Wild rice is not actually related to rice — it’s a seed of an aquatic grass. This nutrient-dense food is a great source of protein, fibre, magnesium and zinc. Wild rice is also high in protective antioxidants that help reduce the risk of many chronic diseases. Salmon is one of the richest food sources of omega-3 essential fatty acids EPA and DHA. These healthy fats are extremely important for optimal brain function, memory and mood. Eating a diet containing omega-3s will help lower your risk of depression and can improve mood.
