Immunity-Boosting Spices and the Novel Coronavirus.

Although there is no reported genetic predisposition in contracting coronavirus disease 2019 (COVID-19), the mortality rate varies among different ethnic groups. Here we determined potential correlation between COVID-19 and spice consumption. The data from 163 countries including total cases, total deaths, and total recovered were analyzed. It was observed that there is a clear interrelated prevalence between the total number of COVID-19 cases per million population tested and the gram of spice supply per capita per day. Nations with lower consumptions of spices per capita showed greater number of COVID-19 cases per million population. This is not surprising as herbs and spices are well-known to boost immunity. Although the precise molecular mechanisms associated with spices and immunity are not completely understood, our findings led us to hypothesize that spice consumption plays a role in our ability to fight COVID-19; however, intensive research is needed to determine the translational value of these findings.

Polyphenol-rich curry made with mixed spices and vegetables benefits glucose homeostasis in Chinese males (Polyspice Study): a dose-response randomized controlled crossover trial.

PURPOSE: To investigate acute effects of two doses of a polyphenol-rich curry made with seven different spices and four base vegetables, eaten with white rice, on 24 h glucose response, postprandial insulinemia, triglyceridemia and 24 h urinary total polyphenol excretion (TPE). METHODS: Randomized, controlled, dose-response crossover trial in healthy, Chinese men [n = 20, mean ± standard deviation (SD) age 23.7 ± 2.30 years, BMI 23.0 ± 2.31 kg/m2] who consumed test meals matched for calories, macronutrients and total vegetables content, consisting either Dose 0 Control (D0C) or Dose 1 Curry (D1C) or Dose 2 Curry (D2C) meal. 24 h glucose concentration was measured using continuous glucose monitoring (CGM), together with postprandial plasma insulin and triglyceride for up to 7 h. Total polyphenol content (TPC) of test meals and urinary TPE were measured using the Folin-Ciocalteu assay. RESULTS: TPC for D0C, D1C and D2C were 130 ± 18, 556 ± 19.7 and 1113 ± 211.6 mg gallic acid equivalent (GAE) per portion served, respectively (p < 0.0001). Compared with D0C meal, we found significant linear dose-response reductions in the 3-h postprandial incremental AUC (iAUC) for CGM glucose of 19% and 32% during D1C and D2C meals respectively (p < 0.05) and non-significant linear dose response reductions in iAUC of insulin (p = 0.089). Notably, we found significant dose-dependent increases in postprandial triglyceride with increasing curry doses (p < 0.01). Significant increases in TPE with increasing curry doses were also observed (p < 0.01). CONCLUSION: Polyphenol-rich curry intake can improve postprandial glucose homeostasis. The longer term effects remain to be established.

Spicy food and self-reported fractures.

BACKGROUND & AIMS: Population-based evidence that suggests health effects of spicy consumptions on fracture was scant. The study aimed to explore the association of spicy food intake with self-reported history of fractures in the Chinese populations. METHODS: Data was drawn from the baseline survey of a large cohort study conducted in China between 2004 and 2008. A total of 512,891 adults (including 302,632 females) were included. Frequency, strength and duration of spicy food consumption were assessed using a survey questionnaire. Fracture history was self-reported based on physician's diagnoses. Multivariate logistic regression models stratified by socio-economic factors, body mass index and other lifestyle factors were performed adjusting for potential confounders. RESULTS: The prevalence of daily spicy food intake was 30.32% in males and 29.90% in females. The adjusted odds ratios for fractures were 1.04 (95% CI: 1.01-1.07) for those who ate spicy food occasionally, 1.10 (95% CI: 1.05-1.16) for those who ate one or two days a week, 1.15 (95% CI: 1.09-1.20) for three to five days a week, and 1.12 (95% CI: 1.07-1.17) for daily consumers, compared to participants who never ate spicy food. Participants who ate weak spicy food (OR: 1.10, 95% CI: 1.14-1.23), moderate spicy food (OR: 1.11, 95% CI: 1.06-1.15) and strong spicy food (OR: 1.18, 95% CI: 1.12-1.25) were more strongly associated with self-reported history of fracture. In addition, the strengths of associations were consistently stronger with the duration of spicy food exposure. In stratified analyses, the strength of such an association appeared stronger in rural areas (OR: 1.14, 95% CI: 1.09-1.20) than urban (OR: 1.09, 95% CI: 1.05-1.12). The correlation was consistently stronger in males than in females. CONCLUSIONS: Among Chinese adults, a positive cross-sectional association between the level of spicy food intake and history of fractures was found in both sexes.

