Just learnt from one of the students that there is a research group working on creating iron-rich bananas - who knew?!

Nutrition Research Scientist
I am a nutrition researcher, working for the ‘Healthy Cheeses’ group in UCD. One of the things I look at it the intake of various types of cheese in Ireland, and how they impact our nutrition.
Cheese is a really good source of lots of nutrients, like calcium, magnesium, phosphorus, and B-vitamins, which are needed for lots of things in our bodies, like bone health as well as muscle and brain function. However, cheese is also a source of salt, which is already too high in our diets, and a source of saturated fat, which many people believe to have a negative impact on heart health.
Recent evidence suggests that the link between saturated fat and heart disease also depends on the food, and that cheese may in fact have a positive impact on heart health! The theory is that there is something special about the matrix of cheese – the saturated fat in cheese is held together in a structure, with calcium and proteins that may affect how the fat is processed by the body. I am currently running a study to look at this ‘matrix’ theory in more detail. I am also interested in sensory evaluation – the science of how we see, smell, touch as taste things – and how different people can have different perceptions due to their genetics.
My Typical Day
I meet participants, take some blood, and send them away with cheese to eat every day for the next 6 weeks.
What I'd do with the prize money
I would use it to develop an app that could help people count their own tastebuds on their phone! (See the last picture)
How would you describe yourself in 3 words?
Fun, energetic, creative.
What did you want to be after you left school?
An artist or a scientist.
Were you ever in trouble at school?
Hmm, yes, all the time (for talking!)
Who is your favourite singer or band?
What's your favourite food?
Well, I have to say cheese don’t I?!?
What is the most fun thing you've done?
Two years ago I went snorkelling on the great barrier reef with my twin sister. We saw lots of clown fish (like Nemo).
If you had 3 wishes for yourself what would they be? - be honest!
A massive grant to do research in taste and food choice would be my number one wish.
Tell us a joke.
A neutron walks into a bar and orders a drink. The barman says “For you – no charge” (Heehee)
Giving some visiting students a demo in the sensory booths – that’s where you taste and smell foods to evaluate them.
Someone really didn’t think things through when they weighed out their sugar…
A close-up of our sensory booths.
This is a picture of a tongue with blue food colouring on it. The blue food colouring helps the fungiform papillae (little bumps that house the tastebuds) stand out. And then you can count them. Some people have lots of these bumps while others have just a few. The jury is still out on whether that can affect how you perceive tastes and textures.

This is so cool. Its a container of PTC, and its from the 1980s or earlier, had to take a pic, very impressed. Its well past the expiry for using in experiments, but its cool to see that the research looking at differences in taste has been going on for so long! It was in the 1930s that a chemist first discovered that some people find this really bitter bitter, and others don’t.
