Pumpkin Tomato Cashew Soup
traditionally used to support healthy blood sugar balance
Why people make this soup
In traditional Chinese food therapy, pumpkin has long been prized for supporting the body’s natural metabolic balance, while tomato provides a wealth of vitamins and antioxidants thought to protect blood vessels. Cashews round out this trio with healthy fats and trace minerals. Together they make a soup that is sweet, mild, and nourishing — something Bro Niu reaches for whenever he wants something warming for the whole table that is also genuinely good for anyone with an eye on their blood sugar.
Bro Niu first put together this combination as a way to make a familiar pumpkin soup feel more substantial and more interesting. The cashews add a gentle richness; the dried tangerine peel and ginger keep the digestion comfortable and help reduce any sweetness that might otherwise feel cloying.
Who it suits / who should be cautious
- Suitable for the whole family, including children and older adults
- Particularly considered beneficial for people with elevated blood sugar or those supporting cardiovascular health
- Those with nut allergies should omit the cashews; lentils or black-eyed peas work well as substitutes
- People with diabetes should be mindful that pumpkin and tomato still contain natural sugars — portion sizes matter
Why these ingredients (the food-therapy logic)
- Pumpkin (nan gua): Contains the trace element cobalt, which is traditionally associated with supporting insulin function; mild, sweet, and easy on the digestive system
- Tomato (fan qie): Rich in vitamins P and PP (niacin and rutin), traditionally considered supportive of blood vessel integrity and healthy circulation
- Cashews (yao guo): A source of vitamins B and E and various trace minerals; in food therapy, associated with helping the body manage oxidative stress and supporting metabolic balance
- Dried tangerine peel (chen pi): A digestive classic — helps move qi, reduces bloating, and balances the sweetness of the pumpkin
- Fresh ginger (sheng jiang): Warms the stomach and aids absorption
Ingredients (4–5 bowls)
| Ingredient | Amount | Notes |

Method
- Peel the pumpkin, remove the seeds and fibrous centre, and cut into large chunks.
- Cut the tomatoes into quarters or rough chunks.
- Rinse the cashews and soak in cold water for 10–15 minutes, then drain.
- Soak the dried tangerine peel briefly until pliable; scrape off the white pith if desired.
- Place all ingredients in a pot with 8 bowls of water.
- Bring to a boil over high heat, then reduce to a gentle simmer and cook for about 1 hour, until the liquid reduces to roughly 4–5 bowls.
- Serve the broth along with the soup solids — everything is edible and nourishing.
Bro Niu’s tips
This soup is naturally sweet and mild. You can add lean pork (about 150 g) to make it heartier. If you can find frog legs (田鸡腿), adding them is said in traditional food therapy to help address skin discoloration such as brown patches — but the soup is delicious without them too. If you don’t have cashews, Bro Niu suggests substituting black-eyed peas or yellow soybeans. You can also add corn on the cob or carrots to boost sweetness and nutrition.
Community questions answered (selected)
-
Q (Mil): Can I add carrots to this soup? And do the cashews need to be prepared in any special way before adding them? Bro Niu: Yes, carrots work well in this soup. For the cashews, just soak and rinse them — that’s all you need before adding them to the pot.
-
Q (stephanie): Do the cashews need to be toasted first? If so, how? Bro Niu: If you want to toast them for a nuttier flavour, first simmer the cashews in water for 10 minutes and drain, then dry-toast them in a wok (no oil) until golden. If you skip the initial simmering, the outside will scorch before the inside is properly toasted.
-
Q (reader): Can I use this soup for a child with a runny nose? Bro Niu: This soup is suitable for healthy children. It is not specifically targeted at colds, but it is mild and nourishing enough for the whole family.
