Food marketing to kids?!?

UPFHave you ever perused the food options on the shelves of the supermarket looking for the healthiest option, and then read the ingredients only to find it was loaded with sugar…or something that sounds like sugar but you just can’t be sure? A recent Australian study (Pulker et al., 2018) sought to understand the impact of nutrition marketing and health claims found on the packaging of ultra-processed foods (UPF). An UPF is an industrially processed food, which may include colours, flavours, sweeteners and processing aids, or undergoes processing for which there is no domestic equivalent i.e. we can’t recreate these foods in our own kitchen. They are also described as hyper-palatable and are commonly marketed at children. Examples include breakfast cereals, snacks, confectionary items and breakfast meal replacements.

 

To carry out the assessment the researchers looked at the packaging information of UPF from 5 different manufacturers. The ingredient lists were examined for the addition of sugar as well as nutrition and health related claims, and food marketing.

The results were alarming. Ninety-five percent (95%) of UPF contained added sugar. There were 34 different terms used to describe sugar (I can’t even come up with half that amount). Just over half of UPF were moderate health star rated or had nutrition claims…yes these were the same foods that had added sugar. Almost all used food marketing, with half of those reviewed using marketing techniques aimed at children. So despite many foods containing sugar and being less than health options they are being marketed as nutritional.

The researchers were concerned about the inappropriate or inaccurate statements (in some cases) particularly those aimed at children. They recommended that surveillance of UPF be increased with the aim of reducing deceptive marketing practices. Additional recommendations include clear identification of sugar, correct identification of nutritional quality (or lack of quality), and a raft of other suggestions to increase clarity around food choices with relation to UPF.

From my perspective I hope these changes come about. In the meantime when shopping in the middle aisles (instead of around the edges of the supermarkets where the fresh food is located), aim to choose minimally processed foods or those with less ingredients e.g. muesli or rolled oats instead of cereals that contain added sugar. Another approach I take is to choose healthy daily basics such as rolled oats for breakfast and then when I want to indulge in a sweet treat (chocolate peanut butter icecream anyone?), I really go for it but the choice is mine rather than being hidden under layers of marketing guff.

Throwing the baby spinach out with the bath water

Recently I went into a well known supermarket looking for some leafy greens to go with the dinner I was cooking. I scanned the shelves and all I could see was packets of baby spinach, rocket or mixed greens, neither on their own, both mixed with baby spinach. I felt like I was in a monoculture world of greens and wanted to run screaming from the veggie aisle (not really, it was more of a sigh and start to think of alternative dinner plans). Dramatics aside, I did on the spot decide to boycott baby spinach for life…well for a little while anyway. I probably need to admit at this point that I am not a fan of baby spinach, I think it is overrated, over consumed and I would love to see more alternatives. While this opinion goes against the advice found in the popular media, which is ‘eat spinach, its a super green’, it isn’t isn’t an uninformed opinion so I have outlined my reasons for boycotting baby spinach below:

1. We are missing out on variety, which has an impact on the health of our microbiome. Not just through the over consumption of baby spinach, but generally reducing our food choices down to a few varieties that are available in the supermarket. I do think greens are an important part of our nutritional intake so consuming them regularly is ideal but mixing it up is key. Add some good old iceberg to your smoothie, celery, zucchini, rocket or even mixed leaves with baby spinach (see a more extensive list of alternatives at the end of the article). This will give you a wider intake of plant nutrients and an interesting start to the day!leafy-vegetables

2. It is high in oxalates or oxalic acid. Oxalic acid is a naturally occuring molecule which if eating in too large quantities can bind up minerals such as calcium and magnesium from other foods eaten forming oxalates and render the minerals inabsorpbable. In excess oxalates are also linked to kidney stones and inflammation in various body systems. This isn’t necessarily an issue if you have a healthy microbiome but a quick look at the avalanche of research about the health of our microbiome as a population and I think this is an issue we all have to consider. So how do we feed the health of our gut bugs? The key is, yes you guessed it, variety. Of course oxalates aren’t a big issue for most of us if we only consume them occasionally or as part of a varied diet but if your work lunch routinely consists of baby spinach, then it may become an issue, particularly if coupled with digestive health issues.

3. Baby spinach can cause the body to release histamines, a chemical produced by the body that in excess or those sensitive to histamine is linked to headaches, allergic responses, itchiness and rashes. I had one client who was a FIFO worker in a remote mine. This client made every attempt to be healthy in a location with limited supply of fresh fruit and vegetables and so avoided the canteen and instead made his own lunches. Every day for lunch at the mine he ate a spinach and tuna salad. Over a couple of months he started to develop a hive like rash all over his body, which cleared up when he came home and ate a varied, but in his words ‘less healthy diet’. We worked out quickly that the spinach and canned tuna were the culprits, encouraging the release of histamine and leading to the full body rash. A few simple changes in diet including cutting out the spinach and canned tuna and increasing variety saw his rash clear up.