Species richness, cultural importance, and prioritization of wild spices for conservation in the Sudano-Guinean zone of Benin (West Africa).

BACKGROUND: Spices have always been used for their flavor-enhancement characteristics and for their medicinal properties. In Benin, scientific research on spices is scarce, despite their importance in the local population's daily needs. This study investigated the diversity of wild spices and documented the associated traditional knowledge that can be used for their valuation, domestication, and sustainable management in the Sudano-Guinean Zone of Benin. METHODS: Data were collected during field expeditions using semi-structured interviews in ten localities across the three phytodistricts of the zone. Species richness and Shannon's diversity index were estimated using species accumulation curves. Use report (UR), cultural importance, use value (UV) index, and informant consensus factor (Fic) were used to assess traditional knowledge on wild species, their local importance, and informants' agreement among sociolinguistic groups. Priority wild spices were finally identified using an approach combining eight criteria (native status, economic value, ethnobotanical value, global distribution, national distribution, in-situ and ex-situ conservation status, legislation, and threats assessment) in four prioritization methods (point scoring procedure, point scoring procedure with weighting, compound ranking system, and binomial ranking system). RESULTS: A total of 14 species, belonging to 12 genera and 9 families, were inventoried. The most prominent families were Zingiberaceae (21.43%), Annonaceae (21.43%), and Rutaceae (14.29%). More than 200 specific uses were reported, with the Tchabè people holding the greatest level of knowledge (70 uses; UR = 5.70 ± 0.33). The culturally most important spices differed among sociolinguistic groups. Most of the informants agree on the use of the species among (Fic = 0.72-0.98) and across the considered use categories (Fic = 0.88-0.99). The highest UV were registered for Aframomum alboviolaceum (UV = 0.93), Lippia multiflora (UV = 0.76), and Aframomum angustifolium (UV = 0.18). Overall, people perceived wild spices as declining due to agriculture, grazing, and drought. Five species, A. alboviolaceum, L. multiflora, Monodora tenuifolia, Xylopia aethiopica, and Z. zanthoxyloides, were the most prioritized for conservation. CONCLUSIONS: This study provides information relevant for the implementation of conservation and domestication actions of wild spices in Benin. Priority species could be integrated into traditional agroforestry systems (e.g., home gardens). However, for this to be effective, further research should be undertaken on morphological and genetic diversity and propagation methods of priority wild spices.

Dose-Dependent Increase in Unconjugated Cinnamic Acid Concentration in Plasma Following Acute Consumption of Polyphenol Rich Curry in the Polyspice Study.

Spices that are rich in polyphenols are metabolized to a convergent group of phenolic/aromatic acids. We conducted a dose-exposure nutrikinetic study to investigate associations between mixed spices intake and plasma concentrations of selected, unconjugated phenolic/aromatic acids. In a randomized crossover study, 17 Chinese males consumed a curry meal containing 0 g, 6 g, and 12 g of mixed spices. Postprandial blood was drawn up to 7 h at regular intervals and plasma phenolic/aromatic acids were quantified via liquid chromatography tandem mass spectrometry (LC-MS/MS). Cinnamic acid (CNA, p < 0.0001) and phenylacetic acid (PAA, p < 0.0005) concentrations were significantly increased with mixed spices consumption, although none of the other measured phenolic/aromatic acids differ significantly between treatments. CNA displayed a high dose-exposure association (R² > 0.8, p < 0.0001). The adjusted mean area under the plasma concentration-time curve until 7 h (AUC0⁻7 h) for CNA during the 3 increasing doses were 8.4 ± 3.4, 376.1 ± 104.7 and 875.7 ± 291.9 nM.h respectively. Plasma CNA concentration may be used as a biomarker of spice intake.

Pleasantness, familiarity, and identification of spice odors are interrelated and enhanced by consumption of herbs and food neophilia.

The primary dimension of odor is pleasantness, which is associated with a multitude of factors. We investigated how the pleasantness, familiarity, and identification of spice odors were associated with each other and with the use of the respective spice, overall use of herbs, and level of food neophobia. A total of 126 adults (93 women, 33 men; age 25-61 years, mean 39 years) rated the odors from 12 spices (oregano, anise, rosemary, mint, caraway, sage, thyme, cinnamon, fennel, marjoram, garlic, and clove) for pleasantness and familiarity, and completed a multiple-choice odor identification. Data on the use of specific spices, overall use of herbs, and Food Neophobia Scale score were collected using an online questionnaire. Familiar odors were mostly rated as pleasant (except garlic), whereas unfamiliar odors were rated as neutral (r = 0.63). We observed consistent and often significant trends that suggested the odor pleasantness and familiarity were positively associated with the correct odor identification, consumption of the respective spice, overall use of herbs, and food neophilia. Our results suggest that knowledge acquisition through repetitive exposure to spice odor with active attention may gradually increase the odor pleasantness within the framework set by the chemical characteristics of the aroma compound.

