In an ugly outside, the crushed fruit may pack more nutrition.
When Eliza, green orchard (Eliza Greenman) walk the tree a field, watched a bunch of defective buck fruits fruit, the fruit by the fungus, heat and insect pests, she felt a little joy. “My idea of orchard stress is absolutely obsessive,” greenman said. Mr. Greenman said he customized the apple cider that was transplanted and grown without pesticides, and that the apples were likely to be sweeter.
In an unofficial test, test the green man TB and parma apple without core, this is a high sugar varieties of southwest Virginia, found that the scars of apple sugar content than with a 2% to 5% higher immature apples on a tree. More sugar means higher alcohol content and better hard cider.
But she likes these ugly apples for another reason: they may be more nutritious and have higher levels of antioxidants. “I believe that stress can help create super fruit,” says greenman.
Ugly fruits and vegetables is the trouble today and scaly, dimples, deformity darling – and there are more and more sports to sell such a product, rather than pour it into the municipal landfill. As the salt newspaper reports, we need to find enough food to fill 44 skyscrapers every year. Why waste the perfect food? In April, some full-food stores in California will sell their first cosmetic products for the first time.
But some defective products have put up unexpected nutritional shocks – in order to survive their own battles?
We have suspected that this is the case with organic fruits and vegetables. A 2014 review of 343 studies found that organic products had lower levels of pesticide residues and 20 to 40 percent higher antioxidant content than conventional products. These antioxidants include flavonoids, phenolic acids, anthocyanins and carotenoids, all of which are the defense mechanisms of plants when plants are threatened by pests.
The authors suggest that organic crops may be under more pressure because they may accept less pesticides, lower doses and less lethal effects.
Another study of conventional and organic apple varieties found that organic apples contain high levels of antioxidant phenol and acid. The authors note: “regular consumption of fruit acids helps prevent disease and metabolic disorders, and we recommend that the consumption area be organically grown rather than integrated.
The ugly fruit actually bears the obvious scars of their successful battles – the dimples or the scars of a bite or bite of an insect or a bite. Greenman’s ideal is a real wild apple, a defense in nature – proof of defects in cosmetics. She points out that, although not all of the pests and diseases are benign, but some of the common apple violation is caused by a harmless fungus black (black) and flying spots (black spots), but does not damage the taste or texture, infect humans. These spots are the result of plants’ resistance to environmental pollution – based on their antioxidant defences. Greenman suspects that the ugly scars may reflect higher nutrition.
She may be right. A study has shown that apples that cover the scab have a healthier antioxidant phenolic compound called phenylalanine than the unscabbed apple peel. Another study showed that apple leaves infected with scab have 10 to 20 percent of phenolic compounds. A similar study found that resveratrol in high concentrations of grape leaves was affected by a fungus or exposed to ultraviolet light. A study of the Japanese tiger cane, a long tradition of herbs used in Chinese and Japanese herbs, found that common fungal infections increased the levels of resveratrol. Resveratrol is an antioxidant that is well studied for its potential heart protection. All of these antioxidants protect plants and protect people who eat them.
That doesn’t mean we should switch from traditional agriculture or make hard and fast assumptions about crops, says Brian Ward, an environmental biologist at clemson university. “There are a number of factors contributing to the antioxidant content,” ward said. “they are responsible for traditional and organic agriculture research. “The most important factor is the plant itself – which is variety, it is genetic, followed by soil, mineral content, whether or not to use traditional or organic fertilizer, but there are some interesting data, insect or disease, they will produce the metabolites are good for us. ”
Mr. Greenman’s insights drew the attention of Martin l. Pall, a professor emeritus at Washington state university. ‘we have our own, powerful protective mechanisms that can be activated by compounds in fruits and vegetables,’ Mr. Pall says. In fact, in a recent study, he suggested that these antioxidants might be used as a mild stressor to push our repair mechanisms to speed. They activate a molecule called Nrf2 in our cells, which itself triggers more than 500 genes, most of which have cellular protection.
“This is true of compounds like resveratrol,” he said. “This part is very clear.” He says there is evidence that other plant compounds under stress may also be good for our health, but these benefits are not well documented.
Rather, we have evolved with plants that benefit us from our compounds. He noted that known longevity diets, such as the traditional Mediterranean and Okinawa cuisine, are these compounds and antioxidants.
So, backyard gardeners, rejoice: your imperfect product may be more perfect than you think. Next time you are hesitant about a defective fruit, remember that it may be a tenacious survivor’s gift of hidden nourishment.
