Living or dealing with depression can be challenging, as it hinders normal functioning in every aspect of life. A new study indicates that consuming high amounts of ultra-processed foods (UPFs)—particularly those with artificial sweeteners—may increase the risk of developing depression. The study, co-authored by researchers at Harvard T.H. Chan School of Public Health, found that participants who consumed nine or more servings per day of ultra processed foods had a 50 percent higher risk of developing depression. Artificial sweeteners were also linked to a 26 percent higher risk of depression. Additionally, ultra processed foods can lead to chronic inflammation, disruption of gut bacteria, rapid fluctuations in blood sugar, and contribute to overconsumption and binge eating, all of which can impact mood negatively.
Ultra processed foods are high in calories, palatable, and ready-to-eat, but they have little to no nutritional value. These foods lack essential vitamins, minerals, and antioxidants necessary for optimal brain function and mood regulation, and are often high in sugar and unhealthy fat content, which can lead to chronic inflammation and negatively impact neurotransmitter function and overall brain health. Furthermore, ultra processed foods and artificial sweeteners may disrupt the delicate balance of gut bacteria, causing inflammation and mood disturbances, and can also lead to rapid fluctuations in blood sugar levels, mood swings, and feelings of irritability and depression. A balanced and nutritious diet, rich in whole foods, fruits, vegetables, lean proteins, and healthy fats, is generally recommended for both physical and mental well-being.

Ultra processed foods may lead to depression, finds study – FAQ’s
What are ultra processed foods?
Ultra processed foods have a lot of additives and include fats, starches, added sugars and hydrogenated fats. These foods are high in calories, palatable and are ready-to-eat. The study also told that people who consume more unprocessed foods have a tendency towards having greater Body Mass Index, higher smoking rates, and have a high risk of catching diseases such as diabetes, hypertension and dyslipidemia, and also are physically less active.
Why consuming ultra processed foods or artificial sweeteners increase the risk of depression?
The relationship between diet and depression is complex and not fully understood. But there are several reasons why ultra-processed foods and artificial sweeteners may contribute to or exacerbate symptoms of depression.
1. Lack of essential nutrients
“Firstly, these foods tend to be nutritionally deficient, lacking essential vitamins, minerals, and antioxidants necessary for optimal brain function and mood regulation,” says Dr Nagabhirava.
2. High sugar and fat content
Secondly, the high sugar and unhealthy fat content of UPFs often leads to chronic inflammation. This has been linked to depressive symptoms by negatively impacting neurotransmitter function and overall brain health.
3. Gut bacteria equilibria
“Furthermore, the gut-brain connection, and both ultra-processed foods and artificial sweeteners may disrupt the delicate balance of gut bacteria, potentially causing inflammation and mood disturbances. These foods can also cause rapid fluctuations in blood sugar levels, leading to mood swings and feelings of irritability and depression,” shares Dr Nagabhirava.
4. Overconsumption and binge eating
Additionally, the convenience and palatability of ultra-processed foods can contribute to overconsumption, leading to feelings of guilt or dissatisfaction with one’s diet, which can, in turn, impact mood.
5. Improper diet and sedentary lifestyle
A diet high in ultra-processed foods and artificial sweeteners is often associated with other unhealthy lifestyle factors, such as a sedentary lifestyle and reduced intake of fruits and vegetables, which can independently contribute to depression.
6. Genetics and other factors
It is important to recognise that these dietary factors are just one piece of the complex puzzle of mental health, and individual responses can vary. It is important to emphasize that while there is evidence linking diet to mental health, including depression, other factors like genetics, life circumstances, and individual responses to food play a significant role.
