          Abstract

          Abstract Introduction: information about changes in food and energy supply, macronutrient and micronutrient availability by processing level is required to understand the nutritional transition in Mexican society. Objective: to describe the food, energy, and nutrient supply in Mexican households from 1984 to 2018. Methods: five waves of a Mexican cross-sectional survey were analyzed to identify changes in food, energy, and nutrient supplies in households. Food groups were created using the NOVA classification. The content of energy and nutrients was estimated using Mexican and U.S. databases. The education and income interaction with energy and nutritional supply was analyzed. Results: in this period, the supply of fresh and processed fruits and vegetables, processed meat and dairy, fish and seafood, prepared food, and ultra-processed food and drinks increased, whereas unprocessed or minimally processed (UMP) cereals and tubers, legumes, meat, dairy, eggs, and all processed culinary ingredients decreased. These changes have implied a higher supply of protein, total fat, cholesterol, vitamins A and C, calcium and sodium. Total energy, energy density, carbohydrates, and magnesium and potassium density decreased. Across waves, UMP and processed cereals were the main supply for energy, carbohydrates, fiber, iron and potassium. Dairy was the main supply of saturated fat. UMP and processed cereals were the main source of sodium in 1984, whereas ultra-processed cereals were the main source of sodium in 2018. Conclusions: although UMP foods remain the main group in most Mexican households, their supply has decreased over the years, whereas the supply of ultra-processed foods has increased.

          Resumen Introducción: se requiere información sobre los cambios de la disponibilidad de alimentos, energía y nutrientes, por nivel de procesamiento, para entender la transición nutricional en México. Objetivo: describir la disponibilidad de alimentos, energía y nutrientes en los hogares mexicanos de 1984 a 2018. Métodos: se crearon grupos usando la clasificación NOVA. El contenido de energía y nutrientes se estimó usando bases de datos mexicanas y estadounidenses. Se analizó la interacción de la educación y el ingreso con la disponibilidad de energía y nutrientes. Resultados: en este periodo aumentó la disponibilidad de verduras naturales y procesadas, carnes y lácteos procesados, pescados y mariscos, comida preparada y comida y bebida ultraprocesada, mientras que los cereales sin procesar o mínimamente procesados (SPMP), las leguminosas, las carnes, los lácteos, los huevos y los ingredientes culinarios procesados disminuyeron. Estos cambios implican una mayor disponibilidad de proteína, grasa total, colesterol, vitamina A y C, calcio y sodio. La energía total, la densidad energética, los carbohidratos y la densidad de magnesio y potasio disminuyeron. A lo largo el tiempo, los cereales SPMP y procesados fueron la principal fuente de energía, carbohidratos, fibra, hierro y potasio. Los lácteos fueron la principal fuente de grasas saturadas. Los cereales SPMP y procesados fueron la principal fuente de sodio en 1984, mientras que los cereales ultraprocesados lo fueron en el 2018. Conclusiones: aunque los alimentos SPMP siguen siendo el grupo más disponible en los hogares, su disponibilidad ha disminuido a lo largo de los años, mientras que la de los ultraprocesados ha aumentado.

          Fruit, vegetables, and cancer prevention: a review of the epidemiological evidence.

          Approximately 200 studies that examined the relationship between fruit and vegetable intake and cancers of the lung, colon, breast, cervix, esophagus, oral cavity, stomach, bladder, pancreas, and ovary are reviewed. A statistically significant protective effect of fruit and vegetable consumption was found in 128 of 156 dietary studies in which results were expressed in terms of relative risk. For most cancer sites, persons with low fruit and vegetable intake (at least the lower one-fourth of the population) experience about twice the risk of cancer compared with those with high intake, even after control for potentially confounding factors. For lung cancer, significant protection was found in 24 of 25 studies after control for smoking in most instances. Fruits, in particular, were significantly protective in cancers of the esophagus, oral cavity, and larynx, for which 28 of 29 studies were significant. Strong evidence of a protective effect of fruit and vegetable consumption was seen in cancers of the pancreas and stomach (26 of 30 studies), as well as in colorectal and bladder cancers (23 of 38 studies). For cancers of the cervix, ovary, and endometrium, a significant protective effect was shown in 11 of 13 studies, and for breast cancer a protective effect was found to be strong and consistent in a meta analysis. It would appear that major public health benefits could be achieved by substantially increasing consumption of these foods.

            Health benefits of fruits and vegetables.

            Fruits and vegetables are universally promoted as healthy. The Dietary Guidelines for Americans 2010 recommend you make one-half of your plate fruits and vegetables. Myplate.gov also supports that one-half the plate should be fruits and vegetables. Fruits and vegetables include a diverse group of plant foods that vary greatly in content of energy and nutrients. Additionally, fruits and vegetables supply dietary fiber, and fiber intake is linked to lower incidence of cardiovascular disease and obesity. Fruits and vegetables also supply vitamins and minerals to the diet and are sources of phytochemicals that function as antioxidants, phytoestrogens, and antiinflammatory agents and through other protective mechanisms. In this review, we describe the existing dietary guidance on intake of fruits and vegetables. We also review attempts to characterize fruits and vegetables into groups based on similar chemical structures and functions. Differences among fruits and vegetables in nutrient composition are detailed. We summarize the epidemiological and clinical studies on the health benefits of fruits and vegetables. Finally, we discuss the role of fiber in fruits and vegetables in disease prevention.
