In today's episode, I stress the importance of ensuring that those following a plant-based diet receive all the necessary nutrients for their best health. While transitioning to a plant-based diet can offer numerous benefits, it's vital to be mindful of certain key nutrients.

A primary concern for many is vitamin B12. Since it's mainly found in animal products, those on a plant-based regimen may be at risk of deficiency. For this reason, I recommend incorporating a B12 supplement into your diet. A daily dosage of 500 to 1,000 micrograms of cyanocobalamin should suffice. Don't forget to monitor your B12 levels to ensure you're on track without going overboard.

When we talk about iron, it's essential to note that the type we get from plants differs from the heme iron in animal products. But don't worry! By pairing iron-rich foods like beans, lentils, tofu, spinach, and quinoa with vitamin C-rich foods (think citrus fruits), you can boost absorption.

Most people associate calcium with dairy, but plant-based eaters have a plethora of sources too. Consider fortified plant-based milks, almonds, tofu, and leafy greens like kale and collard greens. Remember, calcium plays a pivotal role in bone health.

A discussion on plant-based nutrition wouldn't be complete without touching on omega-3 fatty acids. These are crucial for heart and brain functions. While many associate these with fish, you can also find them in flax seeds, chia seeds, walnuts, and hemp seeds.

This episode aims to remind everyone of the importance of being conscientious about nutrient intake on a plant-based diet. With the right supplements and a diverse food selection, you can ensure you're well-nourished.

We'll also delve into the significance of vitamin D and iodine. Vitamin D is crucial, and while the sun does help, we can't solely rely on it. I often recommend fortified plant-based milk, fortified cereals, and supplements, especially during those cloudy days or if you're not getting enough sunlight. Aim to maintain vitamin D levels above 30mg per mL and always get checked to stay within a healthy range.

As for iodine, this mineral is essential for thyroid health. Iodized salt is a primary source, and if you use salt, half a teaspoon daily is usually enough. Alternatively, consider seaweed or iodine-rich supplements, but try not to exceed 150mg daily. For pregnant folks, aim for 220mg daily. I also want to emphasize that a 24-hour urine iodine test offers the most accurate measurement of iodine levels.

To wrap up, I want to highlight that while a plant-based diet can undoubtedly provide all the nutrients you need, even the most seasoned plant-based eaters might benefit from tailored advice. Stay informed, stay healthy, and enjoy the plant-based journey!
