In winter, nourishing foods like root vegetables, leafy greens, and hearty grains are ideal. Warm soups with carrots, sweet potatoes, and pumpkin provide comfort and nutrients, while leafy greens like spinach and kale boost immunity. Whole grains like oats and quinoa keep you energized, and citrus fruits add vitamin C to combat colds. Don’t forget to eat nuts, seeds, and warm beverages.
