Remember when your parents used to say, “Eat your greens, they are good for you”? Well, they were really onto something. Several studies have shown that higher intakes of cruciferous vegetables like broccoli, one of the most widely consumed vegetables in the United States, are associated with reduced risks of diseases such as diabetes and cancer, thanks to their organosulfur compounds, such as glucosinolates and isothiocyanates that exhibit a broad spectrum of bioactivities including antioxidant activity. However, few studies have focused on the endogenous content of polysulfide in broccoli sprouts.
A research team led by Assistant Professor Shingo Kasamatsu and Professor Hideshi Ihara of the Graduate School of Science at Osaka Metropolitan University, investigated the amount of polysulfides in broccoli sprouts during the process of their germination and growth. Building upon their previous work, where the research team demonstrated the abundance of polysulfide molecules in cruciferous vegetables.
The team found that total polysulfide content in broccoli sprouts significantly increased during germination and growth, with an approximately 20-fold increase in polysulfides on the fifth day of germination. Furthermore, they discovered a number of unknown polysulfides with indeterminate molecular structures. These findings suggest that the abundance of polysulfides in broccoli sprouts may contribute to their well-known health-promoting properties.
Dr. Kasamatsu stated, “The discovery of the significant increase in polysulfide content during the sprouting process from broccoli seeds was completely by chance and very surprising. This finding suggests that polysulfides may play an important role in the process of plant germination and growth. Further investigation of the pharmacological function of these unknown polysulfides could lead to the development of new preventive and therapeutic approaches and medicines for neurodegenerative diseases, stroke, cancer, inflammation, and other oxidative stress-related diseases.”

Children as young as four eat more when bored
Peer-Reviewed Publication- A new study carried out at Aston University found that children as young as four eat 79% more calories on average when they are bored
- Children with more emotional temperaments whose parents used food to soothe them ate five times more calories when bored
- It is the first study to link children’s emotions and parental feeding habits in this way.
A new study carried out at Aston University has shown that children as young as four years old eat 79% more calories when they are bored, compared to when they are in a neutral mood.
Despite boredom being a common emotion experienced by many children, no research to date has looked experimentally at how much more children eat when bored. On average, the study shows that children who were feeling bored ate 95 kcal when they were already full, compared to children in a neutral mood condition who ate just 59 kcal. The pioneering research was led by Dr Rebecca Stone as part of her PhD, supervised by Professor Claire Farrow and Professor Jackie Blissett from Aston University, and Professor Emma Haycraft from Loughborough University.
Children’s eating behaviour is shaped by their genetics, temperament, and a range of other factors, including the feeding practices they experience. In previous research, the authors have explored the behaviours that make children more likely to eat when they experience negative emotions. Often when children experience negative emotions such as boredom or sadness, adults will use food to soothe them. However, this behaviour, which is known as emotional feeding, appears to enhance the likelihood of children eating more when they are upset, potentially teaching children to seek food when their mood is low.
As part of the study the researchers asked parents about the feeding practices that they used with their child and about their child’s temperament. Children and parents were given a standard meal that they ate until they were full. Children then took part in a series of everyday conditions where their mood was assessed and one of these conditions was boring for the children. The researchers found that if parents reported using food to soothe their child’s emotions often and their child was highly emotional children ate five times more kilocalories when feeling bored (104 kcal) compared to in a neutral mood (21 kcal).
Dr Stone said:
“If children are eating this many more calories during one instance of boredom induced in a laboratory (a four-minute period), given that boredom is a commonly experienced emotion in children, the potential for excess calorie intake in response to being bored across one day, one week, or one year, is potentially very significant in a food abundant environment.”
Previous studies on what can influence eating behaviour in children have tended to be based on questionnaires, with all negative moods, including sadness, anger and anxiety, grouped together. Boredom is easily identifiable, and generally easily rectified, so helping parents to deal with children’s boredom without using food would be a potentially helpful way of reducing less healthy snacking.
Dr Stone stresses that the experience of boredom is important in the development of children’s sense of self and creativity, so does not recommend that children could or should avoid being bored. Instead, she suggests that children need to learn to experience boredom without turning to food, and that parents could try to divert their child’s attention away from food when feeling bored, or restructure the home food environment to make it less likely that children turn to food when they are bored.
Professor Farrow said:
“It is commonly assumed that children tend to turn to food when bored and that some children are more likely to do this than others. This is the first study to experimentally test this in the laboratory. Whilst there do appear to be individual differences between children in terms of their eating when bored, it is helpful to know that the feeding practices that adults use around food might shape the likelihood of this happening. Although it is tempting to use food as a tool to comfort children, research suggests that emotional feeding might lead to greater emotional eating in the future. It is important that parents and caregivers are aware that this short-term fix could create future challenges.”
The research team are interested in exploring other negative mood states in children and in developing advice and support for families to find effective ways to manage challenges around child eating behaviour.
