Даже если вы соблюдаете сразу несколько ограничений, приложение поможет быстро отфильтровать неподходящие позиции. 5. Гликемический индекс Узнайте GI продукта буквально в пару касаний - Letti рассчитывает и визуализирует гликемический индекс на основании ингредиентов и показателей углеводов. Это особенно полезно тем, кто следит за уровнем сахара в крови или придерживается низкоуглеводных диет. 6.