A novel method to analyze social transmission in chronologically sequenced assemblages, implemented on cultural inheritance of the art of cooking.

Here we present an analytical technique for the measurement and evaluation of changes in chronologically sequenced assemblages. To illustrate the method, we studied the cultural evolution of European cooking as revealed in seven cook books dispersed over the past 800 years. We investigated if changes in the set of commonly used ingredients were mainly gradual or subject to fashion fluctuations. Applying our method to the data from the cook books revealed that overall, there is a clear continuity in cooking over the ages--cooking is knowledge that is passed down through generations, not something (re-)invented by each generation on its own. Looking at three main categories of ingredients separately (spices, animal products and vegetables), however, disclosed that all ingredients do not change according to the same pattern. While choice of animal products was very conservative, changing completely sequentially, changes in the choices of spices, but also of vegetables, were more unbounded. We hypothesize that this may be due a combination of fashion fluctuations and changes in availability due to contact with the Americas during our study time period. The presented method is also usable on other assemblage type data, and can thus be of utility for analyzing sequential archaeological data from the same area or other similarly organized material.

Spicy food consumption is associated with adiposity measures among half a million Chinese people: the China Kadoorie Biobank study.

BACKGROUND: Few animal experiments and volunteer-based intervention studies have showed a controversial effect of spicy foods on weight management; however, information is scant on the association between spicy food intake and obesity. This study aims to examine the impact of spicy food on quantitative adiposity measures in the Chinese population; a population with a low prevalence of general obesity, but a high prevalence of central obesity. METHODS: A total of 434,556 adults (255,094 females), aged 30-79 years, were included from the China Kadoorie Biobank (CKB) study. Information on spicy food intake was obtained using a questionnaire survey. Body mass index (BMI), percentage body fat (BF%), waist circumference (WC), and WC/height ratio (WHtR) were analyzed as continuous variables. RESULTS: The prevalence of daily spicy food eating was 30.4% in males and 30.0% in females, with dramatically geographic diversity (ranging from 99.4% in Hunan to 2.7% in Zhejiang). The covariates-adjusted BMI, BF%, WC, and WHtR significantly increased with increasing frequency, strength, and duration of spicy food eating regardless of gender (p < 0.001). Among regular spicy food consumers, strength of spicy food eating showed significant and positive association with all adiposity measures in both genders (except for BF% in males). Compared with non-consumers, daily spicy food eating was significantly associated with an increase of 0.44 and 0.51 of BMI (kg/m2), 0.79 and 1.01 of BF%, 1.4 and 1.0 of WC (cm), and 0.008 and 0.006 of WHtR in males and females, respectively. In stratified analyses of 18 consecutive BMI subgroups, a significantly increasing trend in the effect of daily spicy food eating on WC and WHtR with increasing BMI was noted in males; whereas a decreasing trend was seen in females. CONCLUSIONS: The data indicate that spicy food intake is a risk factor for obesity in Chinese adult population, especially for central obesity in males. Further studies are needed to elucidate the mechanisms underlying this association.

Análise sensorial de feijões de restaurantes comerciais com substituição do sal por ervas e especiarias / Sensory analysis on beans in commercial restaurants with replacement of salt by herbs and spices

Eating in restaurants is becoming a habit, especially in bigger cities. Buffet restaurants which sell food by weight offer beans every day, as the consumption of beans and rice is a cultural habit in Brazil. Researches report that 80% of the sodium consumed by individuals comes from eatingin restaurants and ready-to-eat food and that the high consumption of sodium is the main cause of hypertension. In this context, the objective of this study was to carry out a sensory analysis on the beans served in five buffet restaurants, located downtown Chapecó - SC. Three different preparations of beans for each restaurant were considered: a sample prepared with 100% of the salt indicated in the technical datasheet of the restaurant; another sample using 50% of salt indicated; and a third sample with 25%of salt indicated in the datasheet. In these two latter cases, the seasoning has been replaced with herbs and spices. During five days, tests on these three preparations of beans were performed with a total of 185 untrained tasters using the nine-point structured scale, anchored with verbal terms. The data regarding acceptance were subjected to analysis of variance (ANOVA) and to Tukey's test, with a significance level (p < 0,05). The results show that the tasters preferred the samples which contained 100% and rejected the samples which contained 50% and 25% of seasoning. With the exception of restaurant A, which showed an average acceptance rate between 6.47 and 6.03 for all kinds of preparations. Public health actions should be prioritized in order to promote healthy food in restaurants for the maintenance of health and prevention of diseases.

