When taking Avana (Avanafil) 100 mg or any other medication, it's important to follow the specific guidelines provided by your doctor or pharmacist. Generally, Avanafil is taken 15-30 minutes before sexual activity, and its effectiveness can be influenced by food intake.
Here are some tips for taking Avanafil with a new diet:

1. Avoid high-fat meals: Fatty meals may slow down the absorption of Avana 100 mg, making it take longer to work. It's usually best to take it on an empty stomach or after a light meal.
   
2. Consistency: If your diet changes significantly (e.g., in terms of meal timing or contents), you might want to consult your healthcare provider to adjust how you take the medication.
   
3. Hydration: Drinking plenty of water is generally helpful, but avoid excessive alcohol, as it can interfere with the effectiveness of Avanafil and increase the risk of side effects.
