When enjoying hot pot, not all vegetables and ingredients can be combined freely. Some traditional dietary beliefs suggest that certain food pairings may cause digestive discomfort or reduce nutritional value. Here's a closer look at some commonly mentioned combinations to avoid.

Tomatoes, Sweet Potatoes, and Potatoes with Seafood Hot Pot

Tomatoes and sweet potatoes are rich in vitamin C. According to a popular belief, they should not be eaten together with seafood.

The claim is that pentavalent arsenic compounds naturally present in some seafood may react with vitamin C and convert into arsenic trioxide (commonly known as arsenic), potentially causing poisoning.

Note: Modern scientific evidence does not support the idea that normal dietary combinations of seafood and vitamin C create dangerous levels of arsenic. However, this belief remains common in some traditional food cultures.

Beef Hot Pot and Malabar Spinach

Malabar spinach (Basella alba) is traditionally considered incompatible with beef hot pot.

According to folk wisdom, eating them together may lead to:

• Stomach discomfort
• Bloating and indigestion
• Constipation in more severe cases