4. Finally and I have to admit it I don’t like the flavour! I know I am already biased however I would love to see more variety next time I go to the supermarket and in the meantime I am fighting the chooks for my garden greens, bug free and delicious but slightly pecked!

So the key take home I would love you to take from this diatribe against spinach is to please consider vegetable and greens variety. Apart from the nutritional value, it will make for some interesting smoothies and salads and hopefully your palate will agree.

P.S. some alternative greens – all lettuce varieties – cos, iceberg, Romaine, butterhead, oakleaf, loose leaf lettuce, field lettuce, Asian greens, rocket, kale, chard, beet green, broccoli microgreens, mustard greens, endive, curley endive, chicory, radiccio (yes it’s red/purple but still), Japanese greens (found in lettuce mixes), escarole, cress, rosette bok choy, broccoli rabe, watercress, dandelion.

Is​ ​modern​ ​life responsible for skin conditions?

The skin is a protective barrier between the outside world and our internal processes. Living on the skin is a whole world of microbes otherwise known as the skin microbiome. This bacterial world plays a key role in maintaining skin health and those that inhabit our skin surface have many beneficial roles, both topically and more internally. Significantly the impact of dysbiotic, out of balance bacteria on the skin isn’t just felt locally either. Skin dysbiosis has been associated with local and systemic immune dysregulation and allergic conditions such as eczema, food allergy, psoriasis, rosacea, acne and skin ageing.

Healthy skin microbes have many beneficial roles:

  • Inhibits pathogen overgrowth e.g. staph, strep or p. acnes.
  • Enhances immune activity
  • Maintains healthy skin cell development and integrity
  • Modulates local skin stress responses including cortisol production
  • Regulates inflammation
  • Supports the skins innate antioxidant system, which helps protect against the impact of environmental toxins and allergens.

Similarly to the gut, the microbiome of the skin is greatly influenced by the environment and behaviour. Recent research suggests that modern life practices can disrupt of the delicate microbiome balance, altering barrier function and immunity and driving the overgrowth of detrimental bacteria. The combination of such factors helps in turn to drive the development of skin disorders.

 

So what are the key factors that disrupt our normal skin microbiota?

  • In infants, early bathing and the use of soaps, detergents and body washes can disrupt normal skin microbe colonisation and predispose infants to skin disorders.
  • The use of anti-bacterial body care products including hand washes can reduce skin barrier protection potentially allowing toxins and pathogens to pass through the skin and into the body. Such products are commonly used in healthcare for necessary hygiene but also more recently they have been widely promoted in schools e.g. anti-microbial hand washes.
  • Overuse of antibiotics can change the balance of skin bacteria.
  • Reduced exposure to nature impacts on the skin microbiome. Both the soil and plant materials are a source of bacteria. Those living in urban environments have less exposure to and contact with nature. Those living in close contact with nature have less skin disorders. (N.B. the impact of nature on stress responses may also impact on this relationship).

Time spent in nature is always well spent!

 

Based on this review, what then can we do to support our skin microbiome?

  • Spend more time in nature or green spaces in urban environments e.g. visit a national park or reserve, build or create a garden, transform vacant lots in your local area or contact your local council about natural streetscapes or kerbside gardens.
  • Grow indoor plants. They help with air quality as well as ‘bringing the outside in’.
  • Reduce the use of anti-microbial body and hand washes. Use regular soap instead.
  • Clean effectively but avoid anti-microbial sprays or cleansers in the home.
  • Avoid excess or early bathing with soaps or detergents in young infants. In very young infants a wet flannel wash or bath once a week is often enough. No soap is needed.
  • Avoid anti-microbial nappy wipes.
  • Avoid over-washing as an adult. Use soap where necessary on the body (armpits, groin, feet as necessary) but don’t use it on body parts that just don’t need it.

A new culprit in Type 2 Diabetes

Fat rather than sugar may be the most significant culprit in the development of diabetic neuropathy in Type 2 diabetics. Diabetic neuropathy is the most common complication of diabetes. It can occur anywhere but commonly in legs and feet leading to symptoms such as numbness, loss of sensation and pain. The accepted understanding of peripheral neuropathy in both Type 1 (T1D) and Type 2 diabetics (T2D) is that chronically high blood sugar levels cause it, which results in damage to nerves.

