Regarding MUFAs, it has been seen how oleic acid (omega-9 monounsaturated fatty acid) increases PON1 activity [59], which seems to coincide with our results; in relation to vitamin D (specifically vitamin D3 and/or its metabolites), despite its antioxidant and anti-inflammatory activity [60], and that it directly increases the activity of the antioxidant enzyme in ALS, increasing the protection of motor neurons and neuronal vulnerability to glutamate excitotoxicity [61,62], it has not been described in other works that its intake is related to PON1 activity. Here, PON1 is linked to amyotrophic lateral sclerosis.
