My blogging buddy James Bishop over at Finding Optimism wrote a superb post on food allergies, and how they contribute to mood. My sister is finding the same with her special needs boy, and continues to hound me about possible intolerances in my diet, as well, like food coloring and preservatives. Here are the first three paragraphs of James’s article. To read the whole thing, click here.

My son is allergic to green peas and his reactions are life threatening. He is intolerant to a lot of other foods as well, and as we’ve found out, so am I.
We changed our family diet some years ago now, for the sake of us all. I used to cheat, but I also kept track of my diet, and after a while my wife noticed that when I ate certain foods I would become very depressed 2 days later. (Almost to the hour.) Unfortunately chocolate was the worst! She mentioned this bizarre discovery to our allergy specialist who said “Yes, food does cause mood swings!”
Food allergies and intolerances are very different things. Food allergies trigger the immune system, and the sufferer’s body reacts, for example with swelling or hives. Food intolerance is about thresholds. You can eat the foods that you’re intolerant to, but you’ll have a reaction if you go over your threshold. Food intolerance is very common; much more than people seem to realize.
The reactions can be amazing. In me the intolerance causes depression. My wife feels bloated and lethargic. The kids get aggressive and irritable. Other people report anxiety, panic attacks, suicidal thoughts, obsessive compulsive behaviour and even social phobias. Migraines and stomach aches are also common.

When does reciting scripture become a symptom of neurosis? Or praying the rosary an unhealthy compulsion? Not until I had the Book of Psalms practically memorized as a young girl did I learn that words and acts of faith can morph into desperate measures to control a mood disorder, that faithfulness and piety can disguise acute […]

One of my mom’s best pieces of advice: “Hang with the winners.” This holds true in support groups (stick with the people who have the most sobriety), in college (find the peeps with good study habits), and in your workplace (stay away from the drama queen at the water cooler). Why? Because we actually become […]

For people prone to depression and anxiety – i.e. human beings – the holidays invite countless possibility to get sucked into negative and catastrophic thinking. You take the basic stressed-out individual and you increase her to-do list by a third, stuff her full of refined sugar and processed foods, force her into social gatherings at […]
