Our “genes” are not fixed: “Plasticity” of the genotype by epigenetic mechanisms => important for the phenotypic impact of nutrition.
• Histone and DNA modifications have impact on gene transcription efficiency. Methylation (more stable) and acetylation (more flexible) have impact on chromatin
• Epigenetic modifications have impact on offspring, embryo development, ageing and disease development or prevention => example: Dutch Hunger Winter.
Health status of future parents are very important for the future health of children.
Early healthy nutrition & lifestyle essential for successful healthy life & “ageing”.
