This is what happens in the brain when you eat junk food

Many nutrition experts say junk food contains harmful substances that can reduce brain function and cause dementia. Quoting from Koran Tempo, Fransiska Zakaria, a nutritionist from the Bogor Agricultural Institute, explained that junk food contains a lot of carbohydrates and fats.

"Even though the body also needs various nutrients, vitamins, protein, fiber and minerals," he said .

Fransiska suggests consuming junk food up to 10 percent of the total food intake in a day.

Prof. Cherbuin, chair of the NeuroMaging and Brain Lab (NIMBL) research, in an article entitled How Fast Food Causes Irreversible Brain Decline found strong evidence that unhealthy dietary habits and lack of exercise over a long period of time cause humans to develop type 2 diabetes and reduce function. brain like dementia and shrink the size of the brain.

High levels of sugar and fat from junk food can affect what happens in the human brain. In 5 Ways Junk Food Changes Your Brain, a neuroscientist and nutritionist at the School of Health and Biomedical Sciences, Reichelt, shares the results of research on what happens in the brain when you eat junk food.

1. Junk food is addictive

The brain has a reward system, a space in which processes start or stop action. This system also encourages us to decide whether to eat delicious food or not. The brain can be overwhelmed by junk food and make us eat more.

To control this food temptation, there is a prefrontal cortex that functions to regulate what we want.Australian researchers show that junk food contains more sugar and fat than natural foods. This can damage the hippocampus part of the brain, where people will feel hungry all the time.

2. Junk food reduces learning ability

The hippocampus as the memory center of the brain does not work well when eating a lot of junk food. In the brain, there are connections between elements of neurons that continue to develop in response to the environment in which we live. This process is called neuroplasticity. Junk food has the potential to reduce neuroplasticity which forms new memories and learns new things quickly.

3. Junk food reduces the generation of new neurons

The birth of new neurons or neurogeneris always occurs throughout life in the hippocampus. New neurons have high neuroplasticity, which means they are easily activated by environmental events and play an important role in forming new memories.

Lack of new neurons has been linked to mental health disorders including depression. Junk food can make us feel happy when we are sad, so eating more junk food makes us sadder.
