“How Do I Know When It’s Working?” A Quick Troubleshooting Guide to Paleo

April 15, 2013 in FAQ, FAQ, How To Get Started

yoga1It’s a question that many people new to paleolithic nutrition ask either while they are going through that initial adjustment period (especially when jumping into paleo with both feet but also with gradual transitions) or as the months wear on and the difference is not as magical as anticipated.  How do I know when it’s working?  When will I start to lose tons of weight and have lots of energy?  When will my health conditions miraculously disappear?

Well, the answer is “it depends”.

How different did you eat before committing to paleolithic nutrition?  Generally, the more different you are eating now to before you discovered paleo, the harder and longer your adjustment period.  This is especially true if you ate a lot of carbohydrates before.  It can take up to a month for your body to switch over to a metabolism that runs better on fat and in the meantime, you may feel tired, lethargic, have headaches, and generally feel pretty terrible.  But, this isn’t true for everyone.  And of course, the opposite can also be true:  some people are made so sick by the foods they were eating before that they notice an instant improvement to their health.

What health issues are you challenged with?  In my personal experience, most gut health issues will improve dramatically the first couple of weeks on paleo and then continue to improve slowly over the next six months as your gut continues to heal (for more posts on gut health, see here and here).  Issues relating to inflammation typically take longer to show significant improvement depending on how well you are sleeping and managing your stress (typically another month or two).  Remember that for many health issues, you need to address all of the tenants of a paleolithic lifestyle (get good sleep, manage stress, get outside).

Are you in autoimmune denial?  I was.  While out-of-the-box paleo tackled most of my health issues, I still had unresolved autoimmune issues even after four months of strict paleolithic nutrition.  I had to do the autoimmune protocol (I’ve written about the autoimmune protocol extensively and this is also the topic of my book), in which you also exclude all the gray area foods.  If you have been eating a strict paleolithic diet for two months and are still dealing with health issues, you might have to do this too.  The good news is that after a few months of no eggs, no nuts, no seeds, no nightshades, no alcohol, no NSAIDs, low caffeine and no cheating, with a concurrent focus on eating extremely nutrient-dense foods (lots of vegetables, grass-fed meat, organ meat, fish and bone broth), most people can add at least some of those things back in.

Is your gut in REALLY bad shape?  It is possible that your gut was very leaky before you started paleo, so healing is just plain ol’ going to take a while.  Especially, if you suspect that you have Small Intestinal Bacterial Overgrowth or extensive gut damage, you’ll need to focus on Repairing The Gut, which can take 6 months to 2 years (although you should see continuous gradual improvement).  For all of the posts I’ve written on gut health, click here.

stomach acidHow is your digestion?  You might need to add some digestive support supplements for a little while to help your body heal.  These include digestive enzymes, ox bile, and stomach acid supplements (which are contraindicated for those with ulcers, blood clotting disorders, or taking NSAIDs).  Digestive enzymes and ox bile, while they can be expensive, are generally very safe to take as directed on the bottle (just make sure you actually eat once you take digestive enzymes because taking them and then not eating can cause damage to your gut).  If you are interested in a stomach acid supplement, check out my post on stomach acid here and this post by Steve Wright.

Do you have unknown food sensitivities?  If you’ve had a leaky gut for some time, you may have food sensitivities that you are unaware of.  Many alternative health care practitioners will order an IgG and/or IgA antibody screen which tests for food sensitivities.  The good news is that if you leave those foods out of your diet for a while, you can usually add them back in after your gut has fully healed.  If you have symptoms of Irritable Bowel Syndrome (like diarrhea, constipation, gas, bloating, acid reflux), another possibility is a FODMAP sensitivity.  Other potential culprits include salicylate sensitivity and food allergies (such as latex allergies, citrus, fish and shellfish, tree nuts, eggs, and dairy).

