We evolved to crave sugar starch and fat. We evolved to be physically active but we also evolved to be said lazy Lieberman who discussed the consequences of living with a Stone age body in a Space age world.
Humans crave high-energy foods like fats and carbohydrates because such food was hard to come by in the Stone age
but can now be consumed in great abundance to the detriment of the body. Meanwhile humans typically opt out of energy-intensive habits such as walking to destinations
That's how hunter-gatherers got their dinner every day. Walking keeps humans healthy by stimulating blood flow
and manage to get by fine with glasses. 5. Sugar or veggies? Some estimates suggest the Paleolithic diet consisted of 4 to 8 lbs of sugar per year.
Today the average American consumes more than 100 lbs (45 kilograms) of sugar per year Lieberman said.
This drastic increase had been implicated partially in the rise of heart disease and diabetes as leading causes of death in the country over the past several decades.
Excessive Added Sugar Clogs Americans'Diets But cavemen weren't watching their calories; they just didn't have access to the huge quantities of sugar available today.
Modern technology allows humans to extract sugar from a wide range of sources including sugar cane maple trees beehives
and corn stalks and ship that sugar around the world in huge quantities and at unprecedented speeds.
If given the chance to gorge on candy bars Paleolithic children probably would have wanted to just as much as modern children do said Lieberman.
But they just didn't have that option. That kid had no option but to eat healthy food
and to exercise because that is what she did said every day Lieberman. Now we have to teach our children to make choices for

#6 Surprising Environmentalists There was a time not very long ago when it was safe to be a politician who supported environmental causes even among conservative Republicans.
In the spirit of celebrating Earth Day here are six political leaders who despite their conservative bona fides were among the most influential supporters of the environment. 1. Margaret Thatcher Trained as a chemist at Oxford university the late British Prime minister Thatcher may have understood the scientific underpinnings of climate change and other environmental issues better than most other

#6 Ways to Feed 11 Billion People Feeding the world's growing population will not be an easy task.
The planet can definitely produce enough food for 11 billion people experts say but whether humans can do it sustainably
and whether consumers will ultimately be able to afford that food are separate matters. Humans can't rely on a single solution to feed a population of this size experts say.
of which will move humans a little bit closer toward closing the gap between the amount of food they have
and the amount of food they need. Here are six possible strategies to help feed 11 billion people:
Eat less meat As society tries to feed the growing population it will have to pay close attention to the use of the Earth's resources
or risk making the situation worse. Beef in particular is not a very sustainable food to eat said Jamais Cascio a distinguished fellow at the Institute for the Future a think tank in Palo alto Calif. According to Cascio's calculation the greenhouse gas emissions generated by the production of cheeseburgers in the United states
each year is about equal to the greenhouse gas emissions from 6. 5 million to 19.6 million SUVS over a year.
which may involve eating more vegetables which take much less energy to produce and less meat Cascio said.
What 11 Billion People Mean for Food security Eat fake meat? Another perhaps more outlandish solution may be to eat meat that isn't from an animal at all.
Scientists have been working to develop cultured meat or synthetic meat grown in a lab. Earlier this year researchers in The netherlands showcased their lab-grown burger
and allowed a taste test. However right now the cost is exorbitant (a single burger costs $325000)
and it does not taste exactly like meat (tastetesters said the burger was dry). But with future research the price is likely to come down
and the product's taste could improve Cascio said. However some have been skeptical that lab-grown meat would be truly more sustainable than meat from cows.
Cultured meat still requires nutrients and currently researchers feed lab meat in part with blood from cow fetuses according to a 2012 Discover Magazine post by Christina Agapakis a synthetic biologist at UCLA. Researchers have proposed that they could one day use algae to feed cultured meat
but this has not been proven. Throw less food away One big inefficiency in today's food systems is how much food is wasted:
One out of every four calories that's produced for human consumption today is consumed not ultimately
because it is lost or wasted according to the World Resource Institute a nonprofit organization that aims to protect the Earth for current and future generations.
 Some 56 percent of global food loss and waste occurs in the developed world.
And the average American household loses $1600 a year on wasted food WRI says. At home Americans can reduce the amount of food they throw away by eating leftovers
or not preparing more food than they'll need for a given meal said Craig Hanson director of the People & Ecosystems Program at WRI.
