I know that this an old tread, I hope your husband is doing well, I will tell you about what I eat, once I was diagnosed with metastatic PC Gleason 9 I realized that meds alone was not sufficient, so I read everything I could get my hands on, studies done, video from PCC Prostate cancer center, and a lot of studies specifically the one done by the university of San Francisco, indicated that a diet based on whole food mainly plant based, lots of fruits and vegetables, low fat and high fiber was promising. So I went from Paleo to vegan overnight, and now I follow a semi a low fat vegan diet but I incorporate salmon once a week, you said breakfast was your husband issue, as for me was not what I liked or disliked it’s all about what do I have to do to get my health back, I’m 74 for now and my breakfast is simple, oatmeal not too much, 1 scoop of organic pea protein, 2 tablespoons of Sacha incha ( protein) 2 tablespoons of hemp seeds, 1 tablespoon of psyllium, 1/2 teaspoon of cinnamon, 1/2 teaspoon of 7 mushrooms powder, 2 tablespoons of nutritional yeast, 1 scoop of egg shell powder, 1 scoop of fermented beet powder a few walnuts and a hand full of blueberries I have this a 9am 2 hours after all my meds, I’m good until 1 or 2 pm.
Lunch is usually cooked veggies from the night before, quinoa salad (quinoa, tomatoes, onions olives) or cooked lentils with cashew cream, dinner veggies, could be any vegetable mix, mushrooms and quinoa or very little white rice cooked the night before and refrigerate so it becomes a resistant starch and beans normally black beans with two tablespoons of hemp seeds, im learning how too cook vegan Indian food, has lots of vegetables and quality proteins, I snack on high fiber fruits, nuts and hummus
I hope this helps, I will keep you and your husband in my prayers
