It is often said that fish is 'brain food' and there is good evidence that eating fish, which contains omega-3, is good for your health. There have been reports that it may reduce the risk of developing dementia, especially when it is eaten as part of a healthy diet. 

Omega-3 is a kind of fat found in cell membranes (the protective 'skin' that surrounds cells). It is made in our bodies, but we mostly get it from our diet. Oily fish have especially high levels of omega-3.

Omega-3 is important for our brain throughout life, from development in the womb to adulthood. It is thought to reduce inflammation and oxidative stress in the brain – both of which may contribute towards the development of Alzheimer's disease.

Some types of freshwater fish commonly found in Kalimantan and high in omega-3 content include snakehead fish (haruan/gabus) and betok fish. In addition, seawater fish such as mackerel and tuna are also known to be rich in omega-3 and are often found in Kalimantan markets.
