We often avoid talking about food insecurity and suicide. These are tough topics, and not ones we usually discuss together. But when you look closer, they reveal a troubling picture of mental health in crisis. Around the world — and particularly in developing countries like Mexico — struggling to access enough nutritious food doesn't only affect physical health; it takes a real toll on mental well-being, too.
Recent research shows that more than 25% of adults in Mexico eat less because there simply isn't enough food available to them. Over 21% go hungry because they can't afford to eat. That isn't just a statistic — it's millions of people trying to survive, often in silence, and that silence itself feeds into deteriorating mental health: depression, anxiety, and, for some, thoughts of suicide.
There is growing evidence that hunger and mental health are deeply connected. This makes sense when you think about food as fuel not just for our bodies but for our minds. In many households, particularly across Latin America, men are traditionally expected to be the providers. When food runs short, the psychological pressure on them can be crushing. And while we tend to think of suicide as a deeply personal issue, it is also inescapably social — tied to conditions like poverty, stigma, and, yes, hunger.
In Mexico, research suggests that suicide remains a taboo subject. That makes it harder to discuss openly, let alone study rigorously. But data collected by the World Health Organization's Study on Global Aging and Adult Health (SAGE) offers us a rare glimpse. Even though only 318 people out of over 2,500 surveyed responded to questions about suicide, the findings were alarming: around 33% had thought about suicide, and 7% had attempted it.
What the data shows
Let's break it down. The more food insecurity people reported, the worse their mental health appeared to be. Those who ate less because there wasn't enough food were significantly more likely to show signs of depression and anxiety. And even after controlling for variables like age, gender, and education, one pattern stood out: being hungry regularly was associated with increased suicidal thoughts.
The study also looked at whether people could access fruits and vegetables — an indirect but important measure of food quality. Those who struggled to get nutritious food often had worse mental health outcomes. In short, it isn't just about whether you eat. It's about what you eat.
Not just a Mexico problem
It's easy to think of hunger as a problem that happens "somewhere else." But food insecurity is rising everywhere, even in high-income countries. In the United States, 14% of households were food insecure as of 2013, and since the pandemic the situation has only grown worse. Globally, nearly 815 million people are undernourished, and the stress that accompanies hunger continues to compound.
As with all research, this work has limitations. The data is self-reported, and in a culture where suicide is not openly discussed, some respondents may have chosen not to share their experiences. The study also doesn't include key variables like income or employment status, which would have given us a fuller picture. But even with these gaps, one thing is clear: the connection between hunger and mental health is real — and it is urgent.
What can we do? For a start, we need more research. But beyond that, we need policies that ensure people have consistent access to nutritious food. We also need to break the stigma around mental health and suicide, so that people feel safe enough to speak up and seek help. Because no one should have to choose between feeding their body and saving their mind.
