Dr. Siddle noted that seasonal depression can cause you to crave comfort foods that are high in carbohydrates, but eating a healthy, balanced diet is essential, even if you're limited to a dining hall and microwave. Vitamin D is especially crucial, she explained — in the Winter, the sun is sometimes too weak for your body to produce vitamin D on its own, and this important nutrient helps facilitate the release of neurotransmitters like serotonin, which regulate mood.
To make sure you're getting enough vitamin D in your diet, Dr. Seymour recommends "feel-good foods" like tuna, salmon, kale, and mushrooms, as well as products fortified with vitamin D, like milk and orange juice. Of course, before making any significant changes to your diet, both experts recommend talking to a doctor or dietitian.
