Our Moods, Our Foods

Eating a meal, any meal, reliably makes an animal, any animal, calmer and more lethargic. This means humans, too. Hunger makes animals alert and irritable, which explains why couples always fight about where to eat dinner. This emotional response encourages the animals to find food.

But all this is only in the broadest, most primal “eating = good, not eating = bad” way. The details of the relationship between foods and moods end up being a little contradictory and a lot complicated.

What we tend to think of as “emotional eating” is a specific kind of eating and a specific kind of emotion—eating sugary, fatty, carb-y, unhealthy foods as a coping mechanism for feeling upset.  In reality, “emotional eating” is a much broader term.

“We eat for a variety of different emotions and we eat in a variety of different circumstances which are in turn connected with emotions,” Meryl Gardner, a marketing professor at the University of Delaware, says.

Gardner was the lead author on a new study published in the Journal of Consumer Psychology, which looked at food choice and mood, adding to a fairly extensive body of research that already exists on the interplay between moods and foods.

There seems to be a consistent connection between negative emotions and unhealthy foods. What's less clear is what foods we're drawn to in a positive mood.

There seems to be a clear, fairly consistent connection between negative emotions and unhealthy foods, though there are individual variations for what kind of snack people want. In a bad mood, people’s hands tend to float to the cookie jar, the candy bag, the snack drawer. What’s less clear is what foods we’re drawn to in a positive mood.

Some studies say we still want treats. A 1992 study and a 2002 study (one on women, one on men) found that joy led to increased consumption of indulgent foods. A 2013 study in Appetite titled “Happy Eating: The underestimated role of overeating in a positive mood” points out the potential for increased consumption (in this case of chips and chocolate) when we’re feeling good.

Other research says just the opposite—that we’re more likely to eschew the sugar/carb rush when happy. In 2010, researchers found that people in a positive mood were more likely to choose grapes over chocolate than those in a neutral mood. Another study offers a qualification, finding that people would choose healthy foods if they felt like their good mood was going to stick around; if not, they might eat more indulgent foods, to keep the good vibes going.

Gardner’s study also found a connection between negative moods and unhealthy foods, and positive moods and healthy foods, but she and her team introduced the element of time into the equation as well. They had participants think about either the present or the future (by describing their current residence, or a possible future residence). They found that regardless of mood, long-term, future-focused thinking led to healthier choices.

“When you’re in a good mood, you take a longer-term perspective,” Gardner says. “You see the forest, not the trees... When you’re focused on the near term, when you’re looking at what’s in front of your nose, you respond with what’s going to give you quick pleasure. And that’s triggered very much by bad moods. But we can fight that.”

Dr. Leigh Gibson, a psychology professor at the University of Roehampton in London, disagrees, though he says he finds those results interesting. “I’m not sure that’s the way people normally go about their daily eating,” he says. “For habitual behaviors like eating, there tends to be an intention-behavior gap. We have all these wonderful intentions, but when it comes down to it, we’re exposed to energy-dense foods when we find ourselves hungry.”

It does seem unlikely that most of us would take the time to describe our future homes to ourselves before deciding on pizza or a salad for lunch. And as previously noted, there is little consensus on what we typically crave when we’re happy.

"Healthy eating is a modern thing that we now need because we're living so long. You could almost say the default is comfort eating."

Part of the reason why it seems our moods rarely drive us toward healthy foods, Gibson says, is that for much of human history, energy-dense foods, or what we now consider comfort foods, were the ideal thing to eat.

“We didn’t evolve as homo sapiens by eating healthy, because all we had to do was reproduce and survive until our mid-20’s,” he says. “We were quite happily sucking the marrow out of bones. We were just getting energy, protein, the basic nutrients we needed, but we didn’t have to live too long. Healthy eating is a modern, cultural thing that we now need, because we’re living so long… You could almost say the default is comfort eating.”

We’re not constantly shoveling mashed potatoes into our mouths (at least not most of the time), so of course this doesn’t mean that humans don’t ever choose healthy foods, just that when we do, it might not be in response to our emotions.

Another reason for this lack of consensus is that there are a variety of moods that can fit under the “positive” umbrella—feeling excited is very different from feeling content, and those emotions could lead to similarly divergent food choices.

For example, Gardner says we tend to go for special, often unhealthy, foods on celebratory occasions, like birthdays or Thanksgiving.

“You eat the birthday cake, you may go out in the evening and eat more appetizers and drink more cocktails than you intended, and it’s all part of the specialness of the occasion,” she says. “And we’ve all learned to celebrate with food. It’s part of so many different cultures.”

Carol Landau—a clinical professor of psychiatry, human behavior, and medicine at Brown University—points out that some comfort eaters turn everything into a celebration, rewarding themselves with food not just for special occasions, but for everyday accomplishments as well.