Do you need liver detox support? If you had/have an overgrowth of bacteria or yeast in your gut that are now dying off in great numbers, your liver might be working in overdrive.  B-vitamins (rich in red meat and organ meat), sulfur (rich in cruciferous vegetables and vegetables from the allium family), selenium (rich in seafood and organ meat) molybdenum (rich in organ meat) are important to support the liver.  Milk thistle (extract or tea) may also be helpful.  Choosing foods rich in these substances (or supplements) to help support liver detox is also useful for anyone losing weight, especially if the weight is coming off quickly.  This is because the body uses the fat tissues to store some toxins and excess hormones like estrogen (which gets them safely out of the body’s circulation) and rapid weigh loss has the potential to release these putting an additional strain on the liver.

Are you sleeping enough?  Yes, this has nothing to do with diet.  But sleep has a profound effect on every system in your body and if you are not getting enough of it, you can’t heal properly.  Aim for 8-10 hours per night in a pitch black room (see this post if you’re having trouble getting good sleep).  You can read more about the importance of sleep on the immune system in this teaser excerpt from The Paleo Approach.

Are you stressed? If you are not taking adequate measures to manage your stress (like getting activity but avoiding excessively strenuous exercise, spending time outside, having fun, getting enough sleep and developing strategies to manage psychological stressors), then your stress hormones might be out of whack.  If you have been under high stress for a long time and have trouble sleeping, you may have adrenal fatigue.  Both www.RobbWolf.com and www.BalancedBites.com have lots of great suggestions for healing from adrenal fatigue.

Did you go too low carb? What types of carbs (fruit versus starchy vegetables versus both versus neither) and how many carbs we should eat (varying from ketogenic diets and 20g per day to plenty of “safe starches” and upwards of 300g per day) is probably the most hotly debated topic within the paleo community.  One of the reasons for there being no clear answer as to what is best is that the carb intake of historically-studied and modern hunter-gatherer populations varies wildly.  On one end of the extreme are the Eskimos, who consume a diet composed approximately of 50% fat, 35% protein and 15% carbohydrate.  On the other end of the extreme are the Kitavans, who consume a diet composed approximately of 20% fat, 10% protein and 70% carbohydrate.  And of course, everything in between.  This probably reflects the fact that macronutrient ratios are not as important as food quality and nutrient density.  So, if your introduction to the concept of paleo was through a resource that expounded on the benefits of low carb, it is important to understand that this view is not representative of the entire paleo community and no consensus exists.  It’s also important to understand, that while blood sugar regulation is extremely important, going too low carb can be tough on your thyroid and can decrease leptin sensitivity (see this post and this post).  Also, eating adequate carbohydrates and especially insoluble fiber is important for proper regulation of ghrelin levels (see this post).  So, what is a good carbohydrate intake?  That’s actually highly individual (you can read this series of posts about optimizing your carb intake here, here and here), but if you are not feeling very good on a standard paleo diet, adding a little fruit or starchy vegetables is a good idea to try.

Are you inappropriately IFing? There are many enthusiastic supporters of Intermittent Fasting, but it’s important to understand that this is only appropriate for very healthy people.  If your sleep is not great, if your stress in not managed, if you are substantially overweight or if you have any kind of chronic disease, skipping breakfast (or breakfast and lunch) can cause dysregulated cortisol and undermine your other efforts.  This is not something to experiment with early on in your paleo journey.

What are your goals and how far away from them are you?  If you have a lot of weight to lose, you will probably notice a big drop in weight fairly quickly.  This will be mostly water weight, but don’t worry, fat is also being burned and you should eventually settle down into some nice steady weight loss (slow and steady wins the race, so there is no reason to be frustrated with weight loss if you are “only” losing a half pound per week-that’s actually very healthy!).  When your body seems resistant to weight loss, try addressing sleep quality and stress levels, but also be aware of the impact of female hormones and hunger hormones (levels and sensitivity).  For more tips and tricks for losing weight, see this post.

