Sugar rush or sugar crash?: A meta-analysis of carbohydrate effects on mood

Mantantzis, K., Schlaghecken, F., Sunram-Lea, S-I., & Maylor, E. (2019). Sugar rush or sugar crash? A meta-analysis of carbohydrate effects on mood. Neuroscience & Biobehavioral Reviews, 101, 45-67.

May 17, 2019 By Prof. Sandra Sünram-Lea

The effect of carbohydrate (CHO) consumption on mood is at the center of a long-standing debate, with researchers reporting both mood improvements and decrements following CHO ingestion. As global consumption of sugar-sweetened products has sharply increased in recent years, examining the validity of claims of an association between CHOs and mood is of high importance. We … [Read more...] about Sugar rush or sugar crash?: A meta-analysis of carbohydrate effects on mood

A content analysis and ethical review of mobile applications for depression: exploring the app marketplace

Bowie, D., Sunram-Lea, S.I., Sas, C. and Iles-Smith. H. (2019). A content analysis and ethical review of mobile applications for depression: Exploring the app marketplace. CHI 2019 Symposium: Computing and Mental Health. 2019.

March 5, 2019 By Prof. Sandra Sünram-Lea

Research investigating commercial mobile applications for depression have shown a range of concerns from limited research evidence, poor treatment fidelity, and issues with privacy and data security. This study advances this work through a content analysis and ethical review of app store listings of apps for depression. Whilst past content analyses and app reviews have … [Read more...] about A content analysis and ethical review of mobile applications for depression: exploring the app marketplace

The impact of diet-based glycaemic response and glucose regulation on cognition: evidence across the lifespan

Sünram-Lea, S. I., & Owen, L. (2017). The impact of diet-based glycaemic response and glucose regulation on cognition: evidence across the lifespan. Proceedings of the Nutrition Society, 76(4), 466-477.

November 15, 2017 By Prof. Sandra Sünram-Lea

The brain has a high metabolic rate and its metabolism is almost entirely restricted to oxidative utilisation of glucose. These factors emphasise the extreme dependence of neural tissue on a stable and adequate supply of glucose. Whereas initially it was thought that only glucose deprivation (i.e. under hypoglycaemic conditions) can affect brain function, it has become apparent … [Read more...] about The impact of diet-based glycaemic response and glucose regulation on cognition: evidence across the lifespan

Last in, first out: brain economy in times of limited resources

Sunram-Lea, S-I. (2017). Last in, first out: brain economy in times of limited resources. The Quarterly Journal of Experimental Psychology , 17(12), 2586-2596.

September 17, 2017 By Prof. Sandra Sünram-Lea

It has been argued that cognitive abilities that developed last ontogenetically are likely the first to become impaired when cognitive and/or physiological resources are compromised. In phylogeny as in ontogeny, the prefrontal cortex is a late developing region of the cortex. Late maturing areas of the dorso-lateral prefrontal cortex are primarily involved in higher executive … [Read more...] about Last in, first out: brain economy in times of limited resources

Nutrition and Cognition research

My research background is in biological psychology and neuroscience, and I am interested in biological factors and mechanisms which affect human cognition and behaviour across the lifespan. Much of my research has focused on the effects of glucose administration and glucose regulatory mechanisms on human cognition.

A temporary deficiency in self-control: can heightened motivation overcome this effect?

Self-control is important for everyday life and involves behavioral regulation. Self-control requires effort, and when completing two successive self-control tasks, there is typically a temporary drop in performance in the second task. High self-reported motivation and being made … Continue Reading about A temporary deficiency in self-control: can heightened motivation overcome this effect?
