hsph.harvard.edu —                                                        Fill half of your plate with vegetables and fruits.  The more color, and the more variety on this part of the plate, the better. Potatoes and French fries don't count as vegetables on the Healthy Eating Plate, because they are high in fast-digested starch (carbohydrate), which has the same roller-coaster effect on blood sugar and insulin as white bread and sweets. These surges, in the short term, can lead to hunger and overeating, and in the long term, can lead to weight gain, type 2 diabetes, and other health problems. Save a quarter of your plate for whole grains—not just any grains: Whole grains—whole wheat, brown rice, and foods made with them, such as whole wheat pasta—have a gentler effect on blood sugar and insulin than white bread, white rice, and other so-called “refined grains.” That’s why the Healthy Eating Plate says to choose whole grains—the less processed, the better—and limit refined grains. Put a healthy source of protein on one quarter of your plate:  Chose fish, chicken, beans or nuts, since these contain beneficial nutrients, such as the heart-healthy omega-3 fatty acids in fish, and the fiber in beans. An egg a day is okay for most people, too (people with diabetes should limit their egg intake to three yolks a week, but egg whites are fine). Limit red meat—beef, pork, and lamb—and avoid processed meats—bacon, cold cuts, hot dogs, and the like—since over time, regularly eating even small amounts of these foods raises the risk of heart disease, type 2 diabetes, and colon cancer. Use healthy plant oils. The glass bottle near the Healthy Eating Plate is a reminder to use healthy vegetable oils, like olive, canola, soy, corn, sunflower, peanut, and others, in cooking, on salad, and at the table. Limit butter, and avoid unhealthy trans fats from partially hydrogenated oils. Drink water, coffee or tea. On the Healthy Eating Plate, complete your meal with a glass of water, or if you like, a cup of tea or coffee (with little or no sugar). (Questions about caffeine and kids? Read more.) Limit milk and dairy products to one to two servings per day, since high intakes are associated with increased risk of prostate cancer and possibly ovarian cancer. Limit juice to a small glass per day, since it is as high in sugar as a sugary soda. Skip the sugary drinks, since they provide lots of calories and virtually no other nutrients. And over time, routinely drinking sugary drinks can lead to weight gain, increase the risk of type 2 diabetes, and possibly increase the risk of heart disease. Stay active. The small red figure running across the Healthy Eating Plate’s placemat is a reminder that staying active is half of the secret to weight control. The other half is eating a healthy diet with modest portions that meet your calorie needs. Read 20 tips for staying active.

ncbi.nlm.nih.gov — A 25% discount on fruits and vegetables was effective in stimulating purchases of those products and did neither lead to higher expenditures in unhealthier food categories nor to higher total calories purchased.   A randomized controlled trial with two research conditions was conducted: a control condition with regular prices (n = 52) and an experimental condition with a 25% discount on fruits and vegetables (n = 63). The experiment was carried out using a three-dimensional web-based supermarket, which is a software application in the image of a real supermarket. Data were collected in 2010 in the Netherlands. Participants received a fixed budget and were asked to buy weekly household groceries at the web-based supermarket. Differences in fruit and vegetable purchases, differences in expenditures in other food categories and differences in total calories were analyzed using independent samples t-tests and multiple linear regression models accounting for potential effect modifiers and confounders.   Waterlander WE, Steenhuis IH, de Boer MR, Schuit AJ, Seidell JC   Int J Behav Nutr Phys Act. 2012 Feb 8;9(1):11

tandfonline.com — Approximately 200 studies that examined the relationship between fruit and vegetable intake and cancers of the lung, colon, breast, cervix, esophagus, oral cavity, stomach, bladder, pancreas, and ovary are reviewed. A statistically significant protective effect of fruit and vegetable consumption was found in 128 of 156 dietary studies in which results were expressed in terms of relative risk.   For most cancer sites, persons with low fruit and vegetable intake (at least the lower one‐fourth of the population) experience about twice the risk of cancer compared with those with high intake, even after control for potentially confounding factors. For lung cancer, significant protection was found in 24 of 25 studies after control for smoking in most instances. Fruits, in particular, were significantly protective in cancers of the esophagus, oral cavity, and larynx, for which 28 of 29 studies were significant.   Strong evidence of a protective effect of fruit and vegetable consumption was seen in cancers of the pancreas and stomach (26 of 30 studies), as well as in colorectal and bladder cancers (23 of 38 studies). For cancers of the cervix, ovary, and endometrium, a significant protective effect was shown in 11 of 13 studies, and for breast cancer a protective effect was found to be strong and consistent in a meta analysis.   It would appear that major public health benefits could be achieved by substantially increasing consumption of these foods.

