Early Indians: The Story of Our Ancestors and Where We Came From – Tony Joseph

Who are we Indians? Where did we come from? Many of us believe our ancestors have lived in South Asia since ‘time immemorial’. But, as it turns out, ‘time immemorial’ may not have been all that long ago. To tell us the story of our ancestry, journalist Tony Joseph goes 65,000 years into the past—when a band of modern humans, or Homo sapiens, first made their way from Africa into the Indian subcontinent.

Citing recent DNA evidence, he traces the subsequent large migrations of modern humans into India—of agriculturalists from Iran between 7000 and 3000 BCE and pastoralists from the Central Asian Steppe between 2000 and 1000 BCE, among others.

As Joseph unravels our history using the results of genetic and other research, he takes head-on some of the most controversial and uncomfortable questions of Indian history: Who were the Harappans? Did the ‘Aryans’ really migrate to India? Are North Indians genetically different from South Indians? And are the various castes genetically distinct groups?

This book relies heavily on path-breaking DNA research of recent years. But it also presents earlier archaeological and linguistic evidence—all in an entertaining and highly readable manner. A hugely significant book, Early Indians authoritatively and bravely puts to rest several ugly debates on the ancestry of modern Indians. It not only shows us how the modern Indian population came to be composed as it is, but also reveals an undeniable and important truth about who we are: we are all migrants. And we are all mixed.

Nexus: A Brief History of Information Networks from the Stone Age to AI – Yuval Noah Harari

For the last 100,000 years, we Sapiens have accumulated enormous power. But despite allour discoveries, inventions, and conquests, we now find ourselves in an existential crisis. The world is on the verge of ecological collapse. Misinformation abounds. And we are rushing headlong into the age of AI—a new information network that threatens to annihilate us. For all that we have accomplished, why are we so self-destructive?

Nexus looks through the long lens of human history to consider how the flow of information has shaped us, and our world. Taking us from the Stone Age, through the canonization of the Bible, early modern witch-hunts, Stalinism, Nazism, and the resurgence of populism today, Yuval Noah Harari asks us to consider the complex relationship between information and truth, bureaucracy and mythology, wisdom and power. He explores how different societies and political systems throughout history have wielded information to achieve their goals, for good and ill. And he addresses the urgent choices we face as non-human intelligence threatens our very existence.

Information is not the raw material of truth; neither is it a mere weapon. Nexus explores the hopeful middle ground between these extremes, and in doing so, rediscovers our shared humanity.

Prevent and Reverse Heart Disease: The Revolutionary, Scientifically Proven, Nutrition-Based Cure – Caldwell B. Esselstyn Jr.

Prevent and Reverse Heart Disease challenges conventional cardiology by posing a compelling, revolutionary idea-that we can, in fact, abolish the heart disease epidemic in this country by changing our diets. Drawing on the groundbreaking results of his twenty-year nutritional study, Dr. Caldwell B. Esselstyn, Jr., a former surgeon, researcher, and clinician at the Cleveland Clinic, convincingly argues that a plant-based, oil-free diet can not only prevent and stop the progression of heart disease, but also reverse its effects.

Furthermore, it can eliminate the need for expensive and invasive surgical interventions, such as bypass and stents, no matter how far the disease has progressed. Dr. Esselstyn began his research with a group of patients who joined his study after traditional medical procedures to treat their advanced heart disease had failed. Within months of following a plant-based, oil-free diet, their angina symptoms eased, their cholesterol levels dropped significantly, and they experienced a marked improvement in blood flow to the heart. Twenty years later, the majority of Dr. Esselstyn’s patients continue to follow his program and remain heart-attack proof.

Prevent and Reverse Heart Disease explains the science behind these dramatic results, and offers readers the same simple, nutrition-based plan that has changed the lives of his patients forever. In addition, Dr. Esselstyn provides more than 150 delicious recipes that he and his wife, Ann Crile Esselstyn, have enjoyed for years and used with their patients. Clearly written and backed by irrefutable scientific evidence, startling photos of angiograms, and inspiring personal stories, Prevent and Reverse Heart Disease will empower readers to take charge of their heart health. It is a powerful call for a paradigm shift in heart-disease therapy.

Gulp: Adventures on the Alimentary Canal – Mary Roach

“America’s funniest science writer” (Washington Post) takes us down the hatch on an unforgettable tour.

The alimentary canal is classic Mary Roach terrain: the questions explored in Gulp are as taboo, in their way, as the cadavers in Stiff and every bit as surreal as the universe of zero gravity explored in Packing for Mars.

Why is crunchy food so appealing? Why is it so hard to find words for flavors and smells? Why doesn’t the stomach digest itself? How much can you eat before your stomach bursts? Can constipation kill you? Did it kill Elvis?

In Gulp we meet scientists who tackle the questions no one else thinks of—or has the courage to ask. We go on location to a pet-food taste-test lab, a fecal transplant, and into a live stomach to observe the fate of a meal.

With Roach at our side, we travel the world, meeting murderers and mad scientists, Eskimos and exorcists (who have occasionally administered holy water rectally), rabbis and terrorists—who, it turns out, for practical reasons do not conceal bombs in their digestive tracts.
Like all of Roach’s books, Gulp is as much about human beings as it is about human bodies.

Gene Eating: The Science of Obesity and the Truth About Diets – Giles Yeo

In an age of misinformation and pseudo-science, the world is getting fatter and the diet makers are getting richer. So how do we break this cycle that’s killing us all?

Drawing on the very latest science and his own genetic research at Cambridge University, Dr Giles Yeo has written the seminal ‘anti-diet’ diet book. Exploring the history of our food, debunking marketing nonsense and toxic diet advice, and confronting the advocates of ‘clean eating’, Dr Giles translates his pioneering
research into an engaging, must-read study of the human appetite.

Inspiring and revelatory, Gene Eating is an urgent and essential book that will empower us all with the facts we need to establish healthy relationships with food – and change the way we eat.
