Blood Pressure and Diet

Diet plays an important role in the development of high blood pressure. It's equally important in helping to reduce high blood pressure. An unhealthy diet can promote the development of high blood pressure (hypertension). Conversely, it is possible to lower blood pressure through a tailored diet. Changing eating habits therefore plays an important role in treating high blood pressure. With a consistent, sustainable change in diet, it can be possible to avoid the need for medication or to reduce the dose required.

A higher intake of table salt, for example, can raise blood pressure. So it's wise to be careful with the salt shaker and to pay attention to the salt content of convenience products or ready-made meals. Often these products contain a lot of salt without the consumer noticing.

Another link between diet and blood pressure is overweight, which often results from poor eating habits. This is usually defined by the body mass index (BMI). BMI is the ratio of body weight to height. There are standard values that take age and sex into account. BMI can be misleading for certain groups for example, strength athletes with a lot of muscle mass may weigh more for their height.
A BMI above the normal range is often associated (see the previous caveat) with a higher risk of high blood pressure. Therefore, losing excess weight is a key part of treating hypertension. This is achieved in part through regular physical activity or exercise.

On the other hand, diet is a crucial factor. If you don't consistently and permanently change your diet, excess weight can't be reduced. So blood pressure and eating habits are closely linked. Below you will find more information on the topic of diet and high blood pressure. Among other things, you'll learn about salt, fructose, and beetroot in relation to high blood pressure.
