Ancient Civilization Made Rapid Switch Bones unearthed from an ancient mound in Turkey suggest that humans there shifted their diet from hunting to herding over just a few centuries findings that shed light on the dawn of agriculture scientists say.
Stone-age Burials in Africa Layers of history The research team led by archaeologist Mihriban Ãbaå aran at Istanbul University discovered the people of the oldest levels of the site originally ate a broad diet of meat from creatures
This included diverse small animals such as hares fish turtles hedgehogs and partridges as well as larger prey such as deer boars horse goats sheep extinct wild
However by 8200 B c. the meat in the diet shifted overwhelmingly to sheep and goats.
Young male sheep and goats were killed selectively probably for their meat leaving females and some males to breed more livestock.
and the best and largest kinds of game will get targeted first Stiner told Live Science.

Old world monkeys have rump pads but New world monkeys do not. Also Old world monkeys'nostrils are curved small and and set close together;
This means that they eat meat and plant-based foods. Most monkeys eat nuts fruits seeds and flowers.
Some monkeys also eat meat in the form of bird's eggs small lizards insects and spiders.
This is because the sugars in ripe fruit ferment. The fermentation causes bloating in the stomach that can kill them.

Instead kosher refers to foods that adhere to the dietary laws of Judaism also called kashrut as described in the Torah.
Not only can the meat of these forbidden animals not be eaten but the flesh organs eggs and milk are prohibited also.
Land mammals: In order to be kosher land animals must have cloven hooves and chew their cud.
This means that meat from cows is kosher while that of camels rabbits and pigs is not.
Sea animals: Kosher sea dwellers must be equipped with fins and scales. So while salmon and tuna are fit for consumption lobsters clams
Permitted birds include chicken geese ducks and turkeys. Even foods that are allowed must be prepared in a particular way to be considered kosher.
or added spices and instead relates to the slaughter and subsequent handling of the animal.
In other words utensils cannot be used to prepare kosher meats if they have interacted with dairy eggs or nonkosher food.
In fact Jewish people who follow kashrut avoid eating meats and dairy products together and some even wait a certain amount of time before consuming one after the other according to the Biblical Archaeological Society.
In addition to meats and other foods to be considered kosher wines and grape-based products must be made by a Jewish producer.

#Mother's Diet at Time of Conception May Alter Baby's DNA A woman's diet at the time of conception might cause lasting changes in the DNA of her children potentially influencing their development researchers say.
In a new study researchers analyzed the diets of women in rural parts of The gambia in western Africa who experience major changes in their diets over the course of each year as the area goes through rainy seasons and dry seasons.
Yearlong staples of the women's diet include rice a grain called millet peanuts and cassava.
which are very high in folate a nutrient that is especially important during pregnancy. The scientists investigated the concentration of nutrients in the blood of 84 pregnant women who conceived at the peak of the rainy season
and 83 women who conceived at the peak of the dry season. In addition they analyzed the DNA of six specific genes in the women's infants
Methylation generally depends on nutrients such as folate choline methionine and vitamins B2 and B6 the researchers said.
In the study methylation in the infants'genes was linked to various nutrient levels in the mother's blood.
For instance a 2003 study revealed a female mouse's diet can alter the color of her offspring's coat by permanently modifying DNA methylation.
It's also important to note that their diet wasn't the only thing that changed there was more physical activity due to farm labor during the rainy season
what nutrients are circulating within the women. In the new study a nearly identical epigenetic effect was found in both blood and hair-follicle DNA of the infants.
Our ultimate goal is to define an optimal diet for mothers-to-be that would prevent defects in the methylation process study author Andrew Prentice of the London School of Hygiene
Now our research is pointing towards the need for a cocktail of nutrients which could come from the diet or from supplements.
The scientists detailed their findings online today (April 29) in the journal Nature Communications. Follow us@Livescience Facebook & Google+.
Health Benefits, Risks & Nutrition Facts Rich creamy and flavorful avocados are a versatile fruit that add heft and health to many dishes.
While avocados have a high fat content they are packed also with nutrients and are a great way to add healthy fat to your diet.
Healthy fat sometimes called monounsaturated fat in the form of oleic acid accounts for about three-quarters of the calories in an avocado.
Their sugar levels are also comparatively low. Avocados contain many essential vitamins and minerals. They are a good source of vitamins K B9 B6 B5 C
One 1996 study found that patients with mild hypercholesterolemia who incorporated avocados into their diet for one week had a 22 percent decrease in bad cholesterol and triglycerides and an 11 percent increase in good cholesterol.
and the low carb and sugar levels in avocados help maintain blood sugar in comparison to other fruits.
They are also quite filling meaning that eating too many avocados may not leave you enough room to get other essential nutrients such as protein.
If you experience any of these symptoms after eating an avocado try cutting the fruit out of your diet to see

