What can you eat on a day with nausea? How do you preserve energy? Which changes should you tell your oncologist about?
The answers depend on treatment, test results, weight and symptoms. Not a universal cancer diet.
Your plan considers treatment cycles and what you tolerate, day by day.

Treatment, antibiotics and diet can change the microbiome. We analyse it in your medical context to inform food and habit recommendations adapted to digestive tolerance.
We look at microbiome composition and estimated functions alongside your lab results.
We suggest meals and habits that support nutrition and digestive comfort during treatment.
Discuss any supplement or probiotic with your oncologist, especially when immunity is low.
