More Sugar, Please.

Love sugar?  This innate desire for sweets can be traced to an ancient part of the brain — the reward circuit.  The sweet, sensory experience is recorded as a rewarding one as endorphin molecules (natural opioids) bathe the brain.  A long-lasting memory of the tasty experience is stored deep inside the brain.  There is purpose to the “feel good” experience resulting from sweetness.  You will search for, and continue to consume, the ideal fuel for your mind — the simple carbohydrates in sugar.

Nature offers fruits, vegetables, and other plant foods to satiate the need for carbohydrate — along with fiber and a wide variety of nutrients in these foods.  But nature is no competition for the added sugar in today’s super-sweet desserts, snacks, packaged foods, and beverages.  Manufacturers add some form of sugar to 74 percent of their products.

Liquid sugar, such as found in sodas, energy drinks, and sport beverages, is the leading single source of added sugar in the American diet.  The rapidly absorbed sweetened beverage is linked to sugar addiction, obesity, Type 2 diabetes (often called adult-onset diabetes), and other diseases.  Worldwide education regarding the disease risks linked to the consumption of sugary drinks has resulted in the decline of soda sales.  As summer approaches, manufacturers offer new products to quench your thirst — products called plant waters.

These beverages are made from extracts of fruits, vegetables, grains, grasses, and other plant parts, with fewer calories than sugary beverages or no calories at all.  Manufacturers of plant waters promote their products with a variety of unsubstantiated health claims.

For example:  Artichoke Water, a sugar-free, zero-calorie beverage, is claimed to be healthy because artichokes have antioxidant and anti-inflammatory properties.  Where’s the artichoke in this water?

Made with concentrated bamboo-leaf extract, Bamboo Water is stated to contain the powerful benefits of bamboo.  Is bamboo really a food source for humans?

Other beverages produced from plant sources, such as the olive, banana, cactus, barley, and maple sap are also available — all with dubious health claims and varying amounts of sugar.

Here’s a sound approach to quenching your thirst this summer.  Drink these plant waters if you like them and if you don’t mind their cost.  They lack the nutrients and fiber obtained by eating whole-plant foods, and they won’t prevent disease.  The best choice is nature’s offering:  A healthy, refreshing glass of water and some juicy, fresh fruit.  Enjoy the summer!

Diet and Alzheimer’s Disease

What weighs a mere four pounds and has a workload that demands 20 percent of all the oxygen inhaled?  Answer:  the human brain.

As technology opens the door to the unique metabolic functions of the brain, scientists are investigating the nutrients required to keep mentally sharp over the decades.

With dementia rising at an alarming rate — along with obesity, diabetes, heart disease, and other ailments — let’s eat with purpose, using sound, nutrition-related science applicable to the brain and the rest of the body.

Starting with the belief that what we eat plays a significant role in determining who gets dementia, Martha Clare Morris, Ph.D. and colleagues developed the MIND Diet as an intervention against the most common cause of neurodegeneration:  Alzheimer’s disease.

The work of Morris and her colleagues is based on research completed at Rush Medical University in Chicago, Illinois.  The term “MIND” is an acronym for Mediterranean-DASH Intervention for Neurodegenerative Delay.

The DASH diet plan is based on research sponsored by the U.S. National Institutes of Health.  The plan was developed to lower blood pressure without the use of medication.

The Mediterranean and DASH diets are models of healthy eating for the body.  The Morris team chose foods that improve brain function significantly and also added to overall body wellness.

Adherence to the MIND diet may lower the risk of Alzheimer’s disease by as much as 53%, offering more protection for the brain than any other dietary regimen.

The MIND cuisine lists 10 brain-healthy food groups (green leafy vegetables, other vegetables, nuts, berries, beans, whole grains, fish, poultry, olive oil, and wine).  The plan limits consumption of five brain-unhealthy food groups (red meats, butter/stick margarine, cheese, pastries/sweets, and fried or fast food).

The plan suggests a minimum of three servings of whole grains, a salad, and one other vegetable every day — along with a glass of wine.  For snacks, add a variety of nuts.  Berries are the only fruits recommended.

Specifically, blueberries are noted as the powerful protectors of the brain.  Strawberries are a second choice for good cognitive function.

Use Google and enter the term “MIND Diet” for daily guidelines and recipes of a cuisine designed to maximize brain function while providing healthy foods for the rest of the body as well.

Mood and Food

Posted on Posted in Brain Science, Homestudy, Nutrition, Psychology, Seminars, Webinars

What you eat can affect your risk of the most common mood disorder in the United States:  depression.

