Nutritional Supplements for Joint Health

The health of our joints is essential for maintaining an active and fulfilling lifestyle. However, as people age, joint problems such as osteoarthritis, rheumatoid arthritis, and general wear and tear become more common. In this context, dietary supplements have gained popularity as a means to support and enhance joint health. This essay delves deeper into the various supplements available and their efficacy in maintaining and improving joint health, with a focus on providing more detailed insights into each supplement.

Glucosamine and Chondroitin

Glucosamine and chondroitin are natural compounds found in the cartilage of our joints, and supplementing with these substances aims to provide the body with the essential building blocks for joint repair and maintenance. While numerous studies have explored the potential benefits of glucosamine and chondroitin, results have been mixed. Some research suggests that these supplements may reduce pain and improve joint function in individuals with osteoarthritis (Houpt et al., 1999). However, it’s important to note that not everyone responds equally to these supplements, and more studies are needed to determine their full efficacy.

Omega-3 Fatty Acids

Omega-3 fatty acids, primarily found in fish oil, have gained attention for their anti-inflammatory properties, which can help reduce joint pain and stiffness. In particular, these fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been shown to decrease inflammation in the body. This can be especially beneficial for individuals with rheumatoid arthritis, as inflammation plays a central role in this condition (Goldberg & Katz, 2007). Omega-3 supplements may also have a positive impact on individuals with osteoarthritis, although individual responses may vary.

Turmeric and Curcumin

Turmeric, a bright yellow spice commonly used in Indian cuisine, contains curcumin, a potent anti-inflammatory compound. Curcumin has been the focus of numerous studies for its potential to alleviate joint pain and improve symptoms of arthritis. A comprehensive review of clinical trials by Daily et al. (2016) suggests that curcumin supplementation may reduce pain and improve function in individuals with osteoarthritis and rheumatoid arthritis. Curcumin’s anti-inflammatory properties are believed to play a significant role in reducing joint discomfort and enhancing overall joint health.

Methylsulfonylmethane (MSM)

Methylsulfonylmethane, or MSM, is a naturally occurring sulphur compound found in various foods like fruits, vegetables, and grains. MSM is believed to support joint health by contributing to the maintenance of the cartilage and connective tissues. While the research on MSM is somewhat limited, a study by Kim et al. (2006) demonstrated that MSM supplementation could significantly improve joint function and alleviate pain in individuals with osteoarthritis. It is worth noting that MSM may work synergistically with other supplements or therapeutic approaches to enhance overall joint health.

Collagen

Collagen is a structural protein that is essential for the integrity of our joints, as it forms a major component of joint cartilage. Collagen supplements are believed to help maintain joint integrity and reduce joint pain. A study conducted by Zdzieblik et al. (2017) found that collagen supplementation significantly improved joint function in athletes with joint discomfort. However, more research is needed to establish the full extent of collagen’s benefits for the general population, as individual responses may vary.

Vitamin D

Vitamin D is crucial for calcium absorption, which is vital for maintaining bone and joint health. Inadequate vitamin D levels have been associated with an increased risk of osteoarthritis and other joint disorders (Haugen et al., 2018). Therefore, maintaining adequate vitamin D levels through supplementation may play a significant role in preserving joint health, especially for those at risk of deficiency due to limited sun exposure.

Boswellia Serrata

Boswellia serrata, also known as Indian frankincense, contains anti-inflammatory compounds that can reduce joint pain and inflammation. Research has suggested that boswellia extracts may be effective in managing the symptoms of osteoarthritis and rheumatoid arthritis (Ammon, 2006). These compounds work by inhibiting specific enzymes that contribute to inflammation, making them a potential complementary therapy for joint health.

Ginger

Ginger, a common spice with anti-inflammatory and analgesic properties, has been recognised for its potential to alleviate joint pain. Several studies have indicated that ginger supplementation can reduce pain and improve joint function in individuals with osteoarthritis (Bartels et al., 2015). Ginger contains gingerol, a bioactive compound with anti-inflammatory effects, making it a natural option for supporting joint health.

Conclusion

Maintaining healthy joints is crucial for an active and pain-free life, particularly as we age. While dietary supplements can be a valuable addition to a joint health regimen, it is essential to consult with a healthcare professional before incorporating new supplements into your routine. The effectiveness of supplements may vary from person to person, and their use should complement other measures like a balanced diet, regular exercise, and maintaining a healthy weight. In the pursuit of joint health, a holistic approach that combines these elements can lead to the most positive and lasting outcomes.

