A plant-based diet can provide essential micronutrients and healthy fats with careful planning. Key nutrients to consider include zinc, omega-3 fatty acids, vitamin D, and iodine, all of which play important roles in overall health.
Zinc and Immune Function
Zinc is crucial for immune function, wound healing, and DNA synthesis. Plant-based sources include beans, nuts, whole grains, and seeds.
| Food Source | Zinc Content (mg) per 100g |
| Pumpkin Seeds | 7.81 |
| Cashews | 5.78 |
| Lentils | 1.27 |
To enhance zinc absorption, pair these foods with sources of vitamin C, like citrus fruits or bell peppers. The body requires adequate zinc levels to maintain a robust immune response, making it vital for those on a plant-based diet to ensure sufficient intake.
Omega-3 Fatty Acids: ALA, EPA, and DHA
Omega-3 fatty acids encompass ALA, EPA, and DHA, which support heart and brain health. ALA is found in plant-based sources like walnuts, chia seeds, and flaxseeds.
| Food Source | ALA Content (g) per 100g |
| Chia Seeds | 17.8 |
| Walnuts | 9.08 |
| Flaxseeds | 22.8 |
The body can convert ALA into EPA and DHA, though this process is inefficient. Therefore, those following a plant-based diet might rely on algae-based supplements to directly obtain EPA and DHA, important for cognitive health.
Vitamin D and Iodine Considerations
Vitamin D is essential for bone health and immune function. While sunlight exposure can help synthesize vitamin D, many individuals may need dietary sources or supplements. Plant-based options include fortified plant milks and mushrooms exposed to UV light.
