Rheumatoid arthritis patients showed considerable improvement in morning stiffness and overall function in joints when potassium intake is at its optimal level.
In studies, such improvement comes through potassium’s role in reducing markers of inflammation and in healthy function in cells in joints.
Regulates Blood Sugar
Potassium’s influence on blood sugar control extends beyond essential mineral balance.
A 2014 study found that older adults with low dietary potassium had significantly reduced insulin sensitivity, a key factor in type 2 diabetes. This highlights how even one nutrient can have a major impact on metabolic health!(5)
More recent research from 2016 connected low serum potassium levels to elevated fasting glucose and increased diabetes risk.
The mineral is crucial in insulin secretion from pancreatic cells and helps muscles effectively utilize glucose.
This dual action makes potassium a key player in maintaining stable blood sugar levels and potentially reducing type 2 diabetes risk.
Lung Cancer Prevention
Recent medical breakthroughs in studies of cancer shed new information about potassium’s protective role in lung cancer.
In 2021, a thorough study discovered a sweet spot—reaching a desired 3,510 mg a day reduced lung cancer risk noticeably, but exceeding such intake failed to produce additional protection and could even cancel out its protective role.
How it works involves potassium’s role in regulating cell growth and healthy tissue function in lung tissue.
The study identified several key processes:
- Facilitates healthy cell division in lung tissue
- Maintains healthy use of oxygen
- Aid in detox processes
- Manages inflammatory processes in lung tissue
Scientists report such protection works best when potassium comes through foods, not supplements, and that supporting foods’ supporting nutrients have a supporting role in such protection.
The study re-emphasizes a key message: steady, balanced consumption of potassium through a healthy diet, not excessive consumption, is important.
