Infertility On The Rise In Canada
More Canadians say they're having trouble conceiving, according to new research looking at infertility rates.

Infertility is on the rise in Canada, according to the first study in nearly two decades to measure the proportion of Canadian couples who are having difficulty conceiving.
The researchers didn't set out to discover why the numbers are increasing. But possible explanations range from the growing number of women who are pushing back pregnancy ever later in life, to rising rates of obesity and heavy drinking among women, to declining sperm counts in men — though experts aren't convinced about that final factor.
The use of assisted-procreation technologies has increased dramatically over the past decade, yet "little is known about the prevalence of infertility in the population," the authors write in the journal, Human Reproduction.
The research was supported by funding from Assisted Human Reproduction Canada, a federal agency. The lead author is from Statistics Canada.
According to their estimates, up to 16 per cent of heterosexual couples where the woman is age 18 to 44 are experiencing infertility — a near doubling since the previous time infertility was measured in the nation in 1992.
Not surprisingly, the older the woman, the higher the prevalence of infertility.
Yet infertility appears to be rising among younger women as well, the study finds.
In 1984, about five per cent of couples with a female partner age 18 to 29 were infertile.
By 2009-10, the prevalence for the same age group ranged from seven to 13.7 per cent.
For their analysis, researchers used data from a sample of 4,412 couples from the 2009-2010 Canadian Community Health Survey.
Infertility ranged from 11.5 per cent, to 15.7 per cent.
Those estimates are based on whether couples had reported becoming pregnant or not in the past 12 months, were not using any form of birth control within the past 12 months while having sexual intercourse, and had tried to become pregnant with their current partner. Regardless of how it was defined, each estimate represented an increase in infertility when compared with previous national estimates, said first author Tracey Bushnik, a senior analyst at Statistics Canada.
In 1992, 8.5 per cent of women age 18 to 44 who were married or living common-law were considered infertile.
In 1984, the figure was 5.4 per cent.
Not only are the emotional, physical and financial costs to couples substantial, the researchers write, but the health system also has to bear the costs of caring for premature babies or multiple births born from asssisted reproductive technology.
The new study "just confirms everything we've been gnawing on for the last little while," said Dr. Roger Pierson, a world leader in research into ovarian physiology at the University of Saskatchewan.
Canada's pregnancy specialists have been sounding an alarm over the risks of deferred motherhood. The Society of Obstetricians and Gynaecologists of Canada — which has just issued new guidelines to doctors on "advanced reproductive age" and fertility — worries that women are placing too much blind faith in high-tech fertility treatments to help them conceive once they're ready to have a baby.
For women over 40, the failure rate approaches 90 per cent.
"We're not miracle workers," said Dr. Al Yuzpe, co-author of the new study and co-founder of the Genesis Fertility Centre in Vancouver, one of the largest in-vitro-fertilization clinics in the country.
"We know that there's a precipitous drop in conception rates as women get older," he said.
The other authors of the report were: Jocelynn L. Cook, of the Department of Obstetrics and Gynecology at the University of Ottawa; Suzanne Tough, of the Departments of Pediatrics and Community Health Sciences at the University of Calgary; and John Collins, of the Department of Obstetrics and Gynecology at McMaster University in Hamilton, Ont.
In addition to the well-documented impact of age, other factors affecting female fertility include obesity, alcohol use and sexually transmitted infections.
While fewer women are smoking, more younger women are boozing heavily: reported rates of heavy drinking — defined as five or more drinks at a time at least once a month — among women age 20 to 34 increased from nine per cent in 1994, to 20 per cent in 2010.
Reported rates of chlamydia and gonorrhea are also rising, with the majority of infections reported for women under 30.
And obesity rates are climbing: In 2007-09, 21 per cent of women ages 20 to 39 in Canada were obese, up from four per cent in 1981. Obesity can interfere with a woman's normal ovarian function.
Obese men, meanwhile, have been found to have lower volumes of semen and a higher proportion of abnormal sperm. But just how much a role sperm count deterioration may be having on declining fertility is controversial.
Yuzpe said the data are not convincing.
"The question keeps coming up: Are men's sperm counts getting worse?" he said. "There might be a slight overall reduction in sperm counts, but not from 'normal' to 'abnormal' sort of thing," he said.
Yuzpe said people are much more likely today to report difficulty conceiving than they would have been in the past, "because of the stigma associated with it," but also because people didn't seek help "because there wasn't much we could do for them.
"It's only in the last 35 or 40 years that we've had anything of any significance that we could do for women, or for couples," he said.
Pierson said the study raises important individual and societal questions, including when is the right time to have a child?
"If we were to suddenly stop ART (assisted reproductive technology) and say, 'We're going to support women having children in their early 20s,' I would say that most of the infertility issue would go away.
"That's not our cultural reality," Pierson said. "We have to come to a better understanding of our biological imperatives, and our social expectations."

