Another reason to add some of the cabbage family to your daily diet, preferably raw is because of their gut healing properties and how they promote gut health through the gut microbiome. The Brassica family including cabbage, broccoli, brussel sprouts, kale, arugula (rocket), bok choy, cauliflower, collard greens, radish, turnip and others have been recognized for their gut healing and gut health properties for hundreds of years and modern epidemiologic studies have shown a frequent consumption of cruciferous vegetables is associated with lower risk of cancer, especially cancers of the digestive tract, bladder, breast, prostate, and lung. However, only now are we recognizing that many of these benefits are mediated through the microbiome and that their frequent consumption alters the composition of the microbiome.
Cruciferous vegetables are a rich source of glucosinolates a precursor to the Isothiocyanates (ITC), which exhibit powerful biological functions in fighting cancers, cardiovascular, neurodegenerative diseases and gut healing. The Isothiocyanates are a by product of specific plant enzymes (myrosinase) active during chewing or crushing when broccoli is consumed raw or lightly steamed, however, like all enzymes myrosinase is deactivated by cooking and ingestion of cooked broccoli typically provides only about one tenth the amount of isothiocyanates as that from raw broccoli. So to maximize the gut healing, gut health and overall benefits of these foods they are best eaten raw or just lightly steamed.
Instead when cooked cruciferous vegetables are consumed, gut bacteria are mainly responsible for ITC production in the gut. This is highlighted after taking oral antibiotics, the ITC’s availability and uptake decreases after eating cooked cruciferous vegetable. It also appears that there is considerable difference in the ability of individuals, due to individual differences in gut microbial community, to produce the isothiocyanates. Although, the gut community’s ability is altered over just 4 days. In one study feeding raw or cooked broccoli for four days or longer both changed the microbiota composition and caused a greater production of isothiocyanates. Interestingly, a three-day withdrawal from broccoli reversed the increased microbial metabolites suggesting that the microbiota requires four or more days of broccoli consumption and is reversible.
The lactic acid bacteria appear to have myrosinase-like activity and the fermented Brassica food products, such as sauerkraut and kimchi, are particularly rich in Lactobacillus, and a diet rich in Brassica may promote Lactobacillus growth in the colon.
Many sleep problems but by far the biggest is sleep deprivation and poor sleep. However too much sleep can also be a problem. Over sleeping may also be a problem. In one study sleeping 10 hours or more also increased the mortality rates by one and a half times.
Sleep is as important to the human body as food and water, but most of us don't get enough sleep. Dysoninia (poor sleep) related sleep disorders alone are broken into Intrinsic, Extrinsic and Circadian‑Rhythm sleep disorders including disorders such as but not limited to: "Psychophysiologic Insomnia, Sleep State Misperception Idiopathic Insomnia, Narcolepsy, Recurrent Hypersomnia, Idiopathic Hypersomnia...Restless Legs Syndrome & Intrinsic Sleep Disorder NOS" (MSM, 2001, pp. 27).
Risk factors for sleep related illness are diet, lifestyle, occupation, stress and grief, amongst many others (Helmanis, 2006 pp. 24‑25).
Almost 90 per cent of Australians suffer from some type sleep disorder at some stage of their lives. Of these, 30 per cent suffer from severe sleep disorders. Very few people regularly enjoy the amount, or quality of sleep that they need. The estimated economic costs to the country from this are between 3 and 7 billion dollars annually. There are also huge, unmeasured physical, psychological, emotional and social costs.
Causative factors for insomnia may be multifaceted but generally include some psycho physiologic hyperarousal or emotional distress. Other precursors may be pain, movement disorders, psychiatric disorders, circadium rhythm dysfunction, medication and substance abuse (Billiard and Bentley, 2004). In some cases, the risk of insomnia is subject to a genetic bias. However, specific physiologic indicators for the familial influence have not been fully identified (Parkes and Lock, 2009).
Insomnia is the difficulty initiating or maintaining sleep or both resulting in inadequate quality or quantity of sleep (Tomoda et al, 2009). Insomnia can manifest itself by many symptoms from not being able to sleep at normal hours and low quality and quantity of sleep to sleeping but not finding it refreshing. Other symptoms may include daytime sleepiness, frequent waking, early morning waking and difficulty retuning to sleep (Cureresearch.com, 2005).
