Brain Health

Did you know that in Canada, currently, there are 564,000 individuals living with dementia according to the Alzheimer Society of Canada. This number is expected to increase to 1.4 million people by 2031.
With so many different forms of dementia, with varying degrees of severity, it is no wonder that at times it is hard to diagnose, find treatment and more importantly find a cure!
Symptoms that may include memory loss, difficulty completing tasks, reduced reasoning, communication problems, mood changes, forgetful of family/friends, and loss of coordination.
Let’s face it, from time to time we all may struggle with a bit of mood changes, difficulty communicating or forgetfulness which we cause us to laugh at ourselves or dismiss, especially if we are over tired or under a lot of stress.
The signs that present in those who suffer from depression; sadness, frustration, anxiety and concentration to name a few, have similarities with symptoms of individuals with dementia. No matter how such symptoms appear, they all impact our overall brain health.
The good news is, we can boost brain function by introducing EVOO into our diets.
Of course we insist that it be high phenolic EVOO!
EVOO actually slows down the aging process and helps to keep our brains young and healthy.

Breast Health

It is Breast Cancer Awareness month, as we’re sure many of your know. We prefer instead to acknowledge this as “Breast Health Awareness” month. It is a much better approach and serves us more lovingly when we think in terms of being healthy! Our mind is powerful with its thoughts and feelings. Feed it well!
Published November 2015, in Harvard Healthy Publishing is the article “High olive oil consumption linked to lower breast cancer risk”.
Just one more reason to incorporate a daily dose of high phenolic EVOO into your daily diet.

Plant-Based Diet


Adopting to a plant-based diet is one the most important steps you can take to help prevent chronic diseases, boost your immune system, increase your energy and add vitality into your life.

 

The choices you make today to eat nutritious plant foods not only increases your longevity, but helps the environment as well.

There is much science available that shows how making good choices today to eat more nutritious food will help increase your longevity and help the environment too.

Hippocrates had said, “let food be thy medicine” for good reason.

Now through we have learned a great deal about how the ancient wisdoms, when met with modern science contribute to our daily health and wellbeing.

There is no doubt that by eating a healthful diet we have the ability to promote the prevention and reversal of many chronic diseases such as diabetes, obesity and even many types of cancers.

There are so many reasons to adopt this way of eating and it is easier than you may think.

Of course, we recommend that you start with a daily consumption of 1-2 tbsps of high phenolic extra virgin olive oil first thing each morning on an empty stomach.  Your body needs a healthy amount of fatty acids to protect you brain, heart, bones and joints.  Not only that, but you will benefit from better sleep, healthier hair and smoother skin.  Think of it as your daily shot of “anti-aging”!

Cooking with Olive Oil

Yes, you can cook with olive oil! In fact, it is the healthiest oil to cook with.

Cooking with olive oil has raised concerns due to a low smoke point, however the focus should be on the oxidative stability and level of refinement.

To learn more about busting the myths of not cooking with EVOO, have a read of this article from the National Olive Oil Association, Cooking Oil and Oxidative Stability.

 

Rancid Fats & Oils

This article The Health Implications of Rancid Fats and Oils, written by Jacqui Plozza, is posted at The Olive Wellness Institute.

 The Health Implications of Rancid Fats and Oils

All food will deteriorate over time. For example, fresh fruits and vegetables can ferment, and fats and oils will go rancid.

There are concerns that consuming rancid fats and oils is damaging to health. Whilst more research is needed to establish impact of long-term consumption of rancid fats and oils, this article discusses some of the current evidence, factors that contribute to an oil becoming rancid and common sources of rancid oils.

What is rancidity?

Rancidity is the term used to describe the breakdown and deterioration of fats and oils. It involves various chemical reactions and results in unpleasant odours and flavours.1  The major mechanism through which a fat or oil becomes rancid is via “oxidative rancidity”. Oxidative rancidity arises from the decomposition of peroxides. In this case, the oil breaks down due to exposure to oxygen and forms decomposition products such as aldehydes, ketones and hydrocarbons.1 These by-products contribute to the unpleasant flavours and aromas associated with rancid fats and oils.

An oil is more prone to oxidation and rancidity if it is:

  • High in polyunsaturated fat – Polyunsaturated fat is highly susceptible to oxidation due to double bonds, as this is where oxidative damage occurs.2, 3
  • Exposed to prolonged heat, light or oxygen.3 Inadequate storage conditions for an oil can speed up oxidation through increased exposure to these factors.3
  • Naturally low in antioxidants – antioxidants protect an oil from oxidising and are often added in limited permissible amounts to refined seed oils that are high in polyunsaturated fat to protect the oil from oxidising.4
  • Refined or heavily processed – oil-processing methods affect an oils oxidative stability through mechanisms such as removing antioxidants.3

Where are rancid fats and oils found?

