Dairy foods are the primary dietary source of calcium but some are allergic to these while others are told to avoid consuming too much due to their high fat content. | Dairy foods are the primary dietary source of calcium but some are allergic to these while others are told to avoid consuming too much due to their high fat content. |
A gene has been altered in the carrot which allows the calcium within it to cross more easily over the plant membranes. | A gene has been altered in the carrot which allows the calcium within it to cross more easily over the plant membranes. |
On its own, the carrot would not meet the daily requirement of 1,000mg of calcium, but if other vegetables were similarly engineered, intake could be increased dramatically. | On its own, the carrot would not meet the daily requirement of 1,000mg of calcium, but if other vegetables were similarly engineered, intake could be increased dramatically. |

"There has been great resistance to genetic engineering, but gradually we are moving away from the spectre of 'Frankenstein food' and starting to appreciate the health benefits it may bring." | "There has been great resistance to genetic engineering, but gradually we are moving away from the spectre of 'Frankenstein food' and starting to appreciate the health benefits it may bring." |