veganhealth.org — Iodine Status of Vegetarians Iodine is only found inconsistently in plant foods, depending on the iodine content of the soil. Food grown near the ocean tends to be higher in iodine. Iodine is consistently found in only a few foods such as dairy products (iodine solutions are used to clean the cows' teats and dairy equipment and end up in the milk) and seafood (including seaweed). In a 2011 cross-sectional study from the Boston area, urinary iodine levels of 78 lacto-ovo vegetarians and 62 vegans were measured. People with previously diagnosed thyroid problems were excluded from the study. According to the authors, "Population iodine sufficiency is defined by median urinary iodine concentrations 100 µg/l or greater in adults and 150 µg/l or greater in pregnancy." Median urinary iodine concentration of vegans (79 µg/l; range 7 – 965 µg/l) was significantly lower than vegetarians (147 µg/l; range 9 – 779 µg/l). Markers of thyroid function were similar in both groups and in the normal range; one vegan and no vegetarians had abnormal thyroid function. Most of the vegans were making no effort to insure adequate iodine intake. Iodine deficiency is not as much of a problem for U.S. vegans as it is for European vegans, whose food supply contains less iodine. Studies have shown that vegans in Europe (where salt is minimally iodized) who do not supplement (as well as those who oversupplement) have indications of abnormal thyroid function.

ncbi.nlm.nih.gov — The aim of the study was to investigate the frequency and severity of dental erosions and its association with nutritional and oral hygiene factors in subjects living on a raw food diet. As part of a larger dietary study 130 subjects whose ingestion of raw food was more than 95% of the total food intake were examined. The median duration of the diet was 39 (minimum 17, maximum 418) months. Before the clinical examination, the participants answered questionnaires and recorded their food intake during a 7-day period. Dental erosions were registered using study models. As a control 76 sex- and age-matched patients from our clinic were randomly selected. The raw food diet records showed the median daily frequency of ingesting citrus fruit to be 4.8 (minimum 0.5, maximum 16.1). The median intake of fruit was 62% (minimum 25%, maximum 96%) of the total, corresponding to an average consumption of 9.5 kg of fruit (minimum 1.5, maximum 23.7) per week. Compared to the control group subjects living on a raw food diet had significantly (p</=0.001) more dental erosions. Only 2.3% of the raw food group (13.2% of the controls) had no erosive defects, whereas 37.2% had at least one tooth with a moderate erosion (55.2% of the controls) and 60.5% had at least one tooth with a severe erosion (31.6% of the controls). Within the raw food group no significant correlation was found between nutrition or oral health data and the prevalence of erosions. Nevertheless, the results showed that a raw food diet bears an increased risk of dental erosion compared to conventional nutrition.

