Happiness Apparently Makes You Eat Candy

From A Basket Case.

The Times of India reports that happy people tend to eat candy, while "hopeful" people eat fruit and vegetables. This comes from a series of studies by Karen Page Winterich of Pennsylvania State University and Kelly L. Haws of Texas A&M University. They got their results by having participants either thinking about the past, present, or future, then seeing whether they picked candy or fruit.

In the first study, hopeful participants ate less M&Ms than those thinking of present happiness. In the second, participants thinking of the past ate even more unhealthy snacks. In the third study, participants thought of positive emotions in the past and the future. The "future" people chose healthier food.

The study authors conclude, "So the next time you're feeling well, don't focus too much on all the good things in the past. Instead, keep that positive glow and focus on your future, especially all the good things you imagine to come. Your waistline will thank you!"

Overall, this sounds like a rather unconventional series of studies with a lot going on. The article doesn't go into much detail, but it sounds like different snacks were used in each study (M&Ms in one, unspecified candy bars in another, etc.), which could make the conclusions suspicious because of all the variables. I also hope the authors kept strict definitions of "hope," "pride," and "happiness," as these are somewhat airy concepts that participants could have defined however they wanted.

Study Shows Correlation Between Diet and Mental Disorders in Women

Mmm, depression! From Science Daily.

Today the Sydney Morning Herald reports on a new Australian study that shows eating certain foods increase the likelihood of developing depression and anxiety disorders. Lead by Deakin University research fellow Dr. Felice Jacka, the study examined around 1,000 Australian women from all stratas of society. Participants who followed the national dietary guidelines were less likely to have depression.

This correlation happened regardless of the women's socioeconomic status, education, frequency of exercise, whether they smoked or not, and even physical problems like obesity. Dr. Jacka also says, "And conversely, women who mostly ate junk and processed foods were more likely to have depression and exhibit increased psychological symptoms." The study ultimately aims to help prevent depression before it starts.

So this pretty much confirms what a lot of you probably expected anyway. Unfortunately, the news story doesn't go into much detail about how this study was carried out (by listing control groups and the like), so not much else can be inferred from it.

Casual Friday: Foods That Make You Happier

Today I thought it would be nice to highlight diet tips that can improve your mood, using this article by Elsa Jones from Herald.ie and this article by Mary Bourgeois from Top Wire XS as guidance. As most of you probably know, food can have a big effect on levels of your serotonin, also known as the "happiness hormone" (even though it's a neurotransmitter, not a hormone). But what kind of diet is best? Let's find out!

1. Eat folate-rich foods. A study by the University of York and the Hull York Medical School showed that low folate levels can lead to depression, so eat foods like peas, bananas, oranges, broccoli, and others like them.
2. Eat protein with every meal. Protein-rich food keeps blood sugar balanced and contains tryptophan, which is necessary for serotonin production. Some good foods in this category are turkey, cottage cheese, and bananas.
3. Eat B vitamins, especially B6. B vitamins help with serotonin production, but B6 also helps in the metabolism of red blood cells. B-vitamin foods include oats, leafy green vegetables, and eggs.
4. Eat omega-3 foods, like fish. A study by the Journal of Clinical Psychiatry showed that eating fish capsules three times a day improved bipolar and depression patients' moods after eight weeks. This makes sense because omega-3 helps create dopamine (another neurotransmitter related to happiness) and slows the breakdown of serotonin.
5. Eat vitamin D. Most of us don't get enough vitamin D from sunlight, especially in the winter, which can cause problems because this vitamin is a mood booster. Some good vitamin-D foods are oily fish, leafy green vegetables, and eggs.

So there you have it. Give some of these tips a try. You'll probably be glad you did!
