micronutrients at macronutrient extremes

In the previous article, Which Nutrients is YOUR Diet Missing?, we looked at the micronutrients that you might be lacking when following popular dietary strategies such as vegan, Paleo, keto, or zero carb.

As a follow-up, I thought it would be interesting to look at the effect on essential micronutrients if we define our dietary approach in terms of macronutrient extremes such as low carb, high fat, high protein, high carb, or low protein.

Humans tend to think in extreme terms.  It’s easy to follow a binary approach to nutrition, but which, if any, of these are the most useful in terms of maximising the nutrition provided by our diet?

For most of my life, best practice nutrition has been defined by a fear of fat which spawned the low-fat processed food era.

And because protein is necessary for muscle growth, more must be better?

But protein is also insulinogenic, so less protein must be good.  Right?

And then of course there is low carb, which has been popular since the appearance of the Atkins diet appeared in the early 1970s.

But then there are a good number of people who still define their diet as being high carb.

All of them seem to be similarly zealous about their all-or-nothing approach.

But are any of these macronutrient extreme approaches beneficial?  And if so, which one leads us to the optimal selection of nutritious foods that will lead to health, happiness, optimal weight, and longevity?

why bother with nutrient density?

The premise of nutrient density is that we want to maximise the quantity of essential micronutrients that we need to support our bodily functions while not overdoing energy intake.

Micronutrient dense foods allow us to obtain adequate nutrition with fewer calories.  Then, with our nutrients accounted for, higher micronutrient density might just lead to higher satiety levels, reduced appetite, reduced food intake and optimal body fat levels.

At the other extreme, if we consume fewer foods with a lower nutrient density, we will likely end up needing to consume more food to obtain the nutrients we need to survive and thrive.  If our appetite drives us to keep on eating until we obtain the nutrients we need, we may end up having to consume too much energy and and end up storing unwanted energy as fat.

macronutrient comparison

In this post, we’ll look at the micronutrients provided by the highest-ranking foods when we sort the eight thousand foods in the USDA database by the most and least fat, protein, and carbs.

Approach % protein % fat % net carbs % fibre
high fat 14% 82% 3% 1%
low net carbs 33% 67% 0% 0%
most nutrient dense 49% 19% 20% 12%
high protein 77% 22% 1% 0%
least nutrient dense 7% 32% 59% 2%
low protein 1% 27% 68% 3%
low fat 8% 1% 84% 7%
high net carbs 3% 2% 92% 2%

This chart shows the macronutrient split for these extreme approaches.

fat

While low carb is still in the lead in terms of internet searches (as shown in the Google Trends data below), the ketogenic diet is becoming pretty popular these days.

The chart below shows the nutrients provided by 2000 calories of the fattiest foods.  Nutrients are expressed in terms of the percentage of the daily recommended intake (DRI), for each nutrient, per 2000 calories (i.e. a typical daily intake).

While we achieve adequate amounts of about half of the essential micronutrients with a therapeutic ketogenic diet, we may need to consider supplementing some of the harder to obtain nutrients such as vitamin C[1], vitamin D, potassium, choline, vitamin K, and magnesium.

Looking at things from the other extreme, a low-fat diet will give you a ton of vitamin C, sodium, manganese, and iron.  However, it will be harder to obtain adequate quantities of the twenty-one essential nutrients, particularly essential fatty acids.

saturated fat

These days, the US Dietary Guidelines have lifted their limit on fat and cholesterol but retained their limitation on saturated fat.  Saturated fat and trans fats remain the two nutrients that we are advised to avoid.

The chart below shows the outcome when we avoid saturated fat.  The top 10% of foods with the lowest saturated fat are lacking (i.e. < 100% DRI) in nineteen essential nutrients.

At the other extreme, foods with the most saturated fat are slightly better with seventeen essential micronutrients lacking.

As discussed in the ‘What about Saturated Fat?’ article, I think saturated fat is neither a concern nor a priority.  Saturated fat a great clean-burning fuel, but there’s no need for us to make up for the last four decades of avoidance by suddenly binging on it.

