Zinc is an essential trace element required by your body in small quantities to ensure good health. If you have too much or too little of it in your body, it can result in several imbalances, such as the inability to maintain normal blood pressure.
Zinc and hypertension
At the renal level, the mechanism by which the kidneys excrete sodium via urine plays a key role in how your body controls blood pressure. There are many factors that may influence this excretion or retention of sodium by the kidneys. Some recent investigations have shown Zinc deficiency may play a crucial role in regulating the sodium transport channel in the kidneys and hence leading to hypertension. Many studies have also observed a link between Zinc deficiency and other chronic conditions such as Type 2 diabetes. There may also be an observable link between Zinc deficiency and an increased risk of developing hypertension in diabetic patients.
Recommendations on Zinc
An excess of zinc in the body or a deficiency may both affect your blood pressure adversely. So, it is necessary to modify your diet to balance the level of zinc in your body and consume appropriate portions of zinc-rich foods
There are many forms of Zinc supplements and the recommended daily dose of zinc in elemental form is 15 – 30 mg in adults with an upper limit of 40mg a day. However, the amount of zinc required may differ from person to person depending on their age, if they are pregnant, or if they have any other diseases. People with hypertension must always consult a doctor prior to taking zinc supplements.
You can add zinc-rich foods to your diet as a natural way to control hypertension. Pumpkin seeds, yoghurt, roasted cashews, shellfish, lentils and chickpeas, and dark chocolate are some of the foods that you can incorporate in your daily diet.
