Golden rice : a transgenic variety being developed to address vitamin a deficiencies among poor. Calcium, potassium, sodium, magnesium, phosphorus, chloride, trace minerals. Essential fatty acids: only a few required. Fats are 3 long chain carbon molecules linked to a glycerol. Malnourishment: can cause deformities, disease, and death.
