Researchers found a connection between the intake of iron and seed oils high in omega-6 polyunsaturated fatty acids (PUFAs) with diabetic peripheral neuropathy (DPN) in people with Type 2 diabetes
Both high dietary iron intake and an elevated iron/PUFA ratio were associated with DPN
While the study evaluated PUFA intake of omega-6 and omega-3 together, it was the ratio of iron/omega-6 that showed a significant association with DPN
One way to help stop the oxidative damage caused by iron intake in the presence of too many omega-6s is to take carnosine or its primary precursor, beta-alanine
Many chronic diseases appear to be the result of a catastrophic cascade of health declines triggered by the long-term consumption of omega-6 seed oils
To protect your health, it is vital that you reduce your intake of industrially processed seed oils as much as you can, which includes virtually all processed foods and fast foods that contain them

The evidence continues to accumulate that avoiding toxic industrially processed seed oils, often referred to as "vegetable oils," is essential to protecting your health, and recent research adds dietary iron to the increased health risks as well, particularly for those with Type 2 diabetes.1

Examples of seed oils high in omega-6 polyunsaturated fatty acids (PUFAs) include soybean, cottonseed, sunflower, rapeseed (canola), corn and safflower.2 Omega-6 is considered to be proinflammatory because of the most common variety, linoleic acid, which will radically increase oxidative free radicals and cause mitochondrial dysfunction.3

But all seed oils have linoleic acid, even "healthy" ones like avocado and olive oil, both of which have the majority of commercially available products adulterated with other seed oils that have even higher levels of linoleic acid. So, only purchase trusted and tested brands and once you have them put the oil in the fridge. The linoleic acid will remain liquid. Simply pour that oil in the trash and your olive or avocado oil will be healthier.

The intake of omega-6 seed oils may also promote inflammation through arachidonic acid by increasing the production proinflammatory compounds. Further, as researchers noted in the journal Nutrients, "In addition, a few studies suggested that omega-6 PUFA is related to chronic inflammatory diseases such as obesity, nonalcoholic fatty liver disease and cardiovascular disease."4

Iron, meanwhile, while necessary for oxygen delivery, mitochondrial electron transport, DNA synthesis and more, can generate oxidative stress that leads to tissue damage, and previous research has found dietary iron intake may be associated with the risk of diabetes. Now, researchers have demonstrated a connection between the intake of iron and PUFAs with diabetic peripheral neuropathy (DPN) in people with Type 2 diabetes.
