THE 'GOOD FAT' WE NEED MORE OF VIEW ONLINE

GOOD FAT VS. BAD FAT

This week: A refresher course on COVID-19; the "good" fat our bodies need more of; why BMI is not a reliable indicator of health; why some of us can't digest milk; you might be drinking water all wrong; the strange truth about phantom pregnancies.

PHOTOGRAPH BY JOHN TULLY, BLOOMBERG/GETTY IMAGES COVID is back with a vengeance. Here's a refresher on everything you forgot. In the last week of August, deaths from COVID-19 were up 10 percent from the previous week thanks a new group of infectious Omicron variants. With cases and hospitalizations on the upswing, here are some reminders and recommendations about how to protect yourself and what to do if you think you have the virus or get sick, from the proper way to swab to how long to isolate, and guidelines on Paxlovid.

PHOTOGRAPH BY MARTY CHOBOT, NAT GEO IMAGE COLLECTION ‌ ‌ ‌ ‌ FROM THE ARCHIVES‌ ‌ ‌  Not all fat is bad for us. This 'good fat' could keep us youthful. The fat most people picture is known as white fat. But you're also born with brown fat, which is metabolically efficient in that it burns lots of calories—but we lose most of it as we age.

PHOTOGRAPH BY LUCA LOCATELLI, NAT GEO IMAGE COLLECTION Most of us are lactose intolerant. So why do we drink cow's milk? Dairy is an essential part of the modern American diet, but as the rise of coconut milk, cashew butter, and oat yogurt suggests, many of us can't digest it very well—68 percent of us, in fact. The truth is, drinking milk into adulthood—let alone another animal's—is strange behavior in the animal kingdom, and it has had a lot of big, weird effects.

THE STRANGE TRUTH ABOUT PHANTOM PREGNANCIES

PHOTOGRAPH BY VCG WILSON, CORBIS/GETTY IMAGES Back in 1555, Queen Mary became the first documented case of a very rare phenomenon called pseudocyesis. Sometimes called false, hysterical, phantom, or delusional pregnancy, pseudocyesis manifests most or all symptoms of pregnancy—but no fetus. Here's a look at this mysterious condition.
