Beer Phytoestrogens

The Most Potent Phytoestrogen is in Beer

Why do alcoholic men develop so-called man boobs and other feminine traits? We know estrogens produce feminization, and our liver clears estrogens from the body. As such, the original theory was that alcohol-induced liver damage led to the retention of excess estrogens. The problem was that when researchers measured estrogen levels, they weren’t elevated. What’s more, even those with cirrhosis of the liver appeared to clear estrogens from the body normally, and men’s testicles started shrinking even before serious liver disease developed.

So, alternative explanations were considered. If it’s not due to estrogens produced endogenously, meaning within the body, maybe alcoholics are being exposed to “exogenous estrogenic substances from dietary sources”—perhaps from phytoestrogens in the plants that alcoholic beverages are made from. The discovery that plants could contain hormonal compounds was made back in 1951 by two Australian chemists charged with finding out the cause of an “epidemic of infertility in sheep that was ravaging their nation’s wool industry.” It took them ten years, but they finally figured out the cause: a compound called genistein, present in a type of clover, and the same phytoestrogen found in soybeans.

You can read about the dreaded clover disease on scare-mongering websites, but you’ll note they never talk about the difference in dose. To get as much as the sheep were getting from clover, you’d have to drink more than 1,000 cartons of soymilk a day or eat more than 8,000 soy burgers or about 800 pounds of tofu a day.

This is not to say you can’t overdo it. There are two case reports in the medical literature that describe feminizing effects associated with eating as few as 14 to 20 servings of soy foods a day. But at reasonable doses, or even considerably higher than the one or two servings a day Asian men eat, soy phytoestrogens do not exert feminizing effects on men.

So, back in 1951, we realized plant compounds could be estrogenic. Two German researchers realized that perhaps that’s why women who handle hops start menstruating, and, indeed, they found estrogenic activity in hops, which is the bittering agent used to make beer. They found trace amounts of the soy phytoestrogens, but in such tiny quantities that beer would not be expected to have an estrogenic effect. In 1999, however, a potent phytoestrogen called 8-prenylnaringenin was discovered in hops, which I discuss in my video The Most Potent Phytoestrogen Is in Beer. In fact, it’s the most potent phytoestrogen found to date, fifty times more potent than the genistein in soy, “provid[ing] an obvious explanation for the menstrual disturbances in female hop workers in the past.” Today, we have machines to pick our hops, so our only exposure is likely via beer consumption, but the levels in beer were found to be so low that they shouldn’t cause any concern.

Then in 2001, a study on a hops-containing “dietary supplement for breast enhancement” raised the concern that another phytoestrogen in hops called isoxanthohumol might be biotransformed by our liver into the more potent 8-PN, which would greatly augment the estrogenic effect of hops. This study was conducted on mice, though. Thankfully, a study using human estrogen receptors found no such liver transformation, so all seemed fine…until 2005. “[T] he liver is not the only transformation site inside the human body.” The human colon contains trillions of microorganisms with enormous metabolic potential. It’s like a whole separate organ within our body, with a hundred livers’ worth of metabolizing power. So, let’s effectively mix some beer with some poop and see what happens.

Indeed, up to a 90 percent conversion was achieved. Up to then, “the concentration of 8-PN in beer was considered too low to affect human health. However, these results show that the activity of the intestinal microbial community could more than 10-fold increase the exposure concentration.” This can explain why you can detect 8-PN in the urine of beer-drinkers for days: Their gut bacteria keep churning it out. Obviously, the amount of straight 8-PN in beer is not the only source of estrogen effects given this conversion. So, a decade ago, the question remained: Might drinking too much beer cause estrogenic effects and feminize men? See my video What Are the Effects of the Hops Phytoestrogen in Beer? for the update.

by Stefan Vogt

ENAD wants to support a local church in their medical missionary efforts and to provide professional help to an already existing mission project.
Haven ́t you ever dreamt about being more practical in our Adventist Mission efforts? We
have! Instead of just talking and discussing about things we could do. Let’s get active!!
For the first time we have the great opportunity to carry out what we have learned and get more practical. In particular – this year we will support Stefan Vogt in his center of influence with medical help and the local church of Liwale in Tanzania by sending teachers to the Bibleschool LIFE (Liwale Institute For Evangelism) who will help in the training of bibleworkers at LIFE.

Why have we chosen Liwale?
The local church of Liwale and Stefan have purposed to reach out to the mostly non-christian community by training lay members to become dedicated evangelists & medical missionaries for their community.  Already planned is the start of the next training course and they are in need of medical professionals and non-medical teachers, both people with passion for mission.

