Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
While we’re on the subject of water, why not throw a few lemon slices into the hydrating and satiating beverage? In addition to adding a pop of color and flavor to a tall glass of H2O, lemon can also help encourage weight loss. Just one of the bright citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of a stress hormone called cortisol that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain.
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.