Most adults have experienced insomnia or sleeplessness at one time or another in their lives (Straker, 2008). It is estimated that insomnia effects around 30-50% of the general population with 10% experiencing chronic insomnia (Straker, 2008). It has been estimated that in the US that 70 million people suffer sleep problems, and of these, 30 million suffer chronic insomnia (Stahura and Martin, 2006). Recently a survey showed that 1046 of the 2000 adults surveyed experience at least one night of lost sleep due to insomnia symptoms; the survey also concluded that insomnia is a growing issue of concern (Goolsby, 2006).
Insomnia generally affects women more than men and the incidence rate tends to increase with age (Straker, 2008).
There is a clear correlation of age to insomnia (Curless et a!. 1993). A number of surveys have reported between 28% and 64% of post menopausal women suffer from insomnia (Hachul de Campos et al. 2006).
Insomnia can be classified into three categories transient, short-term and chronic insomnia (Tomoda et al, 2009). Transient insomnia are symptoms lasting less than one week, short term insomnia are symptoms lasting between one-three weeks and chronic insomnia are those symptoms lasting longer than three weeks (Tomoda, 2009).
Narcolepsy is a sleep disorder that causes overwhelming and severe day time sleepiness (Retsas et al, 2000). Pathologic sleepiness is characterised by the fact that it occurs at inappropriate times and places (Retsas et al, 2000). These daytime sleep attacks may occur with or without warning and can occur repeatedly in a single day (Edgar et al, 2006). People who suffer from Narcolepsy often have fragmented night time sleep with frequent brief awakenings (Edgar et al, 2006).
Narcolepsy is typically characterised by the following four symptoms:
Excessive daytime sleepiness (90%)
Cataplexy: A sudden and temporary loss of muscle tone often triggered by emotions such as laughter. (75%)
Hallucinations: Vivid dreamlike experiences that occur while falling asleep or upon wakening. (30%)
Sleep paralysis: Paralysis that occurs most often upon falling asleep or waking up. The person is unable to move for a few minutes. (25%) (Retsas et al, 2000)
Interestingly, regular night time sleep schedule and scheduled naps during the day is required for favourable outcomes (Edgar et al, 2006).
Sleep apnoea affects over 12 million Americans with it being more prevalent in men than women (Sjosten et al, 2009). Sleep apnoea not only deprives sleep from the individual but their partners too (Yip, 2001). Sleep apnoea is defined as frequent and loud snoring and breathing cessation for at least 10 second for five or more episodes per hour followed by awakening abruptly with a loud snort as the blood oxygen level drops (Sjorsten et al, 2009). People with sleep apnoea can experience anywhere between 5 apnoeic episodes per hour to several hundred per night (Sjorsten et al, 2009).
Symptoms of sleep apnoea are:
Excessive daytime sleepiness
Obesity is the major cause of sleep apnoea often losing weight is all that is need to treat this disorder (Yip, 2001).

Estrogens are a group of naturally occurring hormones present in both male testes and female ovaries, with females producing a considerably higher amount. They are particularly influential during puberty, menstruation and pregnancy; however they also assist in regulating the growth of bones, skin, liver and organs of the cardiovascular system. Estrogens, like all hormones, act as chemical signals and are important in helping cells in various organs to sense and respond to changing physiological conditions; therefore the right balance of hormones is critical in order to carry out the functions required of a healthy, strong body. Estrogen binds to a protein, or estrogen receptor, and the estrogen receptor complex can then bind to specific genes and by this, alter the way they are expressed, resulting in a change in cell programming 1.
Environmental estrogens, are now present in everyday products such as polycarbonate plastics, food packaging and cans. However the greatest source for many people is through cosmetics and personal care products and include chemicals such as triclosan, cyclosiloxanes, parabens and phthalates which are often left on the skin to absorb and accumulate 2. Women are disproportionately exposed to many environmental estrogens like paraben and phthalates because they use more personal care products on average than men 3 and teenage girls tend to use even more products than women, averaging 17 different products per day, compared with 12 for women 4.
