Why Foods with Calcium Should Be Part of Your Diabetes Diet?

Due to several reasons, foods with calcium should be an important part of the diabetes diet chart:

  • As per research, calcium rich foods for diabetics offset the chances of osteoporosis, a condition that is strongly associated with diabetes. They also stop the progression of the disease in people who have been diagnosed with it. Calcium and vitamin D supplementation is also advantageous in optimising glucose metabolism. And this is important for people with diabetes.
  • Studies also put down that regular supplementation with vitamin D and calcium for a period of six months can help in improving insulin sensitivity in people with pre-diabetes.
  • Calcium for people with sugar is beneficial the other way round as well. The mineral can help people with pre-diabetes, the precursor to full-blown diabetes, and people with higher chances of pre-diabetes based on family history, ethnicity, lifestyle and diet.
  • Observational studies outline a clear connection between low calcium intake and vitamin D and the prevalence of metabolic syndrome and type 2 diabetes.
  • The advantages of calcium on the bone health of individuals with diabetes should also not be overlooked. People with type 1 or type 2 diabetes have an increased risk of suffering from osteoporosis. It is a condition caused due to bone fractures and low bone density. And studies show that diabetic individuals have higher chances of suffering from spine, hip and foot fractures than people without diabetes. This increased risk makes one of the most important reasons for people with diabetes to load up on their consumption of calcium-rich foods. Also know about prediabetes diet.