The chart below shows a comparison of the nutrient density of the quartiles of saturated fat in terms of percentage of energy.  It seems that the foods with moderate levels of saturated fat that are the most nutrient dense.

protein

Once you move past the fear of fat, the next hot topic is optimal protein levels.

The ‘high protein bros’ recommend more protein for muscle growth and satiety, while many in the low carb/keto community target lower protein levels for longevity and ketosis through minimising insulin and mTOR signalling.[2]

As shown in the chart below, when rank foods to minimise protein, we end up with only four essential nutrients meeting the recommended daily guidelines to prevent malnutrition.

At the other extreme, if we prioritise protein we end up with ten nutrients that we fall short of.  The other twenty-six essential nutrients meet the minimum recommended levels.

Not only does protein contain essential amino acids, this analysis indicates that higher protein foods generally come bundled with high amounts of vitamins and minerals, such as vitamin B-12, selenium, vitamin B-6, riboflavin and copper.

It’s one thing to talk about targeting the minimum daily protein that you can get away with if you are looking to preserve muscle in fasting or extreme calorie deprivation during long term weight loss.  It’s a whole different discussion if you’re looking to minimise protein while making up the rest of your daily energy intake with fats or carbs!

carbohydrates

The chart below shows the nutrients we obtain if we maximise energy from non-fibre digestible carbohydrates (i.e. net carbs).  This high carb approach provides adequate amounts of twelve of the essential nutrients, while still being inadequate in twenty-four essential nutrients.

The chart below shows that low carb performs better than high carb, only falling short in sixteen essential micronutrients.

One of the benefits of a low carb approach, is that it often forces the elimination of many processed foods that fill the supermarket shelves to satisfy the demand for low fat foods driven by the admonition by the for the last four decades by the ruling dietary establishment to minimise fat.

A nutrient dense diet contains less non-fibre carb than the typical diet, but some people will do better, at least for a while, on a carb restricted diet.  Another major benefit of low carb is for insulin resistant people when they can lower their blood glucose and insulin levels on a carb restricted diet.  Many people find it easier to lose excess body fat once they have restored their insulin sensitivity.

nutrient density

You’re probably wondering where all these analyses are headed.

With all of these extreme approaches being so deficient in many micronutrients, you must be thinking “I hope there is a happy ending to this story, and soon.”

The good news is that we can manipulate our food selection to maximise micronutrients.  But first, here’s something to scare you even more.

The chart below shows the outcome when we minimise the harder-to-find nutrients.  This low nutrient density approach ends up being adequate in only three essential nutrients: sodium, vitamin C and iron.

The good news is shown in the chart below, which quantifies the nutrients provided by the most nutrient dense foods when we prioritise for the harder to find nutrients.  Alpha linolenic acid (found mainly in nuts and seeds) is hard to come by in adequate quantities, however we can obtain the daily recommended intake of all the other nutrients when we prioritise the harder to find micronutrients.

comparison of nutrients adequate

It’s a little hard to present and digest this analysis clearly.  There is no agreed protocol to compare the nutrient density foods.  So I’ve tried to summarise it in a number of different ways to allow you to draw your own conclusions.

Firstly, the chart below shows the number of nutrients that each macronutrient extreme is adequate in, from the most nutrient dense at the top to the least nutrient dense at the bottom.

The chart below shows a stacked bar chart of the various nutrients in terms of % DRI.  It’s like we have added up all the above charts for each nutrient and stacked them on top of each other.  This chart demonstrates that there is a is a massive difference between the most nutrient dense and least nutrient dense approaches.  If you’re foods that have a lower nutrient density you might just be hungrier compared to if you are eating the same number of calorie of the most nutrient dense foods which will much more effectively provide you with your essential micronutrients.

But  we needn’t be too concerned about the micronutrients that are easy to obtain.  What we really care about is the nutrients that are harder to obtain.  The chart below shows the sum of the eighteen nutrients that are harder to obtain for each extreme approach.

application

It seems that thinking in terms of macronutrient extremes has some usefulness.  However, focusing on micronutrient density seems to provide an order of magnitude improvement in the level of actual nutrients provided by our food.

Maybe it’s time for a new trend?

