Eating slowly may cut meal size

People may consume fewer calories over the course of a meal when they eat slowly, a new study suggests. But it's not clear if that strategy works as well for people who are overweight or obese as it does for their slimmer peers.
Past studies have come to mixed conclusions on whether how fast people eat affects how much they end up eating, Meena Shah said. She led the new research at Texas Christian University in Fort Worth.
"In addition most of the previous studies have not compared the effect of eating speed on energy intake in normal weight or overweight and obese subjects," Shah told Reuters Health in an email.
Her team's study included 35 normal weight people and 35 who were overweight or obese.
All of the participants were asked to eat the same vegetarian pasta meal on two different occasions. The first time around, people were asked to eat either quickly or slowly, based on a random assignment. A few days later, they were given the opposite instructions.
On fast eating days, the researchers asked participants to eat as quickly as possible without feeling uncomfortable - as though they had time constraints. They told them to take large bites, chew quickly, not put utensils down and not pause between bites.
On the slow eating days, they told people to eat as if they had no time constraints. They instructed them to take small bites, chew thoroughly and put their fork or spoon down and pause between bites.
The researchers secretly measured how much food participants ate by weighing their plates after meals.
Normal weight participants consumed 88 fewer calories during the meal when they ate slowly, on average - 805 calories compared to 893 calories during the faster meal. That was a clear change.
Overweight and obese people consumed 58 fewer calories during the slow meal - 667 calories versus 725 calories. But that difference could have been due to chance, according to findings published in the Journal of the Academy of Nutrition and Dietetics.
Shah believes the overweight and obese participants may have eaten less because they felt self-conscious during the study.
Participants in both groups drank more water when they ate slowly and felt less hungry at the end of the meal.
"This study provides new data that supports the hypothesis that how you eat may have an effect on appetite and influence body weight", James Hollis told Reuters Health in an email.
Hollis, from Iowa State University in Ames, was not part of the new research.
"This is an interesting study and any method that reduces food intake by 8-10 percent at a single meal would be useful," he said. But more studies are needed to show whether eating slowly could help people manage their weight, Hollis said. His own recent report published in the same journal found people tended to eat less when they were instructed to chew more before swallowing.
"It has not been adequately determined how slow is slow enough or what is the minimum reduction in eating speed required to have an effect on food intake," Hollis said.
He said it's also not clear if all of the techniques - chewing slowly and more times and taking more pauses during meals - have the same effect on how much people eat.
"I would recommend slowing the speed of eating because it may reduce the amount of food consumed as well as lead to a greater degree of fullness or less hunger later on. It is not necessary to time the meal, though," Shah said.
"Eating in my opinion should be an enjoyable experience without having to check the time," she said.

Both genetics and environment may influence children’s food preferences

Researchers from University College London, UK, performed a large-scale twin study to investigate the relative contribution of genetic and shared environment factors to children’s preferences for certain food groups. The study revealed a substantial genetic influence on preferences for fruits, vegetables and proteins. Further analyses showed that a shared environment has more impact on preferences for dairy, starch and snacks. Based on these findings, the researchers concluded that both genetics and environment may influence children’s food preferences. The importance of providing children with a healthy diet is beyond any doubt, but, according to the researchers, there are different views between parents and health professionals on what influences children’s food preferences. On the one hand, health professionals claim that dietary habits are mainly derived from the ‘home food environment’ and are learned (nurture). Being offered more nutritious and less energy-dense foods would, therefore, guide children’s dietary choices. But parents believe that despite their efforts to provide a healthy diet, some children simply dislike certain sorts of foods, indicating genetic influences on taste (nature).
In order to assess the impact of genetics, twin studies are usually performed. They are a good model to distinguish the contribution of genetic and environment factors. Twins can be monozygotic or dizygotic. Monozygotic or ‘identical’ twins developed from one fertilised egg cell (zygote) that splits and forms two embryos. They share 100% of their genes. Dizygotic or ‘fraternal’ twins develop from two eggs, each fertilised by a separate sperm cell, and share 50% of their genes. In order to achieve the best results on the effect of genetic and environmental factors on - in this case - food preferences, twin studies should have large sample sizes and test a wide variety of foods.
The participants in this study came from families that took part in a population-based observational study (cohort) of twins born in the United Kingdom in 2007. For a total of 2,686 twins, both identical and fraternal (34% and 65% respectively, with about 1% of which this was unknown), with an average age of 3.5 years, food preferences of the children were recorded by their parents.
Given the age of the children and the sample size of the study, neither self-reporting by the children nor observation by a professional were possible, the researchers relied on the parents for the data collection. The preferences were analysed for 84 foods, divided-up by the researchers into six categories: vegetables, fruits, proteins, dairy, starches, and snacks.
Firstly, children’s ‘liking’ towards the foods was assessed. The results showed that the least liked group was vegetables, where only four (sweetcorn, peas, tinned tomatoes and cooked carrots) out of 19 types were liked by children. The most liked group was the one defined as snacks and all foods in this group (including sweets, chips, cakes and ice cream) were liked. Correlations between preferences for the food groups were then calculated. The strongest correlation (or relation) was seen between fruits and vegetables, meaning that children who liked fruits also liked vegetables. The weakest correlation was observed between vegetables and snacks. The researchers also measured whether there was an effect if the child was either an identical or fraternal twin, but they did not find any effect on the above mentioned correlations.
The researchers finally assessed the extent to which genetics and the environment play a role in the preference for certain food groups. This calculation is based on a comparison of correlations between monozygotic and dizygotic groups. It was shown that genetics have a stronger influence on preference for fruits, vegetables and proteins, and a lower influence on preference for snacks, starches and dairy. The shared environment, when children live with their parents in a family, had a strong effect on the preferences for snacks, starches and dairy, and was moderate for fruit, vegetables and proteins. The effect of the non-shared environment, experienced outside of the family, was small for all food groups. This can be explained by the fact that the children were still young, brought up in the same home, and not exposed much to different environments (schools, playgrounds, etc).
This large-scale study demonstrates that both genes and the environment are important determinants of food preferences in children, and that their relative importance depends on the type of food. The fact that liking of fruits, vegetables and proteins is more strongly determined by genetics does not mean that our genes are the sole influencer, and that the innate preference cannot be changed. The family environment also has a strong role to play. Therefore, parents and care-givers should keep encouraging children to taste new foods, and persistently offer a variety of flavours and textures – also those that are initially disliked. This could prevent a too restricted food choice later in life.

