A study carried out by the editors of Environmental Nutrition reveals that this is not necessarily true. They purchased ten health food and ten grocery store snack items and compared them. They found similar amounts of iron, calcium, protein, vitamins and calories in the two groups. Despite similar nutritional values the natural snacks cost about 30 percent more. Foods proclaiming that they contain no cholesterol may contain saturated fats, also involved in heart disease.
Manufacturers sometimes list nutritional information for portions other than the package.
Still another study suggests an association between food allergy and joint pains. A study from Italy says that milk and cheese, artificial colors and preservatives, wheat and egg were common food allergens in their study group. They noted that symptoms may appear 12 hours after the intake of the offending food or 48 hours later. Continuous passive motion exercise tables are being recommended as an easy, yet effective form of exercise. The motorized tables move muscle groups through their range of motion without requiring effort on the part of the users.
