Some data suggest a beneficial effect of dairy consumption on the risk of childhood obesity, but the long-term association is unclear. This systematic review, based on prospective cohort studies, confirms the inverse association between dairy consumption and the risk of overweight/obesity in children and adolescents.

More than 46.000 children and adolescents

Obesity in childhood and adolescence has become a major health disorder, and identifying modifiable risk factors, such as food habits, with strong consistency is necessary. For their purpose, Lu et al. identified eligible studies by extensive research, using the two main resources (PubMed and EMBASE) through March 2015. They completed the selection via Google Scholar and references from relevant articles. This lead to a particularly large sample of 46 011 children and adolescents from ten studies. The average period of follow-up was 3 years.

Less childhood obesity for each serving of dairy

The results show that dairy consumption is inversely associated with the likelihood of being overweight or obese: children in the highest intake group for dairy consumption were 38% less likely to have overweight/obesity, as compared with those from the lowest group of dairy consumption. The authors calculated that for each serving/day increment in dairy consumption, the percentage of body fat was reduced by 0.65%. In the same way, the risk of overweight/obesity was 13% lower for each increment of dairy serving. This clearly suggests an inverse association between dairy products and overweight/obesity, and the authors emphasis the need to examine the type of dairy in further studies.

Breakfast ideas for kids by Dietitian Erika Ochoa

It’s back to school season! Dietitian Erika Ochoa shares her expertise and breakfast ideas for kids.

What is according to you the most important meal when kids go back to school? And why?

All three meals are important. Skipping one or more may be counterproductive for a child’s development and performance at school. Nevertheless, breaking the long lasting night fast seems quite important. It helps kids to have higher and longer attention span at school and, thus, better performance at different tasks.

The longest fast of the day happens at night. When kids wake up their glucose reserve has ran out. Their bodies need to make use of fat and muscle mass so as to obtain energy. In order to have enough energy for school (which involves paying attention, solving difficult math problems, learning to read and write, memorizing, among other cognitive activities) children’s brains need to have glucose—since it is its favorite fuel—and the only way to get is by having breakfast.

Breakfast foods can be high in energy but poor in other nutrients, i.e. a sweet biscuit or some kind of pastry. This type of foods may break the fast and give an energy boost to children, however, they will be feeling hungry on the long run (or maybe not so long) and without enough energy needed for concentration at school.

Having a hearty and nutritious breakfast is essential. When we think of a hearty breakfast it may seem a four-time-meal or a buffet; however, what I want you to think of is a meal which contains all food groups: some fruit or vegetable (not juices), some protein (from legumes to animal products), and some cereal (think whole-grain instead of ready-to-eat breakfast cereals). A breakfast that includes all of these foods is hearty enough to get your kid running and thinking until lunch time, and avoid getting distracted by hunger.

 

How can you integrate yogurt in that meal? Do you have breakfast ideas for kids?

Yogurt is a very flexible food: you can use it for breakfast, in a salad, or even in desserts. To be honest, nowadays it is very hard to find time to prepare and eat hearty and nutritious breakfasts so we need to use foods that are quite handy to fulfill the recommendation.
I suggest including yogurt at breakfast as a protein-rich food, high in calcium, and with live cultures that are always helpful for your microbiota (more information on the Gut Microbiota for Health initiative’s website).

Breakfast ideas for kids that include yogurt? Children can eat yogurt on the go (drink it up on the way to school), just make it complete by having a fruit (banana or an apple) and some granola or oatmeal. Too complicated? You can make it a smoothie: 1 yogurt, some fruit and a few tablespoons of uncooked oatmeal.

Nowadays, you may find many cold-overnight-oatmeal recipes all over the net (check out Pinterest). Overnight-oatmeal is very useful for our hectic lives since you prepare it at night and it is ready to eat in the morning. Children love it because it can be done with lots of different fruits like raspberries, cranberries, banana, mango, peach, etc. You can make it even tastier if you add their favorite yogurt instead of milk.

