Should we continue to force our blind, special needs son to follow a balanced diet he dislikes, fearing negative health consequences for his body in the future, or is letting him eat what he desires, knowing its harm, considered a sin that warrants divine punishment?

Imam Ahmad and Al-Tirmidhi narrated a hadith from Al-Miqdam bin Ma'dikarib that the Prophet (peace be upon him) said: "No human ever filled a vessel worse than the stomach. A few morsels are sufficient for the son of Adam to keep his back straight. But if he must eat, then one third for his food, one third for his drink, and one third for his breath." This hadith is a comprehensive principle of medicine, as overeating is the root of all ailments, and reducing it protects from diseases. Decreasing food intake has health benefits for the body and heart; it leads to tenderness of the heart, strength of understanding, humility of the soul, and weakening of desires and anger, contrary to abundant food intake which results in the opposite.

There is no harm in setting up a suitable dietary plan for the blind child, while taking care not to restrict him excessively, and applying it gradually, trying to convince him of its health and mental benefits. If its negative impact on his behavior and thinking is confirmed, it is better to abandon it.
