Hypertension is often experienced whenever someone has high blood pressure. To lower this down, there are some types of food which have the ability to decrease the high pressure over time. Such include :

Leafy greens - Vegetables have a high amount of potassium. They contain many nutrients that help get rid of sodium that causes high blood pressure.

Skim milk - Skim milk can contain a high amount of calcium. Skimmed milk does not have a lot of fat within it and it is an advantage to someone which has hypertension. 

And many more :)
