Musculoskeletal System Disease
o Bone maintenance is under hormonal control, and
nutrients play a major role in this
• Parathyroid Hormone
• 1,25-Dihydroxyvitamin D3
• Negative Feedback Control of Calcium and
Phosphate Balance
• Calcitonin

Osteoarthritis
Synovial joints present with cartilage loss and significant
inflammation to articular and peri-articular structures.
o Morning stiffness (better for movement)
o Grinding of joints (crepitus)
o Loss of mobility, range of movement
o Pain after prolonged activity
o Pain relieved by rest
o Muscle contractures and spasms
o In advanced OA, redness, heat,
swelling, enlargement of joint,
bone spur formation. (Rona, 2000)

Predisposing factors;
o Obesity
o Heredity
o Gender
o Biochemical abnormalities
o Previous trauma or inflammation

OsteoarthritisTreatment Aims
o Support pain management and anti-inflammatory action
o Maintaining adequate microcirculation to the joints
o Minimize load bearing exacerbation (obesity) while still
encouraging / sustaining activity of the joints while
supporting appropriate muscular articulation and
preventing further joint injuries
o Nutritional support for proteoglycan synthesis and
cartilage reconstruction
o Remineralisation of the calcified cartilage / bone junction
o Adjust the diet to have a less acidic load

Gout
© Endeavour College of Natural Health endeavour.edu.au 18
Gout
o Gout is an inflammatory arthritis associated with
hyperuricaemia (raised urate levels in the blood).
o Increased action of xanthine oxidase. This increases the
clearance of purines, however, a failure of the kidneys to
effectively clear the generated metabolite results in the
compound continuing to circulate throughout the body.
o This leads to deposition in joints
(Kumar & Clark 2009; Tortora & Derrickson, 2009)
© Endeavour College of Natural Health endeavour.edu.au 19
Gout
Investigations
o joint fluid microscopy
o serum uric acid levels
o serum urea and creatinine
clearance to monitor renal
function

Gout
Therapeutic Actions
Vitamin C
Huang et al. (2005) found that the incidences of
hyperuricaemia were higher in males and those that
suffered chronic illness.
The study found that ;
“Supplementation with 500mg/d of vitamin C for 2 months
reduces serum uric acid, suggesting that vitamin C might
be beneficial in the prevention and management of gout
and other urate-related diseases”. (pp. 1845)
© Endeavour College of Natural Health endeavour.edu.au 22
Gout
Therapeutic Actions
Anthocyanidins & Pro-anthocyanidins
o Consuming 200gms of fresh or canned cherries per day has been shown to be very effective in lowering uric acid levels.
o Cherries, hawthorn berries, blueberries and other dark red-blue berries are rich sources of anthocyanidins and pro-anthocyanidins which supports collagen structures.
(Haslett et al. 2002; Jacob, 2003)
© Endeavour College of Natural Health endeavour.edu.au 23
Gout
Nutritional Considerations
Alcohol
o Alcohol increases uric acid production by accelerating
purine nucleotide degradation and reduces uric acid
excretion by increasing lactate production which impairs
kidney function
(Lyu et al. 2003; Pizzorno & Murray 2006)
o It has been found that groups with gout have double the
alcohol intake of healthy controls
(Sharpe, 1984 too old!)
© Endeavour College of Natural Health endeavour.edu.au 24
Gout
Nutritional Considerations
Refined sugars
o Hyon et al. (2008) found in a longitudinal study of males
with no history of gout that consumption of sugar
sweetened soft drink and fructose rich fruit drinks
increased the incidence of gout.
o The increased presentation was four times that of the
normal distribution of disease incidence.
© Endeavour College of Natural Health endeavour.edu.au 25
Gout
Nutritional Considerations
Folate, Vitamin C, Fibre and Obesity
o Lyu et al (2003) found that “food sources rich in dietary
fibre, folate, and vitamin C, such as fruit and vegetables,
protect against gout. Waist-to-height ratio, which
indicates central obesity, has a significant linear effect on
gout occurrence, independent of body mass index.” (pp.
699)
© Endeavour College of Natural Health endeavour.edu.au 26
Gout
Nutritional Treatment
o Eat low purine foods (purine rich foods include yeast,
shellfish, organ meats & offal) while eliminating refined
sugar in drinks, food & alcohol
o Consumption of fibre, folate, vitamin C rich foods &
coffee was associated with a lower risk & lowered rate of
flare-ups.
o High essential fatty acid intakes & drinking a minimum of
2 litres /day of filtered water is beneficial
o Reduce an unhealthy waist-to-height independent of
body mass index
(Lyu et al. 2003; Pizzorno & Murray, 2006; Jasvinder et al.