If you rather have your kid sitting down at the table, have some fruit topped with yogurt, nuts, and wheat bran. Your child may find yoghurt more tempting than milk, thus, you can offer some toast with peanut butter and banana and yogurt for a drink.

As you can see yogurt is quite adaptable to different meals, recipes, and more importantly, to children’s likings.

 

What are your tips to mums to include yogurt as part of a healthy diet?

Throughout the day children have different cravings. Many times, they get candy and sugary-drinks that are energy-dense but quite far from being high in different nutrients. Yogurt is always a better idea. It may have sugar (usually a lot less than what a soda has) but it offers a variety of nutrients (protein, calcium, phosphorous, vitamin D, among others) that are needed and suitable for children.

Yogurt comes in a variety of flavors and presentations that may suit a child’s likings and preferences. If your kid is not fond of yogurt, maybe he has not tried enough.

¡Llegó el Regreso a Clases! la Nutrióloga Erika Ochoa comparte su experiencia y da ideas para el desayuno de los niños.

¿Cuál es para ti la comida más importante cuando los niños regresan a la escuela? ¿Por qué?

Las tres comidas principales son igual de importantes, saltarse o no realizar alguna de ellas, puede ser contraproducente para el desarrollo y rendimiento escolar de los niños. Sin embargo, romper el ayuno provocado por las horas de sueño durante la mañana, parece realmente importante para que los niños puedan tener mayor y mejor atención en la escuela, así como mejor desempeño en sus diferentes actividades.

El ayuno más prolongado sucede durante la noche. Cuando los niños despiertan, su reserva de glucosa se ha agotado, y sus cuerpos obtienen la energía necesaria de su masa grasa y del músculo. Con la finalidad de tener energía para la escuela (lo que involucra que pongan atención, que resuelvan problemas de matemáticas, que aprendan a leer y escribir, memorizar, entre otras actividades cognitivas), los cerebros de los niños necesitan glucosa, por ser su fuente favorita de energía, y su única manera de obtenerlo es a través del desayuno.

Los alimentos incluidos en el desayuno pueden ser altos en energía y bajos en otros nutrimentos, como por ejemplo, las galletas o pastelitos. Este tipo de alimentos pueden romper el ayuno y proveer de una gran cantidad de energía a los niños, sin embargo, es probable que en poco tiempo, sientan hambre otra vez y no cuenten con la energía necesaria para concentrarse en la escuela.

Es esencial tener promover que los niños tengan un desayuno abundante y nutritivo. Por desayuno abundante, no debemos pensar en una comida de cuatro tiempos o un buffet, sino en un desayuno que contenga todos los grupos de alimentos: 1) Frutas y Verduras (no jugos), 2) Proteína (leguminosas o alimentos de origen animal) y 3) Cereales (preferir los integrales en vez de aquellos preparados, listos para comer). El desayuno puede incluir todos los grupos de alimentos y ayudar así, a que los niños puedan correr y pensar hasta la hora del lunch, evitando así que se distraigan por tener hambre.

 

¿Cómo puedes incluir el Yoghurt como parte del desayuno o del lunch?

El yoghurt es un alimento muy práctico y versátil, que puede ser incluido en el desayuno, en una ensalada o incluso como postre. Para ser sincera, hoy en día es muy difícil tener tiempo para preparar un desayuno abundante y nutritivo, por lo que necesitamos utilizar alimentos prácticos que nos permitan cubrir con esta recomendación. Recomiendo la inclusión de yoghurt como parte del desayuno, como un alimento alto en proteínas, calcio y cultivos lácticos que siempre son útiles para el equilibrio de la microbiota.

Los niños pueden consumir yoghurt en su camino a la escuela, completarlo con el consumo de una fruta (plátano o manzana por ejemplo) y agregarle granola o avena. ¿Muy complicado? Puedes prepararlo como un smoothie: 1 yoghurt + 1 pieza de fruta + 2 cucharaditas de avena cruda.