In a study of TID and T2D, magnetic resonance images (MRI) were used to see if there were different associations between neuropathic symptoms and metabolic indices including blood sugar control and lipid metabolism. What emerged is that there are differences in the type of nerve damage between T1D and T2D and further that the damage is likely to be caused by different metabolic factors. In TID the association between loss of nerve conduction and poor blood sugar control was strongly confirmed. However in T2D the predominant nerve lesions were associated with changes in lipid metabolism including elevated serum triglycerides and reduced HDL (healthy cholesterol) rather than poor blood sugar control. It is important to note that in T2D poor blood sugar control and unhealthy lipid metabolism occur hand in hand, which means that improving glycaemia control is still central to effective management of T2D overall. However, it now seems that focussing on healthy lipid metabolism may also become a central treatment focus in T2D with the aim of helping to prevent the progression of diabetic neuropathy.

While this research is still in the investigative stages there is great benefit from eating a diet that promotes healthy cholesterol ratios including these suggestions:

  • Choose olive oil instead of margarine, butter or mayonnaise.
  • A daily serving of nuts or avocado promotes a healthier cholesterol ratio.
  • A Mediterranean style-eating pattern also promotes health ratios.

You are what you eat in chronic pain

Over the last decade we have seen a flood of evidence linking a poor diet with chronic health conditions. But what about chronic pain? Until recently the role of diet in relation to chronic pain in most areas has been marginalised particularly when it comes to treatment strategy. However, we are now seeing some directly links between diet and pain and the importance of diet is emerging. The research highlights below are from a recent neuroscience conference in the USA:

Omega 3 and 6

A diet high in omega 6 from processed and fried foods may directly interact with danger sensing neurons by boosting the activity of a protein called TRPV1. This protein detects hot temperatures and potentially harmful substances such as capsaicin from chili peppers (e.g. hand under boiling water, hot chili burning skin). Researchers have hypothesised that a diet rich in processed omega 6 fatty acids leads to increased pain by interacting with these proteins and increasing their activity.

By contrast other research has shown that a diet rich in omega 3 fish oils may have the potential to improve pain thresholds and reduce sensitivity in neuropathic pain in a diabetes model.

Dietary Pattern

An interesting study looking at the impact of diet on recovery times after injury compared the Standard American Diet (SAD) to both an Anti-Inflammatory Diet (AID) rich in omega 3 and plant-based foods and a regular diet. The results showed that a regular diet shorted recovery by up to 50% and an AID even sooner. However, when a regular diet was eaten during the week but a SAD eaten on weekends, recovery times were the same as eating a SAD all week.

Gut Bacteria

Following up from the above researchers then wanted to determine how the AID makes such a positive impact on recovery times. The key may be gut bacteria. Those eating an AID have a broader category of healthy bacteria compared to those eating a SAD. Essentially the percentage of bacteria in the gut is skewed towards bacteria that promote inflammation in a SAD.

Sugar & Sweeteners

By now we all know sugar is addictive but researchers have also shown it impacts on the pain-relieving effect of medication, specifically oxycondone (an opioid). Animal research warning! Rats fed a diet high in corn syrup had a blunted response to oxycondone (i.e. less pain relief) and in addition had a increased risk of addiction to the drug itself.

On a practical level take outs from the above research could be distilled as below:

  • Shift the balance of fatty acids in your diet by consuming fresh, cold pressed vegetable oils such as olive oil (as opposed to seed oils) and eat oily fish regularly (salmon, tuna, mackerel, anchovies and trout). I choose the smaller fish to reduce the risk of environmental toxins.
  • Avoid processed oils and foods generally.
  • Have an anti-inflammatory eating pattern. For those in acute or chronic pain it might mean eating this way for 95% for a period of time at least. For general health, choose to eat an AID for at least 19 of 21 meals a week (3 meals x 7 days).
  • Take a leaf out of Sarah Wilson’s book/s and give up or at least reduce sugar. It is addictive and may increase addiction to other substances.
  • Support your microbiome with foods rich in polyphenols and prebiotics e.g. wild rice, blueberries, stewed apple, cooked and cooled starchy vegetables and rice, garlic, onion and a wide variety of vegetables.

Stress impacts our gut bugs

gut bugsA new study from Nature Scientific Reports indicates that stress may be as unhealthy to our gut microbiota as a bad diet. The study was carried out on animals but may have implications for humans. The researchers set out to evaluate the factors that impact on the gut microbiota and found that female mice exposed to stress showed significant changes to their microbiota: the changes in the composition of gut bugs looked like they had been eating a high fat diet.

While we often think that stress has a mostly psychological effect, this study highlights the physical impacts. Interestingly male mice didn’t respond in the same way as females. As opposed to the female mice, higher anxiety and a negative stress response was seen in male mice fed on a high-fat diet. Only in the female mice did stress shift the microbiota as if the animals were being fed high fat foods.

So apart from eating a gut-healthy diet, stress management may be a powerful way of helping to maintain a healthy gut microbiota, thus reducing the risk of the growing list of diseases linked to gut dysbiosis.

