The
Moringa oleifera was featured on the popular talk show ABC "The View"
as a "Slim Down Super Food" due to its incredible energy boosting,
nutrient dense, weight loss and antioxidant properties, without side effects.
1. Nutritional content of fresh Moringa oleifera
tree leaves
Moringa oleifera tree leaves belong
to the family of dark green leafy vegetables, a food group particularly rich in
nutrients. In particular, the leaves are a good source of proteins, calcium,
iron, ß-carotene (converted to vitamin A in the human body), vitamin C and
vitamin E. In addition, Moringa leaves have a high dry matter content (around
20-25%) compared to most other plant food sources (generally around 10%). This
makes it even more beneficial as a fresh vegetable since 100 grams of fresh
leaves will bring twice as much nutritive material as 100 grams of most other
vegetables.
Eating 100 grams fresh
Moringa oleifera tree leaves provides you with as much protein as an egg, as
much calcium as a big glass of milk, as much iron as a 200 grams beef steak, as
much vitamin A as a carrot and as much vitamin C as an orange.
Indeed, 100 grams fresh Moringa oleifera leaves
are enough to cover:
• 30 to 100% of the
daily recommended intake of calcium (30 to 50% for teenagers, 40 to 60% for
adults, children and pregnant and breastfeeding women, 80 to 100% for young
children below 3 years old)
• 25 to 80% of the daily recommended intake of iron (25% for pregnant women, 40-60% for teenagers and women, 50 to 100% for men and children).
As for vitamins, the recommended daily intake for vitamin A varies from 400 μg retinol equivalents (young children) to 1,000 μg retinol equivalents (breastfeeding women).
Therefore, 100 grams of fresh Moringa tree leaves could
theoretically cover 100% of daily needs, but this is highly variable depending
on storage conditions and how they are eaten, as vitamin A degrades over time
and when exposed to light or heat. Similarly, 100 grams of fresh Moringa leaves
could cover 100% of the vitamin C requirements, for which the recommended daily
intake varies from 60 mg (young children) to 130 mg (breastfeeding women), but
this vitamin degrades quickly with time and during cooking.
For optimal nutrient retention, it is advised to consume fresh Moringa tree leaves shortly after harvesting and to cook the leaves for a short time (a few minutes only), or even to eat them raw if they are young and tender
10 grams of Moringa leaf powder per day cover:
Calcium
• About 30% of the recommended daily intake for children between 1 and 3 years old.
• About 25% of the recommended daily intake for children between 4 and 9 years old as well as adult women.
• About 15% of the recommended daily intake for teenagers and women over 55.
• About 30% of the recommended daily intake for children between 1 and 3 years old.
• About 25% of the recommended daily intake for children between 4 and 9 years old as well as adult women.
• About 15% of the recommended daily intake for teenagers and women over 55.
Iron
• About 30% of the recommended daily intake for children between 1 and 12 years old.
• About 15% of the daily recommended intake for teenagers.
• About 20% of the daily recommended intake for adults over 55.
• About 12% of the recommended daily intake for adult women.
• About 7% of the recommended daily intake for pregnant women.
• About 30% of the recommended daily intake for children between 1 and 12 years old.
• About 15% of the daily recommended intake for teenagers.
• About 20% of the daily recommended intake for adults over 55.
• About 12% of the recommended daily intake for adult women.
• About 7% of the recommended daily intake for pregnant women.
Vitamin A
• 50 to 100% of the recommended daily intake for all population categories.
• 50 to 100% of the recommended daily intake for all population categories.
Moringa oleifera leaf
powder can be used somewhat like dried spirulina, a nutritionally rich, green
seaweed, often used as a dietary supplement.
2. Nutritional content of dry Moringa oleifera
tree leaf powder
Another way of
consuming Moringa leaves is
to dry them and reduce them into powder, making it easier to store and use at
any time. To ensure the good nutritional and microbiological quality of the
leaf powder, its water content has to be lower than 7%, the drying time should
be as short as possible and the drying temperature not too high (no more than
50-55°C).
Even if a large amount of the vitamins are lost during drying and storage, the leaf powder still constitutes a very rich nutritional supplement, since it is a concentrate of the Moringa oleifera leaves

