Agriculture: The worst mistake in human history
Like it or not, humans are animals. And like all other animals, we are biologically adapted to a diet "in appropriate species" and lifestyle.
When animals eat and live in accordance with the environment to which they are suited, they . thrive cats, with their sharp and short tract teeth have evolved to be carnivores, so when we kibble rich cereals infants, they develop kidney problems and other ailments cows naturally graze on grass. when they eat too much grain, harmful bacteria proliferate and make them sick. We humans face a similar shift. Our biology and genes adapted to a particular environment. While the environment has changed much faster than we could adapt -with some important exceptions which I will cover later in this chapter. the result?
for most of our existence, we humans lived as hunter-gatherers of the Paleolithic, living off of the meat we hunted we caught fish and vegetables, fruits and tubers we made the move. The agricultural revolution dramatically changed our food supply and lifestyles. We learned to stay put, planting crops and domesticating animals such as cows, sheep, goats and pigs. The first farmers were given foods than their predecessors of hunter-gatherers do not eat, such as cereals, milk and meat from domestic animals, legumes and other crops.

While scientists have argued that these developments we allowed to flourish socially and intellectually, the consequences of the passage of a Paleolithic to agricultural food and lifestyle have been disastrous for human health. In evolutionary terms, 11,000 years is a wink, not long enough for humans to fully adapt to this new way of eating. That is why the scientific and influential author Jared Diamond called agriculture "the worst mistake in human history." He argued that hunter-gatherers "practiced the most successful lifestyle and most durable of human history" and were all but guaranteed a healthy diet because of the diversity and density of food nutrients they consume. Once we changed diet and became more sedentary, our naturally robust health began to decline.
Our Paleo ancestors Did not die young?
A common question I hear from skeptics Paleo is something along the lines of "Why should I eat Paleo? Did not the stone age die before their thirtieth birthday?"
It is true that, on average, our ancestors died Paleo younger. However, these averages do not include the largely absent challenges of our modern lives: high infant mortality, violence and accidents, infectious diseases and lack of modern medical care. Hunter-gatherers had infant mortality rate about 30 times higher than those of the United States early childhood mortality rates more than 100 times higher today. These infant mortality and childhood higher rates were caused by accidents, trauma, exposure to the elements, violence, war, and acute infectious disease issues which, fortunately, few of us face today. These premature deaths have had the net effect of dragging down the average life expectancy. If 10 people, three died in infancy, two died during childhood exposure to the elements and two died in adolescence in the war, although the other three lived a long life, good health, the average life span in this hypothetical group would be even shorter.
Recent research that had high infant mortality rates of our Paleolithic ancestors into account suggests that if they survived childhood, they had an average life span roughly equivalent to those living in industrialized societies, with a range from 68 to 78 years. More importantly, they have reached that age without any signs or symptoms of chronic, inflammatory and degenerative diseases that we consider "normal" in developed countries - including obesity, type 2 diabetes, gout, hypertension, cardiovascular disease and cancer. Of course, those of us living in modern industrialized societies could live a little longer than average acculturated hunter-gatherers. But most of our elderly people suffer from painful and debilitating diseases, take multiple medications daily, and a reduced quality of life.
Fortunately, we do not have to choose between eating like our ancestors or reap the benefits of modern medicine. We can combine them to get the best of both worlds and enjoy long life without degenerative diseases that are so common in the industrialized world.

Tell a professional risk. A former director of the franchise of McDonald in Porto Allegre, Brazil, received $ 17.500 reward to gain 65 pounds. more than 12 years on the job, the AP.
Judge Joao Filho ruled on the lawsuit filed against the company by the 32-year-old former employee on 26 October, stating that McDonald would pay $ 17.500 because the employee inflated about 155 lbs. to 231 lbs. while working at the restaurant in the south of Brazil. ( More about Time.com: Summer Journey Time - The food chain that binds us all).
The applicant says that because customers undercover hired McDonald to visit the restaurants chance and report on quality, he felt compelled to try everything on the menu to ensure the food was at the height . He said he also provided free meals of burgers, fries and ice, which contributed to its excessive weight gain in employment.
The judge agreed, apparently, but said McDonald could appeal the decision. The company said it is contemplating his options. ( More on Time.com: Top 10 worst fast food meals)

