25. Decrease the number of refined carbohydrates that you eat
The relationship between refined carbohydrates and water retention includes something that physiologists call a cascade. This cascade kicks off when a person has a meal that is rich in processed or refined carbohydrates. Once the body has broken these down, there is a spike in blood sugar levels and as such a spike in insulin levels. When insulin levels rise in the blood, the body responds by reabsorbing any sodium that might be present in the kidneys.
We already know that an increase in sodium means an increase in water retention which means that if you have a diet that is rich in refined carbohydrates, then you are probably going to suffer from water retention at some point or other. No one is saying that you must cut carbohydrates out altogether, but you should rather eat healthy carbs that include whole grains and such like.