“Food is such an important part of culture,” Landau says. “I think we’re asking people to do a lot [by asking them] to avoid comfort eating.”

Gibson says this sort of celebratory eating seems to be more prevalent for men than women. There’s also some evidence that the foods men and women turn to for comfort are different—men often get more comfort from savory foods and “general meal-type foods,” Gibson says, as opposed to snacks. Gardner says she has also found men to be more drawn to salty foods.

Sweet foods, however, seem to be a universal crowd-pleaser.

“Sweetness is such a powerful stimulus,” Gibson says. “We’re born initially liking sweetness. It probably helps [that babies] have an appetite for breast milk and so on.”

This may well be why the go-to image of comfort eating in culture is someone crying into a pint of Ben & Jerry’s, and why so many studies on mood and food choice include chocolate as one of the unhealthy options.

“If one can characterize [comfort] foods in any simple way, it would be that they’re typically energy-dense,” Gibson says. “Therefore they’re probably high fat, and they might be sweet as well. The perfect comfort food might be chocolate.”

In the chicken-or-the-egg problem of food and mood, do the moods hatch the foods, or do the foods hatch the moods?

But as we all know, the positive effects of eating sweets are short-lived. Whether it’s a crash that comes after a sugar high, or just a feeling of guilt after eating more cookies than you planned, treats are not a ticket to long-term happiness.

So in the chicken-or-the-egg problem of food and mood, do the moods hatch the foods, or do the foods hatch the moods? Studies disagree—the relationship seems to go both ways. A couple recent studies suggest that the foods come first.

In a study published in 2012, Penn State psychology professor Dr. Helen Hendy had 44 undergraduate students keep week-long diaries of how they felt and what they ate. She analyzed the results in terms of four things the Centers for Disease Control and Prevention recommend we should limit to improve physical health: calories, carbohydrates, saturated fat, and sodium. Following those recommendations, Hendy found, seemed to have benefits for improving moods as well.

She found that the link between foods and moods played out over a period of two days—what you ate on day one was linked to how you felt on day three, etc. As usual, the correlation was more consistent with negative moods: “Consumption of calories, saturated fat, and sodium was significantly associated with increased negative mood two days later,” the study reads.

“Some of my research leads me to change my habits, and this one has,” Hendy says. “I have a big meeting [in two days], so today I’m going to watch my calories, my sodium, and my saturated fat, so I can hopefully have a chance to be in a good mood.”

A similar study, published in the British Journal of Health Psychology in 2013, had 281 undergrads keep a 21-day diary, and did find a correlation between eating fruits and vegetables one day and being in a positive mood the next day. The association with eating fruit was stronger for men, but both men and women benefitted from eating veggies. Participants’ BMI did not affect the association.

The exact reasons why healthy eating might make you happy are unclear, but Gibson posits that if you intend to eat healthily, and you follow through, that could put you in a good mood. “Achieving goals is part and parcel of emotional experience,” he says.

Both eating and emotion are such regular, consistent parts of our lives that it’s inevitable they would get tangled up together. Unfortunately, though research has illuminated some interesting possibilities as to how they relate to one another, the knot is still very much intact and it’s hard to see where one ends and the other begins.

“There’s not a very neat story there,” Gibson says. Regardless, there’s a bit more to it than just feeling sad and therefore reaching for a spoon and some ice cream, or whatever your preferred unhealthy snack is. It seems entirely possible that all eating is, in fact, emotional eating.

Getting Perspective: Nutrition Counseling

Definition

Nutrition counseling is an ongoing process in which a health professional, usually a registered dietitian, works with an individual to assess his or her usual dietary intake and identify areas where change is needed. The nutrition counselor provides information, educational materials, support, and follow-up to help the individual make and maintain the needed dietary changes.

Purpose

The goal of nutrition counseling is to help a person make and maintain dietary changes. For a person with a mental disorder, dietary change may be needed to promote healthier eating, to adopt a therapeutic diet, or to avoid nutrient-drug interactions. Nutrition counseling is an integral part of treatment for persons with eating disorders or chemical dependencies. Persons taking certain drugs, such as monoamine oxidase inhibitors, used to treat depression and anxiety disorders, need to follow a tyramine-controlled diet to avoid dietary interference with their medication. Many drugs used to treat mental disorders can cause weight gain or loss, so persons taking these medications may also benefit from nutrition counseling.

The nutrition counselor and individual work together to assess current eating patterns and identify areas where change is needed. Registered dietitians have met certain education and experience standards and are well qualified to provide nutrition counseling, but nurses, physicians, and health educators also provide nutrition counseling.

Description

Assessing dietary habits

Nutrition counseling usually begins with an interview in which the counselor asks questions about a person's typical food intake. Nutrition counselors use different methods to assess typical food intake.