La alimentación fuera de casa es un hábito cada vez más arraigado, principalmente en los grandes centros urbanos. Los restaurantes que comercializan comida al kilo ofrecen frijoles diariamente, pues su consumo junto con arroz hace parte de la cultura del brasileño. Los estudios relatan por un lado que 80% del consumo de sodio de una persona proviene de la alimentación fuera de casa y de alimentos prontos para consumo y por otro, que el consumo elevado de sodio es la principal causa de la hipertensión. En este contexto, el objetivo del trabajo fue realizar análisis sensorial de losfrijoles servidos en cinco restaurantes al kilo, localizados en el centro de Chapecó (Santa Catarina, Brasil). Fueron consideradas tres preparaciones de frijoles para cada restaurante: una preparada con 100% de la sal indicada en la ficha técnica del restaurante; otra con utilización de 50% de la indicación; y una tercera con 25%. En los dos últimos casos, la sal fue sustituida por hierbas aromáticas y especias. Durante cinco días, fueron realizados ensayos con las tres preparaciones de frijoles con un total de 185 probadores no entrenados, utilizándose una escala estructurada de nueve puntos, anclada en expresiones literales. Los datos referentes a la aceptación fueron sometidos a un análisis de varianza (ANOVA) y a la prueba de Tukey, con nivel de significancia (p < 0,05). El resultado muestra que los probadores se inclinaron por las muestras que contenían 100% de sal y rechazaron las que contenían 50 y 25% del condimento. La excepción fue el Restaurante A que presentó medias de aceptación entre 6,47 y 6,03 para todas las preparaciones. Acciones de salud pública deben ser priorizadas con el objetivo de promover una alimentación saludable en establecimientos comerciales, para mantención de la salud y prevención de enfermedades.

A alimentação realizada fora de casa está se tornando um hábito, principalmente nos grandes centros.

Nesse contexto, o objetivo do trabalho foi realizar análise sensorial dos feijões servidos em cinco restaurantes por peso, localizados no centro de Chapecó (SC). Foram consideradas três preparações de feijão para cada restaurante: uma amostra preparada com 100% do sal indicado na ficha técnica do restaurante; outra com a utilização de 50% do sal indicado; e uma terceira com 25% do sal. Nesses dois últimos casos, o tempero foi substituído por ervas aromáticas e especiarias. Durante cinco dias, foram realizados testes desses três tipos de feijão com um total de 185 provadores não treinados, utilizando-se a escala estruturada de nove pontos, ancorada com termos verbais. Os dados referentes à aceitação foram submetidos à análise de variância (ANOVA) e ao teste de Tukey, com nível de significância (p < 0,05).O resultado mostra que houve preferência dos provadores pelas amostras que continham 100% e rejeição pelas amostras que continham 50 e 25% do tempero. Com exceção do Restaurante A que apresentou médias de aceitação entre 6,47 e 6,03 para todas as preparações. Ações de saúde pública devem ser priorizadas no intuito de promover alimentação saudável em estabelecimentos comerciais, para manutenção da saúde e prevenção de doenças.

[Preferences of the powdered spices choice to the meal by professionally working persons in relation to the innovative changes in their manufacturing]. / Preferencje wyboru przypraw sypkich do potraw przez osoby pracujace zawodowo z uwzglednieniem innowacyjnych zmian w ich produkcji.

The objective of this study was to evaluate preferences and frequency choice of commercially available powdered spices, applied to the dishes prepared at home by professionally working persons as well as factors which determine the acceptance of innovative changes in relation to the number and type of components used for their manufacturing. It was shown that above 80% mixtures of spices contained except vegetable spices also other flavourings, spice-products and functional additives but mostly monosodium glutamate (MSG) and sodium chloride. The respondents mostly accepted multicomponent powdered spices, manufactured with the application of new technologies which permitted creation original tastes and next their health-promoting role as well as convenience in use however, without changes in recipe. The women declared that to the dishes prepared at home usually applied herb spices. Conversely, the men mostly liked and often chose spices with savoury and distinctive taste and most willingly multicomponent ones which were suitable for flavour improvement of many dishes.