gray foodsAre you truly complying with paleolithic nutrition?  There are few things worse than being “almost paleo” (depending on your health challenges and what “almost” actually means for you).  While many people can successfully navigate the murky waters of cheats and occasional gluten consumption, if you are asking the question “when will I feel fabulous” while not actually following a paleo diet as strictly as you can, then you might be a person who just can’t cheat or tolerate occasional gluten exposure.  And from a metabolism, hormone and taste-bud adaptation standpoint, allowing yourself the occasional slice of pizza or pie a la mode can really derail your efforts to get healthy and perpetuate cravings, food addictions, and feelings of deprivation.  I advise eating very strict paleo for at least a month before you play with eating small amounts of dairy or legumes or allowing yourself cheat meals (and I recommend a lifelong avoidance of gluten for most people).  If strict paleo isn’t enough to make you feel great, look at the gray area foods in your diet (eggs, nuts, seeds, nightshades, alcohol, caffeine).  Maybe one of them is the culprit (nightshades are my number one suspect).  But if you are truly sticking to it, my guess is you are already feeling much, much better!

The Hormones of Hunger

January 29, 2013 in Hormone Regulation

I want to delve into the effects of diet and lifestyle on hunger and satiety signals in a series of upcoming posts.  I am mostly interested in the hormone dysregulation that occurs during metabolic syndrome, but also in how to optimize diet, exercise, sleep and stress management to achieve an ideal weight.

The feeling of hunger is regulated by a complex system of hormones that interact with neurotransmitters and neurotransmitter receptors within the hypothalamus region of the brain.  These hormones essentially activate or deactivate specific neurons in the hypothalamus that control hunger.  These neurons have receptors to Neuropeptide Y (NPY), the essential neurotransmitter in regulating hunger.  The hormones can increase or decrease hunger either through binding the receptors for NPY or increasing or decreasing NPY itself.  Essentially a hormone will increase hunger if its expression activates these NPY neurons whereas you will feel satiated if a hormone’s expression deactivates the NPY neurons.  The interplay between these hormones and your brain is complex and only partially understood.  However, what scientists do know about these hormones can help inform our decisions and compulsions regarding diet and other lifestyle factors. 

New hormones continue to be discovered and their roles in regulating appetite, satiety, metabolism and digestion continue to be studied.  As the full list of hunger hormones grows, understanding the complex interplay between these hormones, the types of food you eat, and the amount of muscle and fat on your body quickly becomes overwhelming.  I have tried to summarize the key players (at least as scientists currently understand them):

Hormones that tell your body you’re satiated:

Cholecystokinin (CCK) is secreted by the cells that line the duodenum (the first segment of the small intestine) when they detect the presence of fat.  This causes the release of digestive enzymes from the pancreas and bile from the gallbladder.  Increased levels of CCK signals to the stomach to slow down the speed of digestion so the small intestine can effectively digest the fats.  CKK is also a neuropeptide similar to NPY and has a direct action on neurons in the brain to signal satiety.  This is the most immediate hunger suppressing signal and is the reason why eating fat with your meals is so important.

Oxyntomodulin is released in response to protein and carbohydrates in the stomach and signals a change in energy status to the brain.  Oxyntomodulin enhances digestion by delaying gastric emptying and decreasing gastric acid secretion.

Peptide YY (PYY) is released by cells that line the jejunum, ileum (the next two segments of the small intestine) and colon in response to feeding and is especially sensitive to protein.  PYY signals to the gallbladder and pancreas to stop producing digestive enzymes.  PYY is important in increasing the efficiency of digestion and nutrient absorption after meal by slowing down gastric emptying, slowing down the speed of digestion, and increasing water and electrolyte absorption in the colon.  PYY interacts directly with NPY receptors in the hypothalamus in an inhibitory fashion, thereby turning off hunger signals.

Glucagon-Like Peptide-1 (GLP-1) is secreted in the ileum in response to carbohydrate, protein and fat.  It rapidly enters the circulation and is one of the fastest and shortest-lived satiety signals.  It inhibits acid secretion and gastric emptying in the stomach.  GLP-1 also increases insulin secretion and decreases glucagon secretion.  GLP-1 decreases hunger signals by reducing the amount of NPY.

