eBook Friday: Hallucinations

Hallucinations, by Oliver Sacks

Have you ever seen something that wasn’t really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing?

Hallucinations don’t belong wholly to the insane. Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people. People with failing eyesight, paradoxically, may become immersed in a hallucinatory visual world. Hallucinations can be brought on by a simple fever or even the act of waking or falling asleep, when people have visions ranging from luminous blobs of color to beautifully detailed faces or terrifying ogres. Those who are bereaved may receive comforting “visits” from the departed. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one’s own body.

Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them. As a young doctor in California in the 1960s, Oliver Sacks had both a personal and a professional interest in psychedelics. These, along with his early migraine experiences, launched a lifelong investigation into the varieties of hallucinatory experience.

Here, with his usual elegance, curiosity, and compassion, Dr. Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organization and structure of our brains, how they have influenced every culture’s folklore and art, and why the potential for hallucination is present in us all, a vital part of the human condition.

eBook Friday: Whole: Rethinking the Science of Nutrition

Whole: Rethinking the Science of Nutrition, by T. Colin Campbell

What happens when you eat an apple? The answer is vastly more complex than you imagine.

Every apple contains thousands of antioxidants whose names, beyond a few like vitamin C, are unfamiliar to us, and each of these powerful chemicals has the potential to play an important role in supporting our health. They impact thousands upon thousands of metabolic reactions inside the human body. But calculating the specific influence of each of these chemicals isn’t nearly sufficient to explain the effect of the apple as a whole. Because almost every chemical can affect every other chemical, there is an almost infinite number of possible biological consequences.

And that’s just from an apple.

Nutritional science, long stuck in a reductionist mindset, is at the cusp of a revolution. The traditional “gold standard” of nutrition research has been to study one chemical at a time in an attempt to determine its particular impact on the human body. These sorts of studies are helpful to food companies trying to prove there is a chemical in milk or pre-packaged dinners that is “good” for us, but they provide little insight into the complexity of what actually happens in our bodies or how those chemicals contribute to our health.

In The China Study, T. Colin Campbell (alongside his son, Thomas M. Campbell) revolutionized the way we think about our food with the evidence that a whole food, plant-based diet is the healthiest way to eat. Now, in Whole, he explains the science behind that evidence, the ways our current scientific paradigm ignores the fascinating complexity of the human body, and why, if we have such overwhelming evidence that everything we think we know about nutrition is wrong, our eating habits haven’t changed.

Whole is an eye-opening, paradigm-changing journey through cutting-edge thinking on nutrition, a scientific tour de force with powerful implications for our health and for our world.