Now it ́s up to YOU! Your choice to get out of the comfort zone! We as the ENAD-Missions-Team and the local church of Liwale need you to get involved in this project, whether you are a professional or not in the medical field, just be passionate! Everyone is warmly welcome!

ENAD MISSION 2019 Honduras

ENAD MISSION 2019 Honduras — 9.05.2019- 23.05.2019 —

Liebe Freunde von ENAD,

Warum führen wir eine ENAD-Missionswoche durchführen? Die Idee von ENAD-Mission ist es, unser Gesundheitswissen anzuwenden und uns mit diesem im Missionsfeld zu engagieren. Das bedeutet, dass ENAD eine örtliche Kirche bei ihren medizinischen Missionsbemühungen unterstützen oder einem bereits bestehenden Missionsprojekt professionelle Hilfe leisten möchte.

Habt ihr noch nie davon geträumt, euer Wissen in die Tat umzusetzen und zu erleben, wie Gott euch in euerem Engagement segnet! Wir haben es erlebt und wollen euch nun die Möglichkeit geben auch so tolle Erfahrungen mit unserem Gott zu machen! Anstatt nur über Dinge zu reden und darüber zu diskutieren, könnten ihr nun aktiv werden! Sei dabei!

WO ? Honduras, Missionscampus VIDA international in El Suyatal bei Cedros


Ein Projekt das von jungen, gottesfürchtigen Leuten auf die Beine gestellt wurde! Der Missionscampus verfügt über eine Grundschule, ein Gesundheitsstation, eine große Gartenanlage mit einer Avocatoplantage und vieles mehr. Ihr könnte euch sowohl medizinisch als auch nicht medizinisch in verschiedensten Bereichen auf dem Missionscampus VIDA mit einbringen.

ENAD MISSION 2019 Honduras


Es besteht eine sehr große Nachfrage nach Zahnreinigung und Zahnbehandlungen. In der Vergangenheit ist immer eine Zahnhygienikerin aus der Schweiz jährlich nach El Suyatal gekommen, und hat sowohl die Kinder, als auch Erwachsene behandelt. Ich werde immer wieder gefragt, wann mal wieder jemand kommen wird. Im Anhang eine Beschreibung von Rene (der Zahnhygienikerin). Es ist eine Maschine vorhanden, mit der man Bohrungen und andere Dinge durchführen kann.

1  Zahnmedizin.

2  Krankengymnastik:

Es gibt nur wenige Krankengymnasten in Honduras. Die Leiterin des Gesundheitszentrums ist ausgebildete Krankengymnastin. Patienten kommen aus einem großen Radius nach El Suyatal, einem Dorf, wo die Schotterstraße endet, um behandelt zu werden. Wenn wir wüssten, dass Kgs mitkommen würden, könnte man das publik machen. Es gibt viel zu tun!

3  Gesundheitsaufklärung:

Abhängig davon, wie viele und wer mitkommen kann, gibt es verschiedene Bedüfnisse:

  • Unterricht für die Kinder in Campos Blancos, der bilingual Grundschule. In einem weiteren Anhang findest du die Themen für die verschiedenen Klassenstufen, die Jenny, die Direktorin der Grundschule zusammengestellt hat. Es wäre eine RIESEN Erleichterung, wenn jemand sich berufen fühlen würde, die vorgegebenen Themen zu unterrichten. Geplant sind 1 Stunde/Tag in einer Woche (also 5 Stunden insgesamt) Gesundheitsaufklärung per Gruppe. Es gibt 3 Gruppen. Das würde also bedeuten, dass 15 Stunden unterrichtet werden müssten.
  • Unterricht für Gesundheitspersonal:
  • Je nachdem, wie viele Teilnehmer mitkommen werden, möchten wir Klassen für Krankenschwestern im Dorf organisieren. Das würde helfen, weitere Kontakte im Dorf zu knüpfen.

4 Ärzte:
Abhängig davon, welche Patienten es gerade im Gesundheitszentrum gibt, könnten sie auch bei den Untersuchungen helfen. Es gibt normalerweise keinen Arzt vor Ort, der das macht.

Nicht medizinisch

5  Lehrtätigkeit:

Die Grundschule braucht immer wieder ‘Lehrer’, die keine ausgebildeten Lehrer sein brauchen, um beim Unterricht auszuhelfen. Voraussetzung: relativ fließend Englisch sprechen. Zumindest so gut, dass man mit den Kindern auf Englisch reden kann.

6  Landwirtschaft:

Abhängig vom Wetter, das auch wie in Europa nicht mehr so ‘vorhersehbar’ ist.

