Excess sodium, found in many processed foods and restaurant meals, raises blood pressure in some people and can have other adverse effects. The Dietary Guidelines recommend a limit of 2,300 milligrams a day for the general population; people with hypertension or prehypertension can benefit from a further reduction to 1,500 milligrams per day. As you cut back on sodium, eat more potassium-rich foods, which help lower blood pressure. These include citrus fruits, bananas, beans, avocados, some fish, and dairy products.
Prefer water over other beverages. Avoid sugary drinks, and limit intake of juices and milk. Coffee, tea, artificially-sweetened drinks, 100-percent fruit juices, low-fat milk and alcohol can fit into a healthy diet but are best consumed in moderation. Sports drinks are recommended only for people who exercise more than an hour at a stretch to replace substances lost in sweat.

A 2012 CDC study found that the average adult consumes about 100 calories worth of alcohol daily, but favoring a glass of wine instead of beer or sugary cocktails can drastically reduce that figure and make your waistline slimmer. In addition to having fewer calories than most alcoholic beverages, red wine, in particular, is a good source of those waist-shrinking flavonoids that are also found in red fruits. Resveratrol, a particular flavonoid found in red wine, is believed to have heart health benefits because it helps prevent blood vessel damage and reduces your ‘bad cholesterol.’ Just remember to imbibe in moderation.
Here’s more reason to add avocado to everything. “Most of the carbohydrate content in avocados comes from fiber (1/3 of an avocado provides 11 percent of our daily fiber needs), and it also contains monounsaturated fat, which is known as a ‘good’ fat and [is] important for heart health,” says Zigler. Together, the healthy fats and fiber will keep you full to avoid mindless munching throughout the day.
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.
