#Eating resistant starch may help reduce red meat-related colorectal cancer riskconsumption of a type of starch that acts like fiber may help reduce colorectal cancer risk associated with a high red meat diet
Red meat and resistant starch have opposite effects on the colorectal cancer-promoting mirnas the mir-17-92 cluster said Karen J. Humphreys Phd a research associate at the Flinders Center
This finding supports consumption of resistant starch as a means of reducing the risk associated with a high red meat diet.
Total meat consumption in the USA European union and the developed world has continued to increase from the 1960s
Good examples of natural sources of resistant starch include bananas that are still slightly green cooked and cooled potatoes such as potato salad whole grains beans chickpeas and lentils.
After eating 300 g of lean red meat per day for four weeks study participants had a 30 percent increase in the levels of certain genetic molecules called mir-17-92
Consuming 40 g of butyrated resistant starch per day along with red meat for four weeks brought mir-17-92 levels down to baseline levels.
Participants either ate the red meat diet or the red meat plus butyrated resistant starch diet for four weeks and after a four-week washout period switched to the other diet for another four weeks.

#Eating tree nuts results in modest decreases in blood fats and sugars, survey findseating tree nuts appears to help reduce two of the five markers for metabolic syndrome a group of factors that raise
and blood sugars among people who added tree nuts to their diets compared to those who ate a control diet.
Tree nuts are such things as almonds Brazil nuts cashews chestnuts coconuts hazelnuts pecans macadamia nuts walnuts pine nuts and pistachios.
They do not include peanuts which are legumes. In the randomized control studies patients ate about 50 grams of nuts a day or about 1-1/2 servings.
He said that people in North america consume on average less than one serving a day so this is one way they can adapt their diets to take advantage of the metabolic benefits.
Fifty grams of nuts can be integrated easily into a diet as a snack or as a substitute for animal fats or refined carbohydrates Dr. Sievenpiper said.

#When it comes to gluten-free diets, unfounded beliefs aboundwhile necessary for some many people eat gluten-free diets
because they believe they'll gain certain health benefits but these beliefs are supported not all by research a University of Florida nutrition expert says.
Those with celiac disease or about 1 percent of the U s. population must follow a gluten-free diet
But gluten-free diets can lack essential nutrients if a person does not eat a balanced diet
and/or take a multivitamin supplement. Unlike their conventional counterparts refined gluten-free foods for the most part are enriched not
or fortified with essential vitamins and minerals. If I'm a college student and I want to lose weight and
I read on the Internet that a gluten-free diet is the way to go
I may start avoiding products that contain essential nutrients such as those found in cereal grains fortified with folic acid Shelnutt said.
The problem is you have a lot of healthy women who choose a gluten-free diet because they believe it is healthier for them
The $10. 5-billion gluten-free food and beverage industry has grown 44 percent from 2011-13 as the rate of celiac disease diagnoses increases along with awareness of gluten-free foods
if gluten-free labeling has any impact on how consumers perceive the foods'taste and nutrition.
In a one-day experiment on the UF campus in Gainesville in February 97 people ate cookies and chips all gluten-free.
Half were labeled gluten-free; the other half labeled conventional. Participants then rated each food on a nine-point scale for how much they liked the flavor and texture.
About a third of participants said they believed gluten-free foods to be healthier than those labeled conventional a figure she thought would be much lower.
While avoiding gluten-containing foods can reduce carbohydrate intake thus helping some lose weight many health experts say a gluten-free diet is no healthier than a conventional diet except for those with celiac disease.
Although such a small sample cannot be generalized to the public Shelnutt said the experiment gives researchers insight into how the public views gluten-free foods.
For example 57 percent of participants believed gluten-free diets can be used to alleviate medical conditions
and 32 percent said doctors prescribe them for weight loss. Thirty-one percent believed gluten-free diets improve overall health 35 percent believed them to improve digestive health
and 32 percent felt that eating them would improve their diet. Gluten a protein is found in grains such as wheat barley rye and triticale a cross between wheat and rye.
A gluten-free diet is prescribed for those with celiac disease a condition that can damage the lining of the small intestine.
The experiment's results are published in the current edition of the Journal of Nutrition Education and Behavior.

