3 Foods To Never Eat Again
By Christopher Walker
If you are concerned about consuming excess phytoestrogens, goitrogens (ie. compounds that disrupt your thyroid function), and mineral chelators that cause micronutrient deficiencies, then you may want to take legumes, mint, and nuts out of your diet.
These foods contain compounds that are going directly against the optimal health of your body.
Let’s dive in!
THE BEAN: DO NOT EAT LEGUMES...
Beans of all types contain large amounts of phytoestrogens proven to promote estrogenic activity in the body. They also contain goitrogenic compounds that block iodine and selenium uptake in the thyroid as well as similar amounts of the notorious mineral chelator phytic acid as whole grains.
In this section, I will explore the evidence showing this reality, and by the end of this, you will understand how your body will be so much healthier when you stop eating beans.
What Is “Good Health”
First off, I think it is important to identify what I mean by the word and the idea of “Good Health.” I personally view health in the human body from a systemic view. In doing so, I see the body as one whole system that operates optimally only when two major conditions are met.
- All micronutrient deficiencies are corrected (therefore, anything that causes micronutrient deficiencies would be anti-health)
- The body is hormonally balanced. Meaning the stress hormones (like cortisol, estrogen, prolactin, and SHBG) are low, while protective hormones like all of the reproductive hormones and thyroid hormones are high. The balance of the ratios of stress to protective hormones are absolutely essential for health in the body. (Therefore anything that causes hormonal imbalance and endocrine disruption is considered unhealthy).
If anybody disagrees that the body does not need adequate micronutrient levels to operate properly, or that the body should have higher stress hormones and low reproductive hormones, well, then it is understandable that they would disagree with me. I wish them the best of luck in attempting to live long lives and reproduce.
But if you agree with me, that the body needs sufficient raw material from vitamins and minerals to operate properly without deficiencies, and that it should exist in a state of hormonal balance, then you will naturally follow my logic as to what is healthy for the body, and what is NOT.
Beans Are Not Healthy
Under this definition, Beans are considered a food to avoid.
Let’s take a look at the research:
This study shows that under soy, legumes have the highest phytoestrogen content per 100 grams.
Note - For meat, they are talking about processed meat. Not high quality grass fed organic meat.
This study shows there were four different estrogens present in a flowering bean plant.
This study states these phytoestrogens have a similar molecular structure to that of endocrine disruptors like BPA.
This study shows that legume extracts have high levels of estrogenic activity. “They had significant competitive binding to estrogen receptor Beta (ER-B). Estrogenic activity was determined using an estrogen-dependent MCF-7 breast cancer cell proliferation assay. The extracts displayed increased cell proliferation above levels observed with estradiol. The pure estrogen antagonist, ICI 182,780, suppressed cell proliferation induced by the extracts, suggesting an ER-related signaling pathway was involved. All seven of the extracts exhibited preferential agonist activity toward ER-B.”
This study on tropical legumes shows a significant effect on the impact of birth on multiple species of animals.
This Dissertation looked at different plants and the effects that they have on the reproduction in several animals. Looks largely at the influence of legumes on estrogenic activity (uterine weights).
Legumes produced infertility on female mice.
Uterine enlargement was found when looking at phytoestrogen effect on thyroid.
This study shows the goitrogen effect of tropical legume on grazing animals.
And if all of those endocrine disrupting properties of beans are not bad enough, we also find that beans have some of the highest content of a compound known as phytic acid of any type of food. ›
Phytic acid is a strong chelator of minerals, meaning that it easily binds to many essential minerals. This is helpful within that plant itself, since this is an evolutionary design meant to help the plant store lots of its own minerals.
However, the plant stores its minerals in the indigestible part of the plant or grain as a natural defense mechanism. An example of this is the bran on brown rice, where even during human consumption, the human gut typically cannot actually digest and get access to these stored minerals.
The phytic acid however, poses an issue to the human body since it still chelates minerals in humans when consumed, especially in large amounts. Some researchers have even gone so far as to assert that humans should not consume phytic acid and its consumption in the human body is responsible for the population scale micronutrient deficiencies of nearly every essential vitamin and mineral.
This book “Food Phytates” on page 212 states the fact of the strong chelating effect of phytic acid and shows that it forms insoluble compounds with many essential minerals. The list includes copper, cobalt, magnesium, manganese, zinc, calcium, and iron.
Of course, this would also mean that vegans and vegetarians are vastly more susceptible to wide scale vitamin and mineral deficiencies, due to their high intake of phytic acid containing foods.
In this section, we are looking at a food that can have a negative eﬀect on your androgen levels.
Without further rambling, let’s check out this nasty food that lowers testosterone:
- Mint, Peppermint, Spearmint
Many of the herbs from the “mentha”, or “mint” -family, including spearmint, peppermint, and various other hybrids, are somewhat known of having testosterone reducing eﬀects.
For the sake of clarity, let’s focus on the two most common plants of the mint family; peppermint (Mentha spicata) and spearmint (Mentha piperita).
Both are heavily used for culinary and food manufacturing purposes, though they can also be found in many soaps, shampoos, cough- relievers, lip balms, and toothpaste. Most herbal teas also tend to contain plants or plant extracts from the mint family…
And even though mint-products tend to taste and smell pretty great, their eﬀect on testosterone levels may not be that awesome.
Mint and Testosterone Levels
Much of the research about peppermint and spearmint on male testosterone levels comes from studies using male wistar rats as test subjects.
In a study conducted 11 years ago, 48 rats were divided into 4 groups:
- Group one received commercial drinking water (control).
- Group two received 20g/L peppermint tea.
