In summary, Omega-9.
Omega-9s are a category of monounsaturated fatty acids . Monounsaturated fatty acids are fatty acids that only have one double bond. Oleic acid is the main fatty acid in the omega-9 family. Elaidic acid, gondoic acid, Mead's acid, erucic acid, and nervonic acid are also part of it. Synthesised by the body from other unsaturated fats, omega-9s are not considered essential fatty acids. However, this family of fats remains necessary for various organic processes.
Generally, a large amount of omega-9 is found in olive oil, hazelnut oil, rapeseed oil and avocado. Omega-9s are also present in macadamia nuts, hazelnuts, almonds, cashew nuts, pecans and even pistachios. In addition to being beneficial for cardiovascular health, potentially helping to reduce skin inflammations, these fatty acids also have certain virtues on the health of the appendages. Indeed, they could notably contribute to maintaining the good health of the nails. What about it?
Does oral intake of omega-9 have effects on the nails?
The connection between diet and nails is often discussed. It is suggested that the consumption of omega-9 may be beneficial for nail health.
However, it is important to highlight that no study has shown that oral intake of omega-9 improves nail health.
In the absence of concrete scientific evidence, we are not in a position to take a stance on this matter. It is recommended to discuss this with your doctor or a health professional before taking any action for your nails in order to find an approach suitable for your situation.
