What dietary advice is important for patients on INH?

The correct choice focuses on ensuring sufficient vitamin B6 intake, which is crucial for patients undergoing treatment with isoniazid (INH). Isoniazid is a medication commonly used to treat tuberculosis, but it has a known side effect of interfering with the metabolism of vitamin B6 (pyridoxine) in the body. This interference can lead to a deficiency of this important vitamin, which is essential for various bodily functions, including the synthesis of neurotransmitters and the metabolism of amino acids.

Maintaining adequate levels of vitamin B6 helps to prevent symptoms such as peripheral neuropathy, which can occur due to the deficiency induced by INH. Therefore, dietary advice that emphasizes the importance of incorporating foods rich in vitamin B6, such as poultry, fish, potatoes, chickpeas, bananas, and fortified cereals, is important for patients on INH.

While the other options might connect with general dietary habits, they do not address the specific nutrient interaction that is significant for patients taking INH. Increasing carbohydrate intake, avoiding all dairy products, or reducing protein intake do not directly mitigate the side effects of INH or help counteract potential deficiencies in vitamins. Thus, focusing on adequate vitamin B6 intake is the most relevant and critical dietary
