If there are two things most, if not all, mothers tell their kids to eat, it’s their greens and breakfast. They encouraged these for good reasons too, as both are healthy for growing kids and adolescents. But now, a new study shows that eating spinach and eggs, which are both high in the amino acid tyrosine, can boost a person’s reflexes. The amino acid is a precursor in the production of norepinephrine and dopamine, both of which increase energy, alertness, and improve mood when together. With that in mind, researchers from the University of Leiden and the University of Amsterdam in the Netherlands wanted to see how well it improved reflexes.

The study
They created a situation in which test candidates had to interrupt a repetitive activity at a given instant. The researchers tested this using a stopping task: the participants were told to look carefully at a computer screen. Whenever a green arrow appeared, they had to press a button as quickly as possible. At the same time they had to make sure the button they chose matched the direction of the arrow. If a red arrow appeared on the screen, the candidates had to keep their hands off the keyboard altogether.
The participants had two sessions in the test lab. On one occasion they were given orange to drink that contained tyrosine, and on the other occasion the orange juice contained a placebo. The tests showed that the candidates performed better on the stopping task if they had drunk the juice with tyrosine.

Benefits
The positive effect of tyrosine on our reaction speed can have benefits for road safety. For example, if a queue suddenly forms, fast reflexes can prevent an accident. But there are many more examples. Colzato: 'Tyrosine food supplements and tyrosine-rich food are a healthy and inexpensive way of improving our intellectual capabilities. This makes them preferable to Ritalin and Modafinil, products that students often reach for to improve their academic performance. Tyrosine is safe and doesn't need a doctor's prescription.'

What is tyrosine?
Tyrosine isn’t only found in spinach and eggs either, although it’s possible to make a great breakfast with both, and they’re both good for the body. It can also be found in soy, cottage cheese, chicken, turkey, peanuts, avocados, and bananas, among other foods.
Anyone who doesn't eat enough of these foodstuffs produces too little dopamine, which can lead to depression and apathy.

Start your day with a tyrosine-rich breakfast