Several forms of vitamin E protect against memory disorders

Elderly people with high serum vitamin E levels are less likely to suffer from memory disorders than their peers with lower levels, according to a study published recently in Experimental Gerontology. According to the researchers, various forms of vitamin E seem to play a role in memory processes. The study was carried out in cooperation between the University of Eastern Finland, the Finnish National Institute for Health and Welfare, Karolinska Institutet, and the University of Perugia.
Studies investigating the link between vitamin E and memory disorders have usually focused on a single form of vitamin E, namely α-tocopherol, which is also used in vitamin E supplements. However, vitamin E exists in eight different natural forms, tocopherols and tocotrienols, all of which have antioxidant properties.
This recently published study comprises a sample of 140 over 65-year-old Finnish persons with no memory impairment at the onset of the study. During the eight-year follow-up, it was discovered that higher total serum levels of vitamin E, and higher levels of γ-tocopherol, β-tocotrienol and total tocotrienols in particular, seemed to protect against memory disorders. According to the researchers, the results show that the entire vitamin E family plays a role in memory processes. Accordingly, measuring the levels of vitamin E from serum is the most reliable way to determine whether they are sufficiently high.
The study comprised part of the more extensive Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study, which focuses on the association between the risk factors of cardiovascular diseases and memory disorders.

Dietary fibre protects against asthma

The Western diet probably has more to do with the asthma epidemic than has been assumed so far because developing asthma is related to the amount of fruit and vegetables consumed. Gut bacteria ferment the dietary fibres contained in them and fatty acids enter the blood as a result, influencing the immune response in the lungs. This has been shown by a research project funded by the Swiss National Science Foundation (SNSF).
In the West, an increasing number of people have developed allergic asthma in the past fifty years. But dietary habits have also changed during the same period: fruit and vegetables are playing an ever smaller role in people's diets. Now new results suggest that these two developments are not merely simultaneous, they are also causally linked. A team of researchers led by Benjamin Marsland from Lausanne University Hospital (CHUV) has shown in experiments with mice (1) that the lack of fermentable fibres in people's diet paves the way for allergic inflammatory reactions in the lungs.

Influence extends to the lungs
Researchers have already known for some time that the microbial diversity in the gut when digesting and fermenting fibres plays a significant role in preventing intestinal cancer. "We are now showing for the first time that the influence of gut bacteria extends much further, namely up to the lungs," says Marsland. His team either put mice on a standard diet with four percent fermentable fibres or gave them low-fibre food with merely 0.3 percent fermentable fibres. This low-fibre food is largely comparable to the Western diet, which contains no more than 0.6 percent fibres on average.
When the researchers exposed the mice to an extract of house dust mites, the mice with the low-fibre food developed a stronger allergic reaction with much more mucus in the lungs than the mice with the standard diet. Conversely, a comparison between mice on a standard diet and mice who received food enriched with fermentable fibres likewise showed that these dietary fibres have a protective influence.
This protection is the result of a multi-level reaction chain, as Marsland's team has now shown. First the fibres reach the intestine, where they are fermented by bacteria and transformed into short-chain fatty acids. These acids then enter the bloodstream and influence the development of immune cells in the bone marrow. Attracted by the extract of house dust mites, these immune cells wander into the lungs, where they eventually trigger a weaker allergic response.

Another reason why fruit and vegetables are good for you
Marsland thinks that the results obtained by his group are clinically relevant not only because the share of plant fibres in Western diets is comparable to the low-fibre food of the mice, but also because the examined aspects of the immune system are virtually indistinguishable in mice and humans. Many questions still remain unanswered. "We plan to conduct clinical studies to find out how a diet enriched with fermentable fibres affects allergies and inflammations." It is already sufficiently clear, however, that here is another reason why one should eat more fruit and vegetables.