Hoy en día, puedes encontrar diversas recetas de avena para preparar durante la noche y conservar en frío para disfrutar por la mañana (puedes revisar en Pinterest). Estas recetas pueden ser muy útiles para nuestras vidas agitadas y una excelente opción para los niños porque se puede preparar con diferentes frutas como frambuesas, arándanos, plátano, mango y durazno, entre otros. Se pueden hacer recetas más ricas si se añade yoghurt en sustitución de la leche.

Si el niño ya está sentado en la mesa, le puedes ofrecer yoghurt combinado con fruta, nueces y salvado de trigo. Los niños pueden sentirse más atraídos por el yoghurt que por la leche, por lo tanto, puedes ofrecerles pan tostado con crema de cacahuate y plátano, acompañados de un yoghurt bebible.

Como puedes ver, el yoghurt se adapta a diferentes comidas, recetas y sobretodo, a los gustos de los niños.

 

¿Cuáles serían tus recomendaciones para que las mamas incluyan el yoghurt como parte de una alimentación saludable?

Durante el día, los niños pueden tener diferentes antojos. Muchas veces, ellos elijen dulces o refrescos que son altos en energía pero bajos en otros nutrimentos. El yoghurt puede ser siempre una mejor elección. Es cierto que puede contener azúcar (pero definitivamente menor cantidad que un refresco) y ofrece una variedad de nutrimentos, entre los que se incluyen, proteínas, calcio, fósforo y vitamina D, necesarios para el desarrollo de los niños.

El yoghurt ofrece una variedad de sabores y presentaciones que pueden satisfacer los diferentes gustos y preferencias de los niños. Si a un niño no le gusta el yoghurt, tal vez no ha probado lo suficiente.

Previous research has shown that nutrition is associated with academic performance in children and adolescents. Here, Nyaradi et al. investigated the associations between early diet and academic performance during childhood.

Academic performance at 10 and 12 year

The academic performance in childhood can affect future career and income. It is also associated with better health behaviors and outcomes, and therefore, important for public health considerations. This work investigated diet quality among 2287 participants in the Western Australian Pregnancy Cohort (Raine) Study at the one-, two- and three-year follow-ups. They looked at the association between diet scores and the Western Australian Literacy and Numeracy Assessment (WALNA) data from grades five (age 10) and seven (age 12).

Dairy and fruits associated with better performances

The results of this investigation show that a better quality diet score at the age of one year was associated with better performances at both grades, five and seven. The authors found significantly higher scores in mathematics, reading, writing and spelling. A better diet quality over two years was associated with higher academic scores for mathematics, writing and spelling at grade seven.

When looking in more detail, they found that a higher dairy consumption at the age of one, two and three year were associated with higher academic scores at all ages. Higher fruit consumption at age one was also associated with better performances at 10 and 12 year. The authors concluded that the quality of early diet may predict later academic achievement.

It is known that low birth weight (LBW) affects infant mortality, morbidity and the likelihood of chronic and clinical disease in later life, such as diabetes, coronary heart disease, and increased all-cause cardiovascular mortality. In this article, David Clarck reviews some of the literature on this subject, with emphasis on maternal intake of dairy products. Evidence suggests that maternal milk and yogurt consumption may contribute to a better birth weight.

20 million births every year are classified as low birth weight

Globally, there are approximately 20 million births every year that are classified as LBW (birth weight of less than 2.5 kg). LBW infants are frequently stunted and if so, the girls have a higher probability of becoming stunted mothers, giving place to a vicious cycle: stunted, undernourished, young mothers have a high risk of delivering LBW infants. Infants of LBW, if also stunted, have great difficulty with catch-up growth and remain small for age. LBW is influenced by a combination of the duration of gestation and intrauterine growth rates.

Whey protein may be a contributing factor to birth weight

Clarck’s review shows a positive association between maternal dairy product intake and birth weight, and suggests particular effects for whey protein. Indeed, 2 studies have reported a positive association between birth weight and maternal consumption of milk and yogurt, but not for cheese. Whey protein, which is particularly abundant in breast milk and more digestible than casein, could be a contributing factor to birth weight.

