Harvard psychiatrist explains why we crave junk food and solutions
- Dr. Uma Naidoo from Harvard Medical School explains that modern diets are filled with ultra-processed foods that stimulate pleasure centers in the brain.
- These foods, while providing short-term satisfaction, can lead to long-term health issues such as gut microbiome damage and increased anxiety.
- To mitigate cravings, healthier alternatives like whole fruits and drinking water are recommended.
A psychiatrist at Harvard Medical School, Dr. Uma Naidoo, discusses the modern craving for junk food, attributing it to the prevalence of ultra-processed foods that are high in sugar, salt, and unhealthy fats. Unlike our ancestors, who primarily consumed natural foods, today's diet is engineered to stimulate pleasure centers in the brain, leading to repeated consumption of items like ice cream and chips. This short-term satisfaction, however, comes at a cost. Over time, junk food can harm the gut microbiome, increase inflammation, and negatively impact mental health, contributing to lower mood and heightened anxiety. To combat these cravings, Dr. Naidoo suggests healthier alternatives, such as choosing whole fruits over processed juices, which provide more fiber and satiety. Additionally, she recommends drinking water when cravings arise, as it can trick the brain into feeling full. These strategies aim to help individuals make better dietary choices and reduce their dependence on unhealthy foods.
