Four Position Papers from GREP-AEDN
  • Country – Spain
     
    1. GREP-AEDN POSITION PAPER ON THE FLASH DIET
     
    The Review, Study and Scientific Position Statement Group of the Spanish Association of Dietitians-Nutritionists (GREP-AEDN) prepared a position paper on the "Flash Diet", in order to respond to the numerous inquiries from members of the AEDN and media. Therefore, taking into account the Code of Ethics of the profession of Dietitian-Nutritionist, and in particular the responsibilities and commitments of Dietitians-Nutritionists towards society, the GREP-AEDN has issued a scientific opinion on this "diet" with the aim to help both health professionals engaged in Human Nutrition and Dietetics, and the general population, in making informed and responsible decisions.
     
    The position of GREP-AEDN is to strongly discourage people following the "Flash Diet", for the following reasons:
    1. It has no scientific basis. No human studies that have evaluated its effectiveness and safety have been found. The search strategy used in PubMed-Medline (database recommended by the National Health System) has been: ("Obesity" [Mesh] OR "Obesity, Abdominal" [Mesh] OR "Overweight" [Mesh]) AND Flash
    2. The statements that appear in its website break the law.
    3. It meets most of the characteristic criteria of fraudulent diets or methods to lose weight.
    4. Dietary approaches like the "Flash diet" have been associated with health risks such as weakness, bone fracture risk, long term weight gain, metabolic syndrome, kidney damage, gastrointestinal disorders, depression and behavioural disturbances.
     
    2. GREP-AEDN POSITION PAPER ON THE "ENTERAL TUBE DIET" FOR WEIGHT LOSS
     
    The Review, Study and Scientific Position Statement Group of the Spanish Association of Dietitians-Nutritionists (GREP-AEDN) issued a position paper on the "Enteral Tube Diet" as a method for weight loss. GREP-AEDN analysed the scientific literature and concluded that the method is characterized by:
    • The lack of scientific support.
    • The contradiction with the Spanish Society for the Study of Obesity (SEEDO) criteria for therapeutic intervention.
    • The potential breach of the 1999/21/CE Directive and its transposition into the Spanish law by Real Decreto 1091/2000.
    • The potential health risks associated with the diet.
    • Most of the characteristic criteria of fraudulent diets or methods to lose weight.
    • The potential breach of Real Decreto 1907/1996.
     
    Therefore, the GREP-AEDN position is to discourage people following the "Enteral Tube Diet" (also known as the "Backpack Diet ", "Tube Diet", "Nasogastric Diet " or "Eating by the nose Diet").
     
    3. GREP-AEDN POSITION PAPER ON THE "ISODIETA"
     
    The Review, Study and Scientific Position Statement Group of the Spanish Association of Dietitians-Nutritionists (GREP-AEDN) wrote in 2009 a preliminary report on a book that appeared in the media called “Isodieta (dieta isolipoproteica), adelgazante y revitalizadora”  written by Mr. Jaime Brugos. This report has been updated and reviewed. Taking into account the discussion in its position paper, the GREP-AEDN strongly discourages the statements from Mr. Jaime Brugos and following the Isodieta, considering it as a "dietary fraud" because "Isodieta" limits the consumption of a food or some food groups, foods are classified as "good" or "bad", it exaggerates or rejects the scientific basis of the nutrients and advocates the consumption of dietary supplements which are sold by the author, and Mr. Brugos advocates nutritional claims or statements that contradict reputable healthcare groups.
     
    4. NUTRIENT LOSSES IN DOMESTIC MANIPULATION OF FRUITS AND VEGETABLES
     
    In response to a request from "5 a day" Association for the Promotion of the Consumption of Fruits and Vegetables (which has a partnership agreement with AEDN), The Review, Study and Scientific Position Statement Group of the Spanish Association of Dietitians-Nutritionists (GREP-AEDN) has written an interesting report on those aspects related to the domestic manipulation of fruits and vegetables (F & V) that may affect their nutritional composition. The paper includes a brief introduction to the concept of "fruit" and "vegetable", as well as a brief update regarding the importance of F & V consumption and their actual intake by the Spanish population.
     
    Regarding domestic handling of F & V and alterations in its nutrient content, the GREP-AEDN examines the effects of storage, mechanical processes like cutting and peeling, fermentation and canning, adding bicarbonate and cooking (boiling, stewing, boiling in a pressure cooker, steaming, frying, baking and using a microwave). Finally, the report includes some advice in relation to methods of handling food.