The ‘problem’ with nutrient dense foods is that that they are so lean and contain so much fibre that it can be hard to consume enough calories to maintain weight.  You’ll just be too full!

If you are insulin sensitive and not looking to lose weight, then you could consider adding some more ‘Paleo friendly’ carbs such as beets, squash, yams, and sweet potatoes, and/or some fattier cuts of meat to fuel your activity.  If you are insulin resistant, you may need to add some fattier (but still relatively nutrient dense) foods to maintain your weight while also keeping your blood glucose and insulin levels in check.

Perhaps micronutrient density is the most important parameter to pursue in our diet.  Then with that cornerstone in place we can personalise our nutritional approach to suit our goals (e.g. weight loss, ketosis, athletic performance or healthy maintenance).

The various food lists in the table below are designed with micronutrient density as the main priority, but also consider insulin load and energy density to suit different goals.

approach average glucose waist : height
(mg/dL) (mmol/L)
therapeutic ketosis > 140 > 7.8
diabetes and nutritional ketosis 108 to 140 6.0 to 7.8
weight loss (insulin resistant) 100 to 108 5.4 to 6.0 > 0.5
weight loss (insulin sensitive) < 97 < 5.4 > 0.5
bulking < 97 < 5.4 < 0.5
nutrient dense maintenance < 97 < 5.4 < 0.5

personalisation

In the end, no one sticks to an optimal list of foods that perfectly balances their diet 100% of the time.

I’ve been working on a system that will give you feedback on YOUR current diet, identify which nutrients you are currently lacking, and which supplements or real whole foods you may need to add or subtract to optimise your nutrition.  Most people don’t eat perfectly all the time, but we could all use some help moving forward towards optimal.

which nutrients is YOUR diet missing?  

I recently took a look at which nutrients might be missing from various popular dietary approaches in preparation for a recent on nutrient density.  At a population level, the chart below shows the proportion of the US population that are deficient in various micronutrients.  Many people are not getting enough vitamin D, vitamin E, magnesium, calcium, etc.

While your body hasn’t read the World Health Organisation’s reports on the Daily Recommended Intake of the various essential nutrients,[1] it’s likely that your appetite will drive you to seek out the nutrients that are lacking.  If we are deficient in something that is required the body kicks in “nutrient hunger” and cravings that will make sure it gets what it needs.[2] [3] [4]

If you work hard to restrict your food intake to a certain dietary approach, but the body doesn’t receive the nutrients it needs, it may slow down and not function at full capacity.   By contrast, adequate nutrition, without too much energy, slows many of the modern diseases of aging such as diabetes, Alzheimer’s and cancer and improves your chance of living healthfully to a ripe old age.[5]

USDA foods database

The chart below shows the nutrients that are both easiest and hardest to obtain from the eight thousand foods in the USDA foods database.  At the bottom of this plot we have iron, various amino acids, and vitamin C, all of which are easy to obtain in adequate quantities.

However, at the top of the chart, we can see that it is much harder to obtain adequate quantities of six essential nutrients (omega 3 fatty acids, vitamin D, choline, vitamin E, and potassium).  We would obtain sufficient quantities of all the other essential nutrients if we ate just a little of each of the foods in the USDA food database.

If we want to maximise nutrient density, it makes sense to prioritise foods that contain more of the harder-to-obtain nutrients.  The chart below shows the nutrients for the top 10% of the 8000 foods in the USDA database (blue bars) when we prioritise for those.  Not only do we get an increase in the more difficult to obtain nutrients, we also get a massive boost in all nutrients.  Rather than being inadequate in six nutrients, we are now lacking only one (alpha-Linolenic acid, an Omega 3 fatty acid).

Limiting our food selection to the most nutrient dense foods makes it easier for us to consume the required nutrients without excessive energy, which is ideal if we are trying to lose fat or reduce calorie intake to slow the diseases of ageing.[6] [7]  Nutrient density becomes even more important if you’re fasting or restricting calories to achieve long term weight loss.

Optimising nutrient density

If you’re reading this, then you’re likely aware that there is a wide variety of dietary approaches that people follow to optimise their health depending on their preferences and beliefs.