The effort to sequence the African rice genome was led by Rod A. Wing director of the Arizona Genomics Institute at the UA and the Bud Antle Endowed Chair in the School of Plant sciences in the UA College of Agriculture
Rice feeds half the world making it the most important food crop Wing said. Rice will play a key role in helping to solve what we call the 9 billion-people question.
We're merging disciplines to solve the 9 billion-people question Wing said. Although it is cultivated currently in only a handful of locations around the world African rice is hardier
and more resistant to environmental stress in West african environments than Asian varieties Wing said. African rice already has been crossed with Asian rice to produce new varieties under a group known as NERICA which stands for New Rice for Africa.
or through genetic modification techniques noted Wing who is also a member of the UA's BIO5 Institute and holds the Axa Endowed Chair of Genome Biology and Evolutionary Genomics at the International Rice Research
Wing's research group specializes in developing what geneticists call physical maps a tool that enables scientists to understand the structure of the genome.
Yeisoo Yu a research associate professor in Wing's research group at the Arizona Genomics Institute led the sequencing effort.
what is known about the genetic structure of wild varieties Wing and his team found that it's most similar to a population of wild rice species found in one location along the Niger river in Mali.
Our data supports the hypothesis that the domestication of African rice was centric in this region of Africa Wing said.
From 1998 to 2005 Wing led the U s. effort to help sequence the genome of Asian rice which is the only other domesticated rice species. Those results were published in the journal Nature in 2005
Wing's research group is now focusing on sequencing and analyzing the genomes of the wild relatives of African and Asian rice.
and plant pathogens Wing explained. One example he said would be adding disease resistance genes from all of the wild rice varieties to a species of cultivated rice creating a new super-crop that is resistant to diseases and pests.
Wing is also working with Quifa Zhang from Huazhong Agricultural University in Wuhan China to create a set of super-crop science
In November Wing and his collaborators will celebrate the 10th anniversary of the completion of the Asian rice genome
A new mango drink enriched with antioxidants from mas cotekresearchers at the Universiti Teknologi MARA have enhanced the antioxidants present in mango fruit drink by adding the extracts of naturally occuring traditional herbs in Malaysia.
Malaysia has been blessed with a variety of fruits and herbs. Our daily diet includes the consumption of raw vegetables and herbs.
Scientific studies have been carried out to evaluate the beneficial effects of Malaysian herbs. A number of studies support the intake of local herbs to prevent diseases mainly caused by oxidative stress.
These studies have enabled some of our herbs to be turned into products either in tablet form
or mixed into drinks to simplify and assist the pharmacological effects of the herbs. Known to be rich in Vitamin c the mango is regarded as one of the most popular fruits from the tropics.
Numerous high quality mango clones are available in Malaysia. Our interest has been at incorporating an extract from local Malaysian herbs into the mango drink to create a new way of enjoying the goodness of mango.
The antioxidant properties of herbs have been proven to deliver beneficial effects and phenolic compounds such as flavonoids have been observed to provide antioxidant effects.
Thus herbs known to possess high antioxidant properties were selected for use in this study. However some herbs are not suitable for incorporation into mango drink due to the pungent taste and colour of the herb extract
which could interrupt the organoleptic properties of the mango drink. The objective of the present work was to produce a new mango drink enriched with the antioxidants of the mas cotek (Ficus deltoidea) herb.
This traditional herb is a plant from the Family moraceae that has been used traditionally for its medicinal properties.
Mas cotek is used for example to treat pneumonia diabetes hypertension diarrhoea and gout. We found that dried Ficus deltoidea leaves extracted with water at 50 degree celsius for 20 hours yielded an aqueous extract with the highest content of flavonoids and total phenolics.
A total of 25 flavonoid compounds consisting of 9 flavonols and 16 flavones were identified tentatively from dried leaves of mas cotek using high performance liquid chromatography (HPLC) coupled to a photodiode array and electrospray ionization mass spectrometry.
Our results suggest that mas cotek could be a suitable herb for adding to mango drink.
Moreover mas cotek has positive effects on glucose and lipid levels and has been found safe for use in humans.
and skeletal muscle healthunderstanding that diets are built often around food groups rather than specific nutrients researchers from Switzerland France
and North america decided to examine interactions between four nutrients found in dairy products and their role in preserving bone and skeletal muscle.
Calcium (Ca) inorganic phosphate (Pi) Vitamin d and protein are nutrients that impact bone and skeletal muscle integrity.
Deficiency in the supply of these nutrients increases with aging. Dairy foods are rich in Ca Pi
Dairy foods are important sources of these nutrients and go a long way to meeting the recommendations which increase with aging.
This review emphasizes the interactions between these 4 nutrients which along with physical activity act through cellular and physiological pathways favoring the maintenance of both bone and skeletal muscle structure and function.
Combining the four above-mentioned nutrients with physical activity decreases the likelihood of bone and muscle degeneration-related injury in older adults.
Dairy products are a convenient way to work them into a diet as they contain Ca Pi

