Overconsumption of omega-6 plant oils and food allergies

.
Interesting article at The Telegraph: Oily fish and nuts 'cut chance of food allergies'

(From Happy Dietetitian at Wordpress)


Quote:
Academics have discovered that omega-3 fatty acids - found in fish like salmon, mackerel and tuna, as well as walnuts, pumpkin seeds and linseeds - prompt the gut to develop in a way that boosts the immune system. And they warn that more children could now be at risk of food allergies than in the past because consumption of such foods has fallen. The team, from France's National Agricultural Research Institute (INRA), found that when mothers-to-be ate a diet high in a particular group of polyunsaturated fatty acids (PUFAs), the gut walls of their offspring were more permeable.

My comment:
   - Consumption of such food has fallen largely because of the official medical authorities recommendations that overemphasized vegetables, fruits and specific plant oils that are very high in omega-6, and discouraged consumption of fish, nuts and animal produce that contain omega-3 fatty acids.

There is some evidence that nuts (such as almonds) containing high proportion of fat as omega 6, and little or no omega 3, are nonetheless protective in diseases aggravated by linoleic acid from oils.

For example: Higher vegetable fat intake had a stronger relationship with increased risk of AMD progression with an RR of 3.82 (95% confidence interval, 1.58-9.28) for the highest quartile compared with the lowest quartile (P trend =.003). Saturated, monounsaturated, polyunsaturated, and transunsaturated fats increased the likelihood of progression (RR, 2.09 and P trend =.08; RR, 2.21 and P trend =.04; RR, 2.28 and P trend =.04; RR, 2.39 and P trend =.008, respectively). Higher fish intake was associated with a lower risk of AMD progression among subjects with lower linoleic acid intake. Processed baked goods, which are higher in some of these fats, increased the rate of AMD progression approximately 2-fold, and nuts were protective.

Most nuts are not good sources of omega 3, generally the plant that grows from a seed converts the LA to ALA and the animals that eat the plant's greens, roots, fruits then convert the ALA to EPA and DHA.

If we relied less on dried foods - grains, legumes and their oils - and less on animals fed on these, and ate more parts of growing vegetables, and animals fed on these, the omega 6/3 balance would sort itself.

You've probably seen this but just in case I believe this could be an important paper.

It's about heart disease. The reason I’m looking so hard at this stuff is my Dad is still in the hospital from quadruple bypass surgery. Ouch. It’s causing me a bit of distress. He I think will be fine. Anyways this guy is 98 and has been studying heart disease since the fifties. He claims he knows what causes it. I found it through,
