Understanding which nuts serve as healthy staples versus hazardous indulgences requires comparing their raw nutritional parameters. The table below outlines key macronutrients and mineral dynamics across commonly offered tree nuts.
| Nut Variety | Dietary Fat Content (%) | Approx. Ca:P Ratio | Safety Assessment for Wildlife |
|---|---|---|---|
| Raw Pistachios | 45% | 1:3.5 (Heavily Inverted) | Treat only; high risk of MBD if fed often |
| Acorns (White Oak) | 5%, 10% | 1:1.2 (Near Balanced) | Natural staple; optimal wild nutrition |
| Hazelnuts / Filberts | 60% | 1:2.5 (Moderate Inversion) | Safe nuts for squirrels; natural winter fuel |
| Raw Peanuts (Legumes) | 49% | 1:5.8 (Severe Inversion) | Dangerous; trypsin inhibitors and aflatoxin hazard |
| In-Shell English Walnuts | 65% | 1:3.0 (Manageable) | Healthy supplement; excellent for dental wear |
