A large-scale survey conducted by a research group at Iwate Medical University and others on the dietary habits of people affected by the Great East Japan Earthquake found that men who ate seafood more frequently had a lower risk of becoming obese.

The research group points out the importance of including fish and shellfish rich in nutrients that help burn fat in post-disaster diets.

A research group formed by Iwate Medical University and the Institute of Biomedical Innovation, Health and Nutrition conducted a follow-up survey of 10,000 people in four municipalities, including Rikuzentakata City and Otsuchi Town, in Iwate Prefecture, which were severely damaged by the Great East Japan Earthquake. Results were analyzed for the relationship between health and lifestyle of 4410 of them.

As a result, 296 new people became obese in the two years since the earthquake, but when we statistically analyzed the relationship with seafood intake, those who ate three meals of seafood did not eat it at all. They found that they had a lower risk of becoming obese than those who did not.

The more frequent fish meals, the lower the risk.

This tendency was seen only in men, and was particularly affected by those living in temporary housing.

It seems that if a large-scale disaster occurs and evacuation life is prolonged, the diet will be centered on carbohydrates such as rice balls, and the lack of exercise due to changes in the environment will be affected.

It is thought that this is because seafood is rich in taurine, DHA, and EPA, which work to burn fat.

Expert "Stockpile in consideration of balance"

Yoshiyo Kasaoka, head of the International Disaster Nutrition Laboratory at the National Institute of Biomedical Innovation, Health and Nutrition, said, ``The reason why men tend to be obese is because the percentage of obesity is higher than that of women in normal times. I don't think it's effective." He added, "As a countermeasure against large-scale disasters, it's important to be prepared so that you can have a balanced diet that is close to your normal diet, so it's important to prepare at home, at work, and in the local government. I want people to think about what to stockpile and what to eat after a disaster."