and vegetables at farmers markets increase the amount of produce in the diets of some families on food assistance according to research led by NYU's Steinhardt School of Culture Education and Human Development.
Economically disadvantaged families tend to consume diets low in fruits and vegetables partially due to poor access to healthy food and their inability to pay for it.
One in four farmers markets in the U s. accepts Supplemental Nutrition Assistance program (SNAP) benefits formerly known as food stamps.
While most food assistance programs fail to address nutritional quality--for instance SNAP benefits can be used to buy ice cream
and soda--farmers market incentives can only be used on fresh produce increasing their potential to improve consumers'diets.
Participants with low levels of education and those who consumed little fresh produce at the beginning of the study were the most likely to increase the amount of produce in their diets.
Even though not all participants increased their consumption of produce our study suggests that nutrition incentives are a promising option that can help economically disadvantaged families eat healthier diets.

Occasionally underpasses and culverts also may be effective conduits for rabbit travel. The researchers hope that an improved understanding of how the cottontail moves through the landscape will assist wildlife and land managers in species recovery efforts.
Researchers identified the genetic pattern of individual rabbits and used information about genetic relatedness to make estimates of gene flow.

and snacks inside fall short of federal guidelines. Those are the findings of a study conducted by researchers at the Friedman School of Nutrition Science and Policy at Tufts University and in the Department of public health and Community Medicine at Tufts University School of medicine.
Led by senior author Jeanne Goldberg Ph d. R. D. a professor at the Friedman School the study is among the first to examine what children bring to school for lunch and snack.
The researchers used digital photography to document the lunches and snacks of more than 600 Massachusetts third and fourth graders in 12 schools in six public school districts.

#Real price of steak: Comparing environmental costs of livestock-based foodswe are told that eating beef is bad for the environment
but do we know its real cost? Are the other animal or animal-derived foods better or worse?
The team looked at the five main sources of protein in the American diet: dairy beef poultry pork and eggs.
Their idea was to calculate the environmental inputs-the costs-per nutritional unit: a calorie or gram of protein.
Cattle in feedlots on the other hand eat mostly corn which requires less land but much more irrigation and nitrogen fertilizer.
When the numbers were in including those for the environmental costs of different kinds of feed (pasture roughage such as hay
The calculations showed that the biggest culprit by far is beef. That was no surprise say Milo and Shepon.
In total eating beef is more costly to the environment by an order of magnitude-about ten times on average-than other animal-derived foods including pork and poultry.
and consume 6 times as much nitrogen as eggs or poultry. Poultry pork eggs and dairy all came out fairly similar.
That was also surprising because dairy production is thought often to be relatively environmentally benign. But the research shows that the price of irrigating
In addition to helping individuals make better choices about their diet it should hopefully help inform agricultural policy.
and refined to be applied for example to understanding the relative cost of plant-based diets or those of other nations.
Meat turns up the heat as livestock emit greenhouse gaseseating meat contributes to climate change due to greenhouse gasses emitted by livestock.
This is expected to increase further going forward as demand for meat dairy products and eggs is predicted by some scientists to double by 2050.
By contrast developed countries reached maximum livestock emissions in the 1970s and have been in decline since that time.
but this improvement is not keeping up with the increasing demand for meat said Caro.
Breaking it down by animal beef and dairy cattle comprised 74 percent of livestock-related greenhouse gas emissions 54 percent coming from beef cattle and 17 percent from dairy cattle.
Sheep comprised 9 percent buffalo 7 percent pigs 5 percent and goats 4 percent. That tasty hamburger is the real culprit Caldeira said.
It might be better for the environment if we all became vegetarians but a lot of improvement could come from eating pork or chicken instead of beef.

