Insufficient potassium in the diet could result in fatigue, irritability, and high blood pressure. However, people with certain conditions are not advised to feed on food with high potassium.

On the other hand, however, consuming food with high potassium levels in significant amounts tends to impact the body negatively. We recommend consulting your nutritionists about the right amount.

An optimum amount of potassium in the diet is highly recommended. However, people with chronic kidney disease are advised to limit potassium intake in their diet.
