I met with Chia seeds, and studied their properties and decided to use in your diet. In combination with liquid, the seeds form a special gel that coats the stomach wall. This viscous mass that slows the absorption of carbohydrates. You can use any juice for this cocktail. There are contraindications: lemon juice should not be consumed for those who suffer from acute or chronic pancreatitis, inflammatory bowel disease, gastric ulcer and duodenal ulcer.