#Cancer-Fighting Diet: 6 Tips to Reduce Your Risk Following six diet guidelines can reduce your cancer risk researchers say.
The recommendations which appear in the June 30 issue of the Journal of the American College of Nutrition were spearheaded by the Physicians Committee for Responsible Medicine (PCRM) a Washington D c.-based nonprofit group known for its advocacy of plant-based diets
Perhaps not surprising for an organization that encourages plant-based diets the advice highlighted the benefits of fruits and vegetables and recommended limited consumption of meat.
avoid red meats and processed meats; and avoid grilled broiled or fried meats. 10 New Ways to Eat Well The overall recommendation is to favor plant-based foods said lead author Joseph Gonzales a registered dietician with the PCRM.
Plants are rich in protective compounds and help consumers avoid the cancer-causing substances found in animal products.
It's never a bad idea to cut back on red meat or alcohol as the PCRM recommends said Colleen Doyle a registered dietician and director for nutrition and physical activity for the American Cancer Society.
It is an incontrovertible fact that a plant-based diet lowers your risk of cancer
and if substituted for red meat can help reduce exposure to fats and other chemicals that promote cancer
5. Avoid red and processed meats to reduce the risk of cancers of the colon and rectum.
Large studies from the Harvard School of Public health revealed that regular consumption of red meat particularly processed meats such as sausages
and cold cuts will shorten your life. This news doesn't need to ruin your summer cookout plans.
Doyle said to exercise common sense and that the occasional hamburger or hotdog even grilled (uh-oh see the next recommendation) is fine.
The broader issue she said is reducing consumption to reduce risk given your risk profile
and family history. 6. Avoid grilled fried and broiled meats to reduce the risk of cancers of the colon rectum breast prostate kidney and pancreas.
when creatine and amino acids in skeletal muscle aka meat are cooked at high temperatures. Even the smoke from grilled meat can contaminate grilled vegetables
which otherwise don't have HCAS. Cancer risk reduction doesn't guarantee cancer avoidance. According to the World health organization up to 30 percent of all cancers might be caused by a poor diet.
The rest are attributed to smoking pollution and genetics which may affect you no matter what you eat.
#Where Do Cashews Come From? Though you might think of it as just another nut in the trail mix the cashew is a decidedly strange snack.
Sprouting like a tail from the bottom of an oddly-shaped fruit the cashew in its natural state is both very weird-looking and very poisonous.
While many of the cashews produced for commerce come from Africa and India the cashew tree (Anacardium occidentale) is native to tropical regions of Brazil.
The tree produces a long fleshy stalk called a cashew apple which resembles a small pear.
At the end of this stalk grows the kidney-shaped cashew nut that many know and love. Cashew nuts are protected from hungry passerby by a double shell containing a potent poison called anacardic acid.
This oily substance#closely related to urshiol the toxic compound found in poison ivy poison oak and poison sumac#acts as an irritant causing an allergic rash on the skin.
Its corrosive coating is the reason that cashew nuts are sold not in their shells like pistachios or peanuts.
Instead cashews are dried typically and roasted a process that rids the nut of toxic oils and leaves its shell brittle and easy to remove.
However cashews that have not been dried and roasted can be purchased in some stores and online. But as Deborah Enos a certified nutritionist and health coach explains in her column for Live Science people should use caution
when purchasing any cashews labeled as raw. Though these nuts are steamed most likely or otherwise processed Enos said that those with a severe allergy to urshiol
(i e. poison ivy) may not want to risk finding out whether these processes for removing anarcardic acid are entirely effective.
Despite its propensity to poison the cashew is lauded for its substantial store of nutrients. Along with Brazil nuts and almonds cashews have the highest magnesium content per serving of any tree nut.
And like most nuts cashews are also a good source of Vitamin e and cancer-fighting phytochemicals.
See also: Top 10 Cancer-Fighting Foods And in addition to the cashew's known nutritional benefits researchers have explored also the possibility of using the toxic oil found in the nut's shell as an antibiotic.
One study by researchers at University of California Berkeley found that anarcardic acid is effective at killing the bacteria that causes acne as well as that which causes tooth decay and the erosion of tooth enamel.
According to the researchers using cashew oil isn't an entirely new idea as the acid was used at one time in Brazil to treat leprosy.
Cashew nut oil as well as the leaves and bark of the cashew tree have also been used in traditional medicines in communities around the world to treat everything from toothaches to diabetes.

#The 9 Unhealthiest Restaurant Meals French toast served with butter syrup and bacon a platter of fried seafood and hush puppies and a cheesecake made with Reese s peanut butter cups
and fudge are among the meals singled out this year for their shockingly unhealthy nutrition content in a new report from a nonprofit watchdog group.
Nine meals from American chain restaurants were selected for the 2014 Xtreme Eating Awards a list released yearly by the Center for Science in the Public interest as a way to highlight meals that are very high in calories saturated
fat sodium and sugar. Nearly all the meals on this year's list have at least 2000 calories and a few top 3000 calories.
You could take half home and still overeat the CSPI says. Three of the meals on the list are from the Cheesecake Factory including the restaurant's Brulã ed French toast
which consists of custard-soaked bread powdered sugar maple-butter syrup and bacon and contains more than 2700 calories CSPI says.
The meal also has 93 grams of saturated fat which is nearly five days'worth CSPI says.