Eating For Health And Longevity

Valter Longo et al. recently published a paper that examined research on the relationships between nutrition, health and longevity. Here are some of the main components of a longevity diet:

• mid to high carbohydrate intake (45-60%) – mostly non-refined
• fat intake (25-35%) – mostly plant-based
• low protein intake (10-15%) – mostly plant-based but includes regular consumption of peso-vegetarian-derived proteins. Low protein intake or normal protein intake (with high legume consumption) lowers the intake of amino acids such as methionine. This in turn lowers pro-aging substances such as GHR, IGF-1, insulin and TOR-S6K.
• over 65s need to be careful to avoid malnourishment and prevent frailty and diseases resulting from reduced muscle mass, reduced bone mass or low blood cell count.
• the largest gains in longevity come from diets rich in legumes, whole grains and nuts. With reduced amounts of red meat and processed meats
• a 12-13hr daily fasting period is key to reducing the insulin resistance that may have developed from a high calorie diet. The fasting window also helps decrease levels of IGF-1, lowers blood pressure, lowers total cholesterol and decreases inflammation.
• our daily food intake should be established by our body fat/lean body mass composition rather than generic pre-set calorie amounts.

Higher Fibre Intake Improves Health

Last month Reynolds et al. published an article in The Lancet that looked into the relationship between carbohydrate quality and health. They carried out a series of systematic reviews and meta-analyses that evaluated around 135 million person-years of data from 185 prospective studies as well as 58 clinical trials with 4635 adults. They found that those with higher intakes of fibre had lower body weight, lower systolic blood pressure and lower total cholesterol. Those with higher fibre intakes also had a decreased incidence of coronary heart disease, stroke, type 2 diabetes and colorectal cancer, which may explain the 15-30% decrease in all-cause mortality between the groups with high and low fibre intake. Daily intake of fibre between 25g-30g seemed to confer the greatest risk reduction, although they note that “higher intakes of dietary fibre could confer even greater benefit“.

Low Carbohydrate Diets Are Bad For Health

Yesterday professor Banach, from the Medical University of Lodz in Poland, released the findings of his research at the European Society of Cardiology. The prospective study looked at the relationship between low carbohydrate diets, all-cause mortality and deaths specifically from coronary heart disease, stroke and cancer. The study group consisted of almost 25,000 adults from the US National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010. Over an average 6.4-year follow-up, compared to the group with the highest consumption of carbohydrates, the group with the lowest consumption had an increased risk of all-cause mortality (32%) and an increased risk of death from coronary heart disease (51%), stroke (50%) and cancer (35%). These results were backed up by the findings of a meta-analysis of several studies involving close to 450,000 people.

Professor Banach said: “Low carbohydrate diets might be useful in the short term to lose weight, lower blood pressure, and improve blood glucose control, but our study suggests that in the long-term they are linked with an increased risk of death from any cause, and deaths due to cardiovascular disease, cerebrovascular disease, and cancer. The reduced intake of fibre and fruits and increased intake of animal protein, cholesterol, and saturated fat with these diets may play a role. Differences in minerals, vitamins and phytochemicals might also be involved. Our study highlights an unfavourable association between low carbohydrate diets and total and cause-specific death, based on individual data and pooled results of previous studies. The findings suggest that low carbohydrate diets are unsafe and should not be recommended.“

Physical Activity and Health

A group of researchers led by Per Ladenvall (University of Gothenburg in Sweden) have looked into the relationship between physical capacity and health. They studied 800 middle-aged men over a period of 45 years. Physical fitness was measured by VO2 max. The results showed that low physical fitness is a greater risk of death than high blood pressure or cholesterol. It was second only to smoking as a risk of death.

Several studies have linked prolonged sitting with increased risk of mortality. A meta-analysis of data from over a million people was recently conducted by Ekeland et al. They wanted to find out if physical activity could attenuate, or even eliminate, the detrimental association of sitting time with mortality. They found that “high levels of moderate intensity physical activity (about 60–75 min/day) seem to eliminate the increased risk of death associated with high sitting time. However, this high activity level attenuates, but does not eliminate the increased risk associated with high TV-viewing time”.