Since the 1980's, there has been a growing amount of research toward the potential interaction between these environmental estrogens and wild animals, with a number of reports detailing the emergence of 'feminised wildlife’ around the world, and a range of adverse effects in humans including decreased sperm count, increased cases of testicular cancer and testicular abnormalities, increased breast cancer in men and women and premature or precocious puberty. Other adverse health include headache, migraine, depression, gastrointestinal disturbances, insomnia, mastopathia, changes in vaginal bleeding 5. More chronic symptoms affect the cardiovascular system, the skin (itching, rash, abnormal pigmentation), the gallbladder, and tumours, particularly of the breast but also uterus, cervix, vagina and liver 5.
One of the most troubling is their association with breast cancer 6,7,8. Breast cancer is the major cancer affecting women in the Western world 9 and one of the most disturbing and well documented current trends is the alarming increase in breast cancer incidence over the past few decades. Fifty years ago the risk rate was one woman in 20; today it is one in 8 and approximately two-thirds of breast tumors are estrogen receptive, and environmental estrogens like parabens are known to bind to estrogen receptors. Estrogen-dependent cancers, such as breast cancer, are known to be highly responsive to estrogens for growth. Even more disturbing is the increase in numbers of young girls developing breast cancer. Although many factors such as radiation, alcohol, smoking and diet, add to the risk of developing breast cancer, the predominant influencing factor has been identified as the exposure to estrogens throughout an individual's lifetime 9.
The breast is under hormonal control and a fine balance of hormones is what allows the cell to cell communication. Interaction between these cells and the surrounding fluid of the breast tissue is what controls differentiation and growth of the breast 9. If there is a disruption of those hormones, i.e. through the use of synthetic chemicals, the balance of hormonal control is thrown and the cells do not function normally which may lead to breast cancer. In support of this clinical studies show that estrogen has the capacity to drive breast tumours to grow in laboratory studies. Animal experimental studies have also shown the role of estrogen on the growth of breast cancer cells 9. While chemicals which mimic estrogen have been shown to promote and stimulate the proliferation of breast cancer cells 2,10,11, and activate other processes involved in breast cancer 2,11,12. Recent studies have also shown other factors can dramatically increase the the toxicity of Xenoestrogens and studies of individual estrogens may seriously underestimate their growth and spreading effects in breast tissue cells and their potency to promote breast cancer, particularly at lower doses 13.
Although the vast majority of studies on breast cancer are aimed towards women, men can also suffer from the disease, indicating that they have similar risk factors, with one case in a hundred diagnosed breast cancers being a male 14. Although this number is relatively small, the rate of incidence has increased by 25% in 25 years.
Sperm count of the average male in the US or Europe has been found to be declining continuously over the past four decades, dierectly linked with environmental estrogen exposure, and today it is less than 50% of what it was forty years ago15,16. One result of this lower count is the increased rate of male infertility; which is also the single most common cause of infertility. The rate of infertility has quadrupled in the past forty years, from 4% in 1965 to at least 16% today 15.
Other conditions including undescended testes caused by prenatal estrogen exposure to environmental estrogens have also been found in studies on mice and it has been suggested undescended testes increases the rate of testicular cancer 17. The incidence of testicular cancer, namely affecting males between the ages of 20 to 30, has also seen an increase worldwide. Studies have found strong links with exposure to excessive levels of estrogen with hypospadias (abnormal congenital opening of male urethra upon under surface of the penis) 18,19, lower libido 19, congenital anomalies, cryptorchidism and testicular cancer 20,21,22.
Environmental estrogens have also been linked to early puberty in girls and increasing number of girls experiencing precocious puberty in recent years 15. A study in the United States of 17, 000 girls indicated that 7% of white and 27% of black girls exhibited physical signs of puberty by age seven, and for girls aged 10 the percentages increased to 68 and 95 respectively 16. This trend for earlier puberty has been found to be widespread, with similar cases found in the United Kingdom, Canada and New Zealand (Trankina, M. V L., 2001).
Environmental estrogens are also suspected of disrupting thyroid functioning, sexual differentiation of the brain in foetal development and cognitive motor function 23. It is also believed that high levels of environmental estrogen exposure results in lower birth weights, smaller head circumferences, poorer neuromuscular maturity and visual recognition, delays in psychomotor development, short term memory problems, and growth retardation in newborn babies 24.