Gout
Drug Action Side Effects Interactions
Xanthine
Oxidase
Inhibitor:
Allopurinol
Reduces the
synthesis of uric
acid (inhibits
xanthine oxidase).
This increases
xanthine’s use in
nucleic acid
synthesis which in
turn inhibits purine
synthesis. Useful for
urate deposits in the
joints (Gout) & urate
kidney stone
formation
Skin irritation
(itch, rash,
dermatitis,
alopecia),
abdominal
irritation
(diarrhoea,
vomiting),
Liver toxicity,
kidney
damage
Iron: Concurrent usage can lead
to excessive storage of iron in
the liver
Tryptophan: Allopurinol
decreases tryptophan
breakdown. Concurrent usage
can aid depression and help pain
management.
Vitamin D: Allopurinol has been
found to elevate serum vitamin D
levels. Monitor for vitamin D
toxicity signs with concurrent
administration
(Stargrove et al. 2008; Bryant & Knights, 2011)

side effects.
Niacin: Doses of vitamin B3
(above 50mg/day) have been
found to reduce uric acid
excretion.
Ascorbic Acid: combined use
has been found to increase uric
acid excretion. Higher doses of
ascorbic acid have been found
to cause gout attacks.

Osteoporosis
© Endeavour College of Natural Health endeavour.edu.au 32
Osteoporosis
o A generalised, progressive loss of bone density, causing
skeletal weakness, although the ratio of mineral to
organic elements is unchanged.
o Bones become porous, brittle and less dense as a result
of a loss of bone mass due to osteoclast dominance
(Kumar & Clark 2009; Tortora & Derrickson 2009; Vardaxis, 2010)
© Endeavour College of Natural Health endeavour.edu.au 33
Osteoporosis
o Bone mass peaks in the middle of the 20’s and plateaus
for about 10 years.
o Turnover of bone is constant, with bone formation
approximately equalling bone resorption.
o Menopause and andropause causes accelerated bone
loss (may be increased tenfold at the rate of 3 to
5%/year)
o The movement of calcium and phosphorous in and out of
bone is under the control of Parathyroid hormone (PTH),
1,25 Vitamin D3 (calcitriol), Calcitonin
o Gonadal hormones also play a major regulatory role.
(Haslett et al. 2002; Vardaxis, 2010)
© Endeavour College of Natural Health endeavour.edu.au 34
Osteoporosis
Bone Loss Associated factors:
o Cushing's syndrome
o Hyper parathyroid
o Anorexia nervosa
o High intake of alcohol
o Smoking
o Drug usage (corticosteroids, progesterone,
anticonvulsants, thyroid hormones, methotrexate,
cyclosporin, non-thiazide diuretics, aluminum antacids,
anti-coagulants and high dose vitamin A and vitamin D)
(Vardaxis, 2010)
© Endeavour College of Natural Health endeavour.edu.au 35
Osteoporosis
Symptoms:
o Usually asymptomatic until severe backache
o Common in postmenopausal women
o Fractures to hips and vertebra
o Decrease in height
o Demineralization of the spine and pelvis
(Haslett et al. 2002; Pizzorno & Murray 2006)
© Endeavour College of Natural Health endeavour.edu.au 36
Osteoporosis
Therapeutic Actions
Insoluble Fibre
o Robefroid (2000) found that “…a high concentration of
short-chain carboxylic acids resulting from the colonic
fermentation of the non digestible carbohydrates
facilitates the colonic absorption of minerals, particularly
Ca2+ and Mg2+.”
o Insoluble fibre fractions such as inulin can increase in
water retention in the bowel allowing minerals to dissolve
and increase in concentration. This encourages passive
diffusion and subsequent increased absorption.
© Endeavour College of Natural Health endeavour.edu.au 37
Osteoporosis
Therapeutic Actions
Vitamin D, Calcium and Garlic oil
o Rasheed et al. (2009) found that animal trials
supplemented with “…vitamin D , calcium and oil extract
of garlic could effectively restore the reduced calcium
