Cabbage for your guts


Cabbage can provide you with some special cholesterol-lowering benefits if you will cook it by steaming. The fiber-related components in cabbage do a better job of binding together with bile acids in your digestive tract when they’ve been steamed. When this binding process takes place, it’s easier for bile acids to be excreted, and the result is a lowering of your cholesterol levels. Raw cabbage still has cholesterol-lowering ability, just not as much as steamed cabbage.

Researchers now realize that different types of cabbage (red, green, and Savoy) contain different patterns of glucosinolates. This new knowledge means that your broadest health benefits from cabbage are likely to come from inclusion of all varieties in your diet.

Cabbage in general—but also Savoy cabbage in particular—turns out to be an especially good source of sinigrin. Sinigrin is one of the cabbage glucosinolates that has received special attention in cancer prevention research. The sinigrin in cabbage can be converted into allyl-isothiocyanate, or AITC. This isothiocyanate compound has shown unique cancer preventive properties with respect to bladder cancer, colon cancer, and prostate cancer.

In one recent study, short-cooked and raw cabbage were the only types of cabbage to show cancer-preventive benefits—long-cooked cabbage failed to demonstrate measurable benefits.

New research shows that steaming is a better cooking method than microwaving if you want to maximize the health benefits of glucosinolates found in cabbage. That’s because two minutes of microwaving destroys the same amount of myrosinase enzymes as seven minutes of steaming, and you need those myrosinase enzymes to help convert cabbage’s glucosinolates into cancer-preventive compounds.

Mind-altering microbes: Probiotic bacteria may lessen anxiety and depression

Professor John Cryan, Alimentary Pharmabiotic Centre, University College Cork (Credit: Image courtesy of University College Cork) ScienceDaily (Aug. 30, 2011) — Probiotic bacteria have the potential to alter brain neurochemistry and treat anxiety and depression-related disorders according to research published in the Proceedings of the National Academy of Sciences. The research, carried out by Dr Javier Bravo, and Professor John Cryan at the Alimentary Pharmabiotic Centre in University College Cork, along with collaborators from the Brain-Body Institute at McMaster University in Canada, demonstrated that mice fed with Lactobacillus rhamnosus JB-1 showed significantly fewer stress, anxiety and depression-related behaviours than those fed with just broth. Moreover, ingestion of the bacteria resulted in significantly lower levels of the stress-induced hormone, corticosterone. "This study identifies potential brain targets and a pathway through which certain gut organisms can alte

Probiotics Fight Cancer, Colds and Constipation

Image
It may not surprise you to hear that probiotics can reduce constipation (Italy, Amenta et al. 2006). But what may surprise you, is that probiotics play a role in cancer. They have been shown stimulate production of anti-cancer chemicals (Hatakka et al. 2008). The probiotics, Lactobacillus casei, have also been shown in Tokyo to reduce the risk of bladder cancer, depending on frequency and dosage (Ohashi et al. 2002). Numerous probiotics have been shown to fight viruses such as colds, the flu, rotavirus, herpes and ulcers. In New Delhi, 100 children ages 2-5 were given L. acidophilus for 6 months. These children have fewer incidences of colds, flu, diarrhea and fever than the placebo group (Saran et al. 2002). In Japan, Bio E has conducted several studies in hospital in the Philippines & South East Asia that has shown remarkable improvements & shortened days of recovery on children using Bio-15 & Biogenics MD probiotics.

GMO Sweet Corn - Buyers Beware!

Image
Monsanto and the EPA swore that the genetically engineered corn would only harm insects. The Bt-toxin produced inside the plant would be completely destroyed in the human digestive system and would not have any impact at all on consumers, they claimed. Alas, they’ve been proven wrong on that account as well, because not only is Bt corn producing resistant “super-pests,” researchers have also found that the Bt-toxin can indeed wreak havoc on human health. Bt-Toxin Now Found in Many People’s Blood! Last year, doctors at Sherbrooke University Hospital in Quebec found Bt-toxin in the blood of: • 93% of pregnant women tested • 80% of umbilical blood in their babies, and • 67% of non-pregnant women The study authors speculate that the Bt toxin was likely consumed in the normal diet of the Canadian middle class—which makes sense when you consider that genetically engineered corn is present in the vast majority of all processed foods and drinks in the form of high fructose
