600The NutriGen project will be using nutrigenomic methods to determine the effectiveness of treatments with specific dietary foods, on the basis of genetic risk predisposition (genetic signature) of obese individuals.
NutriGen project specific aim 1. Establishing a genetic signature model, involved in the donation of methyl groups and unsaturated omega-6/3 fatty acids metabolism, with a high predictive value for classification of dyslipidemia and insulin resistance in obese subjects.
Establishing a genetic signature model in obese adults with dyslipidemia.
Establishing a genetic signature model in obese children with insulin resistance. c. Establishing a correlation between blood/plasma concentrations of the relevant metabolites, genetic signatures and dyslipidemia profile of adults, and respectively a profile for insulin resistance in obese children.
NutriGen project specific aim 2. Determining the efficacy of a dietary food specific treatment, which is also correlated with a genetic signature (nutrigenomics), based on the correlations defined in objective 1:
Implementation of a treatment with dietary foods (for adults), in the presence/absence of other already prescribed treatments;
Implementation of a treatment with dietary foods (for children), in the presence/absence of other already prescribed treatments.
Administration of supplements containing methyl-donors: betaine, 5-MTHF (L-5-methyltetrahydrofolate), Vitamin B12, choline bitartrate, ALA (alfa-linolenic acid), EPA (eicosapentaenoic acid), DHA(docosahexaenoic acid)
The intervention will consist Administration of supplements containing methyl-donors (as capsules) containing: 2 g betaine, 800 ug (micrograms) 5-MTHF (L-5-methyltetrahydrofolate) + 1000 ug (micrograms) Vitamin B12, 500 mg choline bitartrate, 1 g ALA (alfa-linolenic acid), 700 mg EPA (eicosapentaenoic acid), 280 mg DHA (docosahexaenoic acid). Every week the participants will receive a weekly amount of supplements, in opaque pharmaceutical-grade plastic bottles, adequately coded. Participants will be instructed to consume the daily amounts in 2-3 administrations, immediately after a meal,for a duration of 3 months
The intervention will consist of the Administration of supplements containing methyl-donors (as capsules) containing inactive ingredients with low glycemic index (usually starch-based), and one capsule containing corn oil (1 g). Every week the participants will receive a weekly amount of supplements, in opaque pharmaceutical-grade plastic bottles, adequately coded. Participants will be instructed to consume the daily amounts in 2-3 administrations, immediately after a meal,for a duration of 3 months
The intervention will consist of the Administration of supplements containing methyl-donors (as syrup) containing: 1 g betaine, 400 ug (micrograms) 5-MTHF (L-5-methyltetrahydrofolate) + 500 ug (micrograms) Vitamin B12, 250 mg choline bitartrate, 0.5 g ALA (alfa-linolenic acid), 700 mg EPA (eicosapentaenoic acid), 140 mg DHA (docosahexaenoic acid). Every week the participants will receive a weekly amount of supplements, in opaque pharmaceutical-grade plastic bottles, adequately coded. Participants will be instructed to consume the daily amounts in 2-3 administrations, immediately after a meal,for a duration of 3 months
