Food Additives and Food Dyes

Sent by JUDY CHO | May 14, 2022

In a previous newsletter, I mentioned additives used in vaccines. In Carnivore Cure, I shared many additives and ingredients in foods that are banned in other countries but still permitted in the U.S.


STUDY OF THE WEEK — Additives and Food Dyes

There are many food additives that were once permitted in our foods. After enough known health risks, they banned some of these additives. There is no guarantee that a processed food permitted today, won’t end up on these lists in the future.

This is one other reason why all-natural, whole foods are the best foods for optimal health. The less a man artificially tampers with food, the better.

I did extensive research into food dyes but didn’t include most of the content for Carnivore Cure. (You can thank the editor). The way I kept some of the highlights was in these tables.

There is significant research on food dyes and their less-than-ideal health effects on people, especially children. Conventional care and food scientists always talk about the dose that makes the poison.

Well in just 20 years, we went from 6M pounds of food dye to almost 18M. That’s an incredible increase in dosing.

Excerpt from Carnivore Cure:

“…the Food and Drug Administration has acknowledged that Red 3 is a carcinogen. Back in 1984, the acting commissioner of the FDA, Mark Novitch, said that Red 3 “has clearly been shown to induce cancer” in animal studies and was “of greatest public health concern.” On April 2, 1985, the FDA extended the deadline for a decision on food dye safety for the twenty-seventh time. The FDA said it needed more time to make
a decision.51

In 1990, the FDA finally banned some uses of Red 3, including anything applied to the skin, stating that high doses of the color additive can cause cancer in lab animals. But it remained legal to continue to put Red 3 in foods. If you consume Red 3, you have a greater chance of suffering thyroid cancer and chromosomal damage — which even the FDA acknowledged.52

Red 3 remains a legal food additive today. Red 3 is dangerous for our skin but safe to digest?

Annually, food companies use about 200,000 pounds of Red 3 to make such items as Fruit Roll-Ups and Kid Cuisine frozen meals.53

The FDA’s definition of safety for color additives states, as published in the 2019 Code of
Federal Regulations, that “safe means that there is convincing evidence that establishes with reasonable certainty that no harm will result from the intended use of the color additive.”

More concerning is that Americans are now consuming five times more artificial food colorings than in 1955.

In 2005, it was considered reasonable for an American twelve-year-old to consume more than ten pounds of food dye. The certified amount rose from 12 mg per capita per day (0.0002 teaspoons) in 1950 to 62 mg (0.002 tsp) per capita per day in 2010. 54

What changed?

The 2014 study that found this increase is alarming because the amounts of coloring found in a single serving are higher than levels demonstrated in clinical trials to impair children’s behavior.

Researchers estimate that children could easily consume 100 to 200 mg of artificial food coloring daily.” (Source: Carnivore Cure, Chapter 3).




MN Starvation Study. See the last posts for additional context.

🍽Once the men were starved, their desire to prolong their eating times reminds me of One Meal a Day (OMAD).

🙋🏻‍♀️I was OMAD for my first year of carnivore. But I noticed that I was increasing my food consumption slowly.

❤️‍🩹OMAD was a perfect bandaid: it permitted my bingeing habits to continue. I never learned to regulate meals and quantities.

💡If you land on OMAD because you feel best with OMAD, that may be okay.

🩹If you do OMAD because you can’t control yourself eating 2x a day, OMAD is a bandaid.

📚Some research shows that with OMAD and our digestive system, any fasting past 16 hours can affect the digestive system.

🦠Our bodies have less gastric juices and digestive enzymes, and when we eat a 2000–3000 calorie meal after almost 24 hours, it can cause a higher insulin spike and throw off our gut flora.

🧀One tip: don’t break fasts with dairy. Your gut mucosal layer is more sensitive to inflammation. When breaking a fast with dairy, you can have a prostaglandin response, triggering inflammation (BCM-7 & A1 Beta Casein) in the gut.

