Reduction of risk of obesity
A nutritional composition comprising a significant amount of arachidonic acid (ARA) is described. Such nutritional composition is particularly suitable for infants below the age of 3 years, preferably between birth and 12 months of life. The composition can be used to reduce the risk of developing overweight/obesity and/or insulin resistance later in life.
1. A method for reducing the risk of development of obesity and/or insulin resistance later in life, the method comprising:
administering a composition comprising a protein source, a lipid source and a carbohydrate source, the composition does not comprise docosahexaenoic acid (DHA), the lipid source comprises arachidonic acid (ARA) and a polyunsaturated fatty acid selected from the group consisting of linoleic acid (LA), α-linolenic acid (ALA) and a combination thereof, to a mammal in the first 3 years after birth of the mammal, more than 20% of a total energy of the composition is provided by fatty acids, the ARA is present in the composition in an amount from 1.5% to 2% (w/w) of the fatty acids, and the composition is administered to the mammal in an amount that comprises between 5 and 100 mg of the ARA per kg per day.
2. The method of claim 1 , wherein the mammal is a human infant having a predisposition to obesity and/or predisposition to insulin resistance.
3. The method of claim 1 , wherein the lipid source comprises linoleic acid (LA) and α-linolenic acid (ALA) in a ratio of LA:ALA less than 7:1.
4. The method of claim 1 , wherein the composition is administered to the mammal in an amount that comprises between 35 and 85 mg of ARA per kg per day.
5. The method of claim 1 , wherein the composition is administered to the mammal in an amount that comprises between 50 and 60 mg of ARA per kg per day.
6. The method of claim 1 , wherein the protein source is less than 1.85 g/100 kcal of the composition.
7. The method of claim 1 , wherein the composition is administered to the mammal in the first year after birth of the mammal, and the mammal is a human infant.
8. The method of claim 1 , wherein the composition is administered to the mammal in the first 6 months after birth of the mammal, and the mammal is a human infant.
9. The method of claim 1 , wherein the composition comprises between 1.5 and 2 mg ARA/g of the composition.
10. The method of claim 1 , wherein the composition comprises between 0.1 and 1.5 mg ARA/g of the composition.
11. The method of claim 1 , wherein the composition comprises between 5 and 10 mg ARA/g of the composition.
