Bioavailability refers to the proportion of a nutrient or compound in food that is absorbed and utilized by the body. Some foods have nutrients that are less bioavailable, which means that they are less easily absorbed and utilized by the body.

Here are some ways to increase the bioavailability of nutrients in your food:

1. Pair with vitamin C: Vitamin C can enhance the absorption of certain nutrients, such as iron and plant-based sources of iron. Therefore, pairing iron-rich foods, such as spinach or lentils, with foods high in vitamin C, such as citrus fruits or peppers, can increase their bioavailability.

2. Cook or process: Some foods contain compounds that can interfere with the absorption of nutrients. For example, raw spinach contains oxalic acid, which can bind to calcium and prevent its absorption. Cooking or processing spinach can reduce the oxalic acid content and increase the bioavailability of the calcium.

3. Add healthy fats: Some nutrients, such as fat-soluble vitamins (A, D, E, K), require the presence of healthy fats for optimal absorption. Therefore, adding a healthy fat source, such as avocado or nuts, to a nutrient-rich food can increase its bioavailability.

4. Ferment: Fermentation is a process that can increase the bioavailability of nutrients in certain foods. For example, fermenting grains can increase the availability of certain minerals, such as iron and zinc.

5. Soak or sprout: Soaking or sprouting grains, nuts, and seeds can increase their bioavailability by reducing the phytic acid content, which can interfere with the absorption of certain minerals.

Incorporating these strategies into your diet can help increase the bioavailability of nutrients in your food and maximize their health benefits.