Health Begins In The Navel!

Eat Meat and Die Early! Any Questions?

Red Meat Consumption Increases Risk of Early Death
Over the years, eating too many burgers, steaks pork chops or other red meat products has been linked to heart disease, diabetes and some cancers. In particular, processed red meat, such as bacon, hot dogs or bologna, has especially strong links to chronic diseases.
But the latest research brings even more dire news for hardcore carnivores. In addition to increasing the odds people will get sick, red meat—whether it is processed or not—can actually increase the risk of premature death overall, according to a study that was published online March 12 in Archives of Internal Medicine.

Researchers, led by An Pan of the Harvard School of Public Health, analyzed health and diet information from more than 121,000 U.S. men and women participating in two long-term health studies. Everyone in the group the researchers assessed had been free of both heart disease and cancer at the outset of the studies.
Over long-term follow-up, as long as 28 years in some cases, more than 13,900 people died—about 9,460 from cancer and almost 6,000 from cardiovascular disease. After adjusting for other factors, the researchers found each daily serving of red meat (beef, pork, lamb or a processed meat, such as bacon, bologna, hot dog, salami or sausage), increased the risk of a premature death by about 12 percent. Processed meat consumption in particular increased these odds even more than did unprocessed meats. And hot dogs and bacon seemed to be the most likely to lead to an early death.
If everyone in the study had limited themselves to 42 grams or less of red meat a day (considered to be about half a standard serving), more than 9,860 early diet-related deaths could have been prevented in the study alone, the researchers estimated.
So if that lamb and ham are off the table, along with all the all-too familiar beef, many people worry that they might not get enough protein with each meal. Fear not, say many health experts, there are plenty of other ways to put protein on your plate that don’t come with such high risks of chronic diseases. Chicken breasts actually have more grams of protein by weight than a piece of beef, and fish isn’t too far behind. The researchers also found that beans, nuts, low-fat dairy and whole grains made for healthful replacements for a red meat meal portion.
And for folks worried about getting enough iron, excess iron from diet has actually been linked to heart attacks and fatal heart disease as well as possibly to cancer, the researchers noted.
Getting to a healthful level of red meat consumption in the U.S. might be an uphill battle. Only about 9.6 percent of the women and 22.8 percent of the men in the studies fell in the low-risk category (of a half-serving-or-less per day) for red-meat consumption.
But contrary to popular thinking, a good diet is as much about what you put in to your mouth as what you omit.
The study found that trading out a serving of red meat for fish or poultry didn’t just negate the red meat risk; rather, it actually improved people’s odds of living longer. Replacing a serving of red meat each day with fish reduced premature mortality risk by 7 percent; for poultry, the reduction was twice that: 14 percent.
Veggies are even better. “Plant-based foods are rich in phytochemicals, bioflavonoids and other substances that are protective,” wrote whole-food diet advocate Dean Ornish in a related essay also published online Monday in Archives of Internal Medicine. “So substituting healthier foods for red meat provides a double benefit to our health.”
Ornish noted that the focus for a healthful diet should be on high-quality over high-quantity: “smaller portions of good foods are more satisfying than larger portions of junk foods.” In addition, he highlights current research-based suggestions for the healthiest diet:
o Little to no red meat; instead obtain protein from poultry, fish, legumes, nuts or other products
o Plenty of good, whole-food carbohydrates, such as whole grains, beans, fruits and vegetables
o Little processed or refined carbohydrates, such as white flower, sugar or corn syrup
o Some good fats, such as omega three fatty acids that are in flax and fish oils
o Little bad fats, such as hydrogenated, saturated or trans fats
Another benefit to cutting red meat consumption: dialing back out-of-control medical costs, Ornish noted. Avoiding chronic diseases linked to excess red meat consumption could decrease medical spending by billions of dollars.

