This article will combine the hot discussions on the Internet in the past 10 days and use structured data to analyze the pros and cons of duck liver for you.
1. Comparison of nutritional value and potential risks of duck liver
| Nutritional information (per 100g) | Content | Recommended daily intake ratio |
|---|---|---|
| Vitamin A | 6500μg | 812% |
| iron element | 23mg | 128% |
| cholesterol | 400mg | 133% |
| protein | 20g | 40% |

2.Excessive cholesterol: A single intake of 100g of duck liver exceeds the daily upper limit of cholesterol and increases the risk of cardiovascular disease.
3.Heavy metal accumulation: Animal liver is a heavy metal filtering organ. Test data shows that the cadmium content in duck liver can reach 0.08mg/kg (the national standard limit is 0.2mg/kg).
4.Purine metabolism burden: Contains 300-400mg of purine per 100g, so gout patients should be particularly vigilant.
5.antibiotic residue: Irregularity in the breeding process may lead to drug residues, so it is crucial to choose formal channels.
3. Scientific food recommendations (based on the latest nutritional research)
| Crowd classification | Recommended serving size | frequency limit |
|---|---|---|
| healthy adults | 30-50g | ≤2 times per week |
| Pregnant women/children | 20-30g | ≤3 times per month |
| Three high people | ≤20g | ≤1 time per month |