Aquaponics One up-and-coming idea for sustainable food production is based actually on an ancient concept called aquaponics a system that combines fish farming with plant farming in water.
The fish fertilize the plants and the plants clean the water for the fish according to Johns Hopkins Bloomberg School of Public health
which has its own aquaponics project. You can eat the fish you can eat the plants
Vertical farming Given the scarcity of new agricultural land to grow food some have proposed taking farming into the sky:
Dickson Despommier an ecologist and professor at Columbia University said that food grown in skyscrapers would have many advantages.
Food produced in vertical farms would not be in danger of being lost due to extreme weather events
Efforts should be made to improve crop production in those areas using the foods that are grown already
Processed foods contribute more than 70 percent of the total sodium found in the American diet said Dr. Linda Van horn a research nutritionist at Northwestern University in Chicago
The goal of the challenge is to help Americans reduce sodium intake over the course of three weeks by changing the foods they choose.
As you cut back on the amount of sodium you consume foods taste saltier over time.
A low-salt diet is something within your control. Here are six easy ways to jumpstart a lower-sodium life:
Read labels We want people to read food labels and track their sodium consumption to get an idea of how much they are eating which
and a professor of nutrition and medicine at the University of Vermont said in a statement about the Sodium Swap Challenge.
Once people know just how much salt is in the foods they eat it'll be easier to figure out how to cut back.
Replace sodium-rich foods with produce Fruits and vegetables fill you up without adding sodium to the diet.
And the potassium that's found in fruits and veggies can keep blood pressure at healthy levels too.
Break bread wisely Bread and sodium may seem like an unlikely duo but some breads can contain a hefty amount of salt.
Spend five minutes comparing breads at the grocery store to find options that are lower in sodium advised Van horn. Another possibility:
Trade loaf-style bread for pita bread or tortillas which tend to contain less salt Van horn added.
Cut back on cured meats They're packed with sodium. Either avoid them altogether or at least look for forms of the product that have the least amount of sodium Van horn said.
Rethink pizza The problem with takeout pizza: Between the dough sauce cheese and toppings such as olives
and pepperoni sodium can add up. To keep the sodium content down choose lower-in-sodium sauces and cheese.
Pass on the pepperoni and choose healthier toppings such as mushrooms or broccoli. Speak up in restaurants Eating out means people don't know how the food they order will be prepared.
But Van horn said this concern can be addressed. Many chefs are accustomed much more these days to helping consumers stick with their recommended diets she explained.
In a fine-dining establishment ask for a reduced-sodium option. Minimizing sodium is more of a challenge in fast food restaurants
however when condiments and french fries are prepared typically in bulk. In these instances Van Horn recommended choosing a salad or plain hamburger without the bun or condiments.
Finding lower-sodium foods in fast food venues can be done but you have to be very selective Van horn said.
Pass it on: Easy dietary tweaks can help lower sodium intake. This story was provided by Myhealthnewsdaily a sister site to Livescience.

#7'Bad'Foods You Should Be Eating (Op-Ed) Katherine Tallmadge M. A r. D. is registered a dietitian;
author of Diet Simple: 195 Mental Tricks Substitutions Habits & Inspirations (Lifeline Press 2011; and a frequent national commentator on nutrition topics.
This article was adapted from one that first appeared in the Washington post. Tallmadge contributed this article to Livescience's Expert Voices:
Op-Ed & Insights. Are you shying away from bad foods that are actually good for you?
With all the hoopla about healthful eating it's hard to separate fact from fiction. As a nutrition consultant I've come to realize there is no shortage of surprises and superstitions in the world of nutrition.
As a follow-up to 5 So-called Health foods You Should Avoid I thought it would be fun to give you reasons to enjoy some of your favorite bad foods that could actually be good for you.
Gluten and wheat They are demonized the most ingredients beyond high-fructose corn syrup and hydrogenated oil said Melissa Abbott culinary director at the Hartman Group a company specializing in consumer research.
Yet decades of studies have found that gluten-containing foods such as whole wheat rye and barley are vital for good health and associated with a reduced risk of diabetes heart disease cancer and excess weight.
Wheat is a good source of fiber vitamins and minerals said Joanne Slavin nutrition professor at the University of Minnesota.
She added that the confusion about gluten a protein has caused some people to avoid eating wheat and other grains.