I’ve tried to turn many of these beliefs about nutrition into a quantitative algorithm that we can use to evaluate and compare these approaches, and make sure we’re getting the outcome we want (e.g. low insulin, blood glucose control, nutrient density, or low/high energy density).

After testing a number of options, the three quantitative parameters that I have found the three parameters that are most useful are:

  • insulin load,
  • nutrient density, and
  • energy density.

My aim in this post is to show how considering nutrient density can improve various dietary approaches, from therapeutic ketogenic, vegan, paleo, and low fat.   This post highlights which nutrients you will most likely be lacking with each of the different nutritional approaches, which foods you can use to fill these nutritional gaps, and perhaps which supplements you may need if you are still looking for some added nutritional insurance.

There’s been a lot of talk lately by Taubes[8] and Lustig[9] about how bad sugar and fructose are, but I think these nutritive sweeteners are just extreme examples of nutrient poor foods that are highly insulinogenic and energy dense.  At the other end of the spectrum, we have foods like liver, broccoli, and spinach.  Everything else is somewhere in the middle and will support or work against your goals, whatever they may be, to different degrees.

My aim here is to help you see where each of these foods sits on that continuum and use this information to help you refine your food choices to reach your personal goals.

Therapeutic ketogenic diet

Let’s start with the therapeutic ketogenic dietary approach.   I have previously noted that a number of the issues and concerns with the ketogenic diet seem to relate to being able to obtain essential nutrients rather than consuming excessive levels of fat.[10] [11] [12]  On one hand, I’m excited that the concepts of insulin load and percentage of insulinogenic calories have been helpful for people with chronic conditions such as epilepsy, cancer, dementia, Alzheimer’s etc.  However, I think there is a risk their ultra-high fat diet will not contain the nutrients which are critically important for mitochondrial function and energy production.

The chart below shows the vitamins and minerals provided by a therapeutic ketogenic dietary approach if we simply prioritise for low insulin load (red bars)[13] in comparison to the average of all foods in the USDA database (orange bars).  If you don’t pay attention to nutrient density a therapeutic ketogenic diet can provide lower levels of nutrition.

As shown in the chart below if we ate a little of all the foods in the USDA database, we would be deficient in six essential nutrients, whereas if we follow a therapeutic ketogenic diet, we will likely be lacking in ten essential nutrients.

The chart below shows the effect of how thinking in terms of nutrient density can improve the therapeutic ketogenic dietary approach (blue bars) compared to prioritising for insulin load only (red bars).  All nutrients are boosted, particularly the harder to obtain ones.

While lots of people find that higher fat whole foods are hard to overeat, there are still some hyper palatable high fat foods that go down easily.  We talk about eating “fat to satiety”, but what happens when nutrient hunger kicks in and your body is craving more potassium, magnesium, calcium, or one of the other nutrients that are harder to obtain in a very high fat dietary approach?  If you keep on consuming large amounts of processed fats that don’t contain the nutrients you require, your appetite may not automatically turn off before you’ve consumed a lot of excess energy!

Low carb

The chart below shows the boost in nutrients when we consider nutrient density combined with a low carbohydrate approach.  It appears that, based on this analysis, that without a focus on nutrient density, a low carbohydrate diet is likely to be deficient in folate, vitamin D, choline, potassium, magnesium, pantothenic acid, calcium, vitamin E and manganese.  With a focus on nutrient dense foods, a low carb diet provides adequate amounts of the majority of nutrients.

Weight loss (insulin sensitive)

The weight loss approach is intended for people who are insulin sensitive but still have excess body fat to lose.  Foods with a lower energy density (e.g. spinach, broccoli cucumber, celery, lettuce etc) typically are harder to overeat because they are bulky.

This approach doesn’t pay any attention to insulin load because it is assumed that people using this approach are not insulin resistant and are able to maintain good blood glucose levels.  Practically, it’s also difficult to achieve a really high insulin load with these foods because they do not contain a large amount of processed carbs and are hard to overeat.

Without consideration of nutrient density, the essential fatty acids tend to be low along with vitamin B-12, choline, and tyrosine.  However, once we factor in nutrient density all these nutrients dramatically improve.