and kept in the lab on a diet of rabbit chow. In the first experiment the scientists studied the relative abundances of gut-microbe genes in two groups of the creosote-eating Mojave woodrats.
One group was fed rabbit chow containing 1 percent of creosote resin for two days followed by rabbit chow with 2 percent of creosote resin for three days.
The scientists found that a woodrat's diet determines the composition of its gut microbes.
One group was placed on a diet of rabbit chow and creosote resin. With their gut microbes killed by the antibiotic they were unable to feed on creosote
and showed that acquiring new microbes indeed helped woodrats adopt new diets. Woodrats naturally eat their own and other woodrats'feces.
So in the experiment juniper-eating Great Basin woodrats were fed rabbit chow mixed with feces either from other juniper eaters or from creosote-eating Mojave woodrats.
--and thus gut microbes--from creosote eaters juniper eaters persisted for 11 days on the creosote diet without losing much weight.
when woodrats didn't get transplants of creosote-detoxifying microbes their urine was more acidic suggesting their livers expended a lot of energy to degrade creosote toxins.
But in juniper eaters that consumed the feces of creosote eaters their newly acquired gut microbes likely detoxified most of the creosote taking the burden off of liver enzymes.

#Eating lean beef daily can help lower blood pressure, study suggestscontrary to conventional wisdom a growing body of evidence shows that eating lean beef can reduce risk factors for heart disease according to recent research by nutritional scientists.
This research adds to the significant evidence including work previously done in our lab that supports lean beef's role in a heart-healthy diet said Penny M. Kris-Etherton Distinguished Professor of Nutrition Penn State.
This study shows that nutrient-rich lean beef can be included as part of a heart-healthy diet that reduces blood pressure
which can help lower the risk for cardiovascular disease. The DASH eating plan--Dietary Approaches to Stop Hypertension--is recommended currently by the American Heart Association to lower blood pressure
and reduce risk of heart disease. People following the DASH diet are encouraged to eat fruits vegetables low-fat dairy and protein predominantly from plant sources.
The Beef Checkoff Program and the National institutes of health-supported Penn State General Clinical Research center funded this research.
Lean beef can be enjoyed as the predominant protein source in a DASH-like diet along with fruits vegetables and low-fat dairy to effectively help lower blood pressure in healthy individuals the researchers report in the Journal of Human Hypertension.
This DASH-like diet is called also the BOLD+diet--Beef in an Optimal Lean Diet plus additional protein.
Kris-Etherton and colleagues tested four diets to find the effects on vascular health. The diets tested included the Healthy American Diet
--which served as the control--the BOLD+diet the BOLD diet and the DASH diet.
The control diet consisted of 0. 7 ounces of lean beef per day while the DASH diet included 1. 0 ounce.
The BOLD diet had 4. 0 ounces and the BOLD+diet included 5. 4 ounces of lean beef.
The researchers tested the four different diets with 36 participants between the ages of 30 and 65.
All participants followed each diet at different times throughout the study period. Subjects were assigned randomly an order to follow each of the four diet plans for five weeks each with a break of one week in between each new plan.
Blood pressure was taken at the beginning and end of each diet period. The BOLD+diet was more effective at reducing blood pressure
when compared to the other diets tested. This evidence suggests that it is the total protein intake--not the type of protein--that is instrumental in reducing blood pressure as part of a DASH-like dietary pattern the researchers stated.