Mental health begins with lifestyle:  nutritious food; regular exercise; sufficient sleep; and coping skills.

The chemical components of food impact one’s state of mind throughout the day — that is, after every meal and snack.  A long period of time without nourishment (fasting) activates survival emotions throughout the brain.  Food, or the lack of it, thus alters both feelings and thoughts.

A significant part of the treatment program for patients with depression is a brain-healthy diet prescription designed by what may be termed a nutritional psychiatrist.  Clearly, changing one’s eating habits requires more time and energy than swallowing a pill.  However, research in mental health has appeared, showing the flaws of prescribing quick-fix medications — in the absence of healthy habits.

A recent study published in BioMed Central Medicine tested the effect of prescribing both a modified Mediterranean Diet and medication to treat patients with clinical depression.  Thirty-three percent of the patients given medication plus a modified Mediterranean Diet plan achieved remission in 12 weeks.  However, eight percent of the patients prescribed medication only reached remission in the same period of time. (Study by S. Reddy, January, 2017)  This mood-enhancing cuisine is highly concentrated in brain-protective foods:  fruits; vegetables; legumes; whole grains; raw, unsalted nuts; low-fat, unsweetened dairy foods; olive oil; and fish.

The positive effects of nutrition intervention reported in this study have encouraged psychiatrists to prioritize this diet prescription for all patients diagnosed with depression.  The modified Mediterranean food plan may help prevent the incidence of depression in persons at high risk, aid patients who reject medication, and may block the progression from mild depression to serious depression.

Regardless of one’s family history, the brain can slip into an imbalanced state that alters mood and mind-power. The wise statement, “You become what you eat,” applies to everyone.  The original Mediterranean cuisine has already scored high ratings against brain atrophy, pain, and all age-related diseases.  The Mind Diet, another modified format of the Mediterranean Diet, reduces the risk of Alzheimer’s disease.

Cook, eat, and share mood-enhancing meals.  It’s a challenge that delivers great rewards for the brain — sharper thinking and happier moments.

Finding Felicity in Food and Work

Posted on Posted in Brain Science, Continuing Education, Nutrition, Seminars, Webinars

“Life Is Good.” These three words have blossomed into a worldwide slogan.  Why?  You feel good just reading the words.

These days life elicits more worries than “happies.” Good times are short-lived and may be prone to addiction:  compulsive shopping with credit cards; eating comfort foods loaded with calories; drinking too much alcohol; or searching for drug dealers to soothe emotional or physical pain.  Sustainable happiness begins with the simple things:  the food you eat and the work you do.

Brain imaging has identified the pathway that produces good feelings.  Named the Reward Circuit, you experience an emotional response to foods consumed and work performed. Thus, the recommendation to “eat right and move more,” can improve both happiness and health.

Is eating right a happy experience?  It’s pretty obvious that foods high in fat, sugar, and salt light up the Reward Circuit, elevating feelings of joy.  Is it possible to eat foods that are healthy for the brain and add “happy” to your mood?

Researchers at the University of Warwick in Coventry UK say “yes!”  The staff followed 12,000 adults from Australian households for six years.  Participants kept food diaries and answered survey questions about their lives as well as their mental and emotional health.  By the end of the second year, participants who changed from eating no fruits and vegetables a day to eight portions a day reported feeling happier.  Participants who did not increase their intake of fruits and vegetables over the same period experienced a drop in happiness score.  The “happy” power of fruits and vegetables was equivalent to going from unemployment to a job. (American Journal of Public Health, August, 2016)

Consuming eight servings of fruits and vegetables each day (about four cups) provides thousands of antioxidants and anti-inflammatory nutrients that improve brain function in measurable, mood-altering ways.

What about work?  Regardless of the wording (labor, exercise, work, or toil), the brain activates, controls, and evaluates movement.  Both psychologists and neuroscientists have independently addressed the theory that work ignites positive emotions.

Psychologists investigated a unique consumer issue called “The Ikea Effect,” that is, the consequences of buyers’ assembling items purchased.  The study concluded that assembling an item boosted feelings of pride, confidence, and competence even when the end product was poorly assembled.  It appeared that work, especially with the hands, activated the Reward Circuit.