Leptin plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism.  Leptin is released both by adipocytes (fat cells) and by the cells that line the stomach, so it signals both that the body is fed and that there is sufficient energy storage.  This appetite inhibition is long-term, in contrast to the rapid inhibition of eating by CCK and the slower suppression of hunger between meals mediated by PYY.  Leptin both rapidly inhibits NPY production and deactivates NPY neurons in the brain to signal that the body has had enough to eat, producing a feeling of satiety. It is one of the most important adipose derived hormones (read more in this post).

Adiponectin is secreted from adipose tissue into the bloodstream where it signals decreased gluconeogenesis (when the body converts fats and proteins into  glucose for energy), increased glucose uptake, lipid catabolism (breaking down of fats), triglyceride clearance (storage of fats), increased insulin sensitivity, and control of energy metabolism.  Adiponectin acts directly on NPY neurons similarly to leptin but with additive effects.

Hormones that tell your body you’re hungry:

Ghrelin is considered the main hunger hormone.  It is secreted by the cells that line the stomach when the stomach is empty and also by the pancreas when it detects low blood sugar.  Also, the liver secretes ghrelin when its glycogen storage runs low (and glucagon is high).  When ghrelin is released into the circulation, it directly activates NPY neurons to stimulate appetite.  Increased levels of ghrelin are directly associated with the sensation of hunger. It is considered the counterpart of the hormone leptin.  Importantly, ghrelin is a potent stimulator of growth hormone (GH) secretion and regulates nutrient storage, thereby linking nutrient partitioning with growth and repair processes. Ghrelin activates several anti-inflammatory pathways in the body and promotes cell regeneration thereby promoting healing, especially within the gastrointestinal tract. Ghrelin regulates glucose homeostasis through a direct action on the pancreatic islet cells (the cells that secrete insulin).  It is also important for memory function and gastrointestinal motility.

Cortisol is well-known as a stress hormone, but it has key roles in regulating metabolism and hunger.  Cortisol levels determine whether the body uses glycogen stores or triglyceride stores for energy (stored carbohydrate or stored fat).  Cortisol can also stimulate gluconeogenesis, the process of converting amino acids (proteins) and lipids (fats) into glucose in the liver.  It is believed that cortisol directly influences food consumption by acting on NPY neurons in the brain as well as affecting the levels of NPY and leptin.  Cortisol seems to have a particular effect on the desire to eat foods high in fat and sugar.  This is why stress management (which really means controlling any factor that might mess with your natural cortisol levels) is so important.

Glucagon is a hormone secreted by the pancreas when it detects low blood glucose levels (typically between meals, but this can also happen as part of that “sugar crash” after eating something very high carbohydrate).  Glucagon signals the liver to convert stored glycogen into glucose, which is released into the bloodstream, a process known as glycogenolysis.  When glycogen stores are low, high glucagon levels drive gluconeogenesis, the process of creating glucose from amino acids and fatty acids.  Increased glucagon amplifies the hunger sensation.

Insulin is secreted by the pancreas in reaction to high blood glucose levels (for more on insulin, see this post).  Insulin causes cells in the liver, muscle, and fat tissue to take up glucose (and fatty acids in the case of adipocytes) from the blood, storing it as glycogen.  While insulin is released as a result of eating carbohydrates, it paradoxically increases hunger as opposed to decreasing it.  This is caused by direct action on the NPY neurons and is the reason why eating a carbohydrate-rich meal is not as satiating as eating a meal that includes fats and proteins.  It also explains how quickly we feel hungry again after a high-sugar snack.

These hormones have important roles both in regulating aspects of digestion and signaling to the brain whether or not you need to eat.  Many of these hormones are also critical in regulating your blood sugar both after a meal and between meals (fed and fasted states).  Some of these hormones also affect other systems in the body, for example, interacting with the immune system and controlling inflammation.  Understanding how your diet and lifestyle affect these hormones will help you make choices that regulate these hormones properly, allowing yourself to listen to your hunger cues and trust that your body knows what it’s doing.  And regulating hunger hormones is a key part of healing and being healthy.

