SWAP: SPIRULINA FOR: BROCCOLI
“One hundred grams of spirulina contains 1000mg of calcium,
180mg of iron and 400mg of magnesium – but a serving of spirulina can be as low as 5g, so you won’t be getting those levels,” says nutritionist Zoe Bingley-Pullen. Conversely, it’s very easy to eat 100g of broccoli, which contains a comparable 47mg of calcium and 21mg of magnesium. It does contain less iron, but the cancer-fighting properties of broccoli are proven, whereas there’s no firm evidence for the nutritional claims of spirulina yet.
