When you lose fat, you exhale most of it. That sounds strange, but it is what the chemistry says. Your body stores fat as molecules made of carbon, hydrogen, and oxygen. When cells break those molecules down for energy, the carbon leaves your body mostly as carbon dioxide in your breath, and the hydrogen leaves … Read more
Most of the hormones in a glass of milk were made by the cow, not added by a farmer. Conventional dairy does contain hormones, but the word “conventional” on a milk label has nothing to do with hormone content.

It delivers more fiber, more protein, and more vitamins and minerals than refined white bread. That said, “whole wheat” on a label does not automatically make a loaf healthy.

As you lose weight, you burn fewer calories at rest and during activity, so the same diet that produced early loss can stop producing a deficit. This is normal physiology, not a sign that you have failed … Read more
Freezing is the most reliable way to preserve crab at home. Cooked crab meat keeps about three to four months in a freezer held at 0°F (-18°C) or colder, and live crab should be cooked before freezing rather than frozen alive. Canning crab is possible only with a pressure canner, and the safety margins are … Read more
Vitamin B12 does not treat anxiety or depression on its own, but a deficiency in this vitamin can cause symptoms that look like both. Correcting a confirmed deficiency often improves mood, energy, and mental clarity. For people with normal B12 levels, there is no good evidence that taking extra improves anxiety or depression. That distinction … Read more
The short answer surprises most people: the FDA does not have a definition of a “healthy food label.” There is no official label, seal, or stamp called “healthy” that the agency grants to foods. What the FDA does have is a specific rule for when a food product may use the word “healthy” as a … Read more

It most often affects the skin, mouth, eyes, liver, lungs, and joints, and it can appear months after transplant.