To Alkalize or NOT to Alkalize? I was diagnosed with a large and rare tumour inside my spinal cord (Astrocytoma)
To Alkalize or not To Alkalize?
To me (and Dave), this knowledge has revolutionised our whole way of looking at food and drink , our bodies, our thoughts our actions and our..
PRIORITIES:
It can cost a lot of money to buy water filters, organic foods, supplements, quality juicing and blending appliances, the list goes on.
It does takes A LOT of time daily in the kitchen, washing, chopping, storing, juicing/blending/cooking/generally preparing meals. Everything needs to be planned and organised.
It takes an incredible amount of willpower and discipline to stick with what you believe when that goes against what most people believe, and the temptation to 'indulge' in what is not good for you at all is everywhere, readily available, heavily promoted, and encouraged innocently by friends and family and society in general.
However, this is all offset by the benefits which can take time but nothing worthwhile is easy. Our skin and eyes are noticebly clearer, we feel lighter and more energetic, we feel empowered knowing we can have relative control over our health, rather than feel victimised by that re occuring condition that 'happens' to you.
Touch wood, but I haven't had anything resembling a cold or flu in over a year, and Dave hasn't been sick since last April (in Belgium, where stress, baguets and chocolate were his diet!) We also feel blessed that in this life and in this country we are able to choose to live like this.
I have used his book ‘The pH Miracle’ as a main reference.
The basic premise is that of all the balances the body strive to maintain, the most crucial is the one between acid and alkaline (base). The medical view agrees with this premise but it does not understand how the body turns itself inside out and upside down in order to keep that delicate balance.
Eventually if the acid overload gets too great for the body/blood to handle, these acids will be deposited in various organ systems, including the heart, pancreas, liver and colon or stored in fatty tissues such as breasts, hips, belly and brain.
Chlorophyll- Green vegetables and particularly green leafy veggies are the most nutrient- rich foods on the planet. They provide just about all the vitamins, minerals and micronutrients you could ever need.
Blending (as in making a smoothie in a blender) is also great because you get a lot of fibre that you don’t get when juicing.
| This is what goes into our green juices. You'll have to be munching veggies all day to be able to get the same amount of greens... |
Forget about the no-fat low-fat obsession! Fat plays a crucial role in our bodies and we need healthy fats.
Contrary to what we are led to believe in regards to staying away from salt, salt is essential to our nutrition and body function! Good salt that is, not the processed white poison known as table salt!
(Table salt is bleached and contains additives, preservatives, anti caking agents, fluoride and dextrose)
Good salts help normalize the volume of blood, regulate fluid pressure including blood pressure within cells.
Salt is important in making the heart beat correctly and the regulation of metabolism.
Celtic salt and Himalayan salt are great.
Mineral Salts are also very important. The best is a combination of the 4 most important salts for the body: sodium, potassium bicarbonate and magnesium and calcium carbonate.
Eat plenty of veggies from different varieties, tomatoes, avocadoes, sprouts, herbs & spices, lemons, limes and grapefruits. (Low sugar fruits).
Grains and legumes such as buckwheat, millet, quinoa, spelt, lentils, chickpeas and beans are ok, however make sure they are in the 20-30% acidic part of your diet, as they are slightly acidic.
Nuts are ok except for cashews, peanuts and pistachios (because of their fungal content).
The best nuts to eat are almonds. If you can soak them in water overnight it’s better as it gets rid of their enzyme inhibitors. But other nuts and seeds (such as pine nuts, sunflower kernels, sesame, chia and flex seeds etc) are also not too bad.

