Can L-Glutamine Cause Brain Fog? {Monday Musings}

Alyssa Luck · Dec 5, 2016 · 12 Comments

Welcome to Monday Musings! I don’t expect this to be a weekly thing, but I wanted a nifty little label to slap on posts where I’m basically just thinking out loud. Wouldn’t want to delude anyone into thinking I have all the answers, now would I?
Thanks for being here!

L-glutamine, once a lowly amino acid vying for attention among 19 siblings, has become a darling of functional medicine for its role in gut health and intestinal permeability. L-glutamine is an important fuel source for enterocytes, which are the cells lining the intestines, and there’s pretty solid evidence that L-glutamine can help strengthen the intestinal barrier.

That all sounds fantastic, right? I sure thought so, and I supplemented accordingly, on and off, for several years. But recently, some self-experimentation has led me to suspect L-glutamine of being a contributor to some pretty intense brain fog and other mental symptoms I’ve been experiencing. L-glutamine was low on my list of suspects, because I had such positive expectations of it, so it took me a while to notice an association. But the timing was there, so I decided to investigate.

Getting Enough Carbs on the Autoimmune Protocol (AIP)

Alyssa Luck · Nov 15, 2016 · 12 Comments

The Paleo Autoimmune Protocol (or AIP) has become extremely popular recently as a dietary approach to manage autoimmune disease. I’ve been aware of the AIP for quite some time, but have been pretty turned off of very restrictive diets for the past few years based on my experiences with GAPS/SCD (and for other reasons as well). But after dealing with several back-to-back flare-ups related to recent treatments I’ve been exploring, I decided to give it a shot.

However, I was a little worried about getting enough carbs on the diet. Most common starchy foods (including potatoes and white rice, two of my staples) are on the “no” list, and AIP proponents usually recommend limiting fruit and sweeteners. That leaves sweet potatoes and plantains as the only familiar sources of dense carbohydrate, with things like squash and parsnips providing lesser (but respectable) amounts of non-starchy carbs.

What is a “whole food” diet, really?

Inigo Montoya

I started thinking about this question yesterday (in response to something I’ll share below) and had a bit of a “woah – paradigm shift!” moment, so I thought I’d share with you all! (Also, I didn’t want to pass up an opportunity to have a picture of Inigo Montoya on my blog.)

In the realm of nutrition, the “whole food” diet reigns supreme. From the USDA Dietary Guidelines for Americans to your neighborhood Paleo blogger, almost everyone agrees that a healthy diet is a diet based on “whole foods.”

It’s quite interesting, then, that some of these “whole food” diets have very little in common with each other. It’s even more interesting that some of these “whole food” diets include recommendations to eat things that are definitely not “whole foods.”  [Read more…] about What is a “whole food” diet, really?

5 Reasons You Should Eat Oysters

Alyssa Luck · Aug 3, 2015 · Leave a Comment

Last week, my family and I went on vacation to a beach in Connecticut where my grandparents have a cottage. I had two goals for myself during the trip: 1) to learn how to juggle, and 2) to try raw oysters. I still can’t juggle very well, but I did try raw oysters. And I liked them. And here are 5 reasons you should eat them too. [Read more…] about 5 Reasons You Should Eat Oysters

Is it Possible to be Healthy on a Vegan Diet? [Part Two]

Alyssa Luck · Jul 15, 2013 · Leave a Comment

Note: this is one of my oldest posts, written when I was 19. I’m sure there are FAR better and more comprehensive summaries out there of the nutritional risks of a vegan diet, but this post (along with part one) do cover the high points, so I’ve left them up!

In part one, I discussed whether it’s possible to get enough vitamin D, calcium and vitamin K2 – three nutrients that are vital to bone health – on a vegan diet, without using supplements. We discovered that it is possible, but only if you get lots of sunlight, eat plenty of greens, properly prepare your nuts and seeds, and eat natto. In this post I’ll wrap it up by looking at iron, zinc, vitamin A, and vitamin B12. Then we can finally answer the question: Is it possible to be healthy on a vegan diet without the use of supplements?

Is it Possible to be Healthy on a Vegan Diet? [Part One]

Alyssa Luck · Jul 12, 2013 · 4 Comments

Note: this is one of my oldest posts, written when I was 19. I’m sure there are FAR better and more comprehensive summaries out there of the nutritional risks of a vegan diet, but this post (along with part two) do cover the high points, so I’ve left them up!

In my last post in this series on veganism, I looked at anthropological evidence to establish that as a species in our natural habitats, humans are omnivores, and we thrive on an omnivorous diet. But although we are still humans (most of us, anyways), we don’t quite live in our natural habitats anymore, so what applied to the natives that Weston Price studied doesn’t necessarily apply to us. In a modern-day setting with greater access to a variety of foods, can humans thrive on a vegan diet without needing to supplement? Is it biologically possible for humans to get what they need on a diet devoid of animal products?

