These tiny fish are the unsung stars of the sea. With 23 grams of protein per can and a truckload of omega-3 and omega-6 fatty acids, they're an easy way to load up on nutrients. They're also low in mercury and high in calcium, making them a smart fish pick for pregnant women. If the flavor doesn't appeal to you, soak them in milk for an hour to help cut down on the fishiness.
The weight of evidence strongly supports a theme of healthful eating while allowing for variations on that theme. A diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention and is consistent with the salient components of seemingly distinct dietary approaches. Efforts to improve public health through diet are forestalled not for want of knowledge about the optimal feeding of Homo sapiens but for distractions associated with exaggerated claims, and our failure to convert what we reliably know into what we routinely do. Knowledge in this case is not, as of yet, power; would that it were so.[21]
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.

Eating a healthy diet doesn’t have to be overly complicated. While some specific foods or nutrients have been shown to have a beneficial effect on mood, it’s your overall dietary pattern that is most important. The cornerstone of a healthy diet pattern should be to replace processed food with real food whenever possible. Eating food that is as close as possible to the way nature made it can make a huge difference to the way you think, look, and feel.

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.
