Effects of reducing processed culinary ingredients and ultra-processed foods in the Brazilian diet: a cardiovascular modelling study.

OBJECTIVE: To estimate the impact of reducing saturated fat, trans-fat, salt and added sugar from processed culinary ingredients and ultra-processed foods in the Brazilian diet on preventing cardiovascular deaths by 2030. DESIGN: A modelling study. SETTING: Data were obtained from the Brazilian Household Budget Survey 2008/2009. All food items purchased were categorized into food groups according to the NOVA classification. We estimated the energy and nutrient profile of foods then used the IMPACT Food Policy model to estimate the reduction in deaths from CVD up to 2030 in three scenarios. In Scenario A, we assumed that the intakes of saturated fat, trans-fat, salt and added sugar from ultra-processed foods and processed culinary ingredients were reduced by a quarter. In Scenario B, we assumed a reduction of 50 % of the same nutrients in ultra-processed foods and processed culinary ingredients. In Scenario C, we reduced the same nutrients in ultra-processed foods by 75 % and in processed culinary ingredients by 50 %. RESULTS: Approximately 390 400 CVD deaths might be expected in 2030 if current mortality patterns persist. Under Scenarios A, B and C, CVD mortality can be reduced by 5·5, 11·0 and 29·0 %, respectively. The main impact is on stroke with a reduction of approximately 6·0, 12·6 and 32·0 %, respectively. CONCLUSIONS: Substantial potential exists for reducing the CVD burden through overall improvements of the Brazilian diet. This might require reducing the penetration of ultra-processed foods by means of regulatory policies, as well as improving the access to and promotion of fresh and minimally processed foods.

Food and beverage industries' participation in health scientific events: considerations on conflicts of interest.

Several sectors of the industry (pharmaceutical, food, and other) often occupy a prominent position in scientific meetings on health. The aim of this article is to discuss the participation of food and beverage industries (Big Food and Big Soda) in events organized by scientific institutions in health and nutrition, highlighting potential conflicts of interest in such partnerships. As an example, the authors report the case of a Brazilian national event organized by a nutrition scientific association in 2011. Focused on the theme "Evidence-based Nutrition," the event's scientific program was largely influenced by corporate sponsors. For example, a symposium at this congress was organized by a beverage company known worldwide for its sugar-sweetened products and classified as the "diamond sponsor" of the event. While debating the adoption of healthy lifestyles in the current scenario of rising occurrence of obesity, the rationale for health promotion was reduced to providing information that would motivate rational individual choices, thus ignoring any political, economic, cultural, marketing, and social factors involved in the global process of nutrition transition. The authors conclude that conflicts of interest are present in the participation of food and beverage industries in health scientific events. The industries' strategy attempts to grant legitimacy to the production and marketing of their products through an association with adequate health practices. Health professionals and policy-makers should reflect on such partnerships because their main purpose is to generate profit, not the promotion of public health.

Food purchasing sites. Repercussions for healthy eating.

Changes in the food system are associated with the increase in consumption of foods with low nutritional value in recent decades. Data on food purchasing for household consumption, collected from the Instituto Brasileiro de Geografia e Estatística (IBGE--Brazilian Institute of Geography and Statistics) Household Budget Survey (HBS) in 2002-3, were used to describe the contribution of food purchasing sites (FPS) to the diet of Brazilian families. All the 241 distinct FPS mentioned in the HBS were grouped into ten categories, according to the nature of the products available. Food acquisitions were organized into seven groups. Supermarkets and hypermarkets accounted for 49% of the acquisitions and were the main source of six out of the seven food groups. Street markets and greengroceries stood out in the acquisitions of fruits and vegetables, accounting for 39% of this market. The large contribution of supermarkets and hypermarkets to the diet shows the need for healthy eating promotion policies aiming at these locations. Street markets and greengroceries represent important allies for healthy eating.

18O-Labeled lipid hydroperoxides and HPLC coupled to mass spectrometry as valuable tools for studying the generation of singlet oxygen in biological system.

Decomposition of lipid hydroperoxides (LOOH) is known to generate toxic products capable to induce tissue injury. We have recently confirmed that decomposition of LOOH into peroxyl radicals is a potential source of singlet oxygen ((1)O(2) in biological system. Using (18)O-labeled linoleic acid hydroperoxide (LA(18)O(18)OH) in the presence of Ce(4+) or Fe(2+), we observed the formation of (18)O-labeled (1)O(2) ((18)[(1)O(2)]) by chemical trapping of (1)O(2) with 9,10-diphenylanthracene (DPA) and detecting the corresponding (18)O-labeled DPA endoperoxide (DPA(18)O(18)O) by HPLC coupled to tandem mass spectrometry (HPLC-MS/MS). (18)O-Labeled alcohol and ketone were also detected providing further evidence for the generation of (1)O(2) by the Russell mechanism. Similarly the reaction of LA(18)O(18)OH with peroxynitrite also generated (18)[(1)O(2)].In conclusion, these results indicates that the use of (18)O-labeled LOOH associated with HPLC-MS/MS can be an useful tool to clarify mechanistic features involved in the reaction of LOOH in biological media.

Mientras se debatía sobre la adopción de modos de vida saludables en el contexto actual de incremento de los casos de obesidad, el ámbito de promoción de la salud se redujo a suministrar información que incitara a elecciones individuales racionales, sin que se tuvieran en cuenta los factores políticos, económicos, culturales, mercadotécnicos y sociales que el proceso mundial de transición nutricional involucra. Los autores concluyen que los conflictos de intereses existen en la participación de las industrias de la alimentación y las bebidas en acontecimientos científicos sobre temas de salud.

Direct evidence of singlet molecular oxygen [O2(1Deltag)] production in the reaction of linoleic acid hydroperoxide with peroxynitrite.

Peroxynitrite (ONOO-), a biologically active species, can induce lipid peroxidation in biological membranes, thereby leading to the formation of various hydroperoxides. We report herein on the formation of singlet molecular oxygen [O(2) ((1)Delta(g))] in the reaction of peroxynitrite with linoleic acid hydroperoxide (LAOOH) or (18)O-labeled LAOOH. The formation of O(2) ((1)Delta(g)) was characterized by (i) dimol light emission in the red spectral region (lambda > 570 nm) using a red-sensitive photomultiplier; (ii) monomol light emission in the near-infrared region (lambda = 1270 nm) with a liquid nitrogen-cooled germanium diode or a photomultiplier coupled to a monochromator; (iii) the enhacing effect of deuterium oxide on chemiluminescence intensity, as well as the quenching effect of sodium azide; and (iv) chemical trapping of O(2) ((1)Delta(g)) or (18)O-labeled O(2) ((1)Delta(g)) with the 9,10-diphenylanthracene (DPA) and detection of the corresponding DPAO(2) or (18)O-labeled DPA endoperoxide by HPLC coupled to tandem mass spectrometry. Moreover, the presence of O(2) ((1)Delta(g)) was unequivocally demonstrated by a direct spectral characterization of the near-infrared light emission attributed to the transition of O(2) ((1)Delta(g)) to the triplet ground state. For the sake of comparison, O(2) ((1)Delta(g)) deriving from the thermolysis of the endoperoxide of 1,4-dimethylnaphthalene or from the H(2)O(2)/hypochlorite and H(2)O(2)/molybdate systems were also monitored. These novel observations identified the generation of O(2) ((1)Delta(g)) in the reaction of LAOOH with peroxynitrite, suggesting a potential O(2) ((1)Delta(g))-dependent mechanism that contributes to cytotoxicity mediated by lipid hydroperoxides and peroxynitrite reactions in biological systems.