Rancid fats and oils can be found in a variety of sources.

Cooking oils

Food sources of rancid fats and oils include cooking oils that are higher in polyunsaturated fat as they are more susceptible to oxidative damage due to multiple double bonds.2, 3 Oils high in polyunsaturated fat include sunflower oil, corn oil, flaxseed oil and soybean oil. For a comparison of the fatty acid profile of common cooking oils, click here.

Herbal supplements and essential oils

In terms of supplement products, herbal supplements and essential oils often contain “carrier oils”.5 A carrier oil is the vehicle for the product, intended to preserve the potency and delivery of the active compounds within a substance.6 For example, CBD oil is currently a popular supplement in the health and wellness world. It is extracted from the cannabis plant and then diluted with a carrier oil like coconut oil, hemp seed oil or extra virgin olive oil. Whilst coconut oil and extra virgin olive oil contain very little polyunsaturated fat, hemp seed oil is predominantly polyunsaturated fat, and therefore more prone to oxidation.7 Additionally, extra virgin olive oil is high in natural antioxidants, which also protect oil from oxidation and rancidification.

 

Fish oil supplements

Fish oil capsules are the most common non-vitamin, nonmineral supplement in the United States, taken by 10% of adults.8 Fish oil is rich in omega-3, a polyunsaturated fat, and therefore readily oxidises. Multiple studies in countries such as Australia, the US, New Zealand and Africa show that many fish oil supplements readily available on supermarket shelves are oxidised.9-13

A 2018 Australian study showed that 38% of 26 fish oil supplements tested exceeded the limit for primary oxidation, as measured by Peroxide Value (PV), a key measure of an oils rancidity.9 Supplements tested were bought off shelf, as consumers would purchase them, and mostly had at least one year until their expiry date.

A comprehensive 2015 survey of fish oil supplements on the New Zealand market showed that 83% of 32 products tested exceeded the recommended level of PV’s, 33% by more than twofold.13 A 2015 North American study looked at 171 fish oil supplement products and found that 50% exceeded the voluntary recommended levels for markers of oxidation.10

 

 

What are the health implications of consuming rancid fats and oils?

Consuming rancid fats and oils may reduce the nutritive value of the food by destroying vitamins such as Vitamin A and E.14, 15 There is also evidence to show that decomposition products produced by oxidised oil may be detrimental to health and have been linked to the development of neurodegenerative conditions such as Alzheimer’s and Parkinson’s Disease.16-19

In animal studies, exposure to oxidised oils and fats has been shown to cause harm including growth retardation, organ toxicity, accelerated atherosclerosis, reduced immunity parameters, high newborn mortality and increased maternal insulin resistance.20-23

Evidence into the impact of consuming rancid oils in humans is mixed. A 2016 Randomised Control Trial (RCT) in healthy subjects suggested that short-term consumption of oxidised fish oil may not have a negative impact at the molecular level. It found no difference in the transcriptome between those randomized to high quality or oxidised fish oil in the short term.24 The oxidised fish oil had a PV value of 18 meq/kg and participants were prescribed 8g per day for seven weeks.

On the flip side, more oxidised fish oils may be less effective in reducing chronic disease risk factors. A 2013 RCT found that consuming less oxidised fish oil reduced circulating cholesterol and triglycerides more so than more oxidised fish oil.25

The impact of long-term exposure to rancid oils (i.e. consuming for months or years) has not been investigated rigorously.25 However, the current body of evidence suggests long term exposure to lipid oxidation products in doses seen in fish oil supplements, for example, are likely to have adverse effects on inflammation, oxidative stress and lipid metabolism.26

A longer running 2007 North African study looked at food items that were associated with Nasopharangeal Carcinoma (NCP) and found that rancid butter and rancid sheep fat were associated with significantly increased risk of NPC.27 North Africa is one of the major NPC endemic regions. The large-scale case-control study looked at over 600 cases and 600 controls over a period of four years.

 

 

Conclusion

Although the impact of consuming rancid fats and oils in humans is yet to be fully elucidated,  animal studies indicate that consuming rancid oils is detrimental to health. Therefore, people should avoid consuming rancid oils where they can.

Ways to achieve this include:

  • Select fats and oils from a reputable trusted source.
  • Favour an oil that is lower in polyunsaturated fat such as extra virgin olive oil or coconut oil, as polyunsaturated fat oxidises more readily.
  • Choose an oil that is high in natural antioxidants, such as extra virgin olive oil.
  • Select a packaging size that allows full utilization of the oil within 4-6 weeks depending on family size and consumption patterns.
  • Store cooking oils and oil supplements in a cool dry place and use within the best before date.
  • In the case of fish oil supplements, look to the studies that review oxidation of specific brands in various countries, or look to meet omega recommendations through food sources where possible.