level, correct the high rate of bone turnover, elevate the
reduced serum estradiol level and improve both BMC
and BMD after ovariectomy. This effect was better in the
group co-administered with the three components”.
© Endeavour College of Natural Health endeavour.edu.au 38
Osteoporosis
Therapeutic Actions
Calcium and BMI
o Varenna et al. (2007) found that “…the negative effect of
a low dietary calcium intake on BMD values in the first
years after menopause can be attenuated by a greater
BMI found in women with a low calcium intake.”
© Endeavour College of Natural Health endeavour.edu.au 39
Osteoporosis
Therapeutic Actions
Soy Isoflavones
o Scheiber et al (2001) conducted a study to determine the
effects of dietary inclusion of soy foods on clinical
markers for cardiovascular disease (CVD) and
osteoporosis in normal postmenopausal women.
o The conclusion was that “dietary soy foods containing
60mg/day of isoflavones results in significant increases
in serum levels of phytoestrogens and a subsequent
reduction in clinical risk factors for CVD and
osteoporosis.”
© Endeavour College of Natural Health endeavour.edu.au 40
OsteoporosisSoy
o Beneficial effects of soy on bone density have been reported in
epidemiological studies.
o One study gave 200 women 66mg of isofalnones or a soy protein
supplement/day (equivalent to an Asian diet intake) for six months.
o The researchers investigated changes in the women's bone activity by
measuring certain proteins (βCTX and P1NP) in their blood (responsible
for bone breakdown) & found that the women on the soy diet with
isoflavones had significantly lower levels of βCTX than the women on
soy alone, suggesting that their rate of bone loss & risk of developing
osteoporosis was reduced.
o Women taking soy protein with isoflavones were also found to have
decreased risk of cardiovascular disease than those taking soy alone.
o Conclusion - soy protein and isoflavones are an effective option for
improving bone health in women during early menopause. The actions of
soy appear to mimic that of conventional osteoporosis drugs
(Society for endocrinology 2015)

Osteoporosis
Nutritional Treatment
o Eliminate soft drinks (high in phosphates)
o Increase dietary and supplementary calcium intake
o Consumption of leafy green vegetables (vitamin K ,
boron and calcium)
o Increase intake of foods high in Vitamin D and ensure
exposure to sunlight
o Reduce fat intake, eliminate refined sugar, avoid
smoking & drink alcohol in moderation
o Participate in weight bearing exercise daily & maintain
ideal body weight
(Kohlmeier, 2003; Pizzorno & Murray 2006; Schlenker & Long 2007; Straub 2007; Rasheed
et al. 2009)
© Endeavour College of Natural Health endeavour.edu.au 42
Osteoporosis
Preventative Strategies include:
o Maximizing peak bone mass (peak bone mass achieved
at age 30 years)
o Avoidance or modification of lifestyle and environmental
factors that cause bone loss
o Use of treatments such as oestrogens to prevent
postmenopausal bone loss
o Maintenance of postural stability and prevention of falls
(Haslett et al. 2002; Kumar & Clark 2009)
© Endeavour College of Natural Health endeavour.edu.au 43
Osteoporosis
Treatment Aims
o In patients with established osteoporosis, the aim of all
treatment strategies (nutritional, dietary and
pharmaceutical) is very similar. These include;
o Alleviate the patient's symptoms (e.g. pain) if applicable
o Reduce the risk of fracture
o Improve bone mass
o Treat, any underlying or contributing causes such as
thyroid dysfunction, diabetes, achlorhydria, drug
therapies e.g. corticosteroids
(Haslett et al. 2002; Kumar & Clark 2009)
