Lower Your Diabetes Risk by 36%

A new study finds people who consume two servings of fruit per day have 36 percent lower odds of developing type 2 diabetes than those who consume less than half a serving. The research was published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

Diabetes is a disease where people have too much sugar in their bloodstream, and it is a huge public health burden. Approximately 463 million adults worldwide were living with diabetes in 2019, and by 2045 this number is expected to rise to 700 million. An estimated 374 million people are at increased risk of developing type 2 diabetes, the most common form of the disease. A healthy diet and lifestyle can play a major role in lowering a person’s diabetes risk.

“We found people who consumed around 2 servings of fruit per day had a 36 percent lower risk of developing type 2 diabetes over the next five years than those who consumed less than half a serving of fruit per day,” said study author Nicola Bondonno, Ph.D., of Edith Cowan University’s Institute for Nutrition Research in Perth, Australia. “We did not see the same patterns for fruit juice. These findings indicate that a healthy diet and lifestyle which includes the consumption of whole fruits is a great strategy to lower your diabetes risk.”

The researchers studied data from 7,675 participants from the Baker Heart and Diabetes Institute’s Australian Diabetes, Obesity and Lifestyle Study who provided information on their fruit and fruit juice intake through a food frequency questionnaire. They found participants who ate more whole fruits had 36 percent lower odds of having diabetes at five years. The researchers found an association between fruit intake and markers of insulin sensitivity, meaning that people who consumed more fruit had to produce less insulin to lower their blood glucose levels.

“This is important because high levels of circulating insulin (hyperinsulinemia) can damage blood vessels and are related not only to diabetes, but also to high blood pressure, obesity and heart disease,” Bondonno said.

Food Addiction

Food Addiction

Binge eating disorder was a diagnosis formulated in the Diagnostic Statistical Manual, 5th edition (DSM5) and represents a step forward towards the formal recognition of food addiction. This term itself is now rendered problematic by DSM5’s change from the term addiction to the term substance use disorder.

The advent of DSM5 has heralded a re-evaluation of the diagnosis of food addiction. The following criteria for food addiction have been proposed as modifications of the current DSM5 criteria for substance use disorder

1. Food often consumed in larger amounts or over a longer period than was intended

2. Persistent desire of unsuccessful efforts to cut down or control food intake

3. Great deal of time is spent in activities necessary to obtain or overeat on foods or recover from its effects

4. Craving, or a strong desire or urge to eat specific foods

5. Recurrent overeating resulting in a failure to fulfill major role obligations at work, school, or home

6. Continued overeating despite having persistent or recurrent social or interpersonal problems causes or exacerbated by the effects of specific foods

7. Important social, occupational, or recreational activities are given up or reduced because of overeating on foods

8. Recurrent overeating in situations in which it is physically hazardous

9. Overeating is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by overeating on foods

10. Tolerance defined as a need for markedly increased amounts of food to achieve desired effect or a markedly diminished effect with continued use of the same amount of food

11. Withdrawal defined as a withdrawal syndrome when refraining from eating specific foods or when specific foods are eaten to relieve or avoid withdrawal symptoms

The diagnosis of food addiction according to the above would require the presence of at least two symptoms, however, one of the criticisms of this rubric is the potential for overdiagnosis of food addiction, especially when one considers that non-obese patients who struggle with the cycle of overeating and dieting may endorse at least two criteria.

The Yale Food Addiction Scale version 2 (YFAS2) has been developed as a tool for the diagnosis of food addiction. It has thirty-five questions which are based on the current eleven substance use disorder criteria described by DSM5.

Obesity, food addiction and binge eating disorders can be seen to be closely related, but nonetheless distinct clinical entities each with their own diagnostic criteria.

Obesity is diagnosed when the body mass index is more than 30 kg/m2. Binge eating disorder is diagnosed when binges (consumption of large amounts of food in a limited time frame such as two hours) occur at least weekly for the last three months and where these binges are associated with a loss of control of eating and significant distress to the patient.

Using the YFAS2 the prevalence of food addiction in those with obesity ranges from 20-50%, in those with anorexia nervosa, 70% in those with anorexia nervosa, 80% in those with binge eating disorder and 95% in those with bulimia nervosa.

Therefore, the management of both obesity and binge eating disorder can be approached from the perspective of addiction treatment. Such paradigms already exist, e.g., “Food Addicts In Recovery Anonymous”. Whilst medication can play a role in the management of these conditions it is important to understand, identify and manage the underlying psychological issues that predispose to and perpetuate these food related behaviours. Failure to do so results in an ongoing cycle of emotionally driven overeating and self-loathing.