Diferentes condimentos vegetais: avaliação sensorial e de atividade antibacteriana em preparação alimentar com frango cozido / Different spice plants: sensorial evaluation and antibacterial activity in chicken broth

A partir da atividade antibacteriana in vitro, predeterminada em doze plantas com indicativo etnográfico condimentar, testou-se este atributo in loco no modelo caldo com frango cozido. Primeiramente, procedeu-se ao treinamento de 10 avaliadores, segundo a legislação vigente quanto ao Consentimento Livre e Esclarecido, oportunizando conhecimentos prévios sobre as plantas salsa (Petroselinum sativum), manjerona branca (Origanum X aplii), manjerona preta (Origanum majorana), manjericão (Ocimum basilicum), sálvia (Salvia officinalis), tomilho (Thymus vulgaris), anis verde (Ocimum selloi), alfavaca (Ocimum gratissimum), alho nirá (Allium tuberosum), alho poró (Allium porrum), cúrcuma (Curcuma longa) e pimenta dedo-de-moça (Capsicum baccatum). Realizou-se, através da adição individualizada desses condimentos ao caldo com frango cozido, um Teste de Aceitação tipo escala hedônica, selecionando, dentre os doze condimentos, quatro deles que se destacaram sensorialmente, a pimenta dedo-de-moça, o alho nirá, o alho poró e o tomilho. Foi feito, então, um Teste de Aceitação de concentrações denominadas pequena, média e grande destes quatro condimentos, para determinação da intensidade sensorialmente melhor aceita. As quantidades eleitas (0,5 g de pimenta dedo-de-moça, 15 g de alho nirá, 15 g de alho poró e 5 g de tomilho) foram acrescidas ao caldo com frango cozido, sendo estes desafiados frente a Escherichia coli (ATCC 11229) em concentração final de 10 UFC mL-1, limite tolerado pela legislação, tendo como grupo-controle o caldo com frango cozido sem condimentos. O crescimento bacteriano foi aferido a cada duas horas após a inoculação, até completar 24 horas de confronto, utilizando-se meio seletivo para coliformes termo-resistentes e incubação constante a 25ºC em DBO, sendo atribuídos valores arbitrários às variações logarítmicas de crescimento. Comparados ao controle, todos os tratamentos condimentados apresentaram, individualmente, atividade antibacteriana significativa, mesmo que sem significância quando comparados entre si. Contudo, em relação ao tempo de início da atividade antibacteriana, destacou-se a pimenta dedo-de-moça, enquanto que, em relação ao prolongamento dessa ação no tempo, destacou-se o alho nirá. As 12 plantas condimentares em estudo tiveram atestada a sensorialidade, sendo que as quatro plantas com destaque tiveram a atividade anti-coliforme termo-resistente comprovada in loco. Diferentes condimentos vegetais foram capazes de fornecer qualificação sensorial e sanitária em caldo com frango cozido, em condições domésticas de manuseio.

Based on the in vitro antibacterial activity predetermined for 12 spice plants with ethnographic indicator, this feature was tested in loco in the model cooked chicken broth. First, ten evaluators were trained, according to the current legislation for Free and Informed Consent, providing previous knowledge about the plants parsley (Petroselinum sativum), marjoram (Origanum X aplii and Origanum majorana), basil (Ocimum basilicum), common sage (Salvia officinalis), thyme (Thymus vulgaris), anis-like spice (Ocimum selloi), african basilicum (Ocimum gratissimum), nirá garlic (Allium tuberosum), leek (Allium porrum), turmeric (Curcuma longa) and "dedo-de-moça" chili (Capsicum baccatum). Those spices were individually added to the chicken broth to perform a Hedonic Scale-like Acceptance Test, selecting four of the twelve spices that had higher sensory acceptance, "dedo-de-moça" chili, nirá garlic, leek and thyme. A new Acceptance Test was then performed using low, medium and high concentrations of those four spices to establish the most acceptable sensory intensities. The elected quantities (0.5 g "dedo-de-moça" chili, 15 g nirá garlic, 15 g leek and 5 g thyme) were added to the chicken broth, then challenged with Escherichia coli (ATCC 11229) at a final 10 concentration of CFU/mL, the tolerated limit according to legislation. The control group was chicken broth without spices. The bacterial growth was measured at every two hours after the inoculation until 24 hours of confront were completed, using a selective medium for thermo-resistant coliforms, under constant incubation at 25ºC in DBO. Arbitrary values were assigned to the logarithmic growth variations. Compared to the control group, all the spiced treatments individually presented significant antibacterial activity, although the latter was not significant when treatments were compared with each other. However, as regards the antibacterial activity starting time, "dedo-de-moça" chili had the best results, whereas nirá garlic had the best results as regard the extension of this activity time. The 12 studied spice plants had their sensorial characteristics attested, and the four plants that had the best results had proved in loco anti-thermo-resistant coliform activity. Different spice plants were capable of providing sensory and sanitary qualification in chicken broth, under domestic conditions of manipulation.

