- Black cohost or red clover do not work better than a placebo in treating hot flashes and other menopausal symptoms. (published in Menopause by University of Illinois at Chicago)
- Ginkgo bilobadoes not help prevent or delay severe memory loss or Alzheimer’s, according to a study published in November in the Journal of the American Medical Association. Conducted in five medical centers, the study looked at more than 1,500 people, 75 and older, for six years. The herb, taken twice a day in standardized doses, did not reduce the rate of dementia or slow the development of Alzheimer’s, whether subjects began the trial with normal or impaired memory. This study adds to the substantial body of evidence that ginkgo extract does not prevent mental decline. (Journal of the American Medical Association).
More people are turning to kosher foods even if it costs more – not because they are Jewish but because they think these foods are safer, healthier, and of better quality. There is little published research comparing the safety of kosher and nonkosher foods. It is not purer or more wholesome, not necessarily more nutritious or flavorful, and has just as much sugar and fat than nonkosher. The salting process may reduce attachment of bacteria to the carcass surface and so they are easier to rinse off. But, this is not a sterilization process and you still need to handle the meat carefully. The kosher symbol is no guarantee of safety. Read the rest of this entry »
Regular sodas add the most sugar to a typical American’s diet.
It isn’t hard to reach—and far exceed—the new limits set for added sugar by the American Heart Association— 25 grams a day for women, 37. 5 grams for men (see page 1). Even foods like yogurt and baked beans may be loaded with extra sugar, beyond the sugar naturally in them. Sugar content varies among brands; the amounts below are averages. Many people consume more than the serving sizes listed. For example, we list a cola as 8 ounces, but soda cans are 12 ounces and bottles are 16 ounces or larger.
Beverages (8 oz) Added sugar (g) Read the rest of this entry »
Goji is actually a generic term given to various berries in the Lycium family that grow in Asia, where they’ve been consumed for centuries to supposedly promote good eyesight, agility, and longevity, among other benefits. Wolfberry is another common name for these small, red, tangy berries. There is no evidence to support the claim that they prevent macular degeneration and cataracts. Other claims—that they ward off everything from cancer and liver disease to impotence and obesity—are also unproven. According to the Natural Medicines Comprehensive Database, there is insufficient evidence to determine the effectiveness of goji berries for any medical condition. Moreover, goji may interact with blood thinners (such as warfarin) and other medications. And as with some other food imports from China, the FDA has issued import alerts on goji berries for having illegal pesticide residues.
There’s nothing magical about goji berries—or “Tibetan” goji berries, in particular. They are healthful, but not the “healthiest food source on the planet.” All berries, including blueberries, are nutritious and high in antioxidants. Go for goji if you like it and can afford it, not in hopes that it will prevent or cure any disease. There’s no evidence to support the use of goji capsules.
Nearly as inflated as the health claims is the price of goji juice ($20 to $35 for 32 ounces), which is often sold through multi-level marketing programs. The dried berries are about $1.50 an ounce; fresh berries are rarely available here.

There’s a huge market for waters with additives: vitamins, minerals, herbs such as ginseng and ginkgo, flavorings, mint, aloe, fiber, green tea, caffeine, and more. On market shelves and in many vending machines, you’ll find products such as Vitamin Water, Dasani Plus, SmartWater, Propel Fitness Water, SoBe Lifewater, and Snapple Antioxidant Water. These waters are usually not as sugary as a regular soft drinks—though some, like most VitaminWater products, do contain as much added sugar. The vitamins and minerals in them are certainly not going to make you healthy, boost immunity or energy, or relax you, despite the claims. ConsumerLab.com recently found that one vitamin water had 15 times as much folic acid as claimed—1, 500 micrograms, a potentially risky level for some people if they drink it regularly (see Wellness Letter, September 2009). On the other hand, unless you drink the water with food, you cannot absorb much of the added vitamin E, D, A, or K, since these need some fat to be absorbed. You do not need the herbs and other substances in these products. Read the rest of this entry »