Moringa tree leaf
powder can be stored for some time before it is consumed. If so, the leaf
powder has to be stored in a water- air- and light-proof container to preserve
as much vitamins as possible and avoid microbial contamination. In storage, the
protein and mineral contents will be preserved for up to six months, whereas a
loss of up to 50% of vitamins can be reached after six months of storage.
Once the container is opened, the leaf powder should be consumed quickly (within one week) since its water content will increase and it will be exposed to microbial contamination. For this reason, it is advised to package Moringa leaf powder in rather small containers.
3. Nutritional content of cooked Moringa
oleifera leaves
Fresh Moringa leaves
can be eaten raw, if they are very young and tender, but usually they are
cooked. Even if cooking the leaves destroys a part of their nutrients, notably
vitamins, others become easier to assimilate. For this reason, it is important
to consider various ways of cooking the leaves and to understand how to
preserve the maximum amount of nutrients. This can be achieved by associating Moringa tree
leaves with other ingredients that enhance the availability of nutrients, by
cooking the leaves only for a short time, or by keeping the liquid (water,
sauce) in which the Moringa leaves are cooked. Using Moringa leaf powder is
also a way of preserving nutrients (although some have been lost during drying
and storage), as the powder can be added to food after cooking.
Moringa oleifera-
Vitamin C
A study from Sri Lanka showed that on average, leafy vegetables lose 32% of their vitamin C content when they are boiled for five minutes, and 54% in ten minutes. Steaming is less damaging, with 15% loss in five minutes and 39% loss in ten minutes. Cooking Moringa oleifera tree leaves or Moringa oleifera tree leaf powder the least possible time is thus a good way to preserve the vitamin C content.

Moringa oleifera - Beta-carotene
The World Vegetable Centre (AVRDC, Taiwan) showed that the retention of total carotene and beta-carotene of Moringa oleifera tree leaves was enhanced by adding oil to the leaves during pressure cooking (76-99% of retention with oil against 46-63% without).
Moringa oleifera - Iron
The bioavailability of nutrients is the ability they have to be digested and used by the human body. The bioavailability of the iron provided by plants is lower than when provided by meat. A good way to improve the availability of iron to the body is to add vitamin C to the dish. This can be done by using lemon juice, lemon peel or fresh tomatoes.

AVRDC demonstrated that boiling Moringa tree leaves in water enhanced the in vitro iron bioavailability of fresh leaves and leaves dried powder by 3.5 and 3 times, respectively. In addition, boiling the leaves in water enhanced aqueous antioxidant activity. This shows that cooking Moringa tree leaves does not necessarily have a negative impact on nutrient intake. The heat destroys some of the vitamin C, but improves the assimilation of iron. The best option is to vary consumption modes.
4. Water soluble and fat soluble vitamins
Vitamin C and all the
B vitamins contained in the Moringa oleifera tree leaf are water-soluble. Other
vitamins are soluble in fat: such is the case of vitamin A (ß-carotene) and E
(a-tocopherol). When cooking fresh or dried leaves, the cooking water should be
kept to benefit from the vitamins B and C, soluble in water. In addition, to
render the fat-soluble vitamins A and E available, it is suggested that the
leaves be cooked using oil or other sources of fat. Ideally, the Moringa leaves
should be quickly boiled in a small quantity of water. Add both Moringa Oleifera tree leaves and the
cooking water to a sauce containing a source of fat. This way both
water-soluble and fat-soluble vitamins, only slightly diminished by cooking,
are made available.
COOL FACT: Mama's Best Friend
Moringa Oleifera Nutrition
The Moringa Tree, Also Known As Mama's Best Friend.
Moringa has been clinically proven to increase the production of breast milk whether it is consumed before or after the birth of a baby.Mothers who took Moringa were shown to produce more than 2x the amount of breast milk than those who didn't.We all know instinctively that breast milk is the ultimate food prescribed by nature for the infant child and Moringa can be instrumental in helping mothers produce more of this precious food.