- Group three got 20g/L spearmint tea.
- Group four got 40g/L spearmint tea.
When compared to the control group, the peppermint tea at 20g/L reduced total testosterone levels by 23%, whereas the spearmint tea at 20g/L reduced total T by a whopping 51%. If you translate this into human dosages, 20g/L is the equivalent of steeping a cup of tea from 5 grams of tea leaves.
A study from 2008 showed that spearmint suppressed testosterone production and acted as an anti-androgen in male rats. The researchers theorized that spearmint works by inducing oxidative stress in hypothalamus, resulting in down-regulation of T synthesis in testicles.
Another rodent study conducted in 2014, found out that at 10-40mg/kg spearmint showed no significant toxic eﬀects on the reproductive system, but still, a trend towards lowered testosterone levels was noted.
What about human studies?
Unfortunately, there are not any trials done on human males.
BUT… Spearmint has been shown to significantly reduce testosterone levels in women.
Much like in the case of flaxseeds (see number #1 above), spearmint has been studied on women with high androgen levels, and who battle with the main cause of that: hirsutism (excessive facial hair growth).
In this study, (418) the researchers gave 21 women subjects a cup of spearmint tea, 2 times a day, for 5 consecutive days. Surprisingly, total testosterone levels did not change much, but the bio-available free-testosterone levels did drop by ~30% on average.
This study was replicated with 42 subjects in 2009, only the duration of the trial was changed to 30 days. The results showed that free and total testosterone levels were significantly reduced over the 30 day period in the women who drank spearmint tea.
Are you a woman battling with hirsutism or a male wistarian rat? Probably not, so this is not direct proof that similar eﬀects would be seen in human males. However, the studies above are still quite heavy evidence towards the fact that the herbs from the mint family and foods containing mint reduce testosterone levels in men.
NUTS ARE UNHEALTHY
If you are concerned about consuming endocrine disrupting substances, rancid toxins, and mineral chelators that cause micronutrient deficiencies, then take nuts out of your diet.
Nuts contain compounds that suppress reproductive hormone production large amounts of the notorious mineral chelator phytic acid, as well as other anti nutrients. The nutritional value of eating certain nuts is next to none, since the metabolize ability has been vastly overestimated.
By the end of this, you will understand how your body will be so much healthier when you stop eating nuts.
Nuts are considered a food to avoid.
Now, let’s dive into this research:
Anti-Nutrient Content of Nuts
Antinutrients as defined by Merriam-Webster are “a naturally-occurring substance (such as saponin or tannin) found in plant-derived foods that interferes with absorption or proper functioning of nutrients in the body.”
Nuts contain 5 different powerful anti-nutrients that inhibit the proper uptake and utilization of a myriad of different micronutrients.
This study shows the anti-nutrient quality of seeds and claims that all seeds are unable to meet any nutritional requirements for animals except for magnesium.
Here is a list of foods that are high in phytic acid with nuts being some of the most prevalent.
This study shows that because of the dense nature of the negative phosphate groups, when consumed it readily attaches to mineral ions rendering them unavailable for uptake by the body.
If the phytic acid content of nuts, and seeds, is not enough to stop eating this “food” then keep reading.
PUFA Content Of Nuts
Polyunsaturated Fatty Acids are fat molecules that contain double carbon bonds in their molecular structure. These double bonds create a very rigid structure, causing these fat molecules to be extremely unstable when exposed to light or heat.
The instability of these fats causes them to break down when exposed to light or heat, especially the relatively high heat of the human body, and they form what are known as free radicals. These free radicals run rampant throughout the body and cause inflammation, especially when they are present in excess.
One of the most radical nutrition and health researchers of our time, Dr. Raymond Peat, talks about the various issues with these fats and the problems that they create on his website here.
From contributing to metastasis to Alzheimer's disease, these fatty acids are extremely toxic and should be avoided as much as humanly possible.
In this table, you can see that nuts have some of the highest pufa content per 200 calorie serving.
This study supports the hypothesis that the higher the PUFA intake (they looked at pufa ratios), the lower the maximum lifespan for mammals was found to be.
This study showed that the polyunsaturates exposed to neural tissue of embryonic chicks during various stages of development could impair neural development.
This study showed that the consumption of PUFA (arachidonic acid, eicosapentaenoic acid) in a dose dependent manner increased the vascular permeability of the vascular system within the brain in rats by increasing free radical damage caused by the breakdown of fatty acids.
Still not convinced that nuts are not suitable for human / mammalian consumption? Let’s take a look at the various toxins that cover nuts.
Nuts and Toxins
The National Library of Medicine had this to say about the toxins that can be found in conjunction with nuts:
“Aflatoxins and fumonisins (FB) are mycotoxins contaminating a large fraction of the world's food, including maize, cereals, groundnuts and tree nuts. Aflatoxins are hepatocarcinogenic (hepato meaning liver, carcinogenic meaning cancerous) in humans, particularly in conjunction with chronic hepatitis B virus infection, and cause aflatoxicosis in episodic poisoning outbreaks.
In animals, these toxins also impair growth and are immunosuppressive; the latter effects are of increasing interest in human populations. FB have been reported to induce liver and kidney tumours in rodents and are classified as Group 2B 'possibly carcinogenic to humans', with ecological studies implying a possible link to increased oesophageal cancer. Recent studies also suggest that the FB may cause neural tube defects in some maize-consuming populations. There is a plausible mechanism for this effect via a disruption of ceramide synthase and sphingolipid biosynthesis.”
I do not know about you but this blows my mind. There are hundreds of studies on this exact subject and many of them come to the exact same conclusion - avoid these toxins as much as possible.
