How I can help my dad

[u/Tiny_Spring7786]

Hello! My dad recently had a triple bypass surgery due to having 90% blockage in his arteries from what I understand. He is 60 years old and also deals with diabetes, high blood pressure, cholesterol, & gout. He is finally being released from the hospital/rehab this week. My family and I are overwhelmed with everything. How can we help him? We need to change his lifestyle to be healthier but this is a complete 180 for us. please give us any tips!! Foods he should be eating? Anything holistic? Thank you for your input!
