Fresh Purple Yam, Lotus Seed, Corn and Lean Pork Soup

Why people make this soup

For people watching their blood sugar, many sweet fruits need careful limiting — lower-sugar options like guava, papaya, pomelo, grapefruit, and kiwi are generally better suited. This hearty soup takes a different approach: instead of fruit, it brings together several ingredients — fresh yam, lotus seeds, corn, and goji berries — that Chinese food therapy traditionally associates with supporting the spleen, moderating energy metabolism, and nourishing the blood. The result is a naturally sweet, satisfying broth that the whole family can share.

Who it suits / who should be cautious

  • People seeking to support healthy blood sugar as part of a balanced diet, including those with or wishing to prevent type 2 diabetes
  • Suitable for the whole family, elderly and children included
  • Purple yam is nutritious; if unavailable, ordinary fresh white Chinese yam works equally well, or substitute with dried yam (~40 g / 1 liang)
  • Always consult your doctor or dietitian regarding overall dietary carbohydrate intake if you are managing diabetes

Why these ingredients (the food-therapy logic)

  • Fresh purple yam (zi huai shan): Chinese yam is one of the most prized spleen-nourishing foods in the tradition. The purple variety also contains anthocyanins, plant pigments with antioxidant properties. It is gentle on the digestive system and traditionally considered supportive for blood sugar balance.
  • Fresh lotus seeds (xian lian zi): With cores removed for this soup, lotus seeds tonify the spleen and calm the spirit, adding a pleasant, starchy texture.
  • Corn (su mi): Sweet corn is mild, lowers the glycaemic load compared with refined starch, and supports the stomach and spleen in the traditional framework.
  • Goji berries (gou qi zi): A well-known tonic berry, associated with nourishing the liver and kidneys, supporting healthy vision, and providing carotenoids and polysaccharides researched for metabolic benefits.

Method

  1. Peel the purple yam and cut into bite-sized chunks. Rinse well (wear gloves if your skin is sensitive to the mucilage).
  2. Rinse the fresh lotus seeds; remove and discard the bitter green core from each one.
  3. Rinse goji berries and soak for a few minutes.
  4. Strip corn husks and silk; cut each cob into three or four rounds.
  5. Blanch the lean pork in boiling water for 2–3 minutes, then rinse.

  7. Cook for about 1 hour 30 minutes until the liquid reduces to approximately 4 bowls.
  8. Serve with the soup and ingredients together; eating the solids adds to the nutritional benefit.

Bro Niu’s tips

Purple yam is not always available — regular fresh white Chinese yam (huai shan) works just as well for this soup. Dried yam (~40 g) can also be substituted. Even if purple yam is out of season, this soup remains a reliable, gentle staple for families looking to support digestive health and moderate blood sugar through diet.
