High Blood Pressure

High blood pressure is another sign that you're not getting enough protein. Despite the fact that it is not a standard intervention, new research indicates that adequate protein consumption is critical for maintaining good blood pressure. For example, recent research examined data from 1,361 people over the course of 11 years. Surprisingly, this study found that eating a lot of protein was linked to decreased blood pressure.

Furthermore, people who consumed the most protein had a 40% lower chance of having high blood pressure. A meta-analysis of 40 randomized controlled studies also reveals that eating more protein "significantly lowers" blood pressure. The study's researchers went on to claim that eating extra protein "may be essential for the prevention of hypertension". In other words, not getting enough protein may lead to increased blood pressure levels.