La dieta alcalina di Robert Young
La dieta alcalina di Robert Young: un regime basato su assurde teorie, lo scrive Enzo Spisni docente dell'Università di Bologna che critica metodi e contenuti
La dieta alcalina non è una novità per gli italiani, anni fa era apparso un libro che vantava i benefici del sistema, e adesso è in commercio un nuovo volume di oltre 400 pagine che la ripropone in veste rinnovata. La recensione del libro è affidata a Enzo Spisni, docente di Fisiologia della Nutrizione all’Università Bologna, che delinea in modo efficace le assurde teorie dietetiche di un autore un po’ chiacchierato.
La teoria del libro è che tutte le patologie, dal raffreddore al cancro, compreso le malattie cardiovascolari, e quelle infiammatorie croniche, dipendano dall’alterazione del pH (acidità) del nostro corpo, che passa da una alcalinità ritenuta naturale, ad una acidità causata da cattivi alimenti ingeriti. Da un punto di vista scientifico questa teoria risulta alquanto singolare perché sostenere l’esistenza di una dieta universale perfetta e teorizzare che tutte le patologie abbiano una sola causa e una sola cura, non è molto serio.
Il testo contiene alcune affermazioni che meritano di essere commentate. Una delle teorie più affascinanti, degne di un film di fantascienza, è che "i batteri possono mutare in lieviti, i lieviti in funghi ed i funghi in muffe" (par 2.6, pag. 23) e anche che "...i globuli rossi possono modificarsi e rimodificarsi in qualsiasi tipo di cellule di cui il corpo necessita" (par 2.6, pag. 23). Da ciò deriva l'importanza di osservare il sangue in vivo per vedere in una sola goccia "microrganismi cristallizzati, micotossine, colesterolo, metalli, grassi non digeriti e molte altre cose"… Tossine e colesterolo non sono visibili con il microscopio utilizzato dagli autori e per quanto riguarda la presenza di microrganismi nel sangue, è stato dimostrato che ciò accade solo in caso di gravi infezioni o di gravi patologie intestinali, come la malattia di Crohn.
Affermazioni altrettanto false si trovano nella parte dove si svelano i secreti dello stomaco basico (par. 4.1) elaborando una "nuova biologia della salute", che assomiglia ad una fanta-biologia.
Ma veniamo al cuore della trattazione, cioè al modo di mantenere il pH del nostro organismo alcalino, modificando la dieta. Dopo avere suddiviso gli alimenti in due gruppi: acidificanti o alcalinizzanti, cominciano le strane teorie per cui si scopre che: agrumi come limoni, lime e pompelmi sono gli unici frutti classificati come alcalini(!). In pratica si definisce una spremuta di limone una bevanda alcalina. Invece, il riso bianco viene classificato come uno dei cibi più acidi ed acidificanti che esistono. Continuando, i pomodori sono alcalini, il latte e le noci acidi. Chiunque ha minimamente chiaro il concetto di pH e di acidità, dopo avere letto questo libro avrà molte perplessità sull’argomento.
Per quanto riguarda le nozioni sul metabolismo ci sono due concetti che assomigliano molto alle teorie magiche di Mago Merlino.
1) Secondo l’autore la digestione delle proteine animali forma acidi "acido urico, nitrico, solforico e fosforico" mentre questo non accade durante la digestione di quelle vegetali. La teoria è molto singolare ma va dimostrata perché gli aminoacidi sono sostanzialmente gli stessi e ipotizzare un diverso percorso è molto arduo.
2) I carboidrati sono "prodotti di scarto acidi” che “causano la trasformazione biologica delle cellule sane del corpo in batteri e lieviti" (par. 6.2.1, pag. 120).
Quanto alla paranoica accusa verso tutti quei microrganismi, che nel nostro corpo produrrebbero tossine, come i batteri, i lieviti e i funghi per cui si sconsigliano vivamente tutti i cibi fermentati come il vino lo yogurt ed il pane, bisognerebbe ricordare all'autore che molti batteri, tra cui i lactobacilli, producono sostanze come le batteriocine, utilissime all’organismo per difendersi dall’aggressione di altri batteri “cattivi”.
Ultimo concetto descritto riguarda la differenza tra acque buone (alcaline) ed acque cattive (acide). La lunga dissertazione sugli elettroni risulta essere farneticante quanto convincente per i non esperti di chimica e fisica. La conclusione è di usare una macchina molto costosa in grado di alcalinizzare e purificare l'acqua del rubinetto.
Da notare infine che le ricerche citate a sostegno delle teorie dell’autore, mancano di referenze bibliografiche e quindi non si possono consultare in originale.
Da un punto di vista nutrizionale:
Dimenticando per un momento le falsità del libro, una cosa è certa, la dieta alcalina è in pratica una dieta “vegana”, che restringe ulteriormente il gruppo di alimenti perché elimina gran parte della frutta (eccetto limoni, lime e pompelmi) e gran parte dei carboidrati complessi (pasta, riso e cereali). Aderire al progetto alcalino vuol dire nutrirsi quasi esclusivamente di verdura fresca e legumi, esattamente il contrario della dieta ricca e variata che i nutrizionisti suggeriscono! Con la dieta alcalina si perdono sicuramente i chili di troppo, ma nel lungo periodo si possono creare carenze nutrizionali importanti.
