 private ICollection<Type> foodTypes = new List<Type> { typeof(Vegetable), typeof(Fruit) };


// if (!foodTypes.Any(f => f.Name == food.GetType().Name))
            {
                string exceptionMessages = String.Format(ExceptionMessages.InvalidFoodException, this.GetType().Name, food.GetType().Name);
                throw new ArgumentException(exceptionMessages);
