Sefton Central Labour MP Bill Esterson is working with a Lydiate campaigner to get improved food labelling on products that contain an ingredient which experts say causes type 2 diabetes.
Lydiate's Len Cole raised his concerns with the MP after discovering research that linked fructose corn syrup with an increase in the prevalence of diabetes.
Bill has taken Len's concerns to the Department for Food and Rural Affairs (Defra).
Bill said: "Len raises some valid concerns about the links between fructos and the rise in type 2 diabetes.
"He suggests that food labelling should be included to ensure that consumers know that the item contains fructose as an ingredient.
"Type 2 diabetes is becoming a major problem in this country. More and more people are being diagnosed with the condition and more and more people are having to manage the symptoms.
"Scientists tell us that fructos is a contributory factor in the prevalence of diabetes. I therefore want to know when food contains fructos before I eat it."
Fructos is a common sweetener that is found in many every day foods, from cakes and cereals to soft drinks.
Len, 72, said: "The supermarkets are taking full page adverts out in national newspaper saying sorry about finding horsemeat in some of their products. But as far as I know, no one has died from eating horsemeat.
"But this fructos corn syrup is causing diabetes. It's wrong. They should be saying exactly what's in the food and what that food is doing.
"I've got type 2 diabetes myself. People shouldn't be unknowingly eating food which is bad for them. We need to know what's in our food.
"People should be made aware that there is a problem with that ingredient and there should be warning labels on any food that contains it."
Bill has also raised the issue of ensuring that ingredients are fully labelled in bakeries.
Bill said: "Len raises a very good point about bakeries not listing the ingredients in much of their products, particularly in supermarkets.
"Fructos is present in bread. It is present in cakes.
"Again, consumers need to know what they are eating and the effects the ingredients can be having on them."
