Variety is the diet-planning principle calls for selecting foods from each of the food groups daily and varying your choices within each food group.
- A healthy diet requires balancing the quantity and quality of the food consumed. A healthy diet is made up of five essential components:
- Each vital vitamin must be present in an adequate diet, which also includes enough fiber and calories.
- When you ingest the right proportions of each nutrient, rather than one at the expense of another, you have a balanced diet.
- Calorie control is required to ensure that the energy you receive from the foods you eat and the energy you use during your day's activities are equal.
- Eating a variety of meals from each food group is important. You may ensure that you get all the nutrients required for a healthy diet by eating a diversified diet.
- Risk of taking too much of some nutrients and not enough of others is one of the main downsides of a repetitive diet.

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighbouring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.

P wave is the atria “firing”/depolarizing, the QRS complex is the ventricles depolarizing (and the atria are depolarizing while this happens), and the T wave is the ventricles depolarizing. Depolarizing is when it contracts, and repolarizing is when it relaxes and refills.
