Can seafood and chocolate be eaten together?
Generally, it is not recommended to eat seafood and chocolate together. The detailed explanation is as follows:

Seafood such as shrimp, crab, and fish is rich in nutrients like protein, calcium, and iron. Chocolate, on the other hand, contains oxalic acid. When seafood and chocolate are consumed together, oxalic acid may combine with calcium from the seafood to form calcium oxalate. Calcium oxalate is a substance that the human body cannot easily absorb, which reduces calcium absorption and affects the body's uptake and utilization of calcium. Long-term consumption in this manner may lead to calcium deficiency. Therefore, it is not advisable to eat seafood and chocolate together.
Additionally, individuals who have allergies to seafood or chocolate should not consume them together. Allergies to seafood and chocolate are common types of food allergies, and consuming them inadvertently may trigger allergic reactions such as swelling, rashes, and difficulty breathing.
In daily diets, balanced intake of various foods and attention to food combinations are essential to better meet the body's nutritional needs and promote overall health.
