I would advise your aunt to lower her sugar and carbohydrates intake, and to include whole grains in her meals instead of refined carbohydrates. She can choose wholemeal bread instead of white bread, and brown rice instead of white rice.
On top of controlling her carbohydrate intake, there are some common herbs which she can include in her diet to nourish her Yin. She can make herself soups using Kudzu Root or Chinese Yam 2-3 times a week. She can also consider replacing her carbohydrates in some meals with Chinese Yam as it is a low GI food.
She can also include astragalus and wolfberries in her soups as they can help to nourish Kidneys and Spleen. Other than soups, she can make herself tea with astragalus and wolfberries several times a week.
Place 2-3 pieces of astragalus and a teaspoon of wolfberries in a cup. Simmer these ingredients for 5-10 minutes and it is ready to drink. This helps to nourish Kidneys and Spleen and astragalus also has the effect of lowering blood sugar levels.