What is Lifestyle Medicine
Global Awareness, Healthcare, MedHeads

What is Lifestyle Medicine

The American College of Lifestyle Medicine defines lifestyle medicine as
“the use of evidence-based lifestyle therapeutic intervention—including a whole-food, plant-predominant eating pattern, regular physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connection—as a primary modality, delivered by clinicians trained and certified in this specialty, to prevent, treat, and often reverse chronic disease”

But what does it mean in practice? I think of lifestyle medicine as the management of chronic diseases within a socio-psycho-bio-medical framework that incorporates the three Fs and the three Ss.

What is the socio-psycho-bio-medical approach I hear you say?

This approach to chronic disease management considers all aspects of a person’s care including social supports, psychological therapies, biological therapies and medical interventions. It emphasises the role of lifestyle but does not replace or exclude appropriate pharmaceutical or surgical management of chronic diseases.

What are the three Fs and the three Ss? They are the following.

Feet
Fork
Fingers

Sleep
Stress management
Socialisation

Feet
Feet reminds us to consider exercise as a lifestyle medicine intervention. It is recommended for most adults that they engage in at least 150 minutes of brisk walking (or equivalent exercise) per week.

Fork
Fork reminds us to consider diet as part of a lifestyle intervention. As per the definition above, a lifestyle medicine practitioner would recommend a whole-food, plant-predominant eating pattern to maintain a normal weight and nutritional balance.

Fingers
Fingers remind us to consider abstinence from cigarettes and other illicit drugs. They also remind us to limit alcohol intake to no more than ten units per week and no more than four units on any given day.

Sleep
This reminds us that most adults need between seven to nine hours of sleep per night. The days of the sleep-deprived hero are over. Evidence now demonstrates the health benefits of a good night’s sleep which one dismisses at one’s peril.

Stress
Stress is known to contribute to and exacerbate the burden of chronic disease. Stress management interventions should be incorporated into any lifestyle medicine plan of care.

Socialisation
Socialisation reminds us that we are social animals designed to engage positively, purposefully, and meaningfully with our tribe. Loneliness is now known to affect chronic diseases and put us at risk of premature death. Treating loneliness and encouraging the development of positive, purposeful, and meaningful social networks is an important part of a lifestyle medicine plan.

A Difficult Conversation

A Difficult Conversation

A Difficult Conversation

I hate seeing other doctors regular patients. They have expectations of clinical behaviour of which I am totally ignorant. This lady was no different. I had never met her before. She was middle aged. She ran her own cleaning company.

She breezed in and said to me that phrase that I dread.

“I normally see Dr…This will be quick, I just need a prescription.”

So the conversation went something like this.

“Hello, my Name is Dr Armstrong. How can I help you.”

“Well, I just told you, I just need my usual script.”

“What usual script.”

“I just need my usual Panadeine Forte.”

“may I ask why you need Panadeine Forte?”

“I take it two to three times a week when I cannot sleep. I don’t abuse it. Dr… always gives me some.”

I checked safe script. She was right. Dr … was regularly prescribing it. There were no red flags against her safe script record. It appeared that Dr…was prescribing only small quantities of the drug and no alarms had been triggered in the SafeScript software.

I then asked her, “So you use it to help you sleep, is that right?”

“Yes, I’ve just told you, now please give me the prescription. I am in a hurry.”

She then looked at her watch meaningfully.

I explained to her that I felt that it was my role to manage her appropriately and safely. I explained that I felt that her use of codeine was inappropriate and that it could lead to dependency. I offered to help her deal with her insomnia in a more holistic way.

She then said, “Look Doc. You are being difficult. Are you, or are you not going to prescribe Panadeine Forte for me. Or do I have to go to Dr…?”

I replied, “No I am not.”

“Well you’re a useless waste of space then aren’t you!”

She walked out. An hour later she saw the other doctor. At least he came to me to let me know that he had prescribed for her, on the grounds that her use was not excessive and that a year ago she could have bought it over the counter.

Unlocking the Path to Health

Unlocking the Path to Health

On MedHeads show this week

This week I chatted with Aileen Thoms about health promotion and lifestyle medicine.
Aileen has a master’s degree in health promotion and is the director of primary health and innovation at a regional health service. She has a passion and a wealth of experience and expertise in this sometimes-neglected area of health care. As she says, an ounce of prevention is better than a pound of cure.

We discussed the following issues.

The definition of health

Aillen feels that one’s definition of health needs to be contextualised, for instance health can mean body beautiful to a young person but could mean being able to do gardening pain free to an elderly person.

The determinants of health

Poor health has been shown to be associated with low social economic status, ethnicity, cultural background.

