Characterized by the popular flavor of healthy sweet potato, new
SOYJOY Sweet Potato is a low GI food. The addition of papaya, raisins and orange affords a pleasing texture and tart accent, resulting in a delicious way to consume soy protein, dietary fiber and other nutrients that may be lacking in modern diets.

Against a background of growing health-consciousness triggered by increased opportunities for snacking, lack of exercise and other lifestyle changes, SOYJOY supports healthful between-meal consumption with the addition of a new item that expands the pleasure of choosing a favorite flavor.

Based on the corporate philosophy of 'Otsuka - people creating new products for better health worldwide,' Otsuka Pharmaceutical continues to contribute to the health and well being of people around the world.

  • About Low GI Foods

'GI' stands for 'glycemic index,' a measurement of how carbohydrates and sugars in foods affect blood sugar levels. A low GI indicates gradual absorption of carbohydrates, which is said to offer benefits for weight control. Foods with a glycemic index of 55 or less are considered low GI. All SOYJOY products are recognized as low GI foods.

  • About SOYJOY
