the european food safety authority (efsa) this morning published 536 health claims in 73 opinions in the fifth batch of general function claims. many positive opinions, many more negative in the latest batch of efsa health claim missives probiotic claims continued to be rejected under the nutrition and health claims regulation (nhcr), but there were positive opinions including: dietary fibres and blood cholesterol; cereal fibre and bowel function; carbohydrate-electrolyte drinks and endurance performance; low sodium and blood pressure; dietary fibre and blood glucose; melatonin and sleep; very low calorie diets and body weight. of the rejections, efsa said, “they were not sufficiently specific, such as claims on “women’s health” or “mental energy”, or that they referred to food categories which were considered to be too broad, such as “fruits and vegetables”, “dairy products”, to be linked to specific effects.” “other claims were unfavourably assessed because they were not supported by any relevant studies in humans. such studies are central to the establishment of a cause and effect relationship between the food or substance concerned and the beneficial health effect claimed.” efsa has now assessed 2723 article 13, general function health claims, and has just 35 remaining, to be published in a mini-batch 6 in july this year. “efsa is liaising closely with the european commission and stands ready to provide any further support which could be required in the assessment of ‘general function’ health claims,” it said. initial scan responding from germany, christiane alexander, phd, of the consultancy analyze&realize said the trends were similar to those of previous batches. “again the same picture: many negative opinions and several opinions on claims that were already assessed previously,” she said. “characterisation was not found sufficient in several cases. this was seen previously.” of a positive lactose opinion, she wondered: “reduced lactose-containing products are decreasing symptoms in lactose-intolerance people. why is this not a nutrition content claim?” probiotic researcher bruno pot, phd, of the pasteur institute in lille, france, said the batch demonstrated the, “same old things, nothing new under the sun”. “still no in vitro and pre-clinical research is accepted, still there is too little explanation of statistics, still many references not available or in japanese.” but he added of some of the probiotic rejections: “it is interesting that the vaginal route of administration nor the naso-gastric tube are considered relevant to human nutrition. this might be logical to some point, but will surely be extended to skin probiotics for example. it will be interesting to follow what will happen with these products: where to classify them?” alexander addressed the issue of target populations in a rejected eye health claim, noting, “dry eye patients are not acceptable for extrapolation to the general population.” winners: oat and barley grain fibre increases faecal bulk (in “high fibre” foods). rye fibre benefits bowel function (in “high fibre” foods). beta-glucans from oats and barley reduce post-prandial glycaemic responses when 4g of beta-glucans from oats or barley are consumed for each 30 g of available carbohydrate. previous cholesterol opinion affirmed. reduced dietary sodium intake helps maintain normal blood pressure. very low calorie diets (vlcds) can reduce body weight among obese adults in compliance with the specifications and conditions of use laid down in codex stan 203-1995. glycaemic carbohydrates help maintain normal brain function if 130g consumed daily. sodium maintains normal muscle function but claim not approved because deficiencies leading to impaired muscle function in eu populations not demonstrated. dietary intake of fats helps normal absorption of fat-soluble vitamins but claim not approved due to absence of fat deficiency in eu diets. carbohydrate-electrolyte solutions enhance water absorption during exercise and maintain endurance performance (when drink contains 80-350kcal/l from carbohydrates, at least 75% of the energy from high-gi carbohydrates and 20-50mmol/l sodium). reduced lactose food content may help decrease gastro-intestinal discomfort caused by lactose intake in lactose intolerant individuals. melatonin helps sleep if 1mg consumed close to bedtime. chitosan can help maintain normal blood ldl-cholesterol concentrations if 3g consumed daily. arabinoxylan produced from wheat endosperm can reduce post-prandial glycaemic responses if 8g of arabinoxylan-rich fibre consumed per day. fructose when replacing sucrose or glucose in foods or beverages can reduce post-prandial glycaemic responses. losers: silicon does not protect against aluminium accumulation in the brain;
