Plant-based beverages as milk alternatives? Nutritional and functional approach through food labelling.

Plant-based beverages (PBB) market is largely growing. In this study, 136 beverages made of soy, oat, almond, rice, tigernut, and others (mixtures of various plant materials), from the Spanish market were evaluated through labelling information. Energy value and fat content were intermediate between skimmed and whole cow milk; while fatty acids profile was quite different. Carbohydrate content was usually higher than cow milk, and highly dependent on the addition of sugars. All products provided some dietary fibre. With the exception of soy-based drinks, samples presented lower protein and calcium content than milk (1/3 samples studied were Ca-fortified), and 23% were vitamin D enriched. The claim "No added sugars" was in more than 50% samples. A right labelling and nutritional education of consumers is essential to make adequate choices, since the appearing of many claims is not always indicative of a better-quality product. Plant-based beverages cannot be considered as an alternative to milk, but as a different product, with their own nutritional and functional entity. Their inclusion in a diversified balanced diet can provide interesting functional components, such as soluble fibre or unsaturated fatty acids (mainly soybean and almond drink), which can help improve the health status of the population.

Plant-based drinks for vegetarian or vegan toddlers: Nutritional evaluation of commercial products, and review of health benefits and potential concerns.

There is an increasing trend today towards plant-based diets in western society, often resulting in milk restriction. In the case of very young children, the direct substitution of milk by other foods, without proper nutritional advice, may lead to a lack of nutrients and hence to growth and development alterations. This study focuses on the nutritional assessment of various commercially available plant-based drinks, to determine their adequacy as alternatives to ruminant milk, in relation to the nutritional requirements of toddlers (1-3 years old), and to establish whether other sources of nutrient supplementation may be needed, as well as any other possible positive and /or negative health effects associated to their consumption. A sample of 179 commercial plant-based drinks (almond, coconut, hemp, oat, rice, soy, tigernut) were chosen and their nutrient contents were compared to the EFSA nutrient reference values for toddlers. The scientific literature on the presence of bioactive and/or undesirable compounds was reviewed. None of the plant-based drinks studied should be considered as a milk substitute, since they are different food products with a different composition. However, from the results obtained, the best choice for toddlers who do not consume milk would be to consume at least 250 mL/day of fortified soy drink (for its higher amount and quality of protein, polyunsaturated fatty acids and phytosterols), and always in the context of a carefully-balanced diet. Almond, hemp or oat drinks are other alternatives that can be used in combination or for soy-allergic toddlers. The key nutrients that should be fortified in plant-based drinks are: vitamins A and B12, calcium, zinc and iodine, as they represent the most significant nutritional differences with milk; vitamin D would also be desirable. Of these, vitamins A, B12, D and calcium, are easily found in many commercial plant-based drinks on the Spanish market (most frequently in soy drinks), unlike iodine and zinc, which were not added to any. Given the fish restriction in vegetarians/vegans and the fact that plant-based drinks provide high amounts of phytates and tannins, which act as antinutrients, a good strategy for the industry would be to fortify plant-based drinks with iodine and zinc to improve the nutritional value of products aimed to vegetarians/vegans.

[Giant orthotopic ureterocele. Diagnosis by ureteral jet detection with doppler color ultrasonography]. / Ureterocele gigante ortotópico. Diagnóstico por detección del jet ureteral mediante ecografía doppler color.

OBJECTIVE: To present an additional case of orthotopic ureterocele in a patient that consulted for hematuria and outlet obstruction, with special reference to the utility of non-invasive color doppler ultrasound in the diagnosis of this condition. METHODS/RESULTS: This condition was suspected on detecting a ureteral jet inside a cystic lesion of the bladder. The diagnosis was confirmed by IVP and cytoscopy. Treatment was by transurethral resection with good functional results. CONCLUSION: Color doppler ultrasound is useful for the diagnosis of ureteroceles, particularly in patients in whom contrast or ionizing radiation must be avoided.
