Nutrients in our food can have a big effect on how our genes work. This is called epigenetics, which is a fancy way of saying that our genes can be turned on or off without changing the actual DNA. Here are some important ways that the nutrients in our diet can influence this process:
DNA Methylation: Some nutrients, like folate, vitamin B12, and choline, are important for a process called DNA methylation. Methylation can help turn off certain genes. For example, when people don't get enough folate in their diets, it can lead to less methylation in specific genes. This might increase the chance of having certain disorders.
Histone Modification: Nutrients can also change proteins called histones, which help package DNA. For instance, fats known as polyunsaturated fatty acids (PUFAs) can make it easier for genes to be turned on. Studies suggest that a diet high in PUFAs can boost the activity of genes related to inflammation and metabolism by around 30%.
MicroRNA Regulation: Some nutrients can also affect the creation of microRNAs. These are tiny RNA molecules that help control gene activity. Eating a lot of omega-3 fatty acids can change the levels of certain microRNAs, which can influence over 200 genes involved in important body processes.
Health Implications: The way nutrients affect gene regulation can have serious health effects. For example, not getting enough antioxidants is linked to a higher risk of cancer. Some studies have shown that people with low antioxidant intake may have an increased risk of up to 25%.
In summary, what we eat plays a vital role in how our genes behave through epigenetic changes. This can have significant effects on our health.
