Healthy Carbohydrate Challenge

Seeing the words 'healthy' and 'carbohydrates' can be rare these days - depending on where you're getting your nutrition info. I see a lot of critiques of the Acceptable Macronutrient Distribution Ranges (AMDRs), set by the Institute of Medicine. So let's take a look at those:

AMDRs (1):
Carbohydrates, males/females, 9-70: 45-65% of total calories
Fat, males/females, 19-70: 25-35% of total calories
Protein, males/female, 19-70: 10-35%

My challenge, to myself, is to incorporate a variety of carbohydrate sources. It's very easy to get stuck in a carbohydrate rut... one might say a carbohydrut (okay i'll stop). But seriously, it seems like you say carbohydrate and people automatically think, "grains"! There's so much more to carbohydrates and the reasons behind the AMDR values.

Carbohydrates are pretty unique to plants - besides muscle glycogen and dairy sugars - and with plants come an array of vitamins, minerals, antioxidants and phytonutrients. This isn't to put animal products down, but rather to acknowledge the benefits of basing your diets around plants. I also don't want to come off as a grain-hater or to say that there aren't all of the above in grains as well, but the nutrient profiles of carbohydrates vary with the source, and just sticking to grains, even whole grains, isn't necessarily optimal.

The advice to eat low-fat years ago was supposed to lead to increased intake of vegetables, fruits, whole grains, beans, and lean meats. This was distorted by the food industry and now people love to overly demonize carbohydrates - do they deserve that reputation though?

So my challenge? To diversify, and stick to the recommended ranges!  Well i'm a runner/swimmer, and mix in some yoga and lifting. On days I do more intense cardio, I stick closer to 55-60% carbohydrates. On a yoga day, I'll drop to 45% and swap in a serving of nuts/seeds for a higher glycemic load carb - for my thought on glycemic response, see here. I vary it only slightly, and focus mainly on the # of calories I'm eating. How am I going to source those carbohydrates?

Lentils/chickpeas - great source of protein and iron as well
*Tempeh - loaded with fiber, healthy fats, protein, + iron/calcium
Quinoa - great source of lysine (which most grains are low in) and iron/protein
Sweet potato - great source of beta carotene
Squash
Mushrooms
Peppers
Beets
Carrots
Farro
Ezekiel Bread - cinnamon raisin ezekiel bread with almond butter +flax/hemp is the best breakfast
Peas (jk I hate peas but you can try them!)
Tomatoes - sun dried and tomato sauce
Fruits - I go for frozen mangoes and berries myself
*I choose fermented beans/grains wherever possible

This is by no means an exhaustive list - but I hope it exemplifies the variety of carbohydrate-dense sources there are out there. No research suggests carbs or whole grains in and of themselves are bad  (given you don't have a medical condition that limits/excludes some of these products) ; the bigger issue is that a single bagel has gone from a 3'' to 6'' diameter in the past 20 years, and 1 serving of grains to about 3 (2). Portion distortion is a real and present danger.

Which carbohydrate sources do you choose?

Beware the Meta-Analysis: Fat, Guidelines, and Biases

Headlines were abuzz this week, reporting that a new review of randomized controlled trials at the time of the low-fat guidelines didn't support their institution. Time , Business Insider , and The Verge all covered the topic with sensationalist headlines (e.g. 'We should never have told people to stop eating fat' #weneverdid). I won't spend every part of this blog picking apart the entire meta-analysis; you can read it over at the open access journal, BMJ Open Heart (1) -- (note, for myself, i'm adding an extra level of skepticism for anything that gets published in this journal). I'm also not going to defend low-fat diets either, but rather, use this meta-analysis to point out some critical shortcomings in nutritional sciences research, and note that we should be wary of meta-analyses when it comes to diet trials. First off, let's discuss randomized controlled trials (RCTs). They are considered the gold standard in biomedical research; in the hierarc...

On PURE

The PURE macronutrients studies were published in the Lancet journals today and the headlines / commentaries are reminding us that everything we thought we think we were told we knew about nutrition is wrong/misguided, etc. Below is my non-epidemiologist's run down of what happened in PURE. A couple papers came out related to PURE, but the one causing the most buzz is the relationship of the macronutrients to mortality. With a median follow up of 7.4 years, 5796 people died and 4784 had a major cardiovascular event (stroke, MCI). The paper modeled the impacts of self reported dietary carbohydrate, total fat, protein, monounsaturated (MUFA), saturated (SFA), and polyunsaturated (PUFA) fatty acid intakes on cardiovascular (CVD), non-CVD and total mortality; all macros were represented as a percentage of total self reported energy intakes and reported/analyzed in quintiles (energy intakes between 500-5000kcals/day were considered plausible..). All dietary data was determined by a ...

The Singling Out of Golden Rice

I saw earlier today that  Steven Novella, MD, over at Neurlogica blog  covered some controversy surrounding Golden Rice and it reminded me I had some thoughts to throw down about the GR issue. Dr Novella's post was in response to some of the claims made in a comment written on his post about a recent Nature Biotechnology paper on crop biofortification .  This is an area I've seen a lot of commentary on, no doubt because Golden Rice is a transgenic crop. Dr Novella makes some good commentary in his post and I suggest reading it ( here ) before the rest of this post - it will contain some additional thoughts to Dr Novella's. Dr Novella did a great job fielding the opposition to Golden Rice, which is something I've always found rather odd - I guess if you're vehemently opposed to a technology that represents a diverse array of methods (there's not one way to genetically engineer a plant) and innumerable potential outcomes (plants can be engineered for any number ...
