Nigel’s diet… why so much meat?

Thanks to Nigel there was an explosion of interest in my blog post last week – and with it, a lot of questions around including certain foods in my recommendations. One I’d specifically like to address is the inclusion of animal protein (or red meat) in (what some viewed as) large amounts. Now for those who have been reading my blog for a while, this will be covering old ground as I know I’ve talked about elements of this previously. However Nigel’s documentary series has sparked much more interest in what to eat and, as the questions I got suggest, a lot of this information is new ground for many – so I’m happy to delve further into some of these issues and explain why I encourage the inclusion of red meat in the diet.

The first point to make here is that a whole-food/paleo diet (as I recommended Nigel eat) is not a meat heavy diet – it’s good to dispel that myth immediately. Sure, some doing ‘paleo’, include large amounts of meat at every meal at the expense of vegetables; however that is not what most people I know do. In fact, I eat more vegetables than some vegetarians I know. The inclusion of small amounts of meat or animal protein at each meal helps stabilise blood sugars and prevents overeating due to energy crashes. In addition, these foods contain complete proteins that are essential for the repair and rebuild of musculoskeletal tissue, they provide (amongst others) iron, zinc, iodine (fish) which are important for over 200 metabolic processes in the body important in brain, gut, liver and thyroid health, and deliver important antioxidants such as co-enzyme q 10 for heart health (and great skin!) Alongside these are the fat soluble vitamins (A, D, K) and essential fats (omega 3 fatty acids, monounsaturated fats and saturated fats) and cholesterol that form the backbone of many hormones and messenger enzymes that are responsible for delivering instructions throughout the body.

I’ve taken a broad-brush approach to the many benefits of including animal protein in the diet, but one thing I want to point out is that it’s not the eye fillet steak and the boneless, skinless, (tasteless) chicken breast that I’m talking about – the meat that is closest to the bone is the most healthy meat. Yes it’s fattier – but that’s a good thing (see above re: essential fats). There is beginning to be a trend of nose-to-tail eating now, making many of the offcuts of meat that were often binned now available to be purchased and used at the fraction of the price of an eye fillet steak (if people are willing to try them!). In New Zealand we have predominantly grass fed meat, which means we are largely protected from meat that has been grain fed. Grain fed cattle produces meat with a higher fat content but its fatty acid profile is not ideal – higher in omega 6 fats and higher intramuscular triglycerides (pro-inflammatory). The grain affects the health of the cattle, with more risk of infection and harmful bacteria which have downstream consequences to the quality of the meat we find in our food supply. While in NZ cattle are ‘finished off’ with grain, after a Twitter conversation I had the other week I believe the health consequences of this for us are negligible – though am happy to stand corrected!

And then there’s the issue of meat and cancer. And meat and heart disease. And meat and [insert health condition here that suggests you are a medium-rare steak away from certain death]. The problem with the media snippets most people are exposed to is that the finer (read: important) details are overlooked in amongst the rush to print that meat is as bad for you as smoking. Well (gasp) it’s not. Firstly, any research that suggests meat is adversely linked to any of the aforementioned conditions is association, not causational. These research studies cannot determine cause and effect and are not designed to do so. Secondly, many of the large trials asked participants to report their retrospective meat intake over a 6-10 year period once, in a questionnaire format (many people I know struggle to tell me what they ate last week). Thirdly, the distinction between actual meat and that which is found in a hamburger (for example) or even a meat sandwich in some cases is not made. There is a vast difference in quality between a rump steak and a sizzler (not to mention the latter is only around 45 percent meat and isn’t legally allowed to be called a sausage). People seldom eat a hamburger without a bun (this was before the advent of an ‘oxygen’ burger from Burger Fuel) and lumping a person who eats burgers five times per week (and upsizing with the fries and Coke) in the same category as someone who dines on eye fillet at a Pete Evan’s paleo restaurant five nights a week is problematic. Of course, I’m speculating here as to the overall diet quality of participants – but that’s all I can do as these important details pertaining to other nutrients known to affect health (i.e. processed refined carbohydrates, industrial seed oils) aren’t known. Many other lifestyle factors that contribute to poor health (such as a low level of physical activity, smoking, higher alcohol intake) are also seen in those with the highest intake of red meat and in some instances there wasn’t a linear relationship between meat intake and health (or death….) with the death rate falling in between those with the lowest intake and those with the highest intake (when split into groups according to overall consumption patterns.) These details mean little however when it comes to health reporting in the media. Nothing sells like sensationalism, and if we can draw parallels between red meat consumption and smoking then you don’t even need consumers to read the article to guarantee you’d have made an impact. Again, this is my Women’s Weekly overview; for a far more eloquent and in-depth critique of this, go to Zoe Harcombe’s review or Jamie Scott’s blog post discussing this issue.

Another big pushback against the inclusion of meat is from an ethical and sustainability perspective. Now I’m not at all suggesting that people who choose not to consume animal products based on their moral standpoint should reconsider. This is a judgement call I have no business in commenting on. However for others, thankfully the availability of free range meat now accessible at relatively cheaper cost is increasing. Demand also affects supply, and the more we ask for free range meat and eggs, the more the price will be driven down (especially considering its not essential to be choosing eye fillet for every meal). Another argument against encouraging meat consumption is that it’s not sustainable for the environment, with more demand for meat increasing the fossil fuel used to produce it, the water usage required and an increase in the methane emissions (and the carbon footprint). If we put it into perspective, most of what we do has a carbon footprint. Grain-feeding cattle may (or may not) be more resource intensive (and have a larger footprint) given what is necessary to grow the grains to be fed to the cattle as opposed to raising cows on a grass field. And promoting a vegetarian diet based on this argument is flawed given the resources required to feed the world on vegetables.


