Hello,
what is your opinion on the consumption of poppy seeds as a source of calcium in the case of milk protein intolerance... I have read in sources that its bioavailability is only about 10%, so even though the calcium content in poppy seeds is high, its bioavailability is low... I would also like to ask for your opinion on calcium-fortified plant-based drinks sourced from seaweed.

Poppy seeds are indeed one of the richest sources of calcium. However, their bioavailability is significantly reduced by the alkaloids (opiates) they contain. The proportion of these decreases with the increasing maturity of the poppy, so the often-cited 10% is relative. Moreover, heat treatment significantly reduces the amount of these alkaloids, so in industrially processed foods containing poppy seeds, you can expect a much higher value.

Seaweeds are a concentrated source of a wide range of minerals (not only calcium) and are increasingly used in the food industry. Given their nutritional benefits and versatility, they can be labeled as "superfoods," and we will encounter them more frequently in our diets in the future. The only potential "blemish" is the risk of contamination with heavy metals or petroleum industry derivatives, as a substantial part of the world's production is cultivated in farms that are part of open seas, and not every batch is monitored as regulations would suggest.

The bioavailability of minerals from seaweeds is very high, and seaweeds contain a minimal amount of antinutritional substances (primarily fiber). However, due to their attractiveness, they disproportionately increase the price of the product.
