A great way to curb cravings, this simple jam contains much less sugar than the store-bought stuff. It takes about 3 minutes to prepare, and with the help of the almighty chia seed, it will fill you up quicker. Dollop on your morning oats, swirl into yoghurt, use as a fruit dip, or spread on some delicious rye bread. With the addition of liquid, chia seeds swell to 17 times their original size and slow the conversion of carbohydrates into sugar. Clever little things.
