Kumquats are a high-fiber, healthful fruit that diabetics may enjoy during the winter. If you have diabetes or pre-diabetes, you are most likely focused on increasing your intake of fruits and vegetables. Eating more of these foods can help reduce your risk of developing heart disease, stroke, obesity, and other diseases associated with increased risk of individuals with diabetes. Fruits and vegetables contain many nutrients that have been shown to play a role in reducing your risk of developing diabetes or preventing diabetes symptoms from appearing. These include potassium, fiber, folate, vitamin C, and antioxidants. People with diabetes should eat at least 2½ cups (about 6 ounces) of fruit and 9½ cups (about 2 pounds) of vegetables every day. This is important because research shows that those who eat more fruits and vegetables have lower rates of diabetes than those who don't eat enough of these foods. Kumquats are one of several fruits that can be enjoyed by those with diabetes. Other examples include apples, pears, oranges, grapes, beans, peas, potatoes, carrots, tomatoes, and onions. Different fruits offer different benefits because they contain different amounts of vitamins, minerals, and antioxidants.
