White pulp to Golden Yellow (such a visual feast!!), unripe to ripe mangoes are rich in nutrients that aid in normalizing body's imbalances... There was a ground breaking research in biotechnology sometime back producing GOLDEN RICE! It had a gene to produce beta carotene artificially which would combat Vitamin A deficiency. But this fruit king has "it" naturally!! Poly-phenolic antioxidants, flavonoids, minerals, vitamins and pre-biotic dietary fibers makes it an interesting fruit to be consumed by those who are dieting.. Lowers appetite as you feel fuller due to vast range of nutrients in it. If consumed before meals, you tend to eat less.. The fibers in it improves digestion and brings down fat deposition too. Mainly focusing on LDL or bad cholesterol and ultimately bringing down the related adverse effects... Though it has lots of sugars, due to low glycemic index values, wouldn't contribute much to blood sugar levels and not a bad fruit for diabetics...
Mangoes do possess small amounts of copper which acts as co-factors to most of the enzymes in our body and makes it functional. You might be knowing about the usefulness of pyridoxine (Vit B6) in homocysteine regulation in humans required for healthy heart to avoid coronary artery diseases (CAD) and stroke. Mangoes are rich in this vitamin... Some amount of fat is definitely required for uptake of those vitamins which are only fat soluble. For instance, if you are consuming Multivitamin tablet or any Vitamin rich fruits, don't let go wasted... Pop in an almond (contains good fat) and get the benefit of complete absorption of essential vitamins :)
Let me add some fat to a very traditional mango cuisine called as Mavinakayi chitranna or simply Mango Rice made using unripe Tothapuri variant of mango.
