"There are some tragic cases of children whose brains failed to develop because of their parents being ill-informed vegans," says David Benton, who studies the link between our diets and brain chemistry at Swansea University. In one example, the child was unable to sit or smile. In another, they slipped into a coma.
Later in life, the amount of B12 in a person's blood has been directly correlated with their IQ. In the elderly, one study found that the brains of those with lower B12 were six times more likely to be shrinking.
Even so, low B12 is widespread in vegans. One British study found that half of the vegans in their sample were deficient. In some parts of India, the problem is endemic — possibly as a consequence of the popularity of meat-free diets.
Herbs are a fantastic addition to your Parrot's diet, not only for their abundance of health benefits, but also in the variety they provide as part of a balanced diet. They can be presented in a chop, threaded through the cage bars, or even strung together as a shredding toy.

At its root, the problem we face is that we have entered a space age world with Stone Age genes – genes that evolved to produce jaws adapted to a hunter-gatherer diet. Today's jaws epidemic is concealed behind the commonplace. Its most obvious symptoms are oral and facial: crooked teeth (and the accompanying very common use of braces), receding jaws, a smile that shows lots of gums, mouth breathing, and interrupted breathing during sleep. A bother, but hardly an 'epidemic' – at least until one recognizes the relationship between malocclusion and a veritable host of downstream health consequences.

The watermelon originally came from Africa, but after domestication it thrived in hot climates in the Middle East and southern Europe. It probably became common in European gardens and markets around 1600. Old watermelons, like the one in Stanchi's picture, likely tasted pretty good — Nienhuis thinks the sugar content would have been reasonably high, since the melons were eaten fresh and occasionally fermented into wine. But they still looked a lot different.
That's because over time, we've bred watermelons to have the bright red color we recognize today. That fleshy interior is actually the watermelon's placenta, which holds the seeds. Before it was fully domesticated, that placenta lacked the high amounts of lycopene that give it the red color. Through hundreds of years of domestication, we've modified smaller watermelons with a white interior into the larger, lycopene-loaded versions we know today.
Of course, we haven't only changed the color of watermelon. Lately, we've also been experimenting with getting rid of the seeds — which Nienhuis reluctantly calls "the logical progression in domestication." Future generations will at least have photographs to understand what watermelons with seeds looked like. But to see the small, white watermelons of the past, they too will have to look at Renaissance art.

That’s because we eat a ton of meat, and the vast majority of it comes from factory farms. In these huge industrialized facilities that supply more than 90 percent of meat globally — and around 99 percent of America’s meat — animals are tightly packed together and live under harsh and unsanitary conditions.
“When we overcrowd animals by the thousands, in cramped football-field-size sheds, to lie beak to beak or snout to snout, and there’s stress crippling their immune systems, and there’s ammonia from the decomposing waste burning their lungs, and there’s a lack of fresh air and sunlight — put all these factors together and you have a perfect-storm environment for the emergence and spread of disease,“ said Michael Greger, the author of Bird Flu: A Virus of Our Own Hatching.
To make matters worse, selection for specific genes in farmed animals (for desirable traits like large chicken breasts) has made these animals almost genetically identical. That means that a virus can easily spread from animal to animal without encountering any genetic variants that might stop it in its tracks. As it rips through a flock or herd, the virus can grow even more virulent.
Greger puts it bluntly: “If you actually want to create global pandemics, then build factory farms.”
Not so long ago, we found out that Tokyo’s Akihabara Station has a bank of vending machines stocked with a huge array of delicious milk-based drinks, with all sorts of fruit, tea, and coffee flavorings to tempt you. But while those are great for quenching your thirst or satisfying your sweet tooth, what about when you’re feeling hungry?
