Bananas: Fruit of the Zoom
Endurance athletes have long known about the power of the banana. Unlike certain other snacks that dump high levels of sugar into the bloodstream right away, bananas give a steady supply of sugar as it is needed, and are a great source of potassium which is essential in the prevention of cramps. Competitive cyclists are therefore often seen with the ubiquitous yellow fruit poking out of their back pockets as they set off on long haul training rides.
However hard core athletes are not the only people who can benefit from the humble banana, and its health benefits are legion.
As well as containing fiber, bananas are a source of sucrose, fructose, and glucose which are natural sugars. Therefore the sugar goes into the bloodstream immediately but does not dump all of it in at once, giving a sustained and substantial boost of energy. Research has proven that just two bananas provide enough energy for a strenuous 90-minute workout.
As well has helping us power our engine as we keep fit, bananas can also help overcome or prevent a substantial number of illnesses and conditions.
According to a recent survey undertaken among people suffering from depression by MIND, a British mental health charity, many felt much better after eating a banana. It is known that the fruit contains tryptophan, a type of amino acid that the body converts into serotonin, known to make you relax, improve your mood and generally make you feel happier.
The yellow wonder is a source of vitamin B6 which regulates blood glucose levels, which can affect your mood and alleviate stress. Because they are rich in iron, bananas can stimulate the production of hemoglobin in the blood and so helps in cases of anemia. This unique tropical fruit is extremely high in potassium yet low in salt, making it perfect to beat blood pressure. Indeed the FDA allows the banana industry to make official claims for the fruit’s ability to reduce the risk of blood pressure and stroke.
In a study in a school in England, two-hundred students ate bananas for breakfast, at break time and lunchtime in a bid to boost their brain power. Research has shown that the potassium-packed fruit can assist learning by making pupils more alert.
Because they are high in fiber, a diet that includes bananas can help restore normal bowel action and alleviate the need for laxatives.One of the quickest ways of curing a hangover is to make a banana milkshake sweetened with honey. The banana calms the stomach and, while the honey builds up depleted blood sugar levels, and the milk soothes and re-hydrates your system.
Bananas have a natural antacid effect, and can help to relieve the pain of heartburn. Snacking on bananas between meals helps to keep blood sugar levels up and avoid morning sickness.
Many people bitten by mosquitos have reported that rubbing the affected area with the inside of a banana skin, rather than using an insect bite cream, reduces swelling and irritation.
Bananas are high in B vitamins that help calm the nervous system. Studies at the Institute of Psychology in Austria found that work-related stress leads to gorging on unhealthy snacks and processed “comfort food.” In a survey of 5,000 hospital patients, researchers found a correlation between obesity and high-pressure jobs. The report concluded that, to avoid panic-induced food cravings, snacking on high carbohydrate foods every two hours can help to keep blood sugar levels steady.
The banana’s soft texture and smoothness means that it lends itself to the treatment of intestinal disorders such as ulcers. The only raw fruit that can be eaten without distress in cases of chronic ulcers, it neutralizes over-acidity and reduces irritation by coating the lining of the stomach.
In many cultures the banana is seen as a ‘cooling’ fruit that can lower both the physical and emotional temperature of expectant mothers. Pregnant women in Thailand eat bananas to ensure that their babies are born with a cool temperature.
When compared to an apple, the banana has four times the protein, twice the carbohydrates, three times the phosphorus, five times the vitamin A and iron, and twice the other vitamins and minerals. It is also rich in potassium and is one of the best value foods around.
To cap it all off, it comes in easy-to-open, biodegradable packaging in a cool yellow color which is also smart enough to indicate the state of the fruit inside. The skin indicates that it is not ripe enough yet with a green signal, the optimum time to eat it is signaled with a pattern of brown speckles on yellow, and a banana out of date turns a solid brown. What’s not to like?
A Professional Dietitian’s Take on Weight Loss
Melissa Burton, based in Pasadena, is a woman of many talents. Owner of the website thevalentineRD.com, she also is a Registered Dietitian (RD), Certified Diabetes Educator, and holds a Certificate in Adult Weight Management (CDE) from AND.
In addition to her expertise in nutrition and as a diabetes educator, Melissa has a certification in weight management, but she does not consider her specialization to be weight loss. “My objective as an RD is to educate people about food and nutrition and to help them recognize their eating patterns,” she says. “Many people seek the counseling of an RD to lose weight, but weight loss is not only about calories in versus calories out and eating ‘healthy’ foods. People eat not just to sustain life in the metabolic sense, they eat for many more reasons than sustenance.” She maintains that there is always an emotional, social, financial, educational and lifestyle component to why, what, when, how and how much people eat.
To help her patients and clients lose weight without restricting calories, she tries to educate people about food and take the demonization out. “In my mind there are no ‘good’ or ‘bad’ foods just like you are not ‘good’ or ‘bad’ if you eat certain foods,” she says. “There is a place for every kind of food that someone likes in a healthy lifestyle. There are some foods that are healthier than others and I encourage people to eat foods that are as close as possible to how they were when they either came out of the ground, or off a tree, or with minimal processing.”