nature.com — Modification of immune responses to exercise by carbohydrate, glutamine and anti-oxidant supplements Immunosuppression in athletes involved in heavy training is undoubtedly multifactorial in origin. Training and competitive surroundings may increase the athlete's exposure to pathogens and provide optimal conditions for pathogen transmission. Heavy prolonged exertion is associated with numerous hormonal and biochemical changes, many of which potentially have detrimental effects on immune function. Furthermore, improper nutrition can compound the negative influence of heavy exertion on immunocompetence. An athlete exercising in a carbohydrate-depleted state experiences larger increases in circulating stress hormones and a greater perturbation of several immune function indices. The poor nutritional status of some athletes may predispose them to immunosuppression. For example, dietary deficiencies of protein and specific micronutrients have long been associated with immune dysfunction. Although it is impossible to counter the effects of all of the factors that contribute to exercise-induced immunosuppression, it has been shown to be possible to minimize the effects of many factors. Athletes can help themselves by eating a well-balanced diet that includes adequate protein and carbohydrate, sufficient to meet their energy requirements. This will ensure a more than adequate intake of trace elements without the need for special supplements. Consuming carbohydrate (but not glutamine or other amino acids) during exercise attenuates rises in stress hormones, such as cortisol, and appears to limit the degree of exercise-induced immunosuppression, at least for non-fatiguing bouts of exercise. Evidence that high doses of anti-oxidant vitamins can prevent exercise-induced immunosuppression is also lacking.

fruitarian.net — Fruit contains vital elements to make our body work and there is a great energy in their juices. These juices do not burden our system, but  pass easily through it, giving the body a more efficient energy system. Imagine a world where people ate only fruits. This will result in a healthy abundance of fruit trees, giving nutritious food to be enjoyed by those who wish to live an energetic and healthy life. The world will  transform in beauty to the way it used to look earlier with an increase in tree populations cleaning the air and offering hiding environment for animals of the nature, many of them are already endangered. When we  start eating only fruits and nuts the difference is felt very quickly. A sensation of integrity and a wave of energy spreads through the body. Another benefit to our health could be a psychological one, if  we think we are not causing the death of animals to survive. There is no need to make secret of the fact that when we consume meat, we are triggering a chain reaction together with all the other consumers, which will finally cause the death of a poor animal living somewhere out there, which we have never seen the face.The increase of our human races in the world and our wrong eating habits are the main reasons for the destruction of the forests and the right environmental conditions in which we live. The excessive grazing of the animals and raising of the crops do not permit the creation of a suitable flora which is necessary for the growth of the trees. This also means erosion, which takes away the fertile soil and poor peasants moving to the towns, which grow continually, creating more environmental and social problems. As for our bodies they are not designed to live sedentary lives in those towns. Degenerative diseases such as cancer, heart disease or osteoporosis strike us and we suffer.Fruitarian lifestyle could be a plan to stop the global warming and save the world as it will result the increase of the fruit trees everywhere in the world. It simply consists of collecting fruits from the trees, eating them and scattering their seeds around. By doing this, we will spread these fruit trees everywhere and will need no instruments to do that. Our bare hands are designed to collect and eat fruits. So there will be no need to harm the nature by processing, cooking and washing dishes.

discovermagazine.com — Thus passed the bulk of three years. Milton found that most of the time the howlers ate leaves and fruit in almost equal measure, but when seasonal fruits were in short supply, the animals filled up on leaves. Howler monkeys were finicky, though. They ate only tender, young leaves, and only the tips at that....They appear to use a collective information pool to locate their foods. They’ll just set off in a straight line right to it....The howlers conducted these expeditions over 75 acres, searching out as many as 25 species of plants daily. Some, like the Ceiba pentandra tree, were edible for only a few hours a year; others were available more often. Unerringly, the howlers tracked them down. The ranges of various howler troops overlapped, so Milton would occasionally come upon a tree filled with monkeys, with other groups in adjoining trees politely waiting their turn at the table. All of which suggested that the animals had an extraordinary collective memory, an unfailing sense of direction, refined social manners, and a built-in barometer of what foods were good for