🤒This can then cause an immune reaction response, breaking down the gut wall and triggering autoimmune-type symptoms.

Back to the study:
Most of the men lost about 25% of their body weight, yet they did not see themselves as underweight. They viewed others as fat.

Some became preoccupied with their abdomen and complained about bloating and other gut discomforts.

It required the participants to initially consume more than 3200 calories to restore their nutrition and weight for their behaviors to then normalize.

💔Some men developed eating disorders (binge-eating). Many of the participants were warned against overeating, but without the caloric restrictions, some of the men began to engage in extreme overeating.

Everyone is susceptible to disordered eating. The perfect storm:
🔻Eating nutrient-poor foods
🔻Over fasting
🔻Overuse of stimulants

⛑This isn’t an easy topic but it’s worth considering for your longevity.

A lot of questions came up after my OMAD post. I want to share some more context as nuance always matters, but is difficult to do in a small social media post.

Some people may be able to do OMAD long-term but for many, it may not be ideal. Read through the list and if it does not apply to you, then don’t worry about changing your way of eating.

I firmly believe in the body’s innate wisdom. If you eat sufficiently in your one meal and your gut feels well, and your symptoms are next to none, I’d keep on, keepin’ on. But that said, here are some of my concerns:

  1. As a root-cause healer, I focus on gut healing and recommend habits that will improve gut function. By eating OMAD, we give our body one chance to obtain, break down, absorb, and assimilate our nutrients. If you don’t eat enough or don’t have enough HCl, bile, or small intestine function, the risk of malabsorption becomes greater.
  2. Most people that eat OMAD tend to undereat. I see this issue more prevalent in women than men. Maybe that’s why women foraged more than men. If undereating is occurring, the first issue of insufficient nutrients becomes a problem.
  3. Weight loss: Dr. Jason Fung says that when his patients do OMAD, their body considers it maintenance eating. OMAD is not a way to lose weight anymore. The better way to lose weight is to trick the metabolism by eating days of two mad, OMAD, more fat, fewer calories, etc. Consistent OMAD becomes a place of maintenance, even if you aren’t at a maintenance weight.
  4. In order to eat enough in one meal and consume enough fat for hormone and thyroid function, the OMAD requires a substantial amount of fat. It’s a considerable amount of fat and most people with a lack of ideal digestion will end up having loose stools. They’ll then end up aiming for lower fat, but this is not ideal for (cholesterol/steroid) hormone functions (including testosterone, DHEA, progesterone, estradiol, etc.)
  5. If you have a poor relationship with food and/or have chronically dieted, you may constantly trigger the body to think it’s starving. When you finally eat, it will open the floodgates and the foraging for all types of foods. (It is critical to know yourself — if this isn’t you, it’s a non-issue.)

After working with hundreds of carnivore clients, I’ve found that most people do not have proper gut function, especially due to our modern-day lifestyles.

Some people say our ancestors ate once a day, but it doesn’t mean much when our ancestors also didn’t have the modern life toxins and stressors that reduce our HCl and gut function (and cause gut permeability).

I always pair my content with evidence-based research, biochemistry, and the stories of my real-life clients. And the truth is that most of my carnivore clients do not eat OMAD (less than 10%.)

If you aren’t sure if OMAD is hurting or helping, you can do your own experiment. Get bloodwork after 3 months of eating OMAD and then get bloodwork after 3 months of two-mad or three-mad. With both experiments, track your sleep, stool, mood, and energy.

Therein lies your personal answer to this OMAD question.

Real talk: My goal isn’t to fear-monger, sensationalize, or be dogmatic. I try to hold a safe space to have the difficult conversations that force us to pause and face the music. My content won’t apply to every single person and that’s absolutely expected. Have a moment of pause, agree to disagree for yourself, and carry on.

I’ve found healing with a meat-only diet, and my advocacy is to get you to optimal health (or as close as possible).

Continuing the giveaway from last week, the first person to respond to this email with what they’ve healed on a meat-based diet will get a package of grass-fed bone broth protein sent their way!
