Hypertension – Dietary Factors

Following on from my introduction to hypertension and lifestyle factors, I want to explore the link between diet and hypertension in this blog.

Optimise your Gut Flora

Compared to a placebo, people with high blood pressure who consumed probiotics lowered systolic blood pressure (the top number) by 3.56 mm Hg and diastolic blood pressure (the bottom number) by 2.38 mm Hg1.  Including taking probiotics, its is helpful to avoid sugar and processed foods.  I should mention that naturally fermented foods in your diet, may contain about 100 times the amount of bacteria than found in a bottle of high potency probiotics. But I appreciate form a practical point of view, buying probiotics is much easier!

Eat a Healthy Diet

I appreciate this is very common advice.  In 1998 in the journal of Diabetes reported that nearly two-thirds of the test subjects who were insulin resistant also high high blood pressure.  Insulin resistance is directly attributed to a high sugar, high carbohydrate diet especially if combined with inadequate exercise.

Avoiding processed foods (due to their being high in sugar/fructose, grains, trans fat, and other damaged fats) is my number one recommendation if you have high blood pressure2. Instead, make whole, ideally organic, foods the focus of your diet. As you reduce processed foods, and other sources of non-vegetable carbs, from your diet, you’ll want to replace them with healthy fat.

  • A Guide to Sciatica

    One of the most common questions I get asked, by my clients is "is my back pain sciatica?".  So I would like take some time to explain what sciatica or piriformis syndrome is. Sciatica is the irritation of inflammation of the sciatic nerve, which runs from L3 down through your legs and feet to your toes, so its the longest (and widest) nerve in the human body.  The reason sciatica is called piriformis syndrome is that the piriformis muscle (which is in your bum) can compress the sciatic nerve.  Because in most people approximately  87% the sciatic nerve passes below the piriformis muscle, in approximately 13% people the sciatic nerve passes in part or entirely though the piriformis muscle.  So tightness in the piriformis muscle is a major cause of sciatica and this tightness can be exasperated by prolonged sitting.  Other notable causes are trauma to your lower back or your pelvis, a history of herniated disc in your lower back and some systemic diseases e.g. diabetes. So how can you tell if you have sciatica or lower back pain?  Sciatic is characterised by the presence of one or more of the following symptoms:

    • Constant pain in one side of the buttock or back of one leg.
    • Sharp or burning pain or tingling radiating down the back of your thigh.
    • Pain is worse when sitting for long periods of time.
    • Pain may be aggravated by sneezing, stooping or straining.
    • You feel that you want to slouch away from the effected side.
    • Possible pins and needles or parasthesia (numbness) down leg.
    Sciatic pain can begin abruptly or can come on gradually and may vary from infrequent and irritating to constant and incapacitating.  While symptoms can be very painful, it is rare that permanent sciatic nerve damage (tissue damage) will result. The vast majority of people who experience sciatica get better within a few weeks or months and find pain relief with non-surgical sciatica treatment including massage. For others, however, sciatica pain from a pinched nerve can be severe and debilitating. There are a few symptoms that may require immediate medical, and possibly surgical, intervention, such as progressive neurological symptoms (e.g. leg weakness) and/or bowel or bladder dysfunction.

  • So how does massage help “tired” muscles?

    Many clients come to our clinics a few days after vigorous work outs or competing in sporting competition because their legs feel tried or heavy.  These clients often book a sports massage, but is their any scientific evidence to explain what is happening in the body during the treatment? Massage dilates superficial blood vessels and increases the rate of blood flow.  In addition if a deeper pressure is used like in sports or deep tissue massage on a healthy adult it improves the venous return.  Both of these changes to the blood flow represent a potent means to accelerate healing.  For example, it suggests that massage should improve the performance of fatigued muscles.  In addition, Goats asserts that massaged muscle fibres display less spasm, an increased force of contraction and enhanced endurance compared with muscles simply rested.  Which suggests that massage will assist in the improvement of sporting performance where it has been compromised.
