases dietary fiber intake is as low as 1.6 grams/day and is almost always less than 10 grams/day.
The author of this review suggests that regardless of dieting method that individuals choose to follow, they should consider the addition of fiber to aid their weight-loss. Dietary fiber can be increased through increasing consumption fruits, vegetables, whole grains, legumes, or through a fiber supplement.

High-intensity exercise may influence appetite regulation and food selection
At a Glance
Increased physical activity is associated with long-term successful weight maintenance due to mechanisms more complex than just increased energy expenditure. A study using MRI imaging has shown that intense exercise not only affects energy output, but may also influence how people respond to food.
Read more about this research below.
Short periods of intense exercise are known to suppress hunger through appetite regulating hormones. A study published in the American Journal of Clinical Nutrition compared the effects of high-intensity exercise on central (brain) response to visual food stimuli.
The researchers recruited 15 healthy lean men in their early twenties. The study participants completed two 60 minute tests: exercise (running at 70% maximum aerobic capacity) and a resting control. After each test, images of high- and low- calorie foods were viewed and the brain response to the foods was measured using an MRI.
After the exercise session, thirst and core body temperature were increased while appetite response was significantly suppressed. Exercise significantly suppressed ghrelin (an appetite stimulating hormone) and enhanced the release of peptide YY (an appetite reducing hormone). When compared to the resting control, neural (brain) response in the brain’s reward related regions were stimulated in response to viewing the images of low-calorie foods, but suppressed upon viewing images of high-calorie foods.
This study found that high intensity exercise increases neural responses in reward-related regions of the brain in response to images of low-calorie foods, and suppresses activation during the viewing of high-calorie foods. These central responses are associated with exercise-induced changes in peripheral signals related to hydration and appetite-regulation.
Exercise is a well-known important component of a healthy lifestyle. This study provides further evidence that exercise can do more than just providing a caloric deficit, it may also influence you to make healthier food choices.

Vitamin E status in women and the risk of miscarriage in early pregnancy
Vitamin E status in women and the risk of miscarriage in early pregnancy
|
At a Glance A new study has found that maternal vitamin E status during the first trimester of pregnancy may influence the risk of early miscarriage in women. Read more about this research below. |
Originally
tocopherols were discovered for their role in animal reproduction, but
little to date has been known about the contribution of vitamin E
deficiencies in human pregnancy loss. A new study published in the American Journal of Clinical Nutrition
has shown that maternal vitamin E status in the first trimester may
influence the risk of early pregnancy loss. This is believed to be the
first population study of early pregnancy vitamin E nutritional status
and the risk of miscarriage in a human population.
The study was conducted in rural Bangladesh, a typically undernourished population. The researchers measured alpha-tocopherol and gamma-tocopherol plasma status of a case-cohort study of 1,605 pregnant Bangladeshi women. 1,161 of the women (72.3%) had low-to-deficient vitamin E status defined by a plasma alpha-tocopherol concentration of <12.0 µmol/L. The most important finding was that women with low alpha-tocopherol concentrations were almost twice more likely to miscarry than women with normal status. Women with low gamma-tocopherol status were also significantly more likely to miscarry than those with higher concentrations.

Women with low gamma-tocopherol status were also significantly more likely to miscarry than those with higher concentrations.
The
cutoff of plasma alpha-tocopherol concentration 12.0 µmol/L was
proposed to define vitamin E deficiency in normal, healthy adults.
However, it should be noted that currently there is no clearly defined
consensus on the definition of vitamin E deficiency in pregnant women
because alpha-tocopherol concentrations increase with blood lipids over
the course of pregnancy.
While
these findings show an association between adequate alpha-tocopherol
status and reduced risk of miscarriage in human populations, future
studies exploring the potential beneficial effects of adequate vitamin E
status during pregnancy are warranted.

Taking your vitamin D3 supplement with a meal containing fat increases absorption
Greetings Everyone
I personally don't endorse eating beef liver as I see the cow as mother and the bull as father according to the Vedic version but the point here is that some kind of fat be it yoghurt, avocado, nuts - is needed to better utilize Vitamin D3. Now that I have spoken my peace please read this important information courtesy of Usana Health Sciences.(They make the same point in the end of the article). - Ekayani
Taking your vitamin D3 supplement with a meal containing fat increases absorption
Vitamin D supplements may help bridge the gap. Because vitamin D is fat soluble, it seems logical that vitamin D supplements should be taken with a meal containing some fat. However vitamin D absorption differences based on dietary composition has been poorly understood.
A new study published in the Journal of the Academy of Nutrition and Dietetics sought to test the hypothesis that absorption of vitamin D3 improves when taken with a meal containing fat compared to a fat-free meal. In this study researchers recruited fifty healthy older men and women to complete this one day study and randomly assigned them to one of three meal groups: the first group consumed a fat-free meal; and the second and third groups consumed a meal with 30% of calories from fat but each provided a different ratio of MUFA’s (monounsaturated fatty acids) to PUFA’s (polyunsaturated fatty acids). After completing a 12-hour fast, all subjects took a single 50,000 IU vitamin D3 supplement with their test breakfast. Plasma vitamin D3 levels were collected and measured by liquid chromatography–mass spectrometry before the meal and 10, 12, and 14 hours after consuming the meal and supplement.
The results showed that the maximum vitamin D3 plasma level (12-hour time-point) was 32% higher in subjects consuming the fat-containing meals compared with the fat-free meal. Absorption did not differ significantly at any time point between the high and low MUFA and PUFA groups.
This study provides a better understanding of the importance of some type of fat in a meal to optimize the absorption of vitamin D3 (cholecalciferol) from supplements; however the type of fat consumed is not significant for absorption.

Impact of iron deficiency on exercise performance in women of reproductive age
Impact of iron deficiency on exercise performance in women of reproductive age
At a GlanceA new meta-analysis has shown that women athletes, of reproductive age, who take iron supplements, experience a significant improvement in exercise performance. Read more about this research below. |
Female athletes have a higher risk of this type of anemia due to dietary deficiencies, losses from blood and other bodily fluids, and reduced absorption due to exercised induced inflammation. Previous studies have suggested that low iron levels may impair exercise performance.
A study published in the Journal of Nutrition has found that women athletes of childbearing age with iron deficient anemia who supplement with iron experience a marked improved in exercise performance. Researchers performed a systematic review and analysis of the effect of iron supplementation and exercise performance of women in childbearing years utilizing randomized controlled trials that measured exercise outcomes to daily oral iron supplementation vs. control.
A study published in the Journal of Nutrition has found that women athletes of childbearing age with iron deficient anemia who supplement with iron experience a marked improved in exercise performance. Researchers performed a systematic review and analysis of the effect of iron supplementation and exercise performance of women in childbearing years utilizing randomized controlled trials that measured exercise outcomes to daily oral iron supplementation vs. control.
Iron supplementation improved women's exercise performance, in terms of both the highest level they could achieve at 100% exertion (maximal capacity) and their exercise efficiency at a submaximal exertion. Anemic and iron deficient women who received iron were better able to perform a given exercise using a lower heart rate and at a higher efficiency than women who were not taking an iron supplement.
This study helps establish evidence that iron deficiency impairs exercise performance in women and may help better establish the beneficial effects of iron supplementation on exercise performance in women, and the general health and well-being of women in the general population. However, additional studies/ evidence may be required to further clarify the effects of iron on other exercise variables, and for other functional outcomes, such as work performance, productivity, and potential adverse effects.