ENAD MISSION 2019 Honduras

  • Normalerweise beginnt im Mai/Juni die Regenzeit. Es ist der Plan, weitere Avocadobäume zu kaufen (als Einnahmequelle für die Zukunft), die dann auf dem Grundstück auf den Bergen gepflanzt werden sollen. Das erfordert viel manuelle Arbeit. Löcher müssen vorbereitet werden, damit die Bäume kurz vor Beginn der Regenzeit eingepflanzt werden können, die dann vom Regen ‘bewässert’ werden. Köperlich anstrengend, aber eine sehr befriedigende Arbeit.
  • Wenn das wegen Regen ausfallen sollte, dann gibt es ausreichend Arbeit direkt dort, wo das Projekt ist. Der Boden muss vorbereitet werden, viel Gemüse gepflanzt etc. Letztendlich entscheiden die Wetterbedingung und die Manpower, was gemacht werden wird. Es besteht auf jeden Fall ein großer Bedarf! ANREISE: Muss selbst organisiert werden! ANSPRECHPERSON: Bei Fragen Zwecks Unterkunft, Verpflegung und Anreise meldet euch bitte baldmöglichst bei Heike! E-mail: Telefon: 017647303538

Effects on Sunlight upon our body

Sunlight has had some bad publicity recently. The impression has been given that even small amounts of sun are harmful. While it is true that excessive sunlight can increase the risk of skin cancer and cataracts, sun in moderate amounts has many benefits.

Life and Health

CC Dawn Ellner on Flickr

Without sunlight, life as we know it could not exist. Fruits and vegetables that receive the direct rays of the sun grow much better than those that are exposed to artificial light. This also applies to humans. Those that do not get a sufficient amount of sunshine experience poorer health. Those who are daily exposed to the vitalizing effect of the sun’s rays have a ruddy complexion and more vibrant health. Sunshine is the most natural and effective antiseptic available to us. Sunshine is also one of the most effective healing agents known.

The sun unlocks the vitamins in food. Without the sun’s rays, we could not get the full value from our food. The sun’s rays gives plants the ability, through a process known as photosynthesis, to take carbon dioxide and oxygen from the air and combine these into the basic food substances by which all things live. This is done by chlorophyll, the green substance in the leaves of the plants. We are unable to duplicate, or even fully understand, this process. Energy from the sun’s rays also act on certain substances in the skin, changing them to vitamin D, one of the essential vitamins to the body.

Sunlight keeps our blood warm and pure and supplies life-giving energy to every organ of our bodies. Our brains are fed by sunshine-enhanced blood; our body is strengthened by the sun’s energy. 

More Benefits of Sunlight

1. Sunlight converts cholesterol into vitamin D, lowering the blood cholesterol. Vitamin D provides a host of advantages to the body, including prevention of many types of cancer and better calcium absorption, which in turn helps prevent osteoporosis and tooth decay, makes stronger denser bones, and speeds bone repair.

2. Sunlight kills many germs and enhances the immune system by increasing gamma globulin, and raising the number and effectiveness of the white blood cells which destroy germs. Lightly tanned skin resists germs and infection much better than untanned skin. Many skin diseases respond well to controlled doses of sunlight. For a clean, fresh bed, expose bedding to sunlight. It’s better to let the sunlight into your homes and risk a little faded furniture than to keep the shades drawn at all times. The health of the occupants is more precious than any expensive furniture.

3. Sunlight soothes the nervous system and is important in treating depression. It gives a sense of well-being by increasing endorphin production in the brain.

4. Sunlight strengthens the cardiovascular system. It improves the circulation, lowers the heart rate, and normalizes the blood pressure and blood sugar.

5. Sunlight aids in digestion and weight loss, increasing the metabolism by stimulating thyroid production.

6. Sunlight improves sleep. Natural light exposure in daytime increases melatonin output at night.

7. The sick are greatly benefited by the sun due to its healing properties. Sunlight enhances waste elimination by improving liver function; it is an effective treatment for jaundice. It relieves the kidneys of some of their burden by eliminating wastes through the skin when you sweat.

Moderate work or exercise outdoors every day will secure these benefits and more. We receive the sun’s rays even on cloudy days; however ordinary window glass filters out 95% of the useful ultraviolet light. 

Doesn’t untraviolet light cause skin cancer?

Sun should be taken in moderation. Over-exposure to sunlight is a major risk factor for skin cancer. Melanoma, a quick spreading skin cancer that is fatal in 20% of cases, is associate with lack of regular sun exposure and repeated burning of the skin. Avoid sunburn, getting your sunshine in small doses. Take great care between 10 am and 3 pm, particularly in summer when the sun is strongest.

Excessive sunshine, especially sunburn, increases your risk of skin cancer. However, sunlight provides so many benefits that avoiding it is not a healthy choice. At least ten minutes of sunlight per day is necessary to maintain good health.
