Why Blood Sugar Management Matters

Maintaining stable blood sugar levels is essential for preventing a range of health complications. When blood sugar is consistently high (hyperglycemia), it can lead to:

Type 2 Diabetes: A chronic condition where the body doesn't use insulin properly or doesn't make enough insulin.
Heart Disease: High blood sugar can damage blood vessels and nerves, increasing the risk of cardiovascular issues.
Kidney Damage: Also known as nephropathy, this occurs when the kidneys are overworked trying to filter excess sugar from the blood.
Nerve Damage: Known as neuropathy, high blood sugar can damage nerves, leading to pain, numbness, and other issues, particularly in the hands and feet.
Eye Damage: High blood sugar can harm the blood vessels in the retina, leading to vision problems, including blindness.

By incorporating foods that help regulate blood sugar, you can proactively manage these risks and improve your overall well-being.

1. Leafy Green Vegetables: Spinach and Kale

Leafy green vegetables like spinach and kale are nutritional powerhouses, low in calories and high in fiber, vitamins, and minerals. They have a minimal impact on blood sugar levels and can even help improve insulin sensitivity.
