## Synthesis

**Aldosterone** is an adrenal steroid hormone whose chronic elevation Ray Peat treated as a primary driver of inflammation, fibrosis, and degenerative disease, referring to it increasingly as an *endogenous toxin*. [Source 4, 6] Its canonical role is to retain sodium, but Peat emphasized that it achieves this **at the expense of the increased loss of potassium, magnesium, and probably calcium**, a mineral disruption that directly causes heart rhythm problems by impairing the repolarization of cardiac muscle. [Source 1, 11] Secretion rises nocturnally, and this rise is exaggerated in depressed, stressed, and aging individuals, linking it to the worsening of inflammatory conditions like rheumatoid arthritis and asthma during the night. [Source 1, 10]

The primary physiological trigger for aldosterone synthesis is a perceived deficit of **sodium chloride** or blood volume. Peat argued that low sodium intake, hypothyroidism (which causes sodium loss), low blood sugar, and protein deficiency all signal the kidneys to activate the renin-angiotensin system, increasing aldosterone to retain sodium. [Source 4, 7, 11] This creates a pathological paradox where a sodium-restricted diet activates processes that cause cells to take up sodium inappropriately, leading to intracellular swelling and alkalinity. [Source 10] Georgi Dinkov has noted that this mechanism makes mainstream guidelines for restricting dietary sodium in heart failure nonsensical, as the resulting spike in aldosterone is itself a primary contributor to heart failure. [Source 5] Peat observed that pre-emptive salt loading over several days allows aldosterone to adjust downward, preventing the edema that a sudden dose of salt can cause. [Source 9]

Aldosterone’s pro-inflammatory effects are amplified by a network of other stress mediators. **Serotonin**, **estrogen**, and **cortisol** all increase its secretion, while aldosterone itself promotes the formation of angiotensin II, a potent inflammatory messenger. [Source 3, 6] It inhibits oxidative energy metabolism, increases insulin resistance, and stimulates the production of proinflammatory substances in fat cells. [Source 1, 2] Peat detailed that aldosterone activates the enzyme ornithine decarboxylase (ODC) to produce polyamines that promote cell division, and it raises intracellular pH, both factors that stimulate inappropriate cell proliferation and set the stage for fibrosis. [Source 10] Parathyroid hormone (PTH), which rises on a calcium-deficient diet, further increases aldosterone, creating a link between low calcium intake and hypertension. [Source 7]

The suppression of aldosterone is a hallmark of a high-energy, anti-inflammatory state. Peat explained that the adrenal cortex produces aldosterone first in the shock phase, but as the organism survives with adequate sugar, it shifts toward producing glucocorticoids and finally the protective sex steroids. [Source 6] Once in this healthy state, an abundance of **progesterone** and **testosterone** actively turns off aldosterone production. [Source 6] Nutritional interventions that lower aldosterone include adequate sodium chloride, calcium, and vitamin D, as well as gelatin, which lacks tryptophan and thus limits the formation of serotonin, a major activator of aldosterone synthesis. [Source 4, 7, 10] Sodium bicarbonate can also lower aldosterone by providing sodium and converting to carbon dioxide, which acidifies cells into a protected, oxidized state. [Source 8] Danny Roddy has summarized that aldosterone, alongside adrenaline, cortisol, serotonin, estrogen, prolactin, and PTH, constitutes a core group of adaptive hormones that suppress the metabolic rate and undermine the goal of producing youthful energy. [Source 3]

## People also ask

### How does aldosterone disrupt mineral balance in the body?

Peat emphasized that while aldosterone retains sodium, it does so at the expense of increased loss of potassium, magnesium, and probably calcium, a disruption that can directly cause heart rhythm problems by impairing cardiac muscle repolarization.

### Why might a low-salt diet be harmful according to this view?

The entry describes a paradox where low sodium intake triggers aldosterone secretion to retain sodium, but this causes cells to take up sodium inappropriately, leading to intracellular swelling and alkalinity, and the resulting aldosterone spike is itself a contributor to heart failure.

### What substances or conditions help suppress excess aldosterone?

The corpus states that progesterone and testosterone actively turn off aldosterone production, and nutritional interventions like adequate sodium chloride, calcium, vitamin D, and gelatin can lower it, with gelatin working by limiting the formation of the aldosterone activator serotonin.

