Many herbal supplements contain biologically active plant chemicals that can affect the body like drugs.

In my new story I explain:
• why plants produce toxic compounds
• how supplements concentrate them
• a real public health case that exposed the risk

Can you refreeze thawed meat?

Most people think the freezer is the problem.

It isn’t.

The real food safety risk happens before the meat ever goes back into the freezer.

I explain the science here:

Reheated rice isn’t the real danger.

The real food safety mistake happens hours earlier, when cooked rice sits at room temperature.

Here’s the science behind the myth and the simple rule that keeps leftover rice safe.

Food allergies don’t start with the first bite.

They may begin earlier — through the skin, microbiome, and immune training.

A 2.8M-child meta-analysis is changing how we think about eczema, antibiotics, and peanut exposure.

Ultra-processed food is really bad for health. These engineered, industrialized products make up more than 1/2 of US diets and are loaded with unhealthy non-food ingredients. But what actually happens in the body that makes UPFs so bad? This food expert explains how eating UPFs eats away at your body's cells and organs, and how the hidden risks play out over many years - without you realizing the damage until it's well underway.
