Pizza, desserts, fast food, and soda are all foods that bring us comfort. We are so inclined to eat them that a diet high in fat, sugar, and processed foods has become known as a Western diet. We continue to binge on these foods despite the known links to obesity and other serious health risks, like diabetes. But did you know that this diet is also linked to cognitive impairment? A recently published paper reviewed the research on mouse models that link the Western diet to anxiety and learning/memory difficulties.
