Seasonal Vegetables: Spring Cleaning for the Body?

Q. Taught by my grandmother, I practice the time-honored tradition of eating spring greens: dandelions, burdock, stinging nettles, pigweed, lamb’s quarters, plantain, shepherd’s purse, garlic mustard, chickweed, cleavers, and so on. What does modern nutrition have to say about this? Are these greens truly “blood cleansing” or “liver cleansing?

A. In traditional Chinese acupuncture, each season is associated with a different organ and spring is the season of the liver. Many other traditional and alternative healing systems teach that certain plants “cleanse” or “strengthen” the blood or other organs.  You won’t find too much about that in Western nutrition science, though.

Wheat-Free Baking: Are Alternative Flours Healthier?

Can You Trust the Nutrition Facts?

Q.  How accurate are the calorie counts on nutrition facts labels? What about the nutrition information at restaurants? Is anyone checking them for accuracy?

A.  Consumers are often surprised–and dismayed–to learn that the information on nutrition facts labels is not nearly as accurate or reliable as they imagined.   Part of this is built into the system.   The FDA allows manufacturers and packagers a surprisingly wide margin of error–the information can be off  by 20% in either direction and still be in compliance.   For example, if the nutrition facts label says that a food contains 300 calories, it may actually contain anywhere from 240 to 360 calories.

Low Blood Sugar? Maybe Not.

Q. I have a lot of trouble with low blood sugar.  Any tips for what I should or shouldn’t be eating to help manage this?

A. My first question would be whether low blood sugar (hypoglycemia) is really the problem.

Several years ago, my sister told me she had problems with low blood sugar.  She hadn’t actually been to see a doctor. But she’d noticed that when she felt head-achy, queasy, or shaky (which was fairly often), drinking some juice or eating some crackers usually made her feel better–for a little while. She started carrying little boxes of raisins and animal crackers around in her purse and eating them throughout the day to keep her blood sugar from dipping.

As she told me all of this, I wondered if her “treatment plan” was actually part of the problem.  Continue reading “Low Blood Sugar? Maybe Not.” >