> ### Aldosterone
>
> **Danny Roddy:** - Often referred to as the “salt-retaining hormone,” possibly to speed the use of glucose during stress. Aldosterone increases several proinflammatory messengers and inhibits oxidative energy. Carbon Dioxide (CO2) - Produced in the cell and releases oxygen into the tissues. The efficient use of oxygen depends on adequate carbon dioxide. Cell - The smallest unit of life. Cells form tissues, tissues form organs, and organs form us. Chronic stress requires additional cellular energy.

> Yeah You you you probably know dr. Hal Huggins right the mercury fellow Mm-hmm. We used to have Doc. We used to have him on Quite a bit years ago a wonderful guy and he would take all these different blood tests from people and he was a real you know magician at it and he would Thousands of them and he claimed that people that did the pickling and canning sea salt had better He called them blood chemistries had better blood chemistries and people on on sea salt That's the effect of the sodium chloride itself Tom Brewer Cited some studies A book by Shanklin and Hodin gave a lot of the details in which without changing anything else in the diet they gave women with serious eclampsia or preeclampsia symptoms gave them in one case six grams extra sodium chloride per day and in the other I think it was 20 grams extra per day and in both cases that salt alone cured their pregnancy problems has wide very general effects to avoid sodium chloride deficiency you're activating the protective oxidative metabolism suppressing aldosterone and aldosterone rises in proportion to the lack of sodium chloride and aldosterone produces inflammation, heart disease, calcification fibrosis everything bad produced by aldosterone is suppressed when you get enough sodium chloride interesting but do not these different fancier ones you know the Himalayan and what's the other one from over there in Europe Celtic sea salt, don't they have enough sodium chloride to be okay? Very good except they contain heavy metals. Heavy metals, they all do. The discoloration is usually largely from heavy metals oh so the more white ones maybe they would be better? Yeah the pure white that's the thing about pure sea salt and Morton canning salt. Interesting.

> **Danny Roddy:** I want to talk about aldosterone and I think that's actually a mainstream view that angiotensin 2 and aldosterone are involved in heart attacks. And you mentioned how estrogen is bad for the heart and I'm pretty sure estrogen increases aldosterone because of the swelling and the sodiums move from the extracellular tissue into the cell. Is that right?

> **Herb Doctor:** Its amazing how one cell knows how to differentiate into all those different types of cells producing all these hormones.
>
> **Ray Peat:** And it happens that the things that are most stress-producing, like serotonin for example, or shock, will turn on the activity of the glomerulosa layer, that produces the aldosterone. And aldosterone intensifies some of these defensive stress reactions. And the people are now starting to speak of it as an endogenous toxin, as it activates so many of these stress reactions. But serotonin is a major factor in turning it on. But it’s the first thing produced. And as the organism starts surviving, if it can get past that shock stage, with adequate sugar, then the glucocorticoids are produced, and finally, the sex steroids, which aren’t needed if you’re going to be in shock, and starting the death, and so on.

> **Caller:** So many doctors seem to think salt is the worst thing in the world, and especially if you have high blood pressure. I’m a bit overweight, and my blood pressure is high, and I take some medication that controls it. I don’t have side-effects from it. But I’ve always liked salt, and often have a craving for it. I’ve had atrial fibrillation recently, which was related to an over active thyroid, and I’m taking medication for that. The cardiologist said I should practically cut out salt, because he thought it should help me lose weight and bring my blood pressure down, and that the blood pressure could aggravate the atrial fibrillation. I haven’t had any atrial fibrillation attacks since I’ve been treated for the thyroid. But I wonder about the salt thing: medication seems to control my blood pressure. Is there any advantage in cutting back on my salt intake?
>
> **Ray Peat:** The hypothyroidism causes you to lose sodium, and it’s probably the main cause of people having high aldosterone. And once you have high aldosterone, because of low thyroid, or low calcium…
>
> **Caller:** I have hyperthyroid; I had an overactive thyroid, and have been getting it under control.