Once again, the benefits of physical activity and physical fitness are clear. It’s up to us to make it a priority to move more, whether it’s through structured exercise or simply through the activities of daily living.

Longevity Uncovered

Would you like to live longer? Of course! I can remember as a child having what could initially appear as a morbid fascination for cemeteries. I used to drag my parents into each and every cemetery we walked or drove by…just so I could calculate how long people had lived! Perhaps my curiosity in longevity led to an interest (some may say obsession) in health.

 

Having just read “The Blue Zones” by Dan Buettner, I’d like to share some of his insights. Blue zones represent regions of our planet where people generally live significantly longer. For years, Buettner and his collaborators have searched the globe for those treasured blue zones in the hope of learning how to improve our health and increase our longevity.

 

So far, five blue zones have been identified: the mountainous regions of Sardinia, the island of Okinawa in Japan, Loma Linda in California, the Nicoyan peninsula in Costa Rica and the island of Ikaria in Greece. The first striking characteristic is that these regions are isolated by geography, culture or religion. This seems to be crucial because it means the people living in these regions have been able to continue living a traditional lifestyle until very recently. Most have grown up leading physically active lives and eating mainly plant-based diets (due to the cost of meat). Family and socialising is central to their lives. Although a lot have lived through hardships, they lead relatively stress-free lives primarily because they place little importance on money, material possessions, job status, etc.

 

Buettner has identified common factors that are associated with longevity and distilled them down to 9 lessons. He stresses that these practices are only associated to longevity but don’t necessarily increase it. As we know association isn’t the same as causation. The 9 lessons are:

1. Move naturally. Walk, cycle, garden, enrol in enjoyable classes
2. Eat until you’re 80% full. Don’t stuff yourself
3. Plant-based diet. Avoid meat and processed foods
4. Alcohol (in moderation)
5. Purpose. Have a reason to get out of bed in the morning
6. Downshift. Take time to relieve stress
7. Belong. Participate in spiritual community
8. Loved Ones First. Make family a priority
9. Right Tribe. Be surrounded by those who share Blue Zone values

 

He recommends introducing one or two of them at a time. It may be easier to start with the lessons we have a greater affinity for or simply those we find easiest to adopt. It’s not even necessary to try to follow all the steps. There you go…no rocket science or witchcraft required!

Positive Emotions Improve Health-Related Behaviours

Positive psychological states have been linked to better health and longevity. It’s believed to be partly due to the effect of positive emotions and moods on behaviour. Nancy Sin and her colleagues from the university of Penn State evaluated 5-year associations between positive affect and health behaviours in patients with coronary heart disease.

At baseline, they found that subjects with higher positive emotions and moods tended to have better health behaviours such as: physical activity, sleep quality, non-smoking and medication compliance. However, the baseline measurements of positive affect were not predictive of health behaviours at follow-up. Instead, it was increases in positive affect over the 5 years that were linked to improved physical activity, sleep quality and medication compliance.

The authors conclude that “efforts to sustain or enhance positive affect may be promising for promoting better health behaviours”. Although this may be easier said than done, positive psychology does offer methods and techniques to help achieve this aim.

The Miracle Cure

Scarlett McNally, a Consultant Orthopaedic surgeon, and her colleagues have spent 2 years analysing more than 200 separate pieces of research. The effect that regular exercise could have on our health is amazing. Exercise could:

• prevent type 2 diabetes
• reduce the risk of getting breast cancer by 25%
• decrease the risk of bowel cancer by 45%
• reduce the risk of having a stroke by 30%
• reduce the risk of developing dementia by 30%
• cut the risk of developing heart disease by over 40%
• as well as improvements to mental health

Exercise doesn’t have to be vigorous but it should be regular. Simply start by increasing your physical activity in whatever way you can: walk more, take the stairs, do some gardening, ride a bike…the possibilities are endless!

The 5 Habits of Highly Healthy People

Since 1979 Professor Peter Elwood and his team of researchers from Cardiff University School of Medicine have tracked the lifestyle habits of 2500 men aged 45-59 (at the start of the study). They found that men that followed 5 habits had 70% less chance of developing diabetes, 60% reduced incidents of heart attacks and strokes, 40% fewer cancers, and a reduction of 60% in cases of dementia. Incidentally, less than 1% of the study group followed all 5 habits! These 5 habits have the potential to reduce illness and chronic disease and so promote longevity…what are they?