Teaching people what carbohydrates, proteins and fats are can be very eye opening to people. Melissa believes that that learning to read food labels, and noticing the number of ingredients listed on food labels, can allow people to make educated empowered choices about the foods they choose to eat.
In her experience, restriction of any kind such as calories and specific foods creates what she calls the ‘boomerang’ or ‘Hoover’ effect. “The chronic sense of deprivation sends someone from being strictly adherent to what they’ve been avoiding to doing the absolute opposite,” she says. “They Hoover or vacuum up the thing they’ve been avoiding and they cannot stop. Finding a way to include foods that are considered ‘triggers’ or ‘slippery slope’ foods is also very important in achieving a heathy eating mindset. Helping people to gain confidence in their own abilities to choose foods or give themselves permission to eat foods formerly considered ‘bad‘ are major steps toward a lifetime of healthy eating and living versus the ‘I need to diet to lose weight’ mentality.”
We need to eat multiple times a day just in order to live. There are people who eat to live and others who live to eat. Melissa believes that a healthy lifestyle can be a blend of both. “My nutrition practice speciality is women’s health,” she says. “I find that many women become interested in nutrition beyond the vanity phase before and during pregnancy. This is a time when women are open to learning about nutrition and when special attention to the growing of another human being, or two, is of the utmost importance.”
When asked if there are any specific foods that assist with weight loss, she says that there are not any specific foods per se, but consuming adequate fiber in the diet can certainly help with satiety and regular elimination of solid waste. “Fiber requirements for women are 25g per day and 38g per day for men,” she says. “The average American does not meet this with daily intake. Many nutrient-dense plant-based foods like fruit and vegetables are high in fiber so in the effort to lose weight, I do advocate fruit, vegetables, beans, whole grains and water. This is because in addition to increasing nutrient intake these foods increase fiber intake and help people feel full for longer. If people do not properly hydrate, the increased fiber can lead to constipation. With fiber one always needs adequate hydration of at least 30 ml per kg body weight, more if exercising or depending on climate.
Melissa does not generally recommend dietary supplements for people who want to lose weight. “However,” she says, “if one’s intake does not meet all of the daily vitamin and nutrient needs sometimes a multivitamin may be in order. Also asking your doctor to check at blood draws for nutrient deficiencies such as Vitamin D, B12, or calcium (especially for women) may help optimize metabolism with supplements if nutrient deficiencies are detected.” A multivitamin can often act as an appetite stimulant in those with long term poor intake history. Once the body receives missing nutrients on a regular basis, it often begins to give signals of hunger to replete stores.
While for some people hormone imbalances may be hindering their weight loss efforts, stress, sleep and intake patterns can also have an effect on weight loss efforts. If stress, sleep, intake changes and exercise do not have positive effects on weight loss, she recommends a blood work panel to check thyroid hormones, insulin levels, or in women to test for androgens (male hormones) that may play a part in PCOS (Polycystic Ovary Syndrome) which all may prevent expected weight loss.
The most important piece of advice she can give to someone that wants to lose weight is to find a way to make healthy eating a part of one’s lifestyle, not just go on a diet. “As an RD, I hate that my professional title has the words ‘die’ and ‘diet’ within a helping profession,” she says. “However, I am proud to be a Registered Dietitian Nutritionist (RDN, the newest term for RDs) because we are the nutrition experts. Anyone in the world can call themselves a Nutritionist but Registered Dietitian Nutritionists (RD or RDN) have standardized formal and practical education requirements that need to be met before being eligible to take and pass the Registered Dietitian exam.” Indeed, RDs and RDNs must also take 70 continuing education credits every five years to keep themselves in good professional standing.
Melissa adds, “Most people know that exercise, healthy eating, sleep, moderate stress and proper hydration are keys to losing weight but what we eat and the way we live is more than the sum of science. It’s imperative that someone starting on weight loss journey find their own measure of support, patience and the willingness to learn.” She maintains that it is important not to let the pills, cleanses and diets promising a new body, and a new life, play upon one’s insecurities.
“Your mind is the most important part of a weight loss effort,” she says. “With nutrition education comes empowerment and the beginning of a healthy lifestyle on one’s own terms.”
Helping Women to “Age Actively”
Santa Barbara-based Alexandra Williams, along with her twin sister, Kymberly Williams-Evans, has an infectious energy that has been a feature of their active lives almost from the day they were born. Raised by a mother who taught modern dance, they spent many childhood years acting and dancing in musical theatre. In their teens they took up soccer, and in 1982 Kymberly went to Germany to teach English and dance, only to discover a studio that taught a new type of movement called aerobics. Alexandra promptly joined her in the still-divided city. “Aerobics was all high impact and leg warmers,” she says. “We did a weekly exercise show on the military channel there, plus taught at the first Berlin aerobics studio.”