Lipoproteins and Cardiometabolic Health Researcher, Dr Arsenault has authored or co-authored more than 80 peer-reviewed scientific manuscripts in major medical, scientific and cardiology journals: the Journal of the American Medial Association, Nature Communications, Circulation, the Journal of the American College of Cardiology and the European Heart Journal.

How would you describe the role of a healthy diet, specifically yogurt, in cardiovascular disease prevention?

Cardiovascular prevention begins in the kitchen. Recently, very large epidemiological studies have shown that individuals who follow a healthy dietary pattern may have a lower blood pressure and decreased cardiovascular risk. Those dietary pattern are characterized by a high consumption of fruits and vegetables, legumes, nuts, whole grains, olive oil, fish and yogurt . Yogurt fits perfectly in that healthy dietary pattern that provides cardiovascular benefits.

What’s yogurt role in preventing the risk of high blood pressure?

There is some interesting evidence suggesting that individuals who consume yogurt on a regular basis may be at lower risk of developing hypertension than others. However additional studies, especially randomized clinical trials are needed to determine whether the association between yogurt consumption and blood pressure is causal and more importantly whether yogurt consumption should be part of blood pressure prevention and management.

What’s your opinion about the fullfat dairy story which has been quite popular lately?

The fat content of the diet poorly reflects whether a diet is healthy or not. Many individuals following a high-fat diet rich in fish, nuts, avocados, olive oil and dairy products can have a healthy body weight. They can also have a lower risk of developing cardiometabolic diseases. Interestingly, recent studies have shown that fats from dairy products can be inversely associated with the incidence of type 2 diabetes. From a public health perspective, we should be more concerned about the spectacular rise in ultra-processed food consumption around the world than our consumption of dairy fat. At the end of the day, it all comes down to dietary quality.

About Benoit Arsenault

Dr Benoit Arsenault is an Assistant Professor at the Department of Medicine at Université Laval. He is also a research scientist at the Québec Heart and Lung Institute in Canada. The research of Dr Arsenault’s team focuses on the impact of various interventions (lifestyle modification therapy, dietary interventions, physical activity and pharmacotherapy) on cardiometabolic risk markers such as body composition, insulin sensitivity as well as high-density lipoprotein (HDL) function, lipoprotein(a) and PCSK9 in humans. The laboratory of Dr Arsenault also uses state-of-the-art imaging technologies to study the determinants (dietary patterns, physical activity and genomics) and the consequences of intra-abdominal and hepatic fat on insulin resistance, atherosclerosis and aortic valve diseases.

The study of the genetic determinants of aortic valve diseases, HDL functionality and other biomarkers of lipoprotein metabolism, as well as lipid-lowering therapy pharmacogenomics is also an important research theme of Dr Arsenault’s lab. Dr Arsenault is a member of the Genomic Investigation of Statin Therapy consortium.

Dr Arsenault has authored or co-authored more than 80 peer-reviewed scientific manuscripts in major medical, scientific and cardiology journals. He is also the senior editor of the scientific journal Future Science Open Access and a member of the Scientific Advisory Board of the Lipoprotein(a) Foundation. He has peer-reviewed more than 200 manuscripts for various scientific journals.

Dr Arsenault holds a junior scholar award from the Fonds de recherche du Québec: Santé (FRQS). He has received several distinctions such as the Young Investigator Clinical Science Award of the European Society of Cardiology in 2011.

El consumo de yogur se asocia a un menor aumento de peso a largo plazo

Table of contents

Los beneficios potenciales del consumo de yogur para reducir el aumento de peso con el tiempo han sido confirmados en varios estudios de reciente publicación discutidos hoy en el III Congreso Mundial de Nutrición y Salud Pública.1,2 Los científicos han concluido que el consumo habitual de yogur está asociado con una menor ganancia de peso y un menor riesgo de tener sobrepeso u obesidad. En su presentación ante expertos de salud pública presentes en el III Congreso Mundial de Nutrición y Salud Pública celebrado en España, el profesor Frans J. Kok de la División de Nutrición Humana de la Universidad de Wageningen (Holanda) destacó el rol potencialmente único del consumo diario de yogur en el control del peso.  Sin embargo, también ha apuntado a la necesidad de ensayos controlados aleatorios y de estudios que ayuden a entender el mecanismo biológico que lo produce.

