In addition to dietary recommendations for the general population, there are many specific diets that have primarily been developed to promote better health in specific population groups, such as people with high blood pressure (as in low sodium diets or the more specific DASH diet), or people who are overweight or obese (in weight control diets). However, some of them may have more or less evidence for beneficial effects in normal people as well.
Good news, wine drinkers. Thanks to resveratrol, an antioxidant found in grape skin, drinking red wine in moderation can be part of a healthy diet. Some studies suggest that people who drink wine have smaller waists and less abdominal fat than those who drink mainly liquor. And having one glass of red wine can increase your body's calorie burn for up to 90 minutes afterwards. The antioxidants in wine might even help your body prevent cancer and improve heart health. Just be sure to stick to no more than a glass a day—the calories can add up fast.
Fresh, Frozen, or Canned Vegetables ― try something new. You may find that you love grilled vegetables or steamed vegetables with an herb you haven’t tried like rosemary. You can sauté (panfry) vegetables in a non-stick pan with a small amount of cooking spray. Or try frozen or canned vegetables for a quick side dish—just microwave and serve. When trying canned vegetables, look for vegetables without added salt, butter, or cream sauces. Commit to going to the produce department and trying a new vegetable each week.
Think smaller portions. Serving sizes have ballooned recently. When dining out, choose a starter instead of an entree, split a dish with a friend, and don’t order supersized anything. At home, visual cues can help with portion sizes. Your serving of meat, fish, or chicken should be the size of a deck of cards and half a cup of mashed potato, rice, or pasta is about the size of a traditional light bulb. By serving your meals on smaller plates or in bowls, you can trick your brain into thinking it’s a larger portion. If you don’t feel satisfied at the end of a meal, add more leafy greens or round off the meal with fruit.
A squeeze of lemon adds instant freshness to everything from drinks to salads to fish without additional calories, making it an ideal way to flavor food if you're watching your weight. Plus, the pectin fiber in lemons can help fill you up and fight off hunger cravings. And while it hasn't been scientifically proven, some experts believe that the citrus fruit can aid in weight loss, as well.
For a 2,000-calorie daily diet, aim for 2½ cups of vegetables and 2 cups of fruit a day. If you consume more calories, aim for more produce; if you consume fewer calories, you can eat less. Include green, orange, red, blue/purple, and yellow vegetables and fruits. In addition to the fiber, the nutrients and phytochemicals in these foods may help protect against certain types of cancer and other diseases. Legumes, rich in fiber, can count as vegetables (though they have more calories than most vegetables). For more fiber, choose whole fruits over juice.
