Six myths about physical activities

1. Myth: Iced drinks can not be ingested after exercise in the heat.

Truth: The opposite is true. Iced liquids are absorbed much faster than hot liquids, thus reducing the chances of dehydration.

2. Myth: Exercise increases appetite, so I do not lose weight.

Truth: Research suggests that moderate physical activity decreases the urge to eat and does not increase it.

3. Myth: To lose weight one must control the calories.

Truth: The caloric value of the food we eat and the activities we do vary greatly for the calorie count to be effective. The balanced variety in food selection and exercise are the key to weight control.

4. Myth: Protein is the most important source for people who exercise and exercise.

Truth: The main priority of the body is the requirement for energy. Protein only works as a source of energy when there is insufficient fat and carbohydrate.

5. Myth: Athletes in training need extra protein.

Truth: Intense training, pregnancy, and growing teens require extra protein, but these amounts can be easily acquired through a correct selection of foods that contain protein. No scientific study has shown evidence that protein supplementation is necessary or effective.

6. Myth: Too much carbohydrate is bad.

Truth: Every source of energy is bad if ingested in excess. Carbohydrates such as cereals, fruits and vegetables are critical nutrients for the body and mind and make up 60 to 70 percent of your daily energy intake. They are the most efficient fuels and frequently include other compounds of great biological value, such as fibers and fructose.