The difference between a proximal and distal determinant of health

It is important to understand the difference between a proximal versus a distal determinant of health. For instance, a plane crashes because it loses lift and gravity pulls it out of the sky. That is the proximal determinant of the plane crash. However why did the plane lose lift? Well, it could be the case that there was an engine malfunction because the engineer made a mistake during the last scheduled maintenance, because he did not sleep well the night before, because he had a fight with his wife the evening before. These factors are all more distal determinants of the plane crash. Similarly, in the context of disease, it is important to ask the question why.

For instance, people from lower socio-economic classes smoke more. But why? Is it because they have lower levels of health literacy? But why? Is it because they do not speak English well? But why? Is it because they come from a culturally and linguistically diverse background? But why? Is it because people from these backgrounds are not adequately supported by health policy? Asking why helps us all to consider the distal determinants of health.

The six pillars of lifestyle medicine

We discuss the six pillars of lifestyle medicine which are: the feet (exercise); the fork (diet); the fingers (smoking cessation, alcohol in moderation and abstinence from illicit drugs); sleep (we all need seven to nine hours sleep per night); stress management (stress is known to cause a wide range of diseases); and socialisation (we all need positive rewarding and nurturing relationships).

The changes that can be made to improve one’s lifestyle

Within the above construct we all can make small changes which, if applied consistently, will provide benefits to our health in the long term. These could include walking more, eating less processed food and eating more vegetables, cutting down on alcohol, and going to bed earlier.

The barriers to change and how to overcome those barriers

It is not enough to know what to do, but rather we need to do it. Sometimes people may feel overwhelmed by what they perceive as an insurmountable challenge such as “lose ten Kgs”. The trick is to break the task down into a series of smart goals. These goals should be specific measurable achievable relevant and time bound. The longest journey starts with the smallest step. All we need to do on a daily basis is take the next step towards a healthier lifestyle.

Skin Integrity

Skin Integrity

This week on MedHeads I spoke with Zoe Lance about skin integrity.

Skin is the largest organ od the body and serves many functions including its physical barrier function, the prevention of infection, the regulation of body temperature and sensation. As skin ages skin loses its collagen content. Chronic sun exposure can also contribute to skin aging. The net effect of this is skin thinning, reduced elasticity and reduced wound healing.
The moisture content of skin is also important.

The optimal water content in skin is about ten per cent. Both too much moisture (causing skin maceration) and too little moisture (causing dry skin) in the skin can reduce skin function. Air is dryer in the winter when air is colder and less able to store water vapour, and also dryer in houses with central heating so skin tends to lose moisture in these conditions.

Dry skin needs to be moisturised at least once a day, if not three times per day. Dry skin is also more sensitive to the irritant effects of soap. Managing skin integrity also involves making sure that skin folds are not damp, because this can cause skin to become macerated and then ultimately infected. Nails need to be kept short and web spaces need to be dried after washing to prevent the risk of fungal infection.

Skin needs to be inspected regularly, not only for overall integrity, but also for blemishes and lesions that need to be checked out by a doctor. Pressure areas such as the elbows, knees, the lower back and the buttocks need special attention. The first sign of a pressure sore is a red rash developing over these pressure areas. Moisturising the skin and offloading the affected area can prevent an ulcer.

Skin in the pelvic region is particularly vulnerable to the effects of incontinence. Urine is generally acidic so exposure to skin to urine can cause chemical irritation which in turn can lead to loss of barrier function, infection, and ulceration. Incontinence needs to be managed appropriately and pelvic skin needs to be protected with thick barrier creams.

Finally, just like us, our skin needs to be fed and watered adequately. Attention to nutrition and hydration is important for our general health as well as our skin health.

Sleep Phase Disorder
Global Awareness, Healthcare, Lifestyle Matters, MedHeads

Sleep Phase Disorder

This week on Lifestyle Matters  I talked with Dr Saveena about sleep phase disorder.

Our natural sleep wake circadian rhythm does not usually last exactly 24 hours. Some people have an earlier sleep phase with a circadian rhythm that lasts less than 24 hours, whereas some people have a later sleep phase with a circadian rhythm that lasts longer than 24 hours. People with a shorter than 24-hour sleep phase are the typical morning larks that jump out of bed in the morning with boundless energy and people who can stay up all night partying are the night owls.

Re rely on zeitgebers (environmental time cues) such as the circadian day night cycle to entrain our sleep wake cycle to the length of a standard day, i.e., 24 hours. Nonetheless some people experience difficulties with such entrainment, and problems can occur, usually at the extremes of age.

