Les petits fruits rouges comme les fraises, framboises, myrtilles, mûres, canneberges… contiennent une grande quantité d’antioxydants (polyphénols) qui aident à protéger le corps contre les dommages cellulaires. L’acide ellagique – un polyphénol – est tout d’abord un détoxifiant pour les cellules. Il empêche la transformation de plusieurs cancérigènes de l’environnement en substances toxiques pour les cellules et leur fait perdre leur capacité d’action sur l’ADN et ainsi d’induire les mutations pouvant déclencher un cancer.

L’acide ellagique permet également d’empêcher l’angiogenèse (c’est-à-dire la formation de nouveaux vaisseaux sanguins à partir de vaisseaux préexistants permettant aux tumeurs cancéreuses de vivre).

Ce polyphénol se trouve surtout dans les framboises et les fraises. Toutefois, la molécule des framboises est présente à 90% dans les graines, ce qui rend son assimilation par l’organisme difficile. En revanche la molécule est présente quasiment en intégralité dans la pulpe des fraises.

Les cerises quant à elles, contiennent de l’acide glucarique qui a la capacité de détoxifier l’organisme des xénoestrogènes (aussi appelés « perturbateurs endoctriniens » qui sont des polluants présents dans l’environnement).

Symptoms, risk and screening
Are you over 50 years old, or have you been having urinary problems for some time now? This video is for you! Several diseases can affect your prostate, and it’s important to detect them early. Let’s take a closer look. 



What is the prostate

Illustration de l’appareil de l’homme pour un cancer prostate

The prostate is a gland:

  • Located between the bladder and the penis, just in front of the rectum;
  • Formed of 2 lobes which surround the urethra, a canal that runs through the center of the prostate, from the bladder to the penis, letting urine and sperm flow out of the body;
  • The size of a walnut, which grows larger in size in your forties;
  • That has a soft, spongy texture to the touch like a small, ripe plum.

The prostate is made of:

  • Gland cells that secrete liquids for ejaculation;
  • Muscle cells that participate in the evacuation of your sperm during ejaculation;
  • Fiber cells that maintain the structure of the gland.

Around the prostate, we find:

  • The seminal vesicles, glands that produce sperm and that are located on either side of the prostate;
  • The vas deferens, the tube that carries sperm from the testicle to the seminal vesicles;
  • The nerve bundles that control your bladder and erectile function and that are located on either side of your prostate.


Three main zones of the prostate

Peripheral zone

  • The peripheral zone is the largest area of the prostate. It can easily be felt by the doctor during a digital rectal exam (DRE).
  • Most prostate cancers start in the peripheral zone.

Transition zone

  • This is the area located in the middle of the prostate, between the peripheral and central areas. It surrounds your urethra that runs through the prostate.
  • With age, the transitional area increases in size until it becomes the largest portion of your prostate. This is called benign prostatic hyperplasia (BPH) or enlarged prostate.

Central zone

  • It is the part of the prostate that is farthest from the rectum. This is why prostate tumors located in this area can not be felt by the doctor during a digital rectal examination.
  • If the doctor is in doubt, the following information will help decide if additional investigation is necessary:
    • Your PSA level
    • Your age and family history
    • Your ethnic origin


In short

Your fertility and natural fertilization

  • It produces … a prostatic fluid rich in enzymes, proteins and minerals that nourishes and protects your spermatozoa.
  • It makes … a protein (APS) that is used to liquefy your sperm to facilitate the mobility of your spermatozoa.
  • It allows … ejaculation by contracting.
  • It promotes … fertility through its enzymes facilitating the penetration of sperm through the cervix.
  • It is not related to the mechanism of erection. Therefore, the origin of erectile dysfunction lies elsewhere.

Additional details

Exocrine Function

The prostate is made up of thousands of tiny fluid-producing glands. Specifically, the prostate is an exocrine gland. Exocrine glands are so-called because they secrete through ducts to the outside of the body (or into a cavity that communicates with the outside). Sweat glands are another example of an exocrine gland.

The fluid that the prostate gland produces forms part of semen, the fluid that carries sperm during orgasm. This fluid, produced in the prostate, is stored with sperm in the seminal vesicles. When the male climaxes, muscular contractions cause the prostate to secrete this fluid into the urethra, where it is expelled from the body through the penis.

Urine Flow

The prostate wraps itself around the urethra as it passes from the bladder to the penis. Prostatic changes can affect urine flow. Increasing the size of the prostate or muscle tone may impede the flow of urine due to the close anatomical relationship between the urethra and the prostate.

Prostate Specific Antigen (PSA)

The prostate also produces a protein called prostate-specific antigen (PSA). PSA is released with the ejaculatory fluid and can also be traced in the bloodstream. The testing of PSA levels in the blood is used to detect prostate cancer. The level of PSA in the blood is usually measured in nanograms of PSA per milliliter of blood (ng/mL).

A raised PSA level

Usually, a PSA rate of less than 4 nanograms per milliliter of blood is normal, but age should also be taken into consideration as PSA levels gradually increase with age. A rise in PSA concentration may indicate the presence of:

  • An enlarged prostate (benign prostatic hyperplasia)
  • An inflammation or infection of the prostate (prostatitis)
  • A prostate cancer

Your doctor will have you undergo other tests to determine the exact cause of the increase in your PSA.
