You know about the obvious science-backed reasons to avoid processed snacks, but be especially vigilant when you're feeling blue.
"For good mental and physical health, you need a balance between two fatty acids, omega-3s (from nuts, seeds, fish and other oily foods) and omega-6s (from cooking oils and grains like corn and soy). In nature they appear in balanced proportions. But processed foods, which come from grains and are often fried in oil derived from grains, are super-high in 6 and often very low in 3. And that's bad: A recent study from the University of South Carolina found that those with the highest intake of omega-6 fatty acids have twice the risk of becoming depressed. Since depression is closely linked to weight gain and high intakes of omega-6s, it's clear that high-calorie fried foods are the saddest foods in America."