This approach may not be viable for long term maintenance due to the extremely low energy density which would make it hard to get in enough energy.  However, in the short term, it may be appropriate for a period of substantial energy restriction, and will provide maximum nutrition with a minimum amount of energy.

Zero carb

Getting adequate protein on a zero-carb approach is not a problem.  However, unless there is a major focus on organ meats, there are a large number of vitamins and minerals, such as   vitamin K, manganese, vitamin C, vitamin E, vitamin D, potassium, magnesium and calcium that may be worth supplementing.

Vegan

At the other extreme, the chart shows the nutritional analysis of the vegan diet.  The main deficiencies in a vegan approach are omega 3s and vitamin B-12, which are hard to obtain without animal products.  It may be prudent for vegans to consider fish oil supplementation and B-12 injections, or alternatively adding some seafood occasionally.

While it appears possible to obtain the recommended levels of protein, it’s hard to get very high levels of it.    If you are insulin resistant, the fat levels can be increased using added coconut products and nuts.

Higher insulin load foods for bulking

The bulking approach is designed for people who are looking to gain strength and size by combining nutrient density with more calories and insulin load.  Without consideration of nutrient density, a high insulin load means very low nutrient density foods.  However, once we factor in nutrient density, we get a range of highly nutritious foods that may be helpful if you want to gain size and strength, while still maximising health and nutrition.

Paleo

The chart below shows the nutrients provided by the Paleo approach (i.e. no processed foods, dairy or grains) both with and without consideration of nutrient density.  While ‘going Paleo’ eliminates many of the nutrient-poor processed food, it appears to be beneficial to also consider nutrient density as well in addition.

What does this all mean?

So, how do we decide which approach is best?  Unfortunately, it’s not straightforward so I’ll look at this a number of ways.

What we ideally want is to identify the foods that will provide us with high amounts of all of the nutrients.   The blue bars in the chart below represents the average of the % daily recommended intake of all the nutrients in the various approaches evaluated above, without considering nutrient density.  The orange bars represent the average minus 0.5 x the standard deviation which is a measure of reliability.  The higher the reliability the more consistent and high are the nutrients over all.

This chart shows that, in comparison to the other approaches, Paleo foods have a high and consistent level of nutrients; while the vegan and low energy density weight loss foods have high levels of some individual nutrients, but low levels of some others.  Without consideration of nutrient density, the high insulin, low carb and zero carb approaches are a bit lacking in nutrients.

Things become a little more interesting once we factor in nutrient density.  The vegan, therapeutic keto, low carb and zero carb approaches do poorly against the paleo, higher insulin load, most nutrient dense of all foods, and the lower energy density weight loss foods.

Many people will benefit on a high fat therapeutic ketogenic dietary approach, at least until their blood glucose and insulin levels normalise.  However, in time, it may be beneficial to transition to more nutrient dense foods to continue their journey towards optimal health.

As detailed in the ‘how to optimise your diet for insulin resistance’ article, I think you should eat the most nutrient dense foods your pancreas can keep up with while maintaining good blood glucose levels.  In time, someone who is highly insulin resistant may be able to progress to a more nutrient dense and more moderate fat approach if your ultimate goal is to normalise blood glucose levels and lose weight.

Food lists

If you identify with any of these goals, you may be interested in following these food lists.   If blood glucose levels are sky high or you are managing a chronic condition such as epilepsy, cancer, Alzheimer’s or dementia, you may benefit from a higher fat therapeutic keto dietary approach, for a period.  As your glucose levels come under control, you can transition to more nutrient dense foods that will also help you to achieve your weight goals.

Getting even more personal

As you can see, nutrients are provided at different levels depending on the approach.  However, most people don’t follow any dietary approach strictly, so the nutrients in your diet will be different depending on your personal habits and preferences.

Rather than trying to pick up someone else’s nutrition plan, or live by a strict list, I think it’s better to refine your current habits, emphasising the good foods, minimising the bad, and progressively trying new foods that may be beneficial.

