Swap plain noodles for this hearty variety (which you may find more easily by looking for soba noodles—just check that they're 100 percent buckwheat before purchasing). Buckwheat noodles contain fiber (12 grams per cup), and unlike most carbs, they contain protein, too, (24 grams per cup) making it more filling, aka harder to overeat than the regular stuff.

The latest Dietary Guidelines no longer give a daily cap for dietary cholesterol (previously it was 300 milligrams), because there’s abundant evidence that dietary cholesterol (found only in animal foods) has little if any effect on most people's blood cholesterol. Rather, saturated fats raise LDL (“bad”) cholesterol more than dietary cholesterol does. But don't go overboard with cholesterol-rich foods, since many of them are also high in saturated fats. And if you have cardiovascular disease or diabetes, ask your doctor if you should limit dietary cholesterol.

Blueberries are lousy with antioxidants, satiating fiber, potassium, and more, and according to researchers at the University of Michigan, the colorful fruits may also encourage weight loss. In a study of laboratory rats, scientists found that after 90 days the rats who consumed blueberry-enriched powder as 2 percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity, than the rats who didn’t consume any blueberry-enriched powder.
The next time you're craving some crunch, drop the potato chips and grab celery. The veggie is essentially all water and fiber — two things that fill you up quickly — and while one cup of chips can be upward of 160 calories, celery only contains about 14 calories per cup, chopped. Dip them in a serving of natural peanut butter (it's best if the ingredients list only has peanuts and salt on it) or hummus for a healthy snack.
Not to be outdone, oolong tea—a Chinese beverage—can help those who drink it shed up to a pound per week. According to a study in the Chinese Journal of Integrative Medicine, participants who regularly sipped oolong tea lost six pounds over the course of six weeks. What’s more? The tea’s antioxidants are thought to remove harmful free radicals and improve bone health.

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.
