#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.
The paper by Dr. John Sievenpiper a physician and researcher in the Clinical Nutrition and Risk Factor Modification Centre of St michael's Hospital was published today in the journal BMJ Open.*
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.
The U s. Food and Drug Administration has granted tree nuts a qualified health claim for cardiovascular disease risk reduction.
and DASH (Dietary Approaches to Stop Hypertension) diets for cardiovascular disease prevention and management based on their ability to reduce bad cholesterol.*

#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
because it's the only treatment for their condition said Karla Shelnutt a UF assistant professor in family youth and community sciences.
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.
They also filled out a questionnaire said Shelnutt a faculty member with UF's Institute of food and agricultural sciences. 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.
whom will live in areas where access to food is extremely scarce--by the year 2050.
The question lies in how to grow enough food to feed the world's population
and food availability challenges said Judith Carney a professor of geography at the Institute of the Environment and Sustainability at the University of California Los angeles and author of Black Rice.
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.
and Asians independently selected for many of the same genetic traits in the two species such as higher nutrition
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.
The beneficial health effects of dietary antioxidants have prompted the idea of developing commercial antioxidant-rich beverages.
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.
The bioactive composition (flavonoids and Vitamin c) of mango drink containing a mas cotek aqueous extract exhibited higher total phenolic content and total flavonoid compound compared to mango drink that did not incorporate mas cotek.
What's more when incorporated into mango drink the mas cotek aqueous extract did not affect the organoleptic properties of the drink.
Therefore our study suggests that the Golden-C --which consists of 20%mango pulp and 50%mas cotek--has the potential to be developed as a new health drink.

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.
From Foods to Nutrient Interactions on Bone and Skeletal muscle Health is now available in the Journal of the American College of Nutrition the Official Publication of the American College of Nutrition and a publication from Routledge.
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
and proteins and in many countries are fortified with Vitamin d. 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

#Climate change and air pollution will combine to curb food suppliesmany studies have shown the potential for global climate change to cut food supplies.
A new study involving researchers at MIT shows that these interactions can be quite significant suggesting that policymakers need to take both warming and air pollution into account in addressing food security.
The study looked in detail at global production of four leading food crops--rice wheat corn
and soy--that account for more than half the calories humans consume worldwide. It predicts that effects will vary considerably from region to region
The world is expected to need about 50 percent more food by 2050 the authors say due to population growth and changing dietary trends in the developing world.
For example while global food production was projected to fall by 15 percent under one scenario larger emissions decreases projected in an alternate scenario reduce that drop to 9 percent.
or conventional air pollutants such as wind and solar energy would be doubly beneficial to global food security as they do not contribute to either climate change

whether climate change will threaten food supply as if it's a simple yes or no answer Lobell said.
This would have a major impact on food supply. Yields would continue to increase but the slowdown would effectively cut the projected rate of increase by about half at the same time that demand is projected to grow sharply.
However global demand for crops is expected also to rise rapidly during the next two decades because of population growth greater per-capita food consumption and increasing use of biofuels.
But climate change has increased the odds to the point that organizations concerned with food security or global stability need to be aware of this risk.

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.
The study which appears online in Food Policy suggests that farmers market vouchers can be useful tools in improving access to healthy food.
In terms of healthy food options farmers market incentives may be able to bring a low-income person onto the same playing field as those with greater means said Carolyn Dimitri an associate professor of food studies at NYU
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.
Farmers markets may help fill in gaps in communities commonly referred to as food deserts which lack access to fresh healthy food.
One in four farmers markets in the U s. accepts Supplemental Nutrition Assistance program (SNAP) benefits formerly known as food stamps.
In recent years several local governments and nonprofit organizations have augmented federal food assistance by offering vouchers to use at farmers markets.
The vouchers increase the value of food assistance when used to buy fruits and vegetables at markets.
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.
To assess the effect of farmers market incentives on those receiving food assistance Dimitri and her colleagues enrolled 281 economically disadvantaged women in their study recruiting participants at five farmers markets in New york San diego and Boston.
The women were all caring for young children and received federal food assistance through SNAP or Women Infants and Children (WIC.
The researchers collected demographic information and surveyed the participants throughout the 12-16 week study to learn about their food shopping habits and fresh vegetable consumption.
Each time participants shopped at the farmers market they received up to $10 in vouchers to be used toward purchasing fruits and vegetables.
The women matched the amount of the farmers market vouchers with cash or federal food benefits.
and lived in food deserts were the most likely to drop out of the study. For those who completed the study more than half reported consuming vegetables more frequently at the end of the study.
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.
Our food choices are very complex and issues with food security won't be solved with a single program Dimitri said.
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.
Additional research is needed to understand why produce consumption did not increase among nearly half of the participants
While farmers markets are good sources of healthy food the researchers noted that relying on them exclusively for food security is problematic as markets are usually open on limited days and closed in the winter.

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.