them.This aggregate intelligence allows infant howlers to mature quickly. After 12 to 14 months, howler mothers don’t want to see their babies again, Milton says. The babies soon declare independence and rely on the group for support.Still, despite the obvious group intelligence, the monkeys individually didn’t seem particularly smart to Milton. They were relatively dull and placid - and unobservant. I ate lunch for months in full view of dozens of howlers, and not one ever seemed to realize that I was eating, much less that what I was eating might be something they would enjoy, too, she says. You could make noises and slurp and carry on - whatever cognitive processes are required to identify the act of eating, they don’t seem to use them.But spider monkeys did. I saw them all the time when I was studying howlers, says Milton. They’d go roaring by like greased lightning. Spider monkeys are the same size as howlers, and the two animals share parts of each other’s ranges on Barro Colorado. But there the similarities end. Whereas howlers travel through the canopy on all fours, spiders swing along like Tarzan. Unlike the placid howlers, spiders are playful and mischievous. They’re terrible teases, says Milton. And they’re mean little devils. They remind me of people, she confides with a laugh. Although not specifically any of my close friends.Spider monkeys had no trouble recognizing Milton’s lunch. ‘Food!’ they’d shout. ‘Let’s see if we can get it!’ They’d swing down toward you; they’d threaten you. They know what a banana is. They have a keen idea of what a peanut butter sandwich is. You simply cannot eat in front of them.Intrigued, Milton decided she’d add spider monkeys to her observations. She thought it might be interesting to compare how the two species evolved from a common ancestor. But while the comparatively sedate howlers were a researcher’s dream, dealing with the spider monkeys was something else again. They were too fast for me, says Milton. So I hired a young man to work with me. He would run through the forest as fast as he could, following the monkeys, and I would come behind. We communicated by calls. ‘Whooooo!’ Like that. The sound really carries through the forest.When the barnstorming spider monkeys found food, they’d finally screech to a stop, allowing Milton to catch up. They’d just stuff themselves. Then they’d lie around and take naps.Unlike the howlers, Milton discovered, the spider monkeys almost exclusively ate fruit, which often made up 90 percent of their diet. Even when fruit was out of season or in short supply, it constituted over half their food. But ripe fruit is even harder to find than tender leaves. To get enough, the 18 spider monkeys on the island would resort to splitting up and trying their luck on their own. During most of the year the distribution patterns of their foods are such that if they went around in a big group, there wouldn’t be enough at any one site to feed everyone, says Milton. So they’d spend almost the whole day foraging in small subunits or by themselves. Then around twilight they’d begin to call and coalesce, and then they’d spend the night together.As a result of this extended exploring, the spiders’ territory was huge, some 750 acres, ten times that of the howler monkeys. And that’s a conservative estimate, says Milton. Two thousand acres might be right. If the howlers displayed impressive feats of memory and direction by finding young leaves, the spider monkeys’ long-distance forays after fruit were astounding. Within an enormous area they had to remember at least 100 species of fruit and where to find thousands of fruit-bearing trees. They had to remember when each fruit was ripe, how best to approach the site, and how best to return home. If a howler forgot a food source or a travel route, the others were there to take up the slack. The spiders, though, had to fend for themselves.And they had to know how to stay in touch. Howler monkeys tended to be quiet, communicating through subtle clucks and rattles in the throat, except at daybreak, when their eerie howls declared. ...Spider monkeys, on the other hand, were conspicuously noisy. They’d yelp and cry, whinnying like horses, barking like dogs - sometimes for hours at a time. ...And in contrast to the howlers’ community messages, spider monkeys believed in individual expression. Spider monkey vocalizations are generally individualistic. ...All that variety and independence requires lots of training. As a result, infant spider monkeys mature slowly. They are nursed and carried by their mothers for two years, and they continue to associate almost exclusively with her until they’re about three or three and a half years old. ...Why were the two monkeys so dissimilar? Milton wondered about the differences in their diets. Howler monkeys ate mainly leaves, sometimes exclusively leaves, a low-quality source of nutrition. Leaves are plentiful and relatively high in protein, but they’re low in energy-rich carbohydrates. They also consist of some 60 percent indigestible fiber and sometimes contain toxic chemicals. How in the world did howlers get enough energy from this unpromising diet? And why did they stick to it even during seasons when there was plenty of ripe fruit in the forest?Fruits are loaded with easily digested