Benefits of Cassava
Low salt diet
Cassava bread has no additional salt, so is good for people requiring a low salt diet. It can be eaten with complementary foods such as avocado or boiled crab where no salt is required. Cassava has nearly twice the calories than potatoes, perhaps one of the highest for any tropical starch rich tubers and roots. 100 g root provides 160 calories. Their calorie mainly comes from sucrose, forming the bulk in these tubers accounting for more than 69% of total sugars. Complex sugar amylose is another major carbohydrate source (16 17%).