“El aumento de las cifras de sobrepeso y obesidad constituyen una gran preocupación en todo el mundo y uno de los principales desafíos para la salud pública en el siglo XXI”, afirma el profesor Kok.  “La mayoría de los adultos entre los 18 y 49 años aumentan alrededor de 1 kilo de peso cada año, convirtiendo la prevención del aumento de peso en un verdadero problema de salud pública.”

Dos estudios demuestran los beneficios potenciales

Dos estudios publicados recientemente han demostrado los beneficios potenciales del yogur en el control de peso y la reducción del riesgo de tener sobrepeso u obesidad.  En el primer estudio1 que evalúa la asociación longitudinal entre el consumo de productos lácteos y cambios en el peso corporal, basado en los datos obtenidos durante 17 años (1991-2008) de los descendientes de los participantes originales en el estudio ” Framingham Heart Study Offspring Cohort”, las individuos que consumían tres o más raciones de yogur a la semana ganaron un 50% menos de peso durante ese período (P=0.03) y tenían alrederor de un 20% menos de perímetro abdominal al año (P=0.008) que las individuos que consumían menos de una ración de yogur a la semana.

El segundo estudio prospectivo hizo un seguimiento a más de 8.500 hombres y mujeres cada 2 años entre 1999 y 2012 para evaluar la asociación entre el consumo de yogur, el aumento de peso anual y el desarrollo de obesidad.2  Ninguno de los participantes tenía sobrepeso al inicio del estudio; sin embargo, al cabo de un promedio de 6,6 años, 1.860 individuos tenían sobrepeso o estaban obesos.  El estudio demostró que los individuos que consumían más yogur (al menos 7 unidades a la semana) tenían menor probabilidad de tener sobrepeso o estar obesos – con al menos un 12% menos de riesgo.  “Estos estudios se suman al creciente número de evidencias científicas que sugieren que el yogur puede tener un efecto beneficioso sobre el aumento de peso, pero necesitamos estudios controlados aleatorios para confirmarlo”, comentó el profesor Kok.  “También debemos investigar el potencial rol del yogur en la pérdida de peso de individuos con sobrepeso, y estudiar específicamente los efectos del yogur en la reducción de la grasa corporal.”

¿Cómo puede el yogur ejercer sus efectos beneficiosos sobre el peso?

El yogur es rico en muchos nutrientes como proteínas, las vitaminas B-2, B-6 o B-12, calcio, potasio, zinc o magnesio y, además, la acidez del yogur aumenta la biodisponibilidad de nutrientes específicos como el calcio.  Una revisión reciente de Jacques y Wang3 sugiere un número de mecanismos potenciales subyacentes para facilitar la pérdida de peso y grasa corporal, entre ellos, la capacidad del calcio y otros nutrientes (p.e. seroproteínas y caseína, péptidos bioactivos, aminoácidos o ácidos grasos) que se encuentran en abundancia en el yogur , la posibilidad de que el yogur sea más saciante que otros alimentos y, el potencial de las bacterias probióticas en el yogur para interactuar favorablemente con la flora intestinal.

“El yogur  es un alimento de alta densidad nutricional y contiene probióticos con beneficios comprobados para la salud,” dice el profesor Kok. “Aunque se requiere más evidencia sobre el beneficio del consumo de yogur en el control de peso, no hay duda de que el yogur encaja bien en una alimentación saludable, ya que es un alimento de alta densidad nutricional y bajo en calorías, lo que ayuda a la población a cubrir sus objetivos nutricionales.”
