New research shows that blood sugar fluctuations have a significant impact on our mood and mental well-being.
These fluctuations, which affect hormone levels and the nervous system, are linked to the worsening of anxiety and depression, according to a report by Study Finds.
Mental health is influenced by a variety of social, psychological and biological factors. Among these, diet has emerged as a crucial biological factor, particularly due to its effects on depression and anxiety symptoms, especially in women.
“Antidepressants work for some patients but not for others,” said a family medicine resident with a doctorate in nutritional sciences, according to Study Finds. “Treatment strategies for mental illness should target every risk factor, including diet.”
Research has focused in particular on the Mediterranean diet, which is known for its low glycemic index. This diet includes plenty of vegetables, fruits, olive oil, whole grains, legumes and nuts, as well as moderate amounts of fish, meat and dairy products. The low glycemic index of the Mediterranean diet leads to lower blood sugar spikes, which can have a positive effect on mood.
The glycemic index ranks foods according to their potential to raise blood sugar levels. A diet containing high-glycemic index foods such as white rice, white bread, crackers and baked goods is associated with a higher risk of depression and anxiety.
Conversely, carbohydrates with a low glycemic index, such as parboiled rice and al dente pasta, are absorbed more slowly, resulting in a smaller rise in blood sugar and are associated with a lower risk of these mental health problems.