My (Slightly Modified) 21-Day Sugar Detox (and Hitting a Speed Bump on Day 1?! Seriously?!)

January 2, 2013 in 2013

I am doing my first ever 21-Day Sugar Detox.  What is this Sugar Detox of which I speak?  It is Diane Sanfilippo (of www.BalancedBites.com and Practical Paleo fame) ‘s signature program.  Three full weeks of avoiding sugars, sweeteners, dense carbohydrates (with allowances for athletes and pregnant/lactating women), and fruit.  For more information, click here.

Many people follow a Sugar Detox as a way of quickly resetting body chemistry (specifically blood sugar regulation) and sensitizing taste buds when they feel that they are riding the sugar roller coaster (intense sugar cravings that lead to sugar binges, followed by sugar highs, followed by sugar lows, followed by more cravings).  Within the paleo community, this might mean someone who has been giving into some SAD  foods, or someone who has been indulging in too much paleofied baked foods, or even someone who is just feeling like they’re fruit intake is excessive.  It is essentially a fast way to reduce sugar cravings (let’s be honest because this really only gets rid of biochemical sugar cravings and not emotional ones) and get back on the bandwagon when we feel things unraveling.

Do I feel like things are unraveling?  Actually, no.  I feel like I’ve been in completely control over my diet.  I’ve been following the autoimmune protocol very strictly, doing a great job of avoiding snacking and eating in the evenings (I’m trying to work on hunger hormone regulation here, more on this in a future post), and have indulged in very limited paleo baking over the last two weeks (mainly because I only made one kind of cookie that didn’t have eggs or nuts in them this year).

So, why am I doing the 21-Day Sugar Detox?  Sugar is inflammatory.  Fructose reduces leptin sensitivity.  Leptin helps regulate the immune system (more on this in a future post too).  I have an autoimmune disease.  I avoid starches because of SIBO, but I eat a whole lot of fruit.  I have been curious for a while whether or not that amount of fruit in my diet is helping or hurting me.

Last time I attempted to substantially reduce my fruit intake (while still not eating starchy vegetables), my body did not respond well to going so low carbohydrate (this was back in the early spring).   I had a cortisol response and found my sleep quality decreased substantially.  When I increased my carbohydrate intake, my sleep improved and I felt much better.  So, I’ve stuck with that.  But I know so much more now, and I think it’s time to try again, doing things a little differently than last time.

I figure I typically eat between 100g and 150g of carbohydrates (total, not net) per day, predominantly from fruit and non-starchy vegetables; but a little honey or maple syrup sneak in here and there.  I think this is very healthy for most people and I don’t think that most people really need to limit fruit (unless you are dealing with inflammation, autoimmune disease, metabolic syndrome, or having strong sugar cravings).  But, I am not most people and many people with autoimmune disease reporting having a very low tolerance for fruit, especially high fructose fruit.

Going too low carbohydrate can also reduce leptin sensitivity, which would totally defeat the purpose here.  So, I will be eating plenty of non-starchy vegetables and those higher starch content veggies that I know I tolerate well (like carrots, winter squash and beets).  Quantities of beets and butternut squash are limited on the 21-Day Sugar Detox, and I will be adhering to that (because the allowance is already more than I can typically tolerate anyway).  I will also be continuing to avoid coffee (oh how I miss it though!) and working to keep my intake of caffeinated teas on the low side (my intake has crept up lately so I really need to get that in check anyway).  I will continue to use coconut oil and red palm oil as major fat sources in my diet to hopefully help avoid a cortisol response or reducing my leptin sensitivity.

Oh yeah, and I am doing this while also adhering to the autoimmune protocol.