The total antioxidant content of more than 3100 foods, beverages, spices, herbs and supplements used worldwide.

BACKGROUND: A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies. METHODS: We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name) were registered for each individual food sample and constitute the Antioxidant Food Table. RESULTS: The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values. CONCLUSIONS: This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non-plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies. The present antioxidant database is therefore an essential research tool to further elucidate the potential health effects of phytochemical antioxidants in diet.

The town of Cabar, Croatia, a high risk area for multiple sclerosis--analytic epidemiology of dietary factors.

Multiple sclerosis (MS) is demyelization disease of central nervous system of unidentified causes. Analytic epidemiological research of 19 patients, clinically approved cases of MS and 25 controls, autochthonic inhabitants of town of Cabar, Croatia, the high-risk zone for the disease, was made. The research plan included case-control investigation--the "door to door" questionnaire--about nutrition habits. An odds ratio (OR) was calculated for all the factors which were more frequently found in the patients than in the controls, and vice versa. The variables that were connected with significant risk for MS in the town of Cabar included: alcohol consumption (p = 0.05), animal fats/dried meat products consumption (p = 0.007), nitrate salting (p = 0.03), strong spices (p = 0.007), mixed bread (p = 0.002), oat and oat products consumption (p = 0.0075). No connection was found with regular consumption of vegetables and fruit (p = 0.009), blue fresh fish (p = 0.028), other fresh fish (p = 0.03), freshwater fish (p = 0.002), canned fish (p = 0.004), dormouse meat (p = 0.007), air-dried meat products (p = 0.004) and using the water from water supply (p = 0.011). In the town of Cabar nutritional customs, primarily food rich in animal fats, alcohol-abuse, and oat consumption could have an influence on MS pathogenesis in genetically inclined individuals.

Adaptive ingredients against food spoilage in Japanese cuisine.

Billing and Sherman proposed the antimicrobial hypothesis to explain the worldwide spice use pattern. The present study explored whether two antimicrobial ingredients (i.e. spices and vinegar) are used in ways consistent with the antimicrobial hypothesis. Four specific predictions were tested: meat-based recipes would call for more spices/vinegar than vegetable-based recipes; summer recipes would call for more spices/vinegar than winter recipes; recipes in hotter regions would call for more spices/vinegar; and recipes including unheated ingredients would call for more spices/vinegar. Spice/vinegar use patterns were compiled from two types of traditional Japanese cookbooks. Dataset I included recipes provided by elderly Japanese housewives. Dataset II included recipes provided by experts in traditional Japanese foods. The analyses of Dataset I revealed that the vinegar use pattern conformed to the predictions. In contrast, analyses of Dataset II generally supported the predictions in terms of spices, but not vinegar.

Relative importance of risk factors in bladder carcinogenesis: some new results about Mediterranean habits.

In the Mediterranean region of France where bladder cancer mortality and incidence are high, a case-control study with 219 male incident cases and 794 randomized, male population-controls was carried out in 1987-89 to investigate bladder cancer risk factors and more specifically, regional factors. A stepwise logistic regression was applied to the data. This investigation confirms the role of tobacco and of certain occupational exposures in bladder carcinogenesis. There was a significant dose-response relationship with lifelong coffee drinking and alcohol consumption; however the risk estimates were only significantly elevated for the heaviest drinkers. The intake of saccharin was not associated with risk of bladder cancer. Infrequent consumption of carrots, spinach, and marrows conferred an increased risk, suggesting a protective effect of vitamin A. Finally, this investigation results in some new hypotheses. The study of residences and birthplaces has revealed a lower risk for those who have lived in a non-Mediterranean area and a higher risk for those born in a Mediterranean area. These features might be explained by some Mediterranean dietary habits, such as a high consumption of spices (odds ratio = 3.64, 95 percent confidence interval = 2.21-5.98).