Turn your heating off a put on a jersey instead.

So that’s my stance on including animal protein (and red meat) in the diet. There are many reasons why people choose not to include red meat in their diet – but if they are based on optimising nutrient intake, protection from later chronic illness, or from a sustainability perspective, then perhaps reconsidering it wouldn’t go amiss.


Building beautiful from the inside out

On Wednesday night I’ll be talking with over 100 beautiful women at the Women’s pamper evening in Newmarket that is being hosted by Auckland’s original Paleo café, Wilder and Hunt. I’ll be sharing what I know are the building blocks of beauty from a nutrition perspective.

What makes a woman beautiful? Print and digital media influence what we perceive as beautiful in a woman and objectively speaking, we aren’t all going to agree – beauty is, after all, in the eye of the beholder. If you look through the last 50 years of beauty as defined by the media there is a definite change in the physical features of woman – from Marilyn Monroe with a softer, curvier shape, to Twiggy, whose name aptly describes her physical features, to Elle Macpherson (The Body who, in my opinion, is more gorgeous now than the early 90s and her supermodel days) to Kate Moss. The focus on a women’s shape has largely been the determining factor, and the changing shape of a beautiful woman is telling of society’s acceptance of messages that are portrayed around beauty. While once we were bombarded with the ‘thin is in’ message, this has largely been replaced by images of a muscular yet equally lean woman with ‘strong is the new skinny’ as the tag line. Both, for the majority of woman, are unattainable and – if achieved – unsustainable in the long term. This definition of ‘the body beautiful’ is largely created from the narrow perspective of industry, media and the thousands of available diet and beauty products that try and sell you a magic bullet to solve your perceived beauty woes.

Body shapes aside, there are far more salient features that (to my mind) determine what makes a woman beautiful. We all know what makes a woman beautiful – even if you don’t think you ‘know’ or haven’t quite put your finger on why someone who might not be fit this narrow definition of beautiful but you find them attractive all the same.  It’s not their body size, their haircut, their muscle tone or the make up they are wearing. It’s the sparkle in their eyes, it’s the smile on their face, and it’s a sense of calm and confidence. It’s the glow of their skin and the condition of their hair. We know that beauty comes from within and this emanates health. How often have you met someone who you initially evaluate as attractive (because, let’s face it, we all make a judgment on someone upon meeting them). Then as you get talking to them this can change by (occasionally) what they say, but more by their body language, their facial expression, the lack of warmth. What makes a person, anyone, attractive, is the type of person they are – not what they look like. And what you eat plays a large part in that.

Beauty product manufacturers know that beauty comes from the inside out -however they deal in the superficial. They spend years and have big budgets to research ingredients for their top line products to ensure they help nurture good skin health. Beauty isn’t just about our skin, but one of the first places that reflect good health is certainly our skin. The skin is the body’s largest organ, is made up predominantly of collagen and reflects the health of our cells. The time it takes for our cells to turn over and regenerate increases with age, and goes from a few weeks to a few months. It’s not just chronological age though. If we don’t have the available nutrients to nurture good health from the inside out, then no amount of expensive skin cream is going to cover up the signs of a poor diet. The older we get, the slower our cells regenerate and turn over. At any age, however, this process can slow down if you don’t have a diet that supports healthy cell metabolism. You can encourage cell turnover through beauty routines that include exofoliation or microdermabrasion, however your best line of defence has to be your diet.

How can you easily find out which nutrients are important in cell health – take a look at the active ingredients in many skin care products. Vitamins A, C, E, along with omega 3 fatty acids have been found to be protective against inflammation in the skin and these may protect the whole body from sun damage – rather than the topical protection that sunscreen provides  These nutrients also play a valuable role in gut health, reducing oxidative stress in the body and (omega 3’s in particular) help with the elasticity of our arteries and cell walls – protecting against arterial stiffness and subsequent narrowing of the arteries. In addition, vitamin A works much better in the presence of vitamin K2 for encouraging cell renewal, and the antioxidant activity of both C and E is enhanced when they are delivered together

Likewise zinc, a mineral found in animal protein (the most available form in the diet) is essential for wound healing, cell regeneration and synthesis, and again plays a role in gut health.  A healthy gut is important for the absorption of all of the nutrients to ensure they are available to be utilized in the body. Co-enzyme q 10 is often touted as an essential ingredient in skin care and that is well warranted – research points to deficiencies in this leading to increased levels of reactive oxidative species (or oxidative stress) in the body due to it’s role as an antioxidant. And another important cofactor in skin (and overall health) is collagen – you could take Imedeen capsules – the original expensive skin care pill – or eat slow cooked meat or bone broth where the collagen has broken down and glycine is released – yet another important co-factor in our digestive health.

You know what? There are many different antioxidants, phytochemicals, vitamins and minerals that are responsible for cell health and regeneration in the body. I’ve scratched the surface here. But the main reason for writing this is to point out that the main building blocks for beauty aren’t purchased in a cream or a pill, nor are they necessarily sourced as an addition to an otherwise awesome diet. The co-factors responsible for building you beautiful are found in your everyday food choices: your fresh, seasonal vegetables, fruit, grass fed meat, free range eggs, full fat dairy and nuts and seeds. For otherwise healthy people, the benefit of whole food will shine through the skin, the eyes and the hair. In addition to that, the benefits of this for balancing stress and sex hormones, helping both energy levels and mood, the enigmatic aura that makes someone beautiful will shine through. And that’s the real benefit – how you feel. You can’t buy that in a bottle.
