Heart disease is an inflammatory disease, omega 6 with or without sugar cause inflammation of the arteries that cholesterol sticks to.

A few years ago I started taking flaxseed oil to get some omega 3 into the body to ward of diabetes typeII and my hay fever disappeared never to be seen again , cholesterol dropped as well as blood sugar.

The excessive omega 6 could also be causing or increasing child allergies. When I was at primary school in the 60s, all kids ate peanut paste, now most children die if they eat peanuts. Women brought up on fast food cooked in high omega 6 oils could develop antibodies that when past over to baby cause allergies.

Worth a thought Vince

Sorry for the delay in getting to this but we have been inundated as you might imagine.
I do a lot of research on the role that fatty acids play in our body. Our immune system is regulated by those fatty acids and the amount of omega 6 and the amount of omega 3 we take in has shifted to more omega 6 than omega 3. This causes our immune system to rev-up and it over compensates for the damage we might have in our body. Omega 3 helps the immune system to rest and when called upon can rev-up to fight either a virus or stress. If our body is overloaded then it takes longer to fight and this is when people get sicker than they should. In order for our body to cope with this it, it sends the overload to an organ causing damage to that organ and our skin is the largest organ we have and cops it the most. Others might get ulcers or migraines and other ailments. This is just our body trying to deal with it all. The high amount of omega 3 found in the chia seed puts back that much needed omega 3 from a food source which makes its way into the intestinal track where it gets broken down and used by the body. The body is designed to function at a ratio of omega 3 and omega 6 in equal parts. The average Australian diet is around 18 omega 6 to 1 omega 3 and should be no more than 4 to 1. They compete against each other for an enzyme that breaks them down to be sent to every cell in our body. If we have more omega 6 then this doesn’t allow the omega 3 to get broken down as efficiently.
Now here I must state that I am not a Doctor or medical professional in any way and what I say above is what I have found while studying the metabolic process that occurs in our body of the essential fatty acids, which I have done for my own use to help my body work correctly.
So my theory is the nutrients found in chia seeds especially the high omega 3 is what helps our body do what it should by getting the omega 3 to omega 6 ratio closer to a 1 to 1 and how the body gets those nutrients and uses them from chia seeds better than any other source of omega 3 is what makes them work. I recommend speaking to your Doctor about any condition and let them know you are taking chia seeds or intend to. Again this is my opinion and should never replace medical advice.
