How long after eating fish can you drink milk?

The question 'How long after eating fish can you drink milk?' will be addressed from three perspectives: a scientist, a doctor, and a dietitian.


From a scientific perspective, there is no established chemical or physiological interaction between fish and milk that would necessitate waiting a specific amount of time before consuming one after the other. The human digestive system is well-equipped to handle a variety of foods eaten in close succession.

Key Points:

  • Digestive Process: The stomach and intestines break down food through enzymes and acids, capable of simultaneously handling fish (protein-rich) and milk (containing lactose and proteins).
  • Nutritional Interaction: There is no scientific evidence to suggest that the nutrients in fish and milk negatively interact in a way that would impact health.
  • Allergies and Sensitivities: Individual allergies or lactose intolerance may dictate personal dietary choices, but these are specific to the individual, not a general rule.


As a medical professional, I would advise that there is no medical reason to wait between eating fish and drinking milk. This notion is more of a cultural or mythological belief rather than one based on medical science. However, individual tolerances should be considered.

Key Points:

  • General Health: For most people, consuming fish and milk together, or one after the other, poses no health risks.
  • Allergic Reactions: If a person has a history of food allergies, particularly to either fish or dairy, they should avoid those allergens.
  • Digestive Comfort: Some individuals might experience indigestion or discomfort due to personal sensitivities, but this is not a universal reaction.


From a nutritional standpoint, both fish and milk are beneficial and can be part of a balanced diet. There is no dietary requirement to wait between consuming these two. In fact, they can complement each other nutritionally.

Key Points:

  • Balanced Diet: Fish provides high-quality protein and omega-3 fatty acids, while milk is a good source of calcium and vitamin D.
  • Food Combinations: The body can process multiple food types at once, and there's no evidence that eating fish and drinking milk together is harmful.
  • Personal Preference: If someone finds that this combination doesn’t suit their digestive system, they might choose to space them out, but this is based on personal preference and not nutritional science.


There is no required waiting period between eating fish and drinking milk. This belief is not supported by scientific evidence, medical knowledge, or nutritional science. Individual preferences and tolerances may vary, but no general health risks are associated with consuming these two foods together or in close succession.
