The following is an excerpt from the website Upworthy about the potential for bananas fortified with Vitamin A.
Bananas are one of the world's staple crops. In West Africa, they're as important to the local diet as rice is to East Asia or potatoes were to the Irish. In parts of Uganda, the typical diet includes more than two pounds of bananas a day. But no single food has all the vitamins and minerals a person needs to live, and without a varied diet, you can get sick. For bananas and the people who depend on them, it's vitamin A that's the problem — there isn't enough in the fruit.
Not getting enough vitamin A is a big deal, especially for children. It can weaken the immune system and stunt growth, and it's the leading cause of preventable childhood blindness in the world. Of the preschool-age children who die every year in Africa, about 6% die of not getting enough vitamin A.
The obvious answer would be to eat a more varied diet, but fresh fruits and meat can be costly, and many low-income farmers don't have the money. But now scientists might have an easy way to add that oh-so-crucial vitamin into any banana they please.
Not all bananas lack vitamin A, but the ones they eat in Uganda do. You could try to crossbreed them with a vitamin-rich variety, but unfortunately, that wouldn't work. Domesticated bananas are sterile.
So scientists used genetic modification. Using genes from a vitamin-A-rich (but hard-to-grow) strain called Fe'i, QUT professor James Dale and his team loaded commercially viable banana seedlings with beta-carotene, a source of vitamin A.