Real-time imaging of the brain, conducted by Kelly Lambert, a neuroscientist, confirmed the conclusions of the Ikea study.  Dr. Lambert recruited persons with untreated depression and set up work projects, such as pottery-making, wood carving, or knitting.  She demonstrated that labor with the hands and arms activated the Reward Circuit, elevating positive emotions sufficiently to eliminate the symptoms of depression in her patients.  Dr. Lambert labeled the process as “effort-driven reward.”  Yes, work can be a happy experience.  And, when the effort is purposeful and helps others, the happiness rating is even higher. (“Lifting Depression” by Kelly Lambert, 2010)

Celebrate the Brain

Posted on Posted in Brain Science, Continuing Education, Homestudy, Nutrition, Psychology, Seminars, Webinars

fondue-709713_640Thanksgiving and the many holidays that follow are joyful times to be with family and friends.  Holiday cheer, a positive emotion, can also provide the brain with healthful hormones and neurochemicals that improve brain function.

Family traditions boost enjoyment of holiday gatherings.  In a recent series of studies in the Journal of the Association for Consumer Research, subjects described the customs they followed — along with those of their families — during holidays.  These activities were rated as enjoyable, personal experiences that enhanced bondings with family members.  In fact, simply recalling past traditions can put a warm glow on holiday gatherings and support creative thinking.

Memories of childhood or lost loved ones often surface at celebrations.  The bittersweet feeling of nostalgia can elevate mood and mental outlook.  A recent study published in the journal, Emotion, reported that nostalgia boosts a sense of connection to the past, creating a social web that extends across people and time.  This “self-continuity” energizes the brain.  So, pull out an old photo album and spend some time revisiting your past this season.

When listing New Year’s resolutions, resolve to keep friendships alive throughout the year.  The benefits of supportive relationships are numerous.  Research published online in the Journal of Epidemiology and Community Health (2016), stated that individuals who have greater levels of social support enjoy better psychological health and mental functioning.  The reduction of chronic stress and the stimulation associated with meaningful social interaction are strongly linked to improved resilience and reduced risk of anxiety and depression.  There is also a lower likelihood of cognitive decline.

The highlight of any holiday is food, often deeply entwined with tradition, but possibly devoid of brain-healthy choices.  Compromises that allow both brain-healthy and traditionally-happy fare, including desserts, can solve this dilemma.  First, shift the spotlight from rich food to lighter fare by serving salad as the first course.  Go heavy on the greens, colored veggies, and crunchy bits of apples or pears.  Second, make a healthy vegetable side dish the co-star of the main course.  Third, regarding the turkey, think outside the bread box with offerings such as wild-rice stuffing, augmented with vegetables and dried cranberries.  Lastly, the first bite of dessert, thoughtfully consumed, always gets rated as the best.

Enjoy the fabulous taste of that bite!  Then, empower your mind with oxygen — by taking a mindful walk — to complete the celebration of your brain.

Belly Fat and Movement

Posted on Posted in Continuing Education, Nutrition, Psychology, Seminars, Webinars

By Laura Pawlak, PhD, RD emeritus

Today, unlike any time in U.S. history, body fat is accumulating pointedly in the belly.  In addition to calorie restriction, what practice is required to decrease belly fat?  Move about.

Losing the unwanted pounds gained during the holidays is a struggle for everyone. Keeping it off is even more difficult.  What’s the best way to maintain a lower weight, once achieved?  Move about.

Scientist study the brain, searching for ways to keep it vital over the extra decades we now live. What is considered the most important lifestyle factor to retain cognition throughout life?  Move about.

More Americans are diagnosed with depression and anxiety than anywhere else in the world.  What habit can aid in balancing mood?  Move about.

Researchers agree that the most important natural way to bring about good health is movement.  During activity, muscles release anti-inflammatory proteins that act as a natural protection against disease.  In spite of the proof that moving is as vital as sleep, food, or water, less than 25 percent of the nation exercises.

Perhaps part of the problem lies in the mistaken vision of exercise as fitness training, often too tough for most mortals. Boutique gyms continue to augment the difficulty of their programs to retain the hardiest of their hard-core members.  While a few exercisers may enjoy the endorphin “high” produced by the physical demand of these classes, the average member is soon discouraged and disappears in about three months.

At the opposite end of the spectrum is the typical worksite, where the employee exercise program might be limited to moving one’s fingers on a computer all day. Scientific evidence clearly shows that sitting for long periods of time heightens the risk of dementia, diabetes, depression, and, of course, obesity.

Now imagine that your workplace offers a program that can lift your mood and combat lethargy without reducing focus or attention — and even dull hunger and cravings.  What’s the strategy?  Stand up and walk for five minutes every hour during the workday.  Whether you are hired, fired, or retired, this movement schedule is a healthy approach to limiting sedentary behavior every day.

Does a simple sit/walk program eliminate the need for strength training, stretching, and near-daily moderate exercise?  No, but it’s wise to begin an active lifestyle with the easiest step.  Devote five minutes of every sedentary hour to walking.