In this two-part post, I’ll try to answer that question by looking at some of the nutrients that are hardest to come by on a vegan diet. In part one, we’ll look at three nutrients that are vital to bone health: vitamin D, calcium, and vitamin K2.

Are Humans Herbivores?

Alyssa Luck · Mar 11, 2013 · 7 Comments

Note: this is one of my oldest posts, written when I was 19. While this post is certainly not the “fresh take” on the natural diet of humans that I probably thought it was at the time, it still has solid information, so I decided to leave it up! 

This is part three of my series on veganism. Follow the links to read part one and part two!

One source of disagreement between vegans and meat eaters is the question of what humans are supposed to eat. Many vegans claim humans are herbivores, while meat-eaters assert that humans are omnivores. So what are we, anyways? Herbivores? Carnivores? Omnivores? Most of you probably know the answer to this already, but it doesn’t hurt to look at the evidence. To answer this question, it makes sense to start with what humans eat in their ‘natural habitat,’ when they’re completely undisturbed by modern civilization. As such, this post will look at what traditional hunter-gatherer cultures ate!

Plant-Based Diet or Plant-Based Diet?

Alyssa Luck · Mar 2, 2013 · 3 Comments

Note: this is one of my oldest posts, written when I was 19. It’s pretty dumb, but since it’s part of a “series” and does no harm, I decided to leave it up. Enjoy 😉

This is part two of a series on vegan diets. If you haven’t read part one, you can read it here!

Before diving into the meat main part of this series, I think some clarification is necessary. Not all vegan diets are created equal, and the type of vegan diet in question is going to have a huge impact on every topic I want to discuss: nutrition, sustainability, anthropology, and ethics, to name a few. Other than the fact that all vegan diets are devoid of animal products, they can be as different and varied as the people who choose to eat them. As with anything, it’s a sliding scale, but for my purposes I’ve split them into three main categories. I’ve also tried to give them names that will make it easier for me to reference that particular type in the future (:

Veg*n is Not a Curse Word

Alyssa Luck · Feb 28, 2013 · 10 Comments

Note: this is one of my oldest posts, written when I was 19. Upon re-reading almost a decade later, I’m struck by my extreme naivety – but nevertheless, what I wrote back then does still resonate with me on a certain level. So, if for no other reason than to maintain a time capsule of my internet rants and raves, I decided to leave it up!

Yesterday, Alex Jamieson told the world that she is no longer a vegan. If you don’t know who she is and really don’t care, just bear with me for a minute. Alex is best known from the documentary Super Size Me, where her then-boyfriend Morgan Spurlock ate nothing but McDonalds for 30 days. Alex used a vegan approach to get Morgan’s health back on track after his 30 day McDiet, and she has since been a leading voice for health and nutrition in the vegan community. I would encourage you to read her post, but here’s the gist: Alex discovered that at this point in her life, her body needs some animal products to be healthy. Her post yesterday was the first time she’d publicly announced her decision to incorporate some animal products into her diet.

Why The Dietary Guidelines are Wrong about Cholesterol

Alyssa Luck · Dec 24, 2012 · 7 Comments

This is a research paper that I wrote for my English class this semester. I wanted to share it on this blog because it’s about eggs, cholesterol, and the Dietary Guidelines, three things that definitely impact the ancestral health community! 

Abstracthappy eggs

With rising rates of obesity and diabetes, most Americans feel more pressure than ever to make the right food choices. However, the country’s primary source of nutritional guidance – the Dietary Guidelines for Americans – has been criticized for being misleading, inaccurate, and potentially harmful to public health. In this paper, I present eggs as a ‘case study’ to strengthen the criticisms that others have brought against the Dietary Guidelines. The Guidelines advocate limiting egg consumption because of their high cholesterol content. However, having reviewed the scientific literature on cholesterol and health, I conclude that there is no documented health benefit to limiting dietary cholesterol. Additionally, eggs are an excellent source of choline, a nutrient that is sorely lacking in the diets of most Americans. For these reasons, the Dietary Guidelines should actually encourage egg consumption, rather than limit it.

Hi! I’m Alyssa. I like thunderstorms and cats, hate wearing shoes, and I get really nerdy about gut bacteria. This is me in Bali with a monkey on my shoulder. And this is my blog, where I muse about health-related topics and document my relentless self-guinea pigging (in the realms of gut health and orthodontics, mostly). I created the IBD Index to help people with ulcerative colitis and Crohn’s disease discover their next health breakthrough. If you want to know more about me, click here!
