Practice life style changes...
value of 213mg/dl is marginal elevation. I would not be very concerned with this number. You should start a healthy life style. Cut down excess calorie food such as sweets, chocolates, deserts, sugar and so on. Increase fibre rich food such as whole grain, vegetables and some fruits. Reduce the fatty foods such as cheese, dairy products, deep fried food, meat, liver
and so on. With these dietary changes start exercise and other physical activities and maintain adequate body weight.
Needless to say, you should avoid alcohol and smoking
Hope this helps. Let me know if you need clarifications.