The 24-hour recall method is a listing of all the foods and beverages a person consumed within the previous 24-hour period. The nutrition counselor may ask a person to recall the first thing he or she ate or drank the previous morning. The counselor then records the estimated amounts of all the foods and beverages the person consumed the rest of the day. The 24-hour food recall can be used to provide an estimate of energy and nutrient intake. However, people tend to over- or underestimate intake of certain foods, and food intake on one day may not accurately represent typical food intake.

A food frequency questionnaire can sometimes provide a more accurate picture of a person's typical eating patterns. The nutrition counselor may ask the client how often he or she consumes certain food groups. For example, the counselor may ask a person how many servings of dairy products, fruits, vegetables, grains and cereals, meats, or fats he or she consumes in a typical day, week, or month.

Daily food records are also useful in assessing food intake. An individual keeps a written record of the amounts of all foods and beverages consumed over a given period of time. The nutrition counselor can then use the food records to analyze actual energy and nutrient intake. Three-day food records kept over two weekdays and one weekend day are often used.

Assessing body weight

Nutrition counselors may assess an individual's body weight by comparing his or her weight to various weight-for-height tables. A rough rule of thumb for determining a woman's ideal body weight is to allow 100 lb (45 kg) for the first 5 ft (1.5 m) of height plus 5 lb (2.3 kg) for every additional inch. A man is allowed 106 lb (48 kg) for the first 5 ft (1.5 m) of height plus 6 lb (2.7 kg) for every additional inch. However, this guide does not take into account a person's frame size.

Body mass index, or BMI, is another indicator used to assess body weight. BMI is calculated as weight in kilograms divided by height in meters squared. A BMI of 20 to 25 is considered normal weight, a BMI of less than 20 is considered underweight, and a BMI of greater than 25 is considered overweight.

Identifying changes needed

The initial dietary assessment and interview provide the basis for identifying behaviors that need to be changed. Sometimes a person already has a good idea of what dietary changes are needed, but may require help making the changes. Other times the nutrition counselor can help educate a person on the health effects of different dietary choices. The nutrition counselor and client work together to identify areas where change is needed, prioritize changes, and problem-solve as to how to make the changes.

Making dietary change is a gradual process. An individual may start with one or two easier dietary changes the first few weeks and gradually make additional or more difficult changes over several weeks or months. For example, an easy change for a person might be switching from 2% to skim milk, or taking time for a quick yogurt or granola bar in the morning instead of skipping breakfast. More difficult changes might be learning to replace high-fat meat choices with leaner ones, or including more servings of vegetables daily.

In making dietary changes, each individual's situation and background must be carefully considered. Factors that affect food decisions include an individual's ethnic background, religion, group affiliation, socioeconomic status, and world view.

Identifying barriers to change

Once the needed changes have been identified, the client and nutrition counselor think through potential problems that may arise. For example, changing eating behaviors may mean involving others, purchasing different foods, planning ahead for social events, or bringing special foods to work. Some common barriers to changing eating habits include:

  • inconvenience
  • social gatherings
  • food preferences
  • lack of knowledge or time
  • cost

Setting goals

The nutrition counselor and client set behavior-oriented goals together. Goals should focus on the behaviors needed to achieve the desired dietary change, not on an absolute value, such as achieving a certain body weight. For a person working to prevent weight gain associated with certain medications, for example, his or her goals might be to increase the amount of fruits, vegetables, and whole grains consumed each day. Such changes would help prevent weight gain while placing the emphasis on needed behaviors rather than on actual weight.

Finding support

Family members are encouraged to attend nutrition counseling sessions with the client, especially if they share responsibility for food selection and preparation. Although the individual must make food choices and take responsibility for dietary changes, having the support and understanding of family and friends makes success more likely.

Maintaining changes

The challenge for the nutrition client lies not in making the initial dietary changes, but in maintaining them over the long term. Self-monitoring, realistic expectations, and continued follow-up can help a person maintain dietary changes.

Self-monitoring involves regularly checking eating habits against desired goals and keeping track of eating behaviors. Keeping a food diary on a daily or periodic basis helps the individual be more aware of his or her eating behaviors and provides a ready tool to analyze eating habits. Sometimes a simplified checklist to assure adequate intake of different food groups may be used.

Individuals and nutrition counselors should not expect perfect dietary compliance—slips inevitably occur. The goal is to keep small slips, such as eating a few extra cookies, from becoming big slips, like total abandonment of dietary change. The counselor can help the client identify situations that may lead to relapse and plan ways to handle the situations ahead of time.

Nutrition counseling is an ongoing process that can take months or years. In follow-up nutrition counseling sessions, the individual and counselor analyze food records together and problem-solve behaviors that are especially difficult to change. Follow-up counseling also allows the opportunity to reevaluate goals and strategies for achieving those goals.
