Living next to a busy road may cause you serious heart problems, a new study suggests. The perils of air pollution are real and plentiful.

When most of us think of calories, we think of how fattening a food is. In dietary terms, calories are the amount of energy that a food provides. If we consistently take in more energy than we need, we will gain weight. If we take in too little energy, we will lose weight, fat, and eventually muscle mass. The definition of a calorie is the amount of energy needed to raise the temperature of 1 gram (g) of water through 1° Celsius.

According to the 2015-2020 Dietary Guidelines for Americans, women are likely to need between 1,600 and 2,400 calories