Only about 1 percent of the population those with celiac disease or a wheat allergy cannot tolerate gluten
and must eradicate it from their diet to ease abdominal pain and other symptoms including the ability to fully absorb vitamins.
One reason wheat-free or gluten-free diets are popular is that people who don't eat wheat often end up bypassing excess calories in sweets and snack foods.
Then they start feeling better lose weight and mistakenly attribute their success to gluten or wheat avoidance.

Most People Shouldn't (Op-Ed). Eggs Eggs also don't deserve their bad reputation. In recent decades their high cholesterol content has been thought to play a role in increasing LDL (bad) cholesterol and heart-disease risk.
But cholesterol in food is a minor factor contributing to high blood cholesterol for most people
and studies have not confirmed a correlation between eggs and increased heart-disease risk. The major determinant of LDL cholesterol is saturated fat
and while eggs are high in cholesterol (184 milligrams in the yolk) they're relatively low in saturated fat about 1. 6 grams in the yolk.
Interestingly some of the biggest egg eaters in the world the Japanese have low cholesterol
and heart-disease rates in part because they eat a diet low in saturated fat. In contrast Americans eat eggs alongside sausage bacon
and buttered toast. The amount that one egg a day raises cholesterol in the blood is extremely small says Walter Willett professor of epidemiology and nutrition at Harvard's School of Public health.
Elevations in LDL (bad) cholesterol of this small magnitude could easily be countered by other healthy aspects of eggs.
Potatoes Potatoes have been blamed for increasing blood glucose levels insulin resistance excess weight and Type 2 diabetes.
A recent Harvard study that followed large populations and their disease rates linked potato consumption with being overweight blaming it on the blood glucose rise.
But many foods including whole-wheat bread and whole-grain cereals cause similar spikes in blood glucose and are correlated with superior health and lower body weights.
How could the higher body weight in the Harvard study be explained? The study lumped all potato products together including potato chips and french fries
which are of course very fattening versions of potatoes usually eaten in large portions alongside hamburgers hot dogs and sodas.
It's an easy food to attack but the meal pattern may be said the culprit David Baer a research leader at the Agricultural research service of the Department of agriculture.
Other epidemiological studies have not verified a connection between potatoes and weight gain or any diseases and no clinical studies have shown a connection..
Potatoes are a great source of potassium Vitamin c and fiber that many cultures Scandinavians Russians Irish and Peruvians relied on as a nutritious staple for centuries.
And they were not fat. Fruits People often ask me if fruit is too high in sugar especially for diabetics.
This fear of fruit I believe is left over from the Atkins craze which discouraged eating some fruits on the grounds that they are high in carbohydrates.
Avoiding fruit could actually damage your health. Study after study over many decades has shown that eating fruit can reduce the risk of some cancers heart disease blood pressure
and diabetes. 10 New Ways to Eat Well Fruit is high in water and fiber
which help you feel full with fewer calories one reason why their consumption is correlated with lower body weight.
Even though they contain simple sugars most fruits have a relatively low glycemic index. That is when you eat fruit your blood sugar raises only moderately especially
when compared with refined sugar or flour products. Several health organizations including the U s. Department of health and human services and the U s. Department of agriculture (USDA)( via the U s. Dietary Guidelines) the National Cancer Institute and the American Heart Association recommend Americans eat at least five cups of fruits and vegetables a day because of their superior health
benefits. Soy Though popular for centuries in many Asian cuisines soy is seen sometimes as dangerous after studies found elevated rates of breast cancer among rats
when they were fed a concentrated soy derivative. But studies looking at whole soy foods in humans have not found a connection.
In fact the reverse may be true. Soy when consumed in childhood or adolescence may make breast tissue less vulnerable to cancer development later in life
and probably has no effect on breast-cancer risk when consumption begins in adulthood said Karen Collins registered dietitian and nutrition adviser with the American Institute for Cancer Research.
Actually Collins said the evidence is so strong that soy protects against heart disease that the FDA allowed a health claim for labels on soy food products. 12 Tips for Eating Healthy on a Budget Alcohol Alcohol is feared because of the potential for abuse
and alcoholism as well as complications such as liver disease which are all valid concerns. But decades'worth of research shows that moderate alcohol consumption can reduce deaths from most causes particularly heart disease
and that it raises HDL (good) cholesterol the USDA's David Baer said. Wine may have additional benefits
because its grapes are filled with nutrients called polyphenols which reduce blood clotting inflammation and oxidation. The key is to drink alcohol moderately and with meals.
What's moderation? One serving daily for women and two servings for men with a serving being 5 ounces of wine 12 ounces of beer or 1. 5 ounces of spirits.
Fried foods While it's true that frying food usually increases its caloric content that doesn't necessarily make it unhealthful.
As long as food is fried in healthful oil instead of butter shortening or trans fat and it's eaten in moderation it isn't less healthy.
In fact fat-soluble vitamins A d E and K; and heart-healthy cancer-preventive carotenoids such as beta-carotene (found in carrots
and sweet potatoes) lycopene (found in tomatoes) and lutein/zeaxanthin (found in deep-green leafy vegetables such as spinach
and kale) need fat in order to be absorbed by the body. The consumption of certain fats such as saturated fatty acids and trans fatty acids fats that are solid at room temperature is associated with an...
increased risk of cardiovascular disease. On the other hand the unsaturated fats monounsaturated fatty acids and polyunsaturated fatty acids e g. canola safflower and olive oils have significant metabolic benefits
and are health promoting said the 2010 U s. Dietary Guidelines Advisory Committee. The views expressed are those of the author

Sharks About 100 million sharks are killed each year to be made into shark fin soup a Chinese delicacy.
However China's taste for the dish may be fading: According to the American environmental group Wildaid consumption of the soup is down 50 to 70 percent in the last two years.
Nevertheless one-third of sharks and rays are threatened with extinction according to a 2009 study by the IUCN.
#7 Insects You'll Be Eating in the future As the human population continues to inch closer to 8 billion people feeding all those hungry mouths will become increasingly difficult.
As if to underscore that claim a group of students from Mcgill University in Montreal has won the 2013 Hult Prize for producing a protein-rich flour made from insects.
what they call Power Flour. We will be starting with grasshoppers team captain Mohammed Ashour told ABC News on Monday (Sept. 30.
Earlier this year the Food and agriculture organization of the united nations (FAO) released a report titled Edible Insects: Future Prospects for Food and Feed Security.
The document details the health and environmental benefits derived from a diet supplemented by insects a diet also known as entomophagy.
Gleaned from the FAO document and other sources here's a list of seven edible insects you may soon find on your dinner plate.
Eat This! 7 Perfect Survival Foods Mopane caterpillars Mopane caterpillars the larval stage of the emperor moth (Imbrasia belina) are common throughout the southern part of Africa.
Harvesting of mopane caterpillars is a multi-million dollar industry in the region where women
the dried form can last for several months without refrigeration making them an important source of nutrition in lean times.
Whereas the iron content of beef is 6 mg per 100 grams of dry weight mopane caterpillars pack a whopping 31 mg of iron per 100 grams.
and flavored with garlic lime juice and salt or with guacamole or dried chili powder. The grasshoppers are known as rich sources of protein;
Researchers have noted that the gathering of Sphenarium grasshoppers is an attractive alternative to spraying pesticides in fields of alfalfa and other crops.
Not only does this eliminate the environmental hazards associated with pesticide sprays it also gives the local people an extra source of nutrition and income from the sale of grasshoppers.
when cooked lightly in hot coals the skin develops the crisp flavorful texture of roast chicken.
African palm weevil A delicacy among many African tribes the palm weevil (Rhychophorus phoenicis) is collected off the trunks of palm trees.
A 2011 report from the Journal of Insect Science found that the African palm weevil is an excellent source of several nutrients such as potassium zinc iron and phosphorous as well as several amino acids and healthy
The insects are a rich source of important nutrients including protein iron potassium and phosphorus. Because stink bugs release a noxious scent they are eaten not usually raw
They are raised in The netherlands for human consumption (as well as for animal feed) partly because they thrive in a temperate climate.
Mealworms are also comparable to beef in terms of protein content but have a greater number of healthy polyunsaturated fats.
It is a fungal infection consisting of several different species of fungus that feeds on keratin the substance found in hair nails and the outer layer of skin within humans and domesticated animals.
and increasingly popular delicacies (in South america) have more fur and faster metabolisms than any true pig.