Alexandra wanted to study Russian language and literature, so she moved back to the States and started teaching exercise classes locally in order to support herself. “Little did I know I’d still be teaching and traveling the world with fitness thirty years later,” she says. “I teach in the Exercise Studies department at UC Santa Barbara. Besides that, I work on our blog FunAndFit.org, which is geared toward boomer women who want to age actively, I write for print magazines, I co-host a radio show, and I mentor new instructors. I also compel my boys to walk the dogs with me.”
A frequently-asked question put to Alexandra and her sister is where to start if someone wants to lose weight. Her answer begins with a question, “What’s the least you can do?” She says that it sounds counter-intuitive, but “usually people make a grand, general plan, say, I want to lose 50 pounds, yet have no idea what the small steps are to get to the end goal.” Her advice is to make a list of the ten steps needed to get from 1 (where you are now) to 10 (50 pounds lost). “The steps must be measurable, specific and realistic.” They have written blog postings to flesh this out in more detail.
When asked for tips for someone who doesn’t have access to a gym, she rubs her hands together. “But of course,” she says. “If you can get outside, walk around the block. Having said that, I live on a mountain, so a walk around the ‘block’ would take a few days! You can do lots of movement in your house – pushups against the kitchen counter, sit-to-stand squats while watching television or sitting down to dinner. You start to sit, then stand back up, then sit. Do this every time you go to sit down and you’ll have added a lot of squats to your day.” She adds that rudimentary weights can be made out of five pound bags of rice for bicep curls, or to perform ab crunches. Even a can of tuna can be enlisted (see video).
When asked for the best exercise for those with over 20 pounds of fat to lose, Alexandra’s answer is simple. “The one you’ll do.” Sometimes people want to know the quickest, or most effective when they say “best,” but the truth is “an exercise is only effective if you do it. So choose one you’ll enjoy, or at least do. Having said that, if someone is trying to lose 20 pounds in a hurry, they are best off with High Intensity Interval Training. But if the extra 20 pounds is hard on the joints, this type of training is contraindicated.”
Alexandra is often asked who her fitness mentors are and why, and her answer is consistent. “My mom was a modern dance teacher with five young kids, yet she found a way to teach dance and include us. So she instilled a love of movement in me. Then my twin sister Kymberly and I went from playing college soccer to teaching aerobics back when it was new. My sis was the one who convinced me to move to Berlin and start teaching over thirty years ago, so that worked out rather well.” There are some industry professionals that she really likes because they offer “fun, safe and effective workouts,” but they did not mentor her.
A lot of people start exercising regularly, but still struggle to lose some extra pounds. In Alexandra’s experience, the key factors that prevent people from losing weight despite regular exercise are that they probably have not changed their eating or sleep habits. “If you exercise intensely for an hour and manage to burn 600 KCals, then drink a frou-frou coffee drink, you just drank back those 600 KCals in three minutes, which is very disheartening. On the bright side, people who start including strength training as part of their routine may gain weight as they build muscle, yet will find their clothes loose-fitting.” She advises people to dump the scale “unless using it to do overhead presses!”
Hormone imbalances may hinder people’s weight loss efforts, particularly during menopause, and tests can be preformed to diagnose the imbalances. Alexandra recommends her colleague Tamara Grand, a personal trainer and fitness author who has a whole series on this.
Any training regimen that can be offered to a client who says they strictly wants to lose weight depends on the client’s history, schedule, motivation, “and how many delicious snacks she brings me!” In general, Alexandra recommends starting with:
- Short duration, high intensity (not necessarily high impact) cardio
- Strength training (higher amount of weight, fewer repetitions)
- Cutting portions by a third
- Getting at least 7 hours of sleep nightly (your body recovers and is not awake eating)
She says that these may seem “boring, yet are extremely effective.“
When asked about how much weights versus cardio women in their forties should do, Alexandra laughs. “They are friends,” she says, “so there is no ‘versus.’ They need to work together. A woman in her forties needs to do both. How much, how often, how long, and what type depend on the woman, but a good place to start is 50/50. If she is a new exerciser, then three days a week, 60-90 minutes at a time is a good place to start. And ladies, go big. You are not doing bodybuilding (unless you really are), so you aren’t going for one rep maximum. You are going for health, energy and looks, right? So work up to at least 8-10 pound barbells in each hand if you are using free weights.”
When one is trying to lose weight or get in shape, goals are all important, so what should they set out to accomplish, and what would be a healthy time frame to to accomplish the goal of losing 20 pounds?
“Follow the ten-step outline I mention above,” she says. “If you don’t write down specific steps, you have no idea how to get to your end goal. And it’s best to lose 1.5 – 2 pounds per week. If you diet and lose lots of weight quickly, that’s exactly how fast you’ll gain it back. How long did it take to put on those 20 pounds? Yeah, frustrating. But healthy and realistic. And remember, the goal is to lose weight and keep it off, not lose it repeatedly.”
Good advice.
