This week’s blog is short one, but a powerful one.

It comes out of my recent experiences at the Pharmacy WA Forum in Perth chatting to some of the naturopaths and integrative pharmacists. They got very excited about the Daily Gut Health Boosts on our stand. They recognized the value of the partially hydrolysed guar gum (PHGG) in our Boosts not just to improve gut health, but other conditions too.

We include PHGG in our range primarily because of its gut health benefits. It not only helps with occasional constipation, but it also helps with diarrhoea, returning poop content to a normal healthy state without the bloating, cramping and gas production caused by some other types of fibre. It’s also a good prebiotic and increases the number of beneficial bacteria in the gut microbiome. It’s fermented into highly beneficial compounds called short-chain fatty acids (SCFAs). Short-chain fatty acids fuel the cells of the digestive tract, keeping the gut healthy. If you want to read more about these gut health benefit check out our blog here.

But if you want to find out about additional benefits of PHGG, read on.

Cholesterol lowering effects of PHGG

High levels of cholesterol and triglycerides in the blood are risk factors for heart disease. Given, coronary heart disease is the number one cause of death for men in Australia and number 2 after dementia for Australian women, we all need to be aware of our cholesterol numbers (levels of bad LDL cholesterol and good HDL cholesterol) and working to improve them..

The soluble fibre found in oats and psyllium has long drawn attention for its ability to change lipid levels in the blood and reduce the risk of coronary heart disease.

Similarly, Kondo and colleagues conducted a study on blood lipid levels in healthy young males, again with slightly elevated cholesterol levels. Consuming 6 g of PHGG mixed in a yoghurt drink along with a high-fat and cholesterol-rich challenge food (containing cream and egg yolk) led to a reduced rise in serum triglycerides and serum remnant like particle cholesterol (RLP-C) compared to when they consumed the same challenge food without the PHGG.  This is good news because RLP-C is highly predictive of heart attacks, more so than any other lipid particle including LDL cholesterol. A side-study showed that just 3g of PHGG has almost as good a suppressive effect on post-meal triglycerides and RLP-C levels.

The researchers suggested that the branched structure of PHGG with galactose side chains suppress fat absorption in the gut.

Key points

If you have high levels of harmful cholesterol, adding a shot of Daily Gut Health Boost (with 5 g of PHGG per serve) to your routine isn’t a quick fix, but it can be helpful as part of a multi-faceted approach combining lifestyle, medication and dietary changes to improve your health.

When my father was first prescribed statins, I remember him opting for fruit for dessert and wisely declaring that “there’s no point me taking statins and then eating cream cakes”.  It’s the right attitude - his ticker is still going strong at 80.

So what changes are useful to build a healthy cholesterol profile (low LDL and high HDL) and lower triglycerides? Here’s our top tips:
