Age-Specific Phenotypic Expression of Food Allergies

We in functional medicine have long been aware that children can start out with a clearly identified food allergy. As the child ages, the primary allergic symptoms fade and some other clinically relevant presentation appears in its place. For example: we’ll see a classic milk allergy in infancy — often as milk colitis.

SIBO and Chapped Lips: A Connection?

It’s winter. Chances are that if you live anywhere cold and dry, your lips have been chapped at least once this season. For most of us, we slather on the lip balm and all is well. But for some folks, the chapped lip experience is an entirely different animal: A relentless cycle of peeling and healing, peeling and healing that no amount of lip balm resolves.

The flu is here. Very early in the season, it’s already at epidemic proportions, hitting those most vulnerable to its ravages — kids and the elderly — as it does each year.

She launched into her story, retelling an all-too-familiar tale: She hadn’t stuck with her anti-inflammatory diet. Her food cravings, she explained, were out-of-control, and she was miserable….

Fingernails: A window into your metabolic soul

Nails. They’re a handy surface to decorate; they help us pick up objects, scratch an itch and protect our fingers and toes. But did you also know that nails can tell us a lot about your health and your well-being? For most of us, fingernails are completely renewed in about six months.
