Hey guys, so my mom was diagnosed with diabetes last February. Her blood sugar is so high like it reached 381 mg/dl. It is very high and also dangerous. We did our best together with my sister to improve our mother's quality of life. We manage to make her blood sugar from 380+ to normal range with the help of some fruits and vegetables and also Prayer helps a lot.
I'm going to list down the foods that made her blood sugar back to normal range again. I hope this will help you too.
1. AVOCADO 
Avocado is low in carbohydrates and high in fiber. It is considered as one of the good source of monounsaturated fats or good fat. It doesn't easily increase blood sugar levels. Avocado by itself is great on sandwiches instead of mayo which is full of bad cholesterol. Guacamole is a very good example.
2. APPLE
An apple a day keeps the doctor away. Apple is rich in fiber and low in calories. It is also good to eat the skin of this fruit because apple skin is full of antioxidants which helps your body fight free radicals and can protect you from a number of diseases.
3. CITRUS FRUITS
Citrus Fruits are not just rich in Vitamin C; it is also consist of folate and potassium which helps to normalize blood pressure.
4. LETTUCE
Lettuce is a good source of alpha-lipoic acid, it is a micro-nutrient that strengthen the body against stress.
5. BROCCOLI & CAULIFLOWER
These two vegetables are both low in Glycemic Index. It means that it does not increase too much the blood sugar in the human body.
6. CUCUMBER
Contains zero calories and Glycemic Index. It contains hormones that our body cells needs to produce insulin that lowers the glucose level of the body.
7. EGGPLANT
Eggplant helps to prevent the escape of glucose-releasing enzymes by 60% so it controls the increase of blood sugar level.
So that's all I can share with you guys. Right now my mom's blood sugar range from 110-140 is the highest for two months now which is pretty normal. Just always remember that too much of everything is a bad as too little. Do it at your own risk. God Bless!