The 21-Day Sugar Detox allows 1 green apple or 1 green-tipped banana per day.  I will be adding 1 small grapefruit to this list (and probably eating grapefruit every day instead, although just in case I crave a green apple in a couple of weeks, I’m keeping that option open).  Why grapefruit?  I have a 12-year history of chronic constipation before transitioning to a paleo diet.  I am battling SIBO and my digestion is still precarious.  I have found that eating grapefruit  improves my digestion (probably a combination of digestive enzymes in grapefruit and the acid).  I am also taking some digestive support supplements, but I really feel like going grapefruit-free would be counterproductive for me.  I also feel that grapefruit falls into the same category as green apples and green bananas: it doesn’t taste very sweet.    Grapefruit has the added benefit of being lower in sugar than either green apples or bananas, and having slightly less than half of its sugars as fructose (that beats apples but not bananas).  This is my slight modification.  The inclusion of grapefruit as an allowed fruit (but still limiting quantity).

What am I hoping to gain on the 21-Day Sugar Detox?  I am hoping to better understand the role that fruit is playing in my diet.  Is it contributing vitamins and antioxidants and helping control inflammation?  Is the sugar content contributing to inflammation?  Is my higher carbohydrate intake helping to regulate my cortisol?  Is my higher carbohydrate intake inhibiting normal regulation of my immue system?  I am not doing this to address sugar cravings.  I am not doing this to lose weight (although I’ll take it if I happen to).  I am not doing this because I believe that fruit is in any way bad for you (at least most of you).

What will I judge my success on?  Well, largely on the symptoms I associated with my autoimmune disease:  the look and itchiness of my lichen planus lesions, how my joints feel, the frequency of the mild headaches and tinnitus I sometimes get, how I’m sleeping, my energy level, my mood and my ability to handle stress.  The bigger part of this evaluation is going to be how I feel when I add more fruit back in at the end of these three weeks.

 So, I’m on Day 1 as I type this.  How is it going?  I have already hit my first speed bump.  My mom is visiting and she also loves grapefruit.  We have both been eating grapefruit every day, so we actually shared the last one for breakfast this morning.  Because there were so many other things that I had to do today, I sent my husband to the grocery store.  I instructed him to look for white grapefruit, since they are the least sweet, then pink if he couldn’t find white.  He came home with oroblancos.

I didn’t know what oroblancos were either.  They are a cross between an acidless pomelo and a white grapefruit.  They look alot like slightly green grapefruit, but have a super thick peel so the fruit inside is the size of an orange, if that.  According to Wikipedia, they are sweeter than white grapefruit.  I nearly cried when I read that.  I also closed some doors a little more forcefully than normal.  Now I have no grapefruit in the house (nor green enough bananas nor green apples) and I’m on Day 1 and I won’ t have time to run out to the store for a couple of days.

My mother came to the rescue.  She peeled and ate an oroblanco with her lunch.  She made such a face at how tart they are, that I agreed to try a segment.  Well, they are slightly sweeter than white grapefruit, but they are NOT sweet.  Probably about the same as or slightly tarter than the pink grapefruit I’ve been buying.  I also don’t like them as much as grapefruit.  I figure that’s actually completely in line with 21-Day Sugar Detox philosophy.

So, I’m going to include 1 small grapefruit OR 1 oroblanco.  I don’t know if oroblancos will help my digestion as much as grapefruit do, but I figure I can make do for a couple of days until I have time to go out shopping and buy actual grapefruit.  So, a speed bump, but not a calamity (even if it felt like one for about twenty minutes).

As mentioned in my New Year’s post, I am going to be the featured blogger for January on The 21-Day Sugar Detox Blog.  I also posted photos my meals today on Facebook (I know many people are interested in how do you eat AIP and 21-Day Sugar Detox?!) and will try to keep that up for the next three weeks as much as possible.  I will also be posting updates on my Facebook page and Twitter, on the 21-Day Sugar Detox Facebook page, and a post or two on the blog over the next few weeks about how I’m feeling, what effects I may or may not be noticing, and generally how this whole sugar detox thing is going for me.

If you are interested in joining me on this 21-Day Sugar Detox adventure, it’s not too late to start (or you could start February 1st if you wanted to too).  This is the biggest group ever and one of the reasons why it is so successful is because of the online community of people making you feel like you are not alone as you go through the (sometimes way not fun) transition to a lower sugar diet.  Solidarity!