To help people avoid overeating while dining out CSPI recommends the following when possible: Order from the lower-calorie menu
if one is offered; take home half of a regular meal; order alternative sides such as steamed broccoli in place of fries;
order a burger with lettuce in place of the bun; order a thin-crust pizza instead of a deep-dish pizza;
for Mexican dishes order items à la carte instead of as a combo meal; and ask for no chips.

#A Centenary for the Last Passenger pigeon (Op-Ed) Steve Zack is coordinator of Bird Conservation for the Wildlife Conservation Society (WCS.
He contributed this article to Livescience's Expert Voices: Op-Ed & Insights. Monday is the centenary of the extinction of the passenger pigeon.
That timing is precise because we know that the very last bird (Martha after Martha Washington) died in the Cincinnati Zoo on September 1 1914.
The passenger pigeon was a bird of eastern North america that moved in search of mast. Mast is a botanical term for the hard nut fruits produced by trees like beeches and acorns.
In the eastern deciduous forests of what is now the United states the search for mast was extensive
and frequently synchronized between different species regionally. The immense flocks of passenger pigeons were most abundant in these forests.
Images of Rare Passenger pigeon Museum Specimens That seems the essence of the passenger pigeon's ecology (consuming abundant mast)
and its behavior (the massive flights of these birds across the country until such mast was found).
The abundance of the species was proportional to the abundance of its mast. Colonial Americans felled the forests for their wood and to make room for agriculture.
Once abundant mast began to disappear the pigeons also lost the capacity to breed twice in a season across different masting locales.
The market hunting of mere millions of birds paled in comparison to the loss of billions that once darkened the skies in search of mast.
and mast disruption that meant the end decades before Martha's lonely demise. Forests remained but not the copious mast.

Health Benefits, Risks & Nutrition Facts Sweet juicy oranges make a delicious and healthy snack or addition to a meal.
Orange juice is packed also with nutrients but does not contain the fiber of a whole orange.
Oranges are a low-fat nutrient-rich food with a low glycemic index which make it an ideal food to consume to protect against obesity
Foods with a high glycemic index (such as white bread) cause glucose levels to spike quickly after they are eaten
This nutrient contains carotenoid compounds like lutein beta-carotene and zeaxanthin which can help prevent age-related macular degeneration an incurable condition that blurs central vision.
Orange peels are not poisonous and as many cooks know orange zest can pack a big flavor punch.
If you do eat the peel you'll get a good amount of nutrients. Orange peel actually has more fiber then the fruit inside contains Flores said.
One way to get some of the nutrients is by eating the inner part of the peel and leaving the tough outer part.

and salsa was just a dance. But as America braces for an onslaught of Super bowl snacks these words have a whole new relevance.
When you think about pizza and spaghetti it's the same thing Jim Kabbani CEO of the Tortilla Industry Association told the AP speaking of another ethnic food that's been embraced wholeheartedly by Americans.
People consider them American not ethnic. The avocado Persea americana is a native of Central america but over the years its popularity has spread
and are often gluten-free they may be fried in oils that are saturated high in and/or trans fats and many brands of chips are high in sodium.
Some health experts recommend baking your own tortilla chips from 100 percent corn tortillas and adding only as much salt as you prefer.
It bears mentioning that many potato chips are flavored now with Hispanic-style ingredients such as jalapeno peppers or nacho cheese.
what's now called dip though people had been dunking bread and crackers into soups and sauces for centuries.
A 1947 edition of the Fannie Farmer cookbook included a recipe for mayonnaise preparations flavored with mustard
or Worcestershire sauce that were made for dipping asparagus tips or cauliflower florets. By the 1950s the Lipton Company was searching for new ways to market its line of dried instant soups.
By mixing the soups with sour cream the company launched a whole new era in eating creating a mix intended for no other purpose than to dip celery carrots or chips.
According to Fox news 32 percent of Americans plan to scoop up some kind of creamy dip during the Super bowl.
Salsa: Tomato-based salsa the most popular type of salsa sold in the United states overtook ketchup in sales in 1991 according to The New york times. Food historians cheered the dethroning of ketchup as the condiment king
since salsa's spicy blend of tomatoes peppers onion garlic and other flavors heralded the dawn of more sophisticated cosmopolitan taste buds.
Sophisticated or not market research indicates that salsa sales now beat ketchup sales two-to-one the AP reports
and health concerns are part of the reason: When it comes to health the Mexican cuisines cater better to that with salsas
and vegetables Alexandra Aguirre Rodriguez an assistant professor of marketing at Florida International University told the AP. Follow Marc Lallanilla on Twitter and Google+.