Prenatal exposure to environmental estrogens also poses a serious health risks to developing fetus and children as evidence of adverse effect on birth outcomes, childhood obesity, and intellectual disability are increasing 25. The placental barrier has been shown to allow these chemicals to cross as many of them have been measured in human fetal cord blood and tissue. More importantly, because organogenesis begins at the time when the fetus is solely dependent on maternal supply, early life exposure to environmental estrogens may lead to adverse short or long term health outcomes due to fetal reprogramming 26.
From testing on animals it has further been proposed that excessive estrogen levels could cause anxious behaviour 27,28, altered fecundency 29, reduced penis size 30 and increased embryo mortality 24. Environmental estrogens are not only capable of binding to estrogen receptors on cell membranes but are also able to bind to neurotransmitters such as epinephrine, neuroepinophrine and dopamine enabling estrogens to influence the body's central nervous system (CNS) 31. Environmental estrogens have also been shown to effect the body’s immune system 30. A large number of studies have also environmental estrogens to contributing to obesity and diabetes, independent of poor diet and physical inactivity; such chemicals including ingredients found in personal care products and cosmetics such as phthalates and phenols 32,33.
More recently studies have found effects of direct exposure to products instead of just individual chemicals. Extensive observational studies have indicated a relationship between certain hair product use and hormonally imbalances including early menache (puberty) 34,35 and uterine fibroids 36 as well as enlargement of breast tissue in boys and men 37.
However, estrogenic (or anti-estrogenic) effects of the personal care products as commercial mixtures have rarely ever been evaluated. In a study of eight commonly used hair and skin products four of the eight personal care products tested (Oil Hair Lotion, Extra-dry Skin Lotion, Intensive Skin Lotion and Petroleum Jelly demonstrated detectable estrogenic activity 38. The estrogenic activity of these products was not predictable by examining their listed ingredients. However, perhaps the most surprising finding about any one product was the estrogenic activity of SP4 (Petroleum Jelly). Petroleum jelly products are also often used on infants as low-cost therapies for common problems such as diaper rash and is manufactured by refinement of the crude petroleum product. While other studies have shown that hair oil use as a child was significantly associated with earlier menarche and hair relaxer use and uterine fibroids among participants in the 36. A third study found an elevated incidence of endometriosis and use of personal care products containing benzophenone-type UV filters 39.
Fortunately, studies have also shown it is relatively easy to reduce exposure by reducing personal care use or using safer products. In one study of around 100 girls they replaced their personal care products with safer alternatives for 3 days. The replacement products were chosen on the basis of whether their ingredient lists included triclosan, benzophenone-3, or parabens. Phthalates are not listed on ingredient lists, but they are often found in scented products. So the researchers avoided products that listed “fragrance” as an ingredient unless they were specifically labeled as phthalate free. More than 90% of the participants had detectible levels of phthalates, parabens, and benzophenone-3 before they started using the replacement products. After using the alternative products for 3 days urinary concentrations of methyl and propyl paraben decreased by 43.9% and 45.4%, respectively, mono-ethyl phthalate decreased by 27.4%, and triclosan decreased by 35.7%. However, there were increases in concentrations of butyl and ethyl paraben, which were detected in about half the girls. These chemicals might have been unintentional contaminants or unlabeled ingredients in replacement products, which they acknowledge they were unable to ensure were paraben free 40.

Men eat 57% more meat, more starchy-vegetables and less green vegetables than women. According to the U.S. National Health and Nutrition Examination Survey there is a big gender gap for eating habits. It appears meat is seen as more “manly”. Other misconceptions are plant based diets don’t have taste and of course the old one that they don’t have enough protein. While there are many misconceptions over meat and protein USA males consume about twice as much protein as they need to. There are also many top male athletes, sportsmen and bodybuilders who are vegetarian or vegan showing that the manly myth of meat just does not hold.
Interestingly while meat is associated with a number of health issues including prostate problems and cancer the lack of green vegetables and nutrient dense plant based foods is the major cause of high blood pressure and the associated erectile dysfunction. Erectile function is probably the most important personal display of manhood. So much for meat being a mans food. In fact to be manly you need to consume more vegetables just like mum used to tell us.