> ## Calcium and Baking Soda
>
> **Patrick Timpone:** A listener asks: If powdered eggshells are pure calcium carbonate, why not just buy calcium carbonate tablets?
>
> **Ray Peat:** If the manufacturer used oyster shells or eggshells, they would get a pure, safe product. But you can't count on that. When people have analyzed various calcium carbonate products, the eggshell was always the purest.
>
> **Patrick Timpone:** He also says his joint pain subsided by putting a quarter teaspoon of baking soda in his coffee.
>
> **Ray Peat:** It's actually filling in for potential calcium deficiency. The sodium tends to lower your adrenal aldosterone production. Aldosterone is an age-promoting, inflammation-promoting hormone. The bicarbonate is turned into carbon dioxide, acidifying cells and keeping them in the protected, oxidizing state.

> **Ray Peat:** When you take a sudden dose of salt, it makes you swell up and retain water until your aldosterone has adjusted downward. Anything susceptible will swell up—fingers, toes, lips. But people who would get swollen feet on an airplane trip found that if they adjusted two or three days in advance by eating extra salt, they didn't get the swollen feet anymore.

> Estrogen's effects are largely produced by increased tissue hydration. Aldosterone causes cells to take up sodium, while increasing their pH, i.e., raising their alkalinity (Mihailidou and Funder, 2005). Intracellular sodium has long been known to be a factor, along with swelling and alkalinity, in stimulating cell division (Cone and Tongier, 1971). A lack of salt stimulates the formation of serotonin, which in turn stimulates aldosterone synthesis--that is, a sodium restricted diet activates processes that cause cells to take up sodium inappropriately, in a situation reminiscent of the calcium deficient diet causing inappropriate calcification.
>
> Aldosterone, like stress or hypo-osmolarity, activates the enzyme (ODC) which produces the polyamines, that promote cell division, and that can probably account for some of the harmful effects of excessive aldosterone. Eating salty food around bedtime usually has a sleep-inducing effect, and it helps to maintain blood volume (which tends to decrease during the night), and to restrain the nocturnal rise of aldosterone, and other indicators of stress or inflammation. Eating gelatin, which lacks tryptophan, will reduce the formation of serotonin, and is likely to limit the formation of aldosterone. Pregnenolone can sometimes very quickly allow swollen tissues to release their water. This function is probably closely related to its antifibromatogenic function, since swelling and leaking set the stage for fibrosis.

> Hyperosmotic sodium chloride solutions (e.g., 7.5%) are being used more often for treating trauma and shock, because the concentrated solution increases blood volume by removing water from the extravascular spaces, unlike the "isotonic" saline (0.9% sodium chloride), which usually adds to the edema by leaking out of the blood vessels. A 5% sodium chloride solution is effective for promoting healing of damaged corneas, and solutions of 5% to 10% sodium chloride are effective for accelerating the healing of wounds and ulcers. Other hypertonic solutions, for example glucose or urea, have been used therapeutically, but sodium chloride seems to be the most effective in a variety of situations. Thyroid hormone, by maintaining oxidative metabolism with the production of carbon dioxide, is highly protective against excessive water retention and loss of sodium and magnesium.

> Sometimes doctors recommend that constipated people should drink extra water, "to soften the stool."

> ## Aldosterone, Salt, and Thyroid
>
> **Andrew Murray:** You've mentioned aldosterone as being a compound that can be problematic.
>
> **Ray Peat:** Several things start the process toward hypertension, inflammation, and degeneration. Low blood sugar is enough to signal your kidneys to send out renin, starting the process to produce aldosterone. Not eating enough salt also raises aldosterone. If your blood vessels leak—for example, due to hyperventilating—you lose blood volume. Anything that lowers blood volume, sugar, or sodium will cause your kidneys to increase aldosterone. Aldosterone's function is to keep sodium inside your bloodstream to prevent edema and nourish tissues. However, the side effect is that instead of losing sodium, you lose potassium and magnesium. The loss of potassium and magnesium causes heart rhythm problems. The repolarizing process of the heart muscle requires the cell to retain magnesium and potassium and excrete the excitatory sodium and calcium.

> **Sarah Murray:** Is this why women tend to swell premenstrually? With dropping progesterone, they have rising aldosterone?