Teenagers have difficulty getting up in the morning, but enjoy staying up late at night, and they can be considered to have delayed sleep phase disorder, whereas it is common for elderly patients to wake up too early in the morning and they can be considered as having advanced sleep phase disorder.

The administration of melatonin in the evening, in conjunction with early morning light exposure can help people with delayed sleep phase disorder. The administration of melatonin in the morning in conjunction with morning darkness can help people with advanced sleep phase disorder.

Jet lag is also a form of sleep phase disorder. It usually occurs when we cross five or more time zones. When we travel eastward, we chase the sunrise and experience delayed sleep phase disorder, i.e., we feel awake when everyone else is trying to get to sleep. Light exposure in the early part of the day at the destination and melatonin in the destination’s evening will help. When we travel westward, we chase the sunset and experience advanced sleep phase disorder, i.e., we want to go to bed when everyone else is still awake. Exposure to bright light in the late afternoon and evening will help us stay awake until a more reasonable bedtime

Transition Care Programs
Global Awareness, Healthcare, Lifestyle Matters, MedHeads

Navigating Transition Care Programs (TCP)

The transition care program

Today I spoke with Zoe Lance, RN, about the transition care program, otherwise known as “TCP”. TCP can be conceptualised as a half-way house between acute care and being able to manage safely at home. The gateway to TCP is the aged care assessment, without which a TCP referral cannot be accepted. Referrals are usually received from acute hospital settings or from geriatric evaluation and management (GEM) services.

There are broadly two streams of TCP, a residential stream and a community stream. The determination of which stream a patient enters depends on the initial TCP assessment of function. For instance, patients who are unable to weight bear would not be deemed as suitable for community TCP but would be directed to residential TCP.

Residential TCP can provide 24 hours per day nursing and care support for patients in a residential care setting. Factors that suggest that a Patient would be deemed as fit for community TCP would include that fact that the patient would be weight bearing.

Services that can be provided for community TCP patients include visits by district nurses, the provision of personal care and the provision of services such as meals on wheels.

All TCP programs have stated goals of care. These are the functional goals that the patient would be expected to manage at the end of a twelve-week program. These can include being able to manage all activities of daily living (such as dressing bathing showering toileting and feeding) and managing medication safely.

Whilst both these services are heavily subsidised patients are expected to contribute approximately $10.85 for community-based TCP services and $52.71 for residential TCP services. The patient’s contribution to residential TCP services is similar to that payable for residential respite services.

Solution Focussed Therapies

GPs have a role in providing mental health treatments and should bear in mind that talking therapies have as good if not better levels of success than pharmacological approaches and they have no side effects. Efficacy without side efficacy! What’s more there is no possibility of physiological dependency and therefore no withdrawal syndrome.

For talking therapy to be effective both the practitioner and the patient need to be in the moment. But what does that mean? It can mean that your mind, body and soul are in harmony, that your full attention is in a specific place and time i.e. in the therapy space.

This can be formalised explicitly – as in Acceptance and Commitment Therapy, or implicitly – as in Solution Based Brief Therapy.

Either way, you should not be sitting in the therapy space whilst thinking about having a coffee with a friend or what you will eat for dinner. Another way of describing it is getting rid of your internal dialogue. If a stray thought pops up, and they will, then let it go and then refocus your attention back to that therapy space.

Solution focussed therapy does not dwell on the past, but rather works from a premise that the future is negotiable. Solution Focus is not so much a set of therapeutic steps as a way of communicating with the patient and letting them open their own eyes to their own functional solution to their problem. Knowing the problem or engaging in analysis is quite unimportant.

So, what is the process?

Well, it begins by asking the patient.

Actually ask the patient how they want to live their lives, don’t tell them how to do it. Admonishment as therapy is so twentieth century!

Ask your patients what is better since they last saw you. Ask them what their “exceptions” were that show their suffering is not entirely constant. Ask them if they can be complimented on anything. Was there anything that the patient handled that was challenging, that they coped with when others would have crumbled. These complements are reflections on the resilience, coping and values of the patient. Ask them what their hopes are for the session you have with them that day.

Self-knowledge

Sun Tzu said “If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.” Sometimes therapy can feel like a battle of wills, but it should not be seen thus. Rather it can be a space wherein both the patient and the therapist achieve an in depth understanding of the patient’s strengths and weaknesses, their ideas concerns and expectations and their concept of purpose. With this understanding the levers of change can be engaged. The patient needs to see where their own levers are, so they can use them to effect meaningful change. The therapist is not trying to win but trying to coach the patient to develop their own self efficacy, their own hope and ultimately to win their own battle.