Orange glasses improve sleep

Over the last few years my sleep can go through bad patches and during these times I can have difficulty falling asleep or wake through the night. I no longer feel stressed by this as I once did and I have done much to improve my sleep however I am always interested in research about improving sleep quantity and quality. So as someone that can be found on my ipad watching SBS Nordic Noir of an evening I read this recent trial published in Ophthalmic & Physiological Optics with interest.

The study followed 22 people between the ages of 17 and 42. For 2 weeks the participants wore blue light blocking glasses for 3 hours before bed while participating in usual digital screen activities (TV, phone, tablet or other). The outcomes were significant and showed an average of 58% increase in melatonin levels, an effect that is greater than over the counter melatonin supplements. Melatonin is our key sleep hormone and it signals to our bodies when it is time to sleep. During the trial the participants reported better sleep, decreased sleep latency (faster sleep onset) and increased sleep duration of up to 24 minutes per night.

Blue light exposure comes from sunlight and LED devices. Exposure during the day is healthy as it boosts alertness and regulates our internal body clock (circadian rhythm) essentially telling us when to sleep and when to wake. However artificial blue light exposure at night has been shown to reduce sleep quality and quantity, as well as the regenerative quality of sleep. Artificial blue light activates photoreceptors in the brain which suppress melatonin, which is ideal during the day but at night impacts on our sleep regulation. Less melatonin is produced or it is produced later in the evening, which in the short term means we get reduced sleep signals or get them later in the evening and in the long term can disrupt sleep and wake cycles.

Based on this study I am participating in my own clinical trial with an ‘n’ of 1 (n = 1 means there is only one person in the trial so this is a bit of a nerdy research joke). A very un-cool pair of orange glasses arrived in the mail and I have been wearing them as per the trial over the last week. They look particularly good over my reading glasses! The first few nights of wearing them I was feeling sleepy up to an hour earlier than usual. Time will tell if they are effective in the long term but when I give into the sleep signals I am getting to sleep earlier and thus sleeping longer overnight. So far so good. I think orange glasses may just become de rigueur in my household!

Black Seed Oil – the skin wunderkind

nigellaCorticosteroids are a cornerstone of topical treatment in most inflammatory skin conditions. However, this treatment comes with the potential for significant risk including thinning of the skin, development of spider veins and suppression of normal stress responses via the hypothalamic-pituitary-adrenal axis. So recently when a client of mine (thank you!) sent through a study outlining the use of Nigella sativa seed oil (Black seed oil) on psoriasis-like lesions I was thrilled. I then went searching for other reports of its use for similar conditions and came up with lots of research with great potential.

Black seed oil is native to Asia and has been used traditionally in the Middle East and Southeast Asia as a topical and oral herbal medicine. Studies on Black seed oil have showed that it has a wide range of potentially therapeutic effects: immune-stimulatory, anti-inflammatory, antimicrobial and antioxidant. Even more significant, the specific potential of Black seed oil with regard to skin health is extensive:

  • Anti-microbial – studies have shown Black seed oil to be anti-microbial against a wide range of microbes, particularly multiple-antibiotic resistant bacteria (Staphylococcus aureas, pseudomonas and e. coli). A study in newborn babies with pustular Staph infections showed that use of a low dose 33% concentration of Black seed oil was nearly as effective as a standard topical antibiotic with no side effects.
  • Anti-fungal against Candida yeasts.
  • Promotes wound healing by reducing inflammation and local infection, allowing the skin to heal.
  • Anti-inflammatory in a range of skin conditions including psoriasis and acne (10% lotion over 2 months reduced lesion counts and resulted in satisfaction of 67% of patients).
  • Black seed oil inhibits histamine release in the skin and as such can be used to reduce hypersensitivity reactions.
  • A study in hand eczema showed significant improvement in quality of life and severity when Black seed oil ointment was applied twice daily for 4 weeks.
  • Cosmetically it also showed benefit when combined with Borage oil, reducing skin irritation and improving skin hydration and barrier function when compared with a placebo.

Some of these studies don’t outline specific topical concentrations and none of the studies compare it to corticosteroids however, the risk profile of Black seed oil is minimal. So overall I think the potential benefit for such a wide range of skin conditions is heartening and assessing individual clinical benefit may be the key until we see more specific research in this area. If you have used Black seed oil to help manage a skin condition, I would love to hear from you – please comment below.

Holistic Pain Management – Part 1

In this podcast I discuss the origins and assessment of chronic pain with Andrew Whitfield-Cook. It was important for me to get across that chronic pain persists for reasons beyond peripheral input. While that may be part of the issue, or even the origin, the reason chronic pain persists is about a myriad of factors including central nervous system input, neuro-inflammation, attention, beliefs, emotions, lack of human connection to name a few. This podcast discusses some of these factors.
