Lyme disease was once unheard of in western Pennsylvania, where Barbara Thorne, now an entomologist at the University of Maryland, spent time as a kid.

Thorne knew that if black-legged ticks are infected with bacteria called Borrelia burgdorferi, they can transmit Lyme to people and, that if untreated, symptoms can range from fever, fatigue and a rash, to serious damage to the joints, heart and nervous system.

Scott Gottlieb, the Food and Drug Administration commissioner appointed by the Trump administration, has this in common with Michelle Obama: He wants to know what's in the food he eats.

And this, it seems, includes calorie counts.

Now, the FDA has released its guidance on implementing an Obama-era rule that requires chain restaurants and other food establishments to post calories on menus or menu boards. The mandate was written into the Affordable Care Act back in 2010.

If you've put off starting a family, you're not alone.

In the U.S., the average age a woman gives birth to her first child has been rising. And, a study published Thursday in Human Reproduction shows dads are getting older, too.

In 1972, the average age of fathers of newborns in the U.S. was 27. Now, it's closer to 31 years old (30.9 years to be specific), the study finds.

Eating well has many known benefits. But a good diet may not be able to counteract all the ill effects of stress on our bodies.

A new study, published in Molecular Psychiatry, suggests stress can override the benefits of making better food choices.

By now, surely you've heard of the Mediterranean diet.

It's a pattern of eating that emphasizes fish, nuts, legumes, fruits, vegetables and olive oil — lots of olive oil.

The idea that fermented foods — including yogurt and kefir — are good for us goes way back. But could the benefits of "good bacteria" extend beyond our guts to our brains?

Nobel Prize-winning scientist Elie Metchnikoff (also known as Ilya Ilich Mechnikov) first observed a connection between fermented milk and longevity among Bulgarian peasants more than a century ago.

If you like the idea of zero or low-calorie sodas, but you're turned off by the artificial sweetener aspartame, you're not alone.

Sales of diet soda have fallen off significantly in the U.S. And when PepsiCo started asking consumers what they didn't like, aspartame was at the top of the list.

"It's literally the number-one complaint we've heard from diet-cola consumers as to why they're drinking less and less diet cola, " Seth Kaufman, a senior vice president for PepsiCo, tells The Salt.

It's not the salt shakers on our tables that explain why Americans consume way too much sodium. It's the processed foods we buy in grocery stores.

There's been a lot of buzz around the story that some inexpensive California wines, including a Charles Shaw (aka two-buck Chuck) white Zinfandel sold at Trader Joe's, have been found to contain traces of arsenic.

If you've ever watched Giada de Laurentiis make gooey chocolate-hazelnut spread or a rich carbonara pasta dish, you may have wondered: How can she cook like this and maintain her slim figure?