carbohydrates and are relatively low in fiber - they’re high-quality, nutritious food. They mean instant energy. On the other hand, fruits provide little protein. So, Milton wondered, how did spider monkeys get enough protein? And why, when fruits were scarce, didn’t they fill up on leaves, as howlers did? Why did they go to such extremes to find fruits?Milton began finding some answers to these questions in 1977, when she returned to Barro Colorado after completing her doctoral thesis. She soon conducted an experiment measuring how long it took the monkeys to process their food. I needed to look at internal features of the monkeys, she says. I thought that perhaps the structure of their guts or efficiency of their digestion might be influencing their behavior.She trapped howler and spider monkeys, confined them in pens, and fed them food in which she had concealed tiny plastic markers. I used a type of thin plastic material that I cut with very fine manicure scissors into little colored plastic worms, she explains. When the monkeys excreted the remains of their food, out came the markers. Milton could therefore measure the time it took any one meal to pass through a monkey’s digestive tract. The results were dramatic: howlers took 20 hours to digest their food, five times as long as spiders. ...When Milton came upon monkeys that had died in the forest, she took them back to the research station, dissected them, and measured their gastrointestinal tracts. She then confirmed her figures against published material on differential gut measurements in various primates. She found that the colons of howlers were considerably wider and longer than those of spider monkeys. Food had to travel much farther and remained much longer in howler guts, and the monkeys had room for much more bulk. As a result, bacteria had a chance to ferment masses of fibrous leaves in the monkeys’ colons, producing energy-rich fatty acids. Milton eventually found that howlers receive more than 30 percent of their daily energy from such fatty acids.... Spiders were far less efficient at extracting energy from the fiber in their diet - but they didn’t have to be efficient. They ate easily digestible fruits. By moving a steady stream of fruit through their gastrointestinal tracts every day, they obtained all the carbohydrates they needed and some of the protein. The rest came from supplements of young, tender leaves.It was a striking example of evolutionary adaptation. Each monkey’s physiology fit its particular diet. Spider monkeys couldn’t get away with eating a howler diet of mostly leaves. With their smallish guts, they’d never keep enough bulk around long enough for fermentation to provide energy. And howlers wouldn’t manage for long if they used the spider monkey tactic of eating fruit - their slow digestive tracts couldn’t process nearly enough of it. Besides, it took smarts to track down sufficient fruit, and Milton thought it unlikely that the howlers were up to the job. Nor was the howler diet of leaves up to the job of fueling the amount of brainpower necessary. The brain, a big, hungry organ, requires a disproportionate amount of energy, and leaves just don’t provide enough....The more I thought about it, the more it seemed to make sense that if you have a high-energy diet and widely distributed foods, you’re going to need a certain amount of ability to locate those foods. ...A scientist named Daniel Quirling had published extensive statistics about the sizes of primate brains. Spider monkey brains, he had determined, weigh twice those of howlers, 107 grams compared with 50.4. No wonder spiders are smarter....Compared with the howlers, spider monkeys were brighter and more lively. They matured more slowly and had more to learn; they made more ruckus, with a greater variety of vocalizations; they ate widely dispersed, high-energy foods that were harder to find--and their brains were twice as large. Why?As far as Milton was concerned, diet was the key to these discrepancies. Eating fruits fueled the evolution of the spider monkeys’ large brains. Says Milton, It would have been a feedback process in which some slight change in the monkeys’ foraging behavior conferred a benefit, which in turn permitted a modest improvement in the quality of their diet, which led to an excess of energy. Over generations, the monkeys that spent the energy on making their brain slightly bigger and more complex had an evolutionary advantage. Their improved brain allowed for more helpful changes in their behavior, and so on.Milton realized that if such a scenario was correct, similar differences in brain size should show up in other primates with similar differences in diet - monkeys and apes that eat fruits should have larger brains than their leaf-eating counterparts. Sure enough, when Milton checked the literature, she found the pattern held true. For example, of the three great apes, lively, quick chimpanzees, our closest animal relatives, have a bigger brain for their body size than do the slower, more placid gorillas and orangutans. Chimps take some 94 percent of their diet from plants, largely in the form of ripe fruits. Gorillas and orangutans eat 99 percent plant foods, but mainly lower-quality leaves, pith, even bark. Diet had to be the key to their disparate evolution.
