Human: My friend is a diabetic. What are the best foods for diabetics? Assistant: 
The best foods for diabetics are those that are high in fiber, low glycemic index, and nutrient-dense. Examples of such foods include fruits, vegetables, whole grains, nuts and seeds, legumes, and lean proteins. Eating these types of foods can help to stabilize blood sugar levels, as well as provide important vitamins, minerals, and antioxidants that may be lacking in a diabetic's diet. Additionally, it is important to consult with a healthcare professional to create an individualized meal plan tailored to your needs.
