Researchers at University College London published findings that eating processed, fatty food increases the risk of depression.
One group in the study of 3,486 people ate whole foods (mostly fresh vegetables, fruits, and fish) and the other ate fried food, processed meat, dairy, and desserts. Researchers controlled for factors like exercise and smoking, and even so, they found those with a processed diet had a 58 percent higher rate of depression.
Findings were published in the British Journal of Psychiatry.
Why? The study doesn’t know, so this is me making educated guesses. A clogged digestive tract (eating a low-fiber diet) leads to lower energy, which leads to an inability to complete tasks and discouragement.
Sugar and other processed food taxes and burns out the adrenals needed for stable mood.
Lack of micronutrients starves cells all the way to organs (brain, blood, bone, and more).
As blood pressure, constipation, energy depletion, enzyme depletion, weight creep, and hundreds of other issues compound, depression seems an almost inevitable result.
