These are normalized mass rates, ie grams per gram of plant mass. However, the mass yield per acre of cabbage has radically increased over that time period. Is it possible that a cabbage plant is capable of absorbing an absolute amount of minerals, and this is simply being diluted by ever-larger cabbages?
- carry_bit 7y agoThe explanation I've heard is that the total mineral content is about the same, but plants are producing more carbohydrates now due to an increase in atmospheric CO2, diluting the minerals. Consequently, if humans eat according the amount of minerals in the food, the increase in carbohydrates could also explain the increase in obesity.
- jkeuhlen 7y agoI don't think the lack of minerals in food explains obesity issues. In fact, I'm pretty sure we know what causes obesity. Significantly lower levels of activity and increased sugar consumption are two of the main culprits.
