Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Nutritional RecommendationsHi, are there any nutritional recommendations for cancer patients? As a caregiver, I am specifically looking into any protein powders to help my dad fight weight loss. Thank you.. ### Response: There are multiple factors that go into creating a nutritional plan, ranging from lab values such as kidney function, to muscle mass, desire to eat, ability to eat, etc. Id recommend speaking with a nutritionist as they are typically even more knowledgeable than physicians for nutritional advice. It should be covered under palliative/supportive care for the cancer. Youll want to consult them anyway depending on the state your dad is in physically as this point to ensure he doesnt have any nutritional deficiencies specific to the cancer he is fighting (e.g. GI cancers scan affect absorption of vitamins, minerals, fats, etc).Realistically if youre just looking for a caloric supplement, any of a number of protein drinks, such as ensure, will work. It will really come down to whether hes willing to drink them, find a flavor or brand he can tolerate and dont be afraid to switch it up for variety.
