KEY POINTS:
The New Zealand Food & Grocery Council (FGC) says pregnant women don't eat enough bread to justify a decision to make fortification of bread with folic acid mandatory.
Food Safety Minister Annette King yesterday said the decision, jointly made with Australia, was "a triumph for humanity and common
sense".
In New Zealand the acid would be added as the bread was made and Australia had decided to add it to flour -- something the New Zealand Green Party opposed.
"New Zealand women do not get enough natural folate in the diet to prevent a large number of babies being born with devastating neural tube defects, the most common of which are spina bifida and hydrocephalus," Ms King said.
Opponents of the idea have raised concerns that the fortification could have side effects such as an increase in the number of twins and bakers have said it would add costs.
FGC executive director, Brenda Cutress, said pregnant women would need to eat 11 slices of bread a day to get the necessary amount.
She said research by Professor Leonie Segal of the Monash University -- found at the option was not cost effective and recommended promoting folic acid supplements through a public campaign targeting women of child bearing age.
"It's laudable to seek a way of reducing birth defects, but it is more important to have a solution that actually works," she said."
However Ms King expected the change would see between four to 14 fewer neural tube defect affected pregnancies a year.
"While fortification alone won't provide the recommended amount of folic acid that should be taken before and during pregnancy, it will be enough to make a difference."
Folic acid supplements were still recommended for women planning a pregnancy.
Organic and non-yeast leavened breads were exempt from mandatory fortification.
"We promised that New Zealanders will have a choice, and we have delivered on that promise, but I urge all women considering a diet low in folate or folic acid to consult their doctor about the risks and consequences," Ms King said.
In New Zealand fortification of bread at levels of 80 to 180mg of folic acid per 100g of bread will occur in the bread-making process and will be mandatory two years after the standard is gazetted.
Dietary modelling studies showed this would increase folic acid intake in New Zealand women by 140 mg of folic acid a day, she said.
"This is still below the 400 mg daily intake recommended by the Ministry of Health for women in the four weeks before and first twelve weeks of their pregnancy, and all pregnant women should ask their doctor about the right folic acid supplement for them."
There would a review to see how the decision was working after two years.
Green MP Sue Kedgley said she was pleased that organic bread was exempt. Her party opposed the Australian model of all flour containing folate.
"We are pleased that the Minister has not slavishly followed Australia, and required folate to be added to all flour, and has instead come up with a New Zealand based solution -- of adding folate during the breadmaking process."
She said it would be hard for some small bakeries to implement the change because of measuring difficulties for small batches.
