A high intake of yogurt has been found to be associated with a lower risk of developing type 2 diabetes, according to research published in open access journal BMC Medicine. This highlights the importance of having yogurt as part of a healthy diet.
Type 2 diabetes is a chronic condition that occurs when the body doesn’t produce enough insulin, or the body’s cells develop resistance to insulin. Researchers from Harvard School of Public Health pooled the results of three prospective cohort studies that followed the medical history and lifestyle habits of health professionals. They found that high consumption of yogurt was associated with a lower risk of developing type 2 diabetes.
Previous research has suggested calcium, magnesium, or specific fatty acids present in dairy products may lower the risk of type 2 diabetes. It has been shown that probiotic bacteria found in yogurt improves fat profiles and antioxidant status in people with type 2 diabetes and the researchers suggest this could have a risk-lowering effect in developing the condition.
Recently a team of researchers from Vanderbilt University presented their findings that friendly bacteria produce a therapeutic compound in the gut which inhibits weight gain, insulin resistance and other adverse effects of a high-fat diet in mice and that it may be possible to manipulate the bacterial residents of the gut – the gut microbiota — to treat obesity and other chronic diseases.1
In recent research, doctors also found that certain probiotics could help women lose weight and keep it off.
- Women consuming probiotics lost twice as much weight over the 24-week period of the study.2
Bad cholesterol and high glucose levels
Earlier we reported research that says Probiotics are an essentail tool in the fight against bad cholesterol and high glucose levels. Researchers in China have just released an animal study that found that Lactobacillus acidophilus and bifidobacterium can decrease serum levels of lipid and glucose and improve insulin resistance. 3
- Further in another recent study, probiotics are seen as being a positive and therapeutic lifestyle change dietary option in cardiovascular disease as they seem to reduce cholesterol and inflammatory markers.4
In very recent research a bifidobacteria probiotic formulation resulted in a significant reduction of total cholesterol and low-density cholesterol. 5 This confirms and supports the new research and other research which suggested probiotic bacteria (and phytosterols) have shown themselves to be natural cholesterol lowering agents. 6 Other research supports not only Bifidobacterium but Lactobacillus as well.7
Recently this bulletin from the American Heart Association
“Two daily doses of a probiotic lowered key cholesterol-bearing molecules in the blood as well as “bad” and total cholesterol . . . Probiotics are live microorganisms (naturally occurring bacteria in the gut) thought to have beneficial effects; common sources are yogurt or dietary supplements.” 8
How do Probiotics lower cholesterol?
Everyone has cholesterol in their blood, but if the levels of LDL are too high, the excess can accumulate on the walls of the arteries. This build-up of cholesterol and other substances – called plaque – can narrow the artery like a clogged drain. A high level of oxidized cholesterol or a low level of HDL cholesterol can be particularly troublesome. It can also lead to arteriosclerosis, or hardening of the arteries. There are many risks of high cholesterol which range from coronary artery disease to heart attack to stroke.
You need cholesterol
However, we have to keep in mind that cholesterol is a naturally-occurring substance in the body and, at the right level, is necessary as it gives rise to many of the adrenal and sex hormones.
The theory behind probiotics’ ability to lower cholesterol is that the bacteria is able to bind to cholesterol in the small intestine. This binding prevents the cholesterol from being absorbed in the blood stream.
