When evaluating which dried fruit contains the most copper, the answer depends on whether you're considering the absolute amount per a commonly specified serving size or the concentration of copper per ounce. Based on available data, dried figs provide the highest absolute amount of copper per specified serving (0.4 mg per cup), while dried pears and dried peaches offer the highest copper concentration per ounce (0.1 mg per ounce).
Understanding Copper Content in Dried Fruits
Copper is an essential trace mineral vital for numerous bodily functions, including energy production, iron metabolism, and maintaining healthy connective tissues. Dried fruits are often concentrated sources of this important nutrient. However, comparing their copper content requires careful attention to serving sizes.
Highest Copper Per Specified Serving
When looking at the amount of copper in a typical serving size as presented in nutritional data, dried figs stand out. A single cup of dried figs provides approximately 0.4 milligrams of copper, which accounts for 48% of the Daily Value (DV). This is the highest absolute amount listed among common dried fruit servings.
Highest Copper Concentration (Per Ounce)
To compare fruits on an equal footing, it's helpful to normalize their copper content to a standard unit, such as per ounce. When we adjust for serving size:
- Dried Pears: Offer 0.1 mg of copper per ounce, equating to 12% DV.
- Dried Peaches: Provide 0.1 mg of copper per ounce, contributing 11% DV.
- Dried Figs: Although a cup offers 0.4 mg, a cup is approximately 8 ounces. Therefore, dried figs contain roughly 0.05 mg of copper per ounce (0.4 mg / 8 oz).
- Dried Apricots: A cup of dried apricots contains 0.1 mg of copper. When normalized, this is approximately 0.0125 mg per ounce (0.1 mg / 8 oz).
Therefore, dried pears and dried peaches demonstrate the highest copper concentration per ounce.
Comparative Copper Content in Dried Fruits
Here's a summary of copper content in various dried fruits, illustrating the differences in serving sizes and their normalized per-ounce values:
| Dried Fruit | Serving Size | Copper (mg) | Copper (%DV) | Copper (mg/oz - approximate) |
|---|---|---|---|---|
| Dried Figs | 1 cup | 0.4 | 48% | 0.05 |
| Dried Pears | per oz | 0.1 | 12% | 0.1 |
| Dried Peaches | per oz | 0.1 | 11% | 0.1 |
| Dried Apricots | per cup | 0.1 | 11% | 0.0125 |
Note: Per-ounce calculations for cup-based servings assume 1 cup ≈ 8 ounces.
Why Copper is Essential for Health
Copper plays a crucial role in maintaining overall health. Its functions include:
- Energy Production: It's a key component of enzymes involved in cellular energy generation.
- Connective Tissue Formation: Copper is essential for the formation of collagen and elastin, which are vital for healthy skin, bones, and blood vessels.
- Iron Metabolism: It helps the body absorb iron and utilize it to form red blood cells, preventing anemia.
- Brain Health: Copper is important for neurotransmitter synthesis and nervous system function.
- Immune System Support: It contributes to the proper functioning of the immune system.

Incorporating High-Copper Dried Fruits into Your Diet
Adding copper-rich dried fruits to your diet can be both delicious and beneficial. Here are some practical tips:
- Snack Smart: Enjoy a small handful of dried figs, pears, or peaches as a nutritious snack on their own.
- Breakfast Booster: Chop them and add to oatmeal, yogurt, or cold cereals.
- Baking Ingredient: Incorporate them into muffins, bread, or energy bars for added flavor and nutrients.
- Salad Topping: Dice dried fruits and sprinkle over green salads or grain bowls for a touch of sweetness and chewiness.
- Trail Mix: Combine with nuts, seeds, and other dried fruits for a homemade, energy-boosting trail mix.
Always remember to consume dried fruits in moderation due to their concentrated sugar content. Consulting a registered dietitian or nutritionist can help you tailor your diet to meet your specific nutritional needs.
