I can already tell that this latest study and other reports on food and mood will be an import factor in my quest for living a healthy lifestyle and reducing my risk of disease and cognitive decline, I’m hoping you’ll be able to link up with this information and join me on my journey.
In my last post, I wrote about the Sanchez-Villegas Spanish study relating to how food affects mood. Even though the study was not designed to look at particular fats, there was enough evidence to support that monounsaturated fats, like those in olive oil, help bridge the gap or synapse between nerve cells so that they can communicate with each other.
We already know that serotonin regulates mood, anger, aggression, appetite and even some cognitive functions. When serotonin is converted to the hormone melatonin, it helps you sleep. For instance, Prozac and Zoloft are selective serotonin reuptake inhibitors which block the reabsorption of serotonin leaving more work in the synapses.
Since the membranes of our neurons are made of fat, the quality of fat that we eat has an influence on the quality of our neuron membranes. Vitamin B6 and folate, found in vegetables, fruits and nuts and legumes, are all part of the Mediterranean diet and all important to healthy serotonin.
The study also reports that the effects of B vitamins and folic acid may reduce depression because it impacts the metabolism of two amino acids, homocysteine and methionine. In other words, this kind of diet can improve blood vessel function, fight inflammation and repair oxygen related cell damage all of which reduces the changes of developing depression.
Practical tip: For the most beneficial effect of either carbohydrate or protein, eat them separately. For instance, the energy boosting effect of protein will be offset if you start out a lunch of fish with a roll which is mostly carbohydrate. Make the protein the first food that you eat, and then go lightly on the carbohydrate if you are looking for mental alertness.
If you have questions, ask away. I will be posting about this topic throughout the year.
To your success at healthy aging.
