As a nutritious food, yam is deeply loved by people. However, when consuming yam, you need to pay attention to the combination with certain foods to avoid affecting health or reducing nutritional value. The following is a summary of the hot topics on the Internet in the past 10 days regarding foods that should not be eaten with yams and related scientific basis.
1. List of foods that should not be eaten with yam
| food name | Reasons not to eat together | possible reactions |
|---|---|---|
| cucumber | The vitamin C-degrading enzyme in cucumber destroys the vitamin C in yam | Reduce nutritional value |
| carrot | The ascorbate enzyme in carrots breaks down the vitamin C in yams | Nutrient loss |
| alkaline food | The activity of amylase in yam decreases in alkaline environment | Affect digestion and absorption |
| seafood | The tannic acid in yams combines with the protein in seafood | May cause indigestion |
| Pork liver | Vitamin C in yam will be oxidized by copper ions in pig liver | Nutrient loss |
2. Analysis of scientific basis
1.Vitamin C damage problem: Yams are rich in vitamin C, but when eaten with cucumbers and carrots, the enzymes in these foods will decompose vitamin C, leading to nutrient loss. Research shows that this damaging effect can reach more than 50% within 30 minutes of mixing.
2.Digestion and absorption effects: The amylase activity of yam will be significantly reduced in an alkaline environment with a pH value above 7.5. Experimental data shows that when eaten with alkaline foods, starch digestibility may decrease by 30%-40%.
3.protein reaction: The tannic acid content in yam is about 0.3%-0.5%. When eaten with high-protein foods such as seafood, it may form a complex that is not easy to digest. Clinical observations show that this combination may extend digestion time by 2-3 hours.
3. Best eating suggestions
| Recommended combination | nutritional value | Recommended serving size |
|---|---|---|
| red dates | Supplement blood and nourish skin | 200g yam + 5-8 red dates |
| wolfberry | Enhance immunity | 200g yam + 15g wolfberry |
| chicken | Protein complementation | 150g yam + 100g chicken |
| black fungus | Promote iron absorption | 150g yam + 50g black fungus |

1.Storage method: Uncut yam can be stored for 1 month at 10-15°C. Cut yam must be wrapped in plastic wrap and refrigerated and consumed within 3 days.
2.Peeling Tips: You can steam the yam for 2-3 minutes before peeling it to reduce skin itching caused by mucus.
3.cooking time: It is recommended to control the cooking time to 15-20 minutes. If it is too long, the nutrient loss rate will increase to more than 40%.
