There is no definitive answer to whether milk is good for schizophrenia. While milk is a good source of calcium and other nutrients that are important for overall health, there is little evidence to suggest that it has any specific benefits for people with schizophrenia.
In fact, some studies have suggested that milk may actually be harmful for people with schizophrenia. For example, a 2014 study published in the journal Schizophrenia Research found that higher levels of milk consumption were associated with an increased risk of developing schizophrenia in women.
It is important to note, however, that this is just one study and more research is needed to determine whether there is a causal relationship between milk consumption and schizophrenia.
Overall, if you have schizophrenia, it is best to follow a balanced and nutritious diet that includes a variety of foods, including dairy products such as milk, as well as fruits, vegetables, whole grains, and lean protein sources. It is also important to talk to your healthcare provider about any dietary concerns or questions you may have.