To this end, I’ve been developing a Nutrient Optimizer algorithm that can help you refine your food choices to suit your goals.  By identifying the foods you are currently eating that align most with your current goals, which ones don’t, and which new foods perhaps you should consider.

Most current nutritional advice is driven by the avoidance of fat, particularly saturated fat, and therefore ends up being next to useless.  Calorie counting apps like MyFitnessPal does nothing but count calories, which is also of limited use.  Cron-o-meter tracks your micronutrients and can recommend foods to boost a single nutrient.  However, there doesn’t seem to be anything available that will tell you which foods will help you actually correct multiple deficiencies and  achieve a diet that is truly balanced in micronutrients.

The Nutrient Optimiser also allows you to tailor the approach to your goals, such as:  therapeutic ketosis, diabetes management, weight loss or just nutrient dense maintenance.  Food preferences like vegan, pescetarian, autoimmune, or paleo can be factored in to the recommended food lists.

At the moment, the process involves manually exporting food intake data from Cron-o-meter, then analysing it in a spreadsheet to manually generate a personalised report.  I am eager to do this as a proof-of-concept for a range of people with various goals (particularly therapeutic ketosis, vegetarian, zero carb, fruitarian) to demonstrate how it works.  So, if you’re happy to have your report shared publicly, and have a couple of weeks of Cron-o-meter data, feel free to send it to me and  have your data analysed.

In time, the plan is to automate the process via an online interface and then ideally an independent mobile app.    To keep up-to-date with progress, watch this space and check out the various analysed examples on the Marty Kendall’s Nutrient Optimiser Facebook page.

Epilogue…  limitations

For completeness, I thought it would be worth mentioning a few limitations relating to calculating nutrient density…

  1. Measuring foods in terms of calories has its own limitations as different macronutrients provide different amounts of energy (ATP) in different people. Some smart friends of mine are working on calculating ATP yield for different foods based on their macronutrient content.  I’ll happily update this analysis in terms of nutrients per ATP as soon as that data is available.  Initial indications are that people who are fat-adapted are able to use fat more efficiently (i.e. less entropy/losses in metabolism) and hence require less calories to yield the same amount of energy in the body (i.e. ATP).  Hence, it appears that it is even more important for someone following a low carb or ketogenic approach to maximise nutrient density in terms of nutrients per calorie.
  2. The official dietary reference values are based on limited research.[14] Typically, they relate to the minimum amount of a nutrient to avoid disease rather than the amount required for optimal function.  They may also vary by person (e.g. someone who is more active may need more protein) and by their diet type (e.g. someone who is on a low carb diet may need less vitamin C to process the limited amount of glucose).  Hence, I think the DRI values should be seen as a minimum.  Ideally, we want to get more than the minimum while not having to ingest too much energy.  I also don’t think nutrients are meant to come as individual vitamins and minerals in a bottle.  The nutrients required to metabolise a certain food typically come packaged in whole foods, and often work synergistically.  Taking supplements or fortifying foods will always be inferior to obtaining nutrients from whole foods.
  3. Species-specific bioavailability and anti-nutrients are contentious topics. Zero carbers will tell you that nutrients in animal based foods are more bioavailable than plant based foods, while the vegans will tell you the opposite.  To date, I haven’t been able to find useful data that would enable me to quantitatively refine the nutrient data in the USDA database regarding bioavailability.  All we currently have is a measure of the nutrients contained in the food– rather than the nutrients that make it into your body after digestion.  Again, if this data ever comes to hand, I’ll eagerly update the analysis.

Overall, I don’t think these limitations make a difference in the outcomes of the analysis.  This is not an exact science and the body doesn’t operate like a rigid machine.  Calculation of nutrient density is just a way to identify the foods that contain the most raw materials with the least amount of calories that your body can work with.

superfood salad with liver, seaweed and saurkraut

This superfood salad is from Kate Johnson of Eat, Recycle, Repeat and was published as guest blog on Sarah Ballantyne’s Paleo Mom (see recipe here).

It’s the chicken liver and the seaweed along with the sauerkraut, mustard and coconut oil that make this salad so super with a spectacular score in both the vitamins and minerals score as well as the protein quality score.
