I'm afraid a fair bit of background needs to be set out before the question, please bear with me!

My mother-in-law has just been diagnosed with dry AMD at the age of 89. Her sight is very poor and the inability to read for long is making her miserable.

The leaflets I picked up from the hospital refer to epidemiological studies that show an association with consumption of antioxidant foods (particulary lutein and zeaxanthin) and reduced incidence of AMD. The conventional wisdom as set out in the leaflet now seems to be that one can halt or slow the advance of the disease with appropriate foods or supplements.

I understand that eggs are richest food source of lutein and pink shellfish and salmon have good levels of zeaxanthin. I am therefore baffled to see in the leaflet that the recommended dietary sources of lutein and zeaxanthin are solely vegetable.

The leaflet also refers to epidemiological evidence for an association between AMD and "trans and saturated fats". The dietary advice, however, is simply to stop eating saturated fats.

Even more baffling to hear that the GP has already advised her to stop eating eggs (and, for that matter, bacon) because they are bad for diabetes. Following the doctor's advice on diet, she now eats toast for breakfast and sandwiches for lunch instead of eggs, bacon and so on. Her face lit up when I suggested eating eggs every day, but she is worried about the eggs making her diabetes worse.

**Does anyone have experience of (a) dietary interventions for AMD and/or (b) helping an ageing relative to return to their own (more optimal) traditional food choices after adopting unhelpful medical advice on diet?

Is 89 too late now, to make any difference?**