A useful question to ask in this context is “what are they good at”? what would a significant other/close friend/child/colleague say they were good at? Third party perspectives can be more powerful in unlocking this truth, and it can sometimes be useful to ask this question about someone whom the patient fears or does not like. With this question we get an idea of the connections the patient may have with other people and question provides an opportunity for the patient to consider themselves within the context of a family, a tribe and society.

The miracle question

The miracle question is also a useful tool to unlocking the potential for change. IT is a question designed to evoke a detailed vision of their desired future.
The question might be phrased as follows.

“So, you go to bed tonight and you don’t know it happened, but during the night a miracle happened and all the things that brought you here today just dissolved. What would be the first clue that the miracle had happened? What would someone else see hear or feel? What would they see you do?

It is important to drill down, get detail, about what their desired future would look like on day one.

Follow up questions might include the following.

What would you do differently?
What would you still do?

And the line of questioning could then be brought back to bear on the present by asking such questions as “Could you do something different now, as if the miracle had happened? Would you be prepared to try?”

Having a dream, a hope, and noticing that the problem is not there all the time (exceptions caused by a degree of agency) works towards them determining the small steps required to get big results.

Dead men’s goals

When considering solution focussed therapy and change management it is important to recognise and avoid dead men’s goals. An example could be “to not drink”. These goals are so called because the dead don’t drink. Rather, it is more engaging and beneficial to use the instead” question. An example might be “So what would you do instead of drinking?”. And an answer might be “I’d spend more time playing with my kids.”

The power of the right question ta the right time delivered in the right context should not be underestimated.

The image below represents a starting point on the journey a therapist takes with a patient towards successful change management and recovery.

The Fed and Fasted State
Global Awareness, Healthcare, Lifestyle Matters, MedHeads

The Fed and Fasted State

On Lifestyle Matters Saveena and I chatted about the hormonal regulation of the fed and fasted state.

When we eat we ingest carbohydrates, proteins and fats, these are broken down by the digestive system into glucose, amino acids and triglycerides. These substances are then absorbed by the body. Therefore, In the fed state our bodies are full of sugar that needs to go somewhere. Insulin is secreted by the pancreas in response to two signals. Firstly the presence of food in the gastrointestinal tract triggers the gut to secrete incretin hormones (GIP and GLP-1) which in turn triggers the pancreas to secrete insulin. Secondly the presence of glucose in the blood stream also stimulates the pancreas to secrete insulin.

Insulin is the main storage hormone in the body and as such acts to “bring in the harvest. It has three main actions. Therefore, it limits the sugar high that occurs after eating.

It stimulates the liver to convert glucose to starch (also known as glycogen). Secondly it acts to trigger the conversion of amino acids to proteins, and thirdly it stimulates fat cells to convert free fatty acids into fat, a process known as lipogenesis.

When the liver’s glycogen stores are saturated then insulin directs excess glucose towards the production of fat, hence insulin is known as the “fat hormone”.

After a couple of hours, the glucose rush abates, and our glucose levels drop. We then enter the fasting state. At this point a different hormone comes into play. Glucagon, also secreted by the pancreas, is released in response to a low blood glucose and stimulates the liver to convert its glycogen stores back into glucose. This then maintains the body’s constant level of glucose in the fasted state. The liver however has a limited supply of glycogen that can be broken down into glucose. When glycogen stores run out another hormone, growth hormone, acts to trigger fat cells to release their stored energy in the form of glycerol (which can be converted into glucose) and free fatty acids, which can be used as an alternative energy store.

Growth hormone also acts to stimulate protein synthesis, which provides a survival benefit. When we are in a prolonged fasting state growth hormone causes our bodies to preferentially burn fat and preserve muscle, allowing our ancestors to hunt and gather, and allowing us to drive and go shopping.

Therefore, it can be seen the both the highs and lows of glucose as we progress between the fed and fasted state are tightly regulated by the opposing actions of insulin in the fed state and glucagon and growth hormone in the fasting state.

Appetite is also regulated hormonally. Our empty stomachs secrete a hunger hormone, ghrelin which stimulates us to eat. After eating ghrelin secretion reduces. Food then stimulates insulin secretion, which in turn causes our fat cells to secrete leptin which acts to trigger our brains into thinking we are full. Therefore, appetite and glucose is closely regulated by the interaction of hormone sin our body. In obesity however, leptin secretion is increased, but despite the higher levels of leptin circulating in our bodies the leptin signalling is blunted, the body does not recognise the “I am full” message. This lack of satiety messaging, despite higher-than-normal levels of leptin, is known as leptin resistance, one of the hormonal hallmarks of obesity.
