French fries and other fried foods are linked to an increased risk of anxiety and depression

Presse Santé

Eating fried foods, especially fried potatoes like French fries, can increase the risk of depression and anxiety, a study has found.

Researchers have studied the effects of fried foods on depression and anxiety. They found that regular consumption of fried foods is linked to higher levels of depression and anxiety in people. More studies are needed to understand the mechanisms underlying these effects. Depression and anxiety are the most common mental disorders in the world.

Fried foods are an important part of the Western diet and their consumption is increasing worldwide. Previous studies have shown that consumption of fried or processed foods, sugary products and alcohol are linked to a higher risk of depression and anxiety. Research also shows that the frying process can change the nutritional composition of foods and produce harmful chemicals. Fried carbohydrates such as potatoes, for example, generate acrylamide, which has been linked to obesity, metabolic syndrome and neurological disorders.

So far, few studies have looked at how acrylamide can affect anxiety and depression. Further research on this link can inform public health policy and dietary interventions for mental health disorders. Recently, researchers have studied the link between the consumption of fried foods and depression and anxiety. They found that eating fried foods, especially fried potatoes, was linked to an increased risk of anxiety and depression. They also found that acrylamide plays an important role in the development of anxiety and depression in adult zebrafish. The study was published in the journal PNAS.

Analysis of the effect of fried foods

To start with, the researchers analyzed data from 140,728 people from the UK biobank. The data included fried food consumption and incidence of anxiety and depression over a total follow-up period of 11.3 years. At the end of the study period, the researchers identified 8,294 cases of anxiety and 12,735 cases of depression. Overall, they found that people who eat more than one fried food per day have a 12% higher risk of anxiety and a 7% higher risk of depression than non-consumers. Frequent consumers of fried foods are usually male, young, and smokers.

The researchers then investigated possible mechanisms of the link between fried foods and depression and anxiety. To do this, they observed how chronic acrylamide exposure affects zebrafish over time. They found that exposing fish to low levels of acrylamide induced behavior similar to anxiety and depression. Further tests revealed that acrylamide reduces lipid production, causes neuroinflammation and damages the blood-brain barrier.

How fried foods are linked to depression and anxiety

Factors other than acrylamide may explain the effects of fried foods on brain health. For example, since the study did not establish a causal link, it may be that people who eat more fried foods have a higher risk of depression and anxiety or those who suffer from these conditions. . Alternatively, fried food consumption may be part of a bigger picture, i.e. whether people eat sweet sauces with fried foods or eat more fried foods while doing certain activities that may have other effects on the brain.

Study limitations

The main limitation of this study is that it was retrospective and did not control for many variables. In other words, many people are asked about the use of fried foods. People who eat too much tend to have more symptoms of anxiety and depression. In addition, they are also more likely to have less education, to have more obesity and medical problems, and to have lower income levels. Other variables may be driving higher levels of depression and anxiety, not just fried food consumption.

To really prove why, you’d have to take a large group of very similar people and give half of them more fried foods. Half of the group will eat more fried foods and the other half less. If anxiety and depression are more common among people who eat a lot of fried foods, the evidence is in.

Foods for better mental health

No specific foods have been proven to treat or prevent depression or anxiety. However, the Mediterranean diet, which includes the consumption of vegetables, fruits, beans and whole grains, is associated with lower levels of C-reactive protein than the “Western” diet. Since C-reactive protein is associated with inflammation, low levels of C-reactive protein may have a beneficial effect on the development of depression, anxiety, and other conditions affected by inflammation”, he added.

The effects

The implications of this research are that high levels of consumption of fried foods, especially potatoes, lead to increased levels of acrylamides in the blood. High levels of this toxin cause differences in the activity of nerve cells in the brain and [peuvent] cause depression and anxiety. The results are more pronounced in young people. The take home message is that the use of fried foods such as french fries, hash browns, bacon and the like should be limited to rare occasions. Regular use can lead to increased anxiety and depression, as well as many other health problems.