The 5 habits of highly healthy people are:

• regular exercise
• no smoking
• a healthy bodyweight
• a healthy diet
• a low alcohol intake

Not rocket science by any means…and definitely within everyone’s grasp!

Relaxation For Health And Well-Being

The word ‘stress’ has become ubiquitous, but what exactly does it mean? It’s probably in the 1920s that it was first used in its present context. Walter Cannon used it to describe the process where external factors disturbed the body’s natural equilibrium. Around the same time, Hans Selye described stress as the non-specific response of the body to any demand placed upon it. Still confused?

Let’s put things a little more clearly. To ensure our survival we must either be in ‘protection mode’ or in ‘growth mode’. Protection mode ensures our short-term survival i.e. running away from or slaying a sabre-toothed tiger, moving out of the way of an oncoming car, etc. Growth mode ensures our long-term survival i.e. taking in nutrients by eating and digesting a meal, recharging our batteries by sleeping, wound-healing, having sex and reproducing, etc. Protection mode is more commonly known as ‘fight-or-flight’ and growth mode as ‘rest-and-digest’. They are like two sides of the same coin…it’s either one or the other…we’re either in ‘fight-or-flight’ or we’re in ‘rest-and-digest’. You may be more familiar with ‘fight-or-flight’ or the stress response as it’s also known.

The stress response kicks in as soon as we sense a threat. Things start off in the amygdala deep inside our brains. Other areas of the brain (hypothalamus, pituitary gland) also become involved as does the sympathetic nervous system. The adrenal glands then release adrenaline and cortisol. The aim is to quickly prepare the body for vigorous muscle activity by releasing fats and glucose into the blood stream, increasing the heart rate and breathing rate, dilating blood vessels in muscles, increasing blood pressure and increasing muscle tension. All this helps get us immediately primed for action without having to go through any mental preparation or physical warm-up! It sounds too good to be true and it’s helped us survive and thrive through time. Fortunately nowadays, we don’t often face the type of physical emergency the fight-or-flight system was designed for…but our brains still perceive lots of threats out there…traffic jams, time pressures, bad bosses, financial worries, difficult partners, noisy kids, not to mention 24/7 connectivity, contactability and accountability with the advent of new technology! All this ends up firing off our stress response in a completely different context than that for which it was designed. Rather than a sporadic short blast, it’s now more of a constant slow simmer…without the physical activity required to reset the system. Almost like preparing for a battle that never arrives…revving a car that never goes anywhere.

This ongoing low-level stress response has negative consequences. According to the Mayo Clinic, if left unchecked, “stress can contribute to health problems such as high blood pressure, heart disease, obesity and diabetes”. They cite the following common effects of stress:

What’s the solution? The key is to find a way of getting ourselves back into ‘rest-and-digest’ mode. In 1968 Herbert Benson, a cardiologist from Harvard Medical School, fortuitously stumbled across something whilst studying blood pressure. He had been approached by a group of transcendental meditators claiming they could lower their blood pressures through the use of their minds! Initially sceptical and reluctant to study them, he eventually succumbed and discovered what he called the ‘relaxation response’. Benson described the relaxation response as the opposite of the ‘fight-or-flight’ or stress response, it’s essentially the ‘rest-and-digest’ mode mentioned earlier. He characterised it by:

• Decreased metabolism, heart rate, blood pressure and rate of breathing
• A decrease or calming in brain activity
• An increase in attention and decision-making functions of the brain
• Changes in gene activity that are the opposite of those associated with stress

 

Research has found that the relaxation response can be effective in treating the following complaints:

Additionally, research shows that mind-body techniques can also be effective in treating the following:

In summary, any symptom or disease caused or exacerbated by stress can be helped by relaxation. Happily, there are lots of ways to evoke the relaxation response such as relaxation techniques (progressive relaxation, passive muscular relaxation, Mitchell method, breathing exercises, etc.), meditation, prayer, yoga, tai chi, exercise, cognitive behavioural therapy and hypnosis.

Hypnosis is a personal favourite of mine. It can combine the immediate relaxing effects of relaxation techniques with a change in thinking, mood and behaviour such as can be obtained using CBT. Better still, because it uses the power of the unconscious mind, these changes take place effortlessly…as if by magic!