Carbohydrate Recommendations For Kids

August 28, 2012 in Practical Tips, Practical Tips, Practical Tips, Sugar/Carbs

As adults, it can be overwhelming wading through the varying opinions on how many carbohydrates we should eat.  Many of us with a history of being overweight find that low to moderate carbohydrate consumption works very well for us.  Many others find success at either of the extremes of paleo carbohydrate intake: ketosis versus plenty carbohydrates from “safe starches”.  This is why I wrote my 3-part series on Optimizing Carbohydrate Intake for Your Body (see here, here and here).  However, this opened up the question from many of you:  what about kids?

In general, I’m not a big fan of counting macronutrients for kids (or anyone, if you can get away with it).  If you present your child with a variety of healthy foods, most kids will naturally eat what their body needs to be healthy.  However, it is the natural tendency of parents (especially parents who are trying to address their own health issues with a paleo diet) to worry about whether or not their child is getting the right amount of, well, just about everything.  It is also helpful to have some guidance as to what exactly you should put in front of your kids.  For example, is it healthy to let them eat as much fruit as they want?  I know my kids would gladly eat fruit all day!

When it comes to macronutrient ratios for kids, I think we can get a very good idea of how they should be eating by looking at the composition of human breast milk.  In prehistoric cultures, children likely received at least some breast milk until the age of 4 or 5 years, so it’s a pretty safe bet that the macronutrient ratio of breast milk is a good guide at least for kids up to that age.  Milk is considered the perfect food for growth of a young child and I believe that we can continue to use the macronutrient ratio of breast milk as a general guide for the diets of our children for as long as they are growing (after all, the macronutrient ratio of breast milk is often used to as a guide for carbohydrate consumption for adults!).

The macronutrient ratio of human breast milk is quite variable, depending on the diet of the mother, the amount the baby nurses, and the age of the baby.  There seems to be some signaling from the baby to the mother, and it is very likely that much of this variability reflects the specific dietary needs of the baby at that time.  The carbohydrate content of human breast milk varies between 57% to 70% (as a percentage of total milk solids).  Fat makes up 28-39% of milk and protein makes up about 7-10% (as a percentage of total milk solids) [1].  Translating this to a percentage of caloric intake (which is a far more familiar number for most of us) the carbohydrate content of human breast milk is 40-55%.  When these numbers are used to provide guidelines for adult carbohydrate consumption, an amount of glucose needed by the growing brain of a baby/child is subtracted (which is why The Perfect Health Diet ends up with a recommendation closer to 20-30% carbs for adults).  We don’t need to go to these lengths here (phew! because this has already been enough math for me for one day!) because kids brains continue to grow and develop, even until their mid-twenties (sorry if I just offended anyone in their early- to mid-twenties by calling them kids).

Your child’s carbohydrate need will probably vary with growth spurts, developmental spurts, and age.  On average, their carbohydrate needs will probably tend to go down as they get older (protein especially will take its place).  Caloric intake varies dramatically with growth spurts, developmental spurts and age as well, so it’s tough to convert this to a number of grams of carbohydrates your kid should be eating.  Instead, think of it this way:  to achieve 40% of their calories from carbohydrates, something like half to three quarters of their plates should be fruit and vegetables (including plenty of starchy vegetables).  The reason why 40% of calories from carbohydrates doesn’t just translate to 40% of their plate being fruits and vegetables is because non-starchy vegetables are not very carbohydrate/calorie dense (especially compared to whatever fat you may also have on the plate).

The point of this post isn’t to get you counting the carbohydrates your child is eating, but rather to point out that quite a lot of fruit and vegetables is just fine for your growing child.  And as long as they are eating some of their meat and healthy fats and you are presenting them with a variety of healthy food options (think meat, fish, organ meat, healthy fats such as avocado, olives, and coconut oil, green veggies, colorful veggies, cruciferous veggies, starchy veggies and all kinds of fruit), it’s probably not worth worrying about.
