Another essential component of a dengue recovery diet is whole grains. Whole grains are a good source of fibre, vitamins, minerals, and complex carbs. While fibre supports a healthy digestive tract, complex carbs give the body long-lasting energy. The body needs vitamins and minerals for optimum health and well-being. When recuperating from dengue, you can incorporate foods like brown rice, quinoa, oats, whole-wheat bread, and pasta into your diet.
