Food Sustainability Knowledge, Attitudes, and Dietary Habits among Students and Professionals of the Health Sciences.

The importance of a sustainable diet is an emerging concept within sustainable food systems. Food systems emit 30% of greenhouse gases, which needs to change. A cross-sectional study was carried out to determine the knowledge, attitudes, and habits of students and professionals in the health sciences regarding a sustainable diet, comparing these to the Spanish population. We further aimed to analyse the consistency between the knowledge and attitudes of these individuals and their dietary habits and analyse the consumption of different food groups that are typical of a sustainable diet. A survey was completed by a total of 415 participants, both university students in the health sciences and health professionals. These two groups were more knowledgeable of sustainable diets than the general population, although certain concepts are unfamiliar to both populations. A positive attitude towards sustainable food habits was also observed among the population studied. The health sector reported having better eating habits than the overall population. A significant positive correlation was observed between higher fruit and vegetable consumption and deeper knowledge and more favourable attitudes. People with less knowledge and worse attitudes reported consuming more red and processed meat. The findings of this study could inform targeted interventions for health professionals given the need to promote a healthy diet but also a healthy and sustainable diet for planetary health.

Obesidad y cáncer: «las amistades peligrosas» / Obesity and cancer: «Dangerous friendship»

Obesidad y cáncer son 2 problemas sanitarios de primera magnitud en España. La obesidad afecta al 23-28% de la población adulta española, y el sobrepeso y la obesidad abdominal al 39 y 36%, respectivamente. Es bien conocida la relación entre obesidad y diabetes mellitus tipo 2, hipertensión arterial, dislipidemia, y apnea obstructiva del sueño. Menos conocida es en cambio la asociación con el cáncer, porque la evidencia es más reciente. Numerosos estudios prospectivos han demostrado en los últimos años, con un alto grado de evidencia científica, una asociación clara entre la obesidad y los cánceres de colon y recto, mama en mujeres pos-menopáusicas, endometrio, riñón, esófago y páncreas. Esta asociación es también probable con los tumores de hígado, vesícula biliar, cardias, tiroides, y hematológicos, para los que se requieren más estudios. Un mejor conocimiento de la relación entre obesidad y cáncer puede permitir mejorar las estrategias de prevención del cáncer, así como una más eficiente detección precoz, y un tratamiento más adecuado de la obesidad y el sobrepeso. Aunque los mecanismos por los cuales la obesidad induce los distintos tipos de cánceres no son suficientemente conocidos, evitar el sobrepeso y la obesidad es hoy una de las medidas más efectivas para reducir el riesgo de cáncer, por lo que es necesario concienciar a la población general sobre uno de los mayores peligros que entraña la actual epidemia de obesidad (AU)

Obesity and cancer are one of the most important health problems is Spain. Between 23 and 28% of the adult population in Spain are obese, 39% are overweight and 36% have abdominal obesity. The association between obesity and type 2 diabetes mellitus, hypertension, dyslipidemia and sleep obstructive apnea is well known. On the contrary, the association between obesity and cancer is less known, because the recent evidence on it. Several prospective studies have shown during the last years the strong relationship between obesity and cancer of colon, breast in post-menopausal women, endometrial, kidney and pancreas as well as esophageal adenocarcinoma. Furthermore there is recent evidence showing that liver, gallbladder, thyroid and ovarian cancer as well as leukemia, multiple myeloma and Hodgkin lymphomas are probably associated with obesity, yet more studies are needed. A better knowledge of the relation between cancer and obesity will allow improving the prevention strategies against cancer, a more efficient early detection, and a more suitable treatment of obesity and overweight. Although the mechanisms of carcinogenesis of obesity are not well established, avoiding overweight and obesity are considered one of the best approaches to reduce the risk of cancer. Therefore the general population must be aware that cancer is one of the most important hazards associated with the current obesity epidemic in our society (AU)
