Does Cutting Out Meat Really Help Against Depression?

A new study suggests a possible connection between a meat-free diet and a lower risk of depression. However, experts caution against jumping to conclusions.

Can simply avoiding meat prevent depression?

A recent meta-analysis reviewed 20 studies and found that people who completely avoid meat tend to experience fewer cases of depression. The authors suggest that a meat-free diet might offer some protective effect – but this has not been scientifically proven.

Nutrition expert warns against premature conclusions

Uwe Knop, a qualified nutrition scientist and author, considers such findings speculative. The reason: observational studies only show statistical associations – not causes. It remains unclear whether meat consumption promotes depression or if depressed individuals simply eat differently.

Correlation is not proof

Knop refers to the classic “chicken or egg” problem: it could also be that depressed people eat more meat for other reasons, such as lacking the energy for a balanced diet. Therefore, such studies have limited reliability and often lead to exaggerated media headlines.

Meat alone is not the issue

Knop is clear: mental health problems have many causes – from work stress to social environment. The idea that reducing meat intake alone can prevent depression is far too simplistic.
