"Review article: safe amounts of gluten for patients with wheat allergy or coeliac disease". Aliment Pharmacol Ther. 23 (5): 559–75. doi:10.1111/j.1365-2036.2006.02768.x. PMID 16480395. For both wheat allergy and coeliac disease the dietary avoidance of wheat and other gluten-containing cereals is the only effective treatment.
When it comes to condiments, mustard is about as healthy and low cal as it gets, and the pungent yellow stuff that contains about 5 calories per teaspoon has also been found to stimulate weight loss. Scientists at England’s Oxford Polytechnic Institute found that eating just one teaspoon of mustard can boost the metabolism by up to 25 percent for several hours after it’s been consumed. Researchers attribute this to capsaicin and allyl isothiocyanates, phytochemicals that give the mustard its characteristic flavor. So instead of reaching for the sickeningly sweet ketchup, make sure you have mustard on hand at your next BBQ.
If you're trying to shed pounds, consider this the ultimate guide to what you should be putting on your plate and the foods you should always keep in your kitchen. These good-for-you foods contain powerful nutrients and antioxidants that have been shown to help your body lose weight, feel full for longer periods of time, and have more energy. As a bonus, many have added benefits, too, such as preventing various diseases or reversing the signs of aging.
Speaking of things you find in the sea, oysters have also been shown to contribute to weight loss thanks to their impressive zinc content. One study found that obese people who consumed 30 milligrams of zinc per day—the equivalent of just six raw oysters—had lower BMIs, weighed less, and showed improvements in blood cholesterol levels. If oysters aren’t your thing, spinach, pumpkin seeds, and mushrooms are also excellent sources of zinc.
Coconut oil may be high in saturated fat, but that doesn’t mean you should write it off completely, especially when it comes to weight loss. In fact, a study of 30 men published in Pharmacology found that just two tablespoons per day reduced waist circumference by an average of 1.1 inches over the course of a month. What’s more? At roughly 117 calories per tablespoon, coconut oil (which has a versatile high smoke point) is an ideal cooking companion so long as you don’t use it every day and rotate in other cooking oils such as heart-healthy EVOO.
These support bone health and have other possible benefits. Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