This old standby about savoring a pint of ice cream to get over a breakup? Counterproductive, according to a large new study that found a link between consumption of trans fat and increased risk of depression.
For the study, researchers in Spain followed the eating habits, lifestyles and mental health of college graduates 12.059 (average 37.5 years) for six years. None of the participants had depression at the beginning of the study; in the end, the researchers identified 657 new cases, which were self-reported by the participants completed questionnaires every two years. ( More on Time.com: 5 Better-For-You Morning Meals)
The researchers found that the risk for increased depression that trans fat consumption increases. low power consumption, which barely ate at all trans fats.
The study also found that people who ate a lot of monounsaturated and polyunsaturated fats, like those found in olive oil had a lower risk of depression - but this association decreased when the researchers controlled for other dietary factors such as the respect of the Mediterranean diet.
The data were collected as part of the "Seguimiento Universidad de Navarra" (SUN) project - a long-term cohort study on the health study of nurses in long-term model, funded by the US government. ( More on Time.com: Can a Veggie-Rich diet make you more beautiful)
The results of the study may be particularly bad news for Americans. While the Spanish average receives about 0.4% of its calories from trans fats - mostly from dietary sources or natural, such as milk, butter, meat and cheese - Americans log a average of 2.5% of total calories from trans fats. Americans not only eat more comprehensive, but also eat food worst quality, get a lot of trans fats from sources such as processed snack foods and fried or fast foods.
The authors also note that high consumption of trans fat is a known risk factor for cardiovascular disease, and many people with cardiovascular disease are depressed; both conditions may share a common underlying pathway. Reported the Los Angeles Times
In countries where the average trans fat consumption is high, such as the United States, the contribution of unhealthy fats to depression can be even stronger, said the researchers, universities of Navarra and Las Palmas.
Many people with heart disease also have depression, the authors noted. It could be that trans fats contribute to both disorders through a similar mechanism. Bad fat increases inflammation in the body. In the heart, which contributes to the accumulation of plaque which may cause heart disease. In the brain, substances secreted by inflammation can interfere with the neurotransmitters that affect mood.
The study can not say for sure if eating trans fats contributing to depression or whether people who were predisposed to depression ate more poor quality schemes. But the authors excluded depression cases that were diagnosed in the first two years of the study, which reinforced the association. ( More on Time.com: 10 New Diet Books 2011)
"When you exclude the first case, you can be sure that the event occurred after four, five years are not present at the beginning, "said study author Miguel Angel Martinez-Gonzalez on National post suggesting that," first, it is the trans fat, then it is depression. "
therefore, by devouring a carton of chocolate ice cream might make you feel good in the moment, you may just be trading short-term pleasure for long term risk increased depression.

Losing is hard enough. Keeping it off is even harder. Now a new study by Penn State researchers suggest that the techniques that work for losing weight are not necessarily the same as those that help you stay slim.
First, researchers surveyed more than 1,100 people who had reached a significant loss of weight and kept it. The researchers identified 36 practical weight loss and weight-maintenance at least 10% of the group used.
Next, the researchers conducted a national telephone survey of overweight (with a BMI of 25 or higher) who had tried to lose weight and keep it with varying success: about 11% reported losing weight successfully, defined as the loss of at least 10% of body weight, and 21% were able to maintain that loss for at least one year. The researchers asked how often they used their 36 previously identified techniques: "Rarely or never" "often or very often" or
The survey found that people who have lost weight. successfully done so to participate in weight loss programs, reductions on sugar and carbohydrates, eat healthy snacks, not skipping meals and participation in different types of exercise.
no all techniques that led to the initial weight loss, however, were associated with weight maintenance ,. Continually setting up an exercise regimen helped people lose weight, for example, but those who have kept the weight off tend to stick with a consistent exercise program. This may be because testing with a variety of workout routines can help people as they try to lose weight, but once they found what works for them, they tend to stick with it for maintenance.
The study noted that four strategies have been associated with weight maintenance, but no loss:
- A diet rich in low-fat proteins
- Following a consistent exercise program
- Rewarding yourself to diet and exercise
- remind you why you need to lose weight
"It seems a little like love and marriage," study author Dr. Christopher Sciamanna, professor of medicine and public health sciences at Penn State College of medicine, told WebMD. "What you come to the altar is likely to be quite different from what helps you stay married long term. [And] not recognizing this transition and adaptation of different practices also get you in trouble "
Yet, say many experts in nutrition and obesity, the underlying fundamentals of weight loss and maintenance are the same :. You have to eat a healthy diet and increase your exercise. People who lose weight and keep it tend to eat healthier foods significantly and do a lot more than the average American exercise.
But what can move between phases of weight loss and maintenance is the state of mind of a person, rather than focus on the loss of an active short-term weight, the people need to start focusing on the long term, permanent lifestyle changes and behavior if they want to keep the weight that was lost. The key, experts agree, is motivation, not necessarily the details of your weight loss program.
The study had some limitations, including the fact that the weight and behavior of all respondents were self-reported. The study appears in the American Journal of Preventive Medicine .
