[NaturalNews] Recent research has scientists concerned that popular dietary recommendations for weight loss may be placing individuals at an increased risk for diabetes-related conditions.
A team from the New Balance Foundation Obesity Prevention Center Boston Children’s Hospital investigated the impacts of the dietary choices of 21 individuals, for three months. The study’s participants were required to drop 10 to 15 percent of their body weight prior to the study, and have their new weight stabilized. For each of the three months, the study’s participants were placed on a different diet. One was low fat, while the others were low glycemic and low carbohydrate, respectively. Each of the diets, despite their preference of calorie sources, provided the necessary 10 to 35 percent of their intake from protein, as is considered healthy.
Less pain, more gain
The low carbohydrate diet made the largest impact on bodily metabolism rates, but it also came with a significant drawback. The diet also resulted in raised cortisol levels, which have been linked to both lost sensitivity to insulin, and cardiovascular disease. Low fat diets, which are often recommended by the American Heart Association, resulted in insulin resistance and a lower energy use. The best response came from when the participants were placed on the low glycemic diet, which doesn’t eliminate whole classes of nutrients, and as a result, both put less of a strain on the body, and is more easily adapted to individual lifestyles.

[NaturalNews] Weary of expensive dental work? Try a few simple home treatments that help strengthen teeth and gums naturally. With the application of specific dietary and herbal recommendations, loose and decaying teeth are fortified and healed. By practicing purposeful oral hygiene with a few basic ingredients, worrisome dental problems can be economically resolved.
Dietary choices for strong teeth
A healthful diet is the first line of attack against gum disease and tooth decay. Minerals such as calcium and silica are vital for repairing and rebuilding tooth structure. The herbs oatstraw, horsetail, and nettle are excellent dietary sources of silica. Vitamin C, D, and K are also important for gum health and tooth strength. Vitamin C helps to support the collagen network of the gums. A deficiency of this vitamin will lead to tender gums that are susceptible to bacteria, leading to periodontal disease and tooth loss. For foods that help to cleanse problem-causing plaque, focus on crunchy choices like celery, romaine lettuce, and seeds. Sesame seeds are especially beneficial for healthy teeth. High in calcium, they help maintain bone around teeth and gums. Soaking, dehydrating, and grinding the seeds further enhances the bioavailability of nutrients. For safe sweeteners that will not promote decay, use stevia and xylitol. Also, limit acid-forming foods such as coffee, chocolate, soda, and meat.

Want to know how to avoid dementia? Just change your diet. Once again, science is substantiating what many of us already know—that diet can prevent disease, and that fruits and vegetables provide a far reaching range of benefits—specifically, that a group of compounds within produce could help protect people from Alzheimer’s disease and related dementia.
How to Avoid Dementia with Food
Dr. Robert Williams of Kings College in London spoke at the British Pharmacological Society’s Summer Meeting a few years ago highlighting the potential benefits of flavonoids found in vegetables, fruits and red wine. The research shows how to avoid dementia and related diseases through simple dietary changes, with these flavonoids being able delay the onset of Alzheimer’s.
He says his own research has countered many previously held beliefs that such antioxidants were broken down by the body before they could have any beneficial effect on the brain. Also, some clinical trials on other antioxidants showed little benefits on dementia symptoms or prevention, further boosting skepticism.
He says, however, that flavonoids don’t only act as antioxidants, but “exert their biological effects through other mechanisms,” according to Phys.org. Limited studies looking at the effects of green tea flavonoids and those found in grapes can potentially reduce brain pathology and even possibly improve cognition.
Dr. Williams’ research has focused on a specific flavonoid, known as epicatechin.
“We have found that epicatechin protects brain cells from damage but through a mechanism unrelated to its antioxidant activity and shown in laboratory tests that it can also reduce some aspects of Alzheimer’s disease pathology…This is interesting because epicatechin and its breakdown products are measurable in the bloodstream of humans for a number of hours after ingestion and it is one of the relatively few flavonoids known to access the brain suggesting it has the potential to be bioactive in humans.”
His research is admittedly limited at this time and Dr. Williams says that further research is needed to better know what specifically is causing the protective effect.
“The challenge now is to identify the single flavonoid or combination of flavonoids that exert the most positive effects and to define the mechanisms of action and optimal quantity required before embarking on clinical trials to treat their effectiveness in dementia.”
Not only is fruit and vegetables consumption the answer for how to avoid dementia, but consuming these foods could also make you more attractive.
This isn’t the only research to suggest that Alzheimer’s and diet could be linked, or at least that diet could have positive effects on the symptoms of dementia.

[NaturalNews] Countless studies have conclusively demonstrated that a Mediterranean diet significantly lowers the risk of developing cardiovascular disease, stroke, diabetes and many forms of dementia. Nutrition scientists explain that the diet provides a very well-rounded mix of macronutrients, vitamins and minerals as well as a healthy dose of monounsaturated fats that help reduce levels of harmful inflammation and maintain systemic antioxidant status. In short, the meat-restricted Mediterranean diet lowers risk from chronic disease and slashes all-cause mortality with a healthful mix of fruits, vegetables, legumes and lean protein sources.
Spanish researchers from the University of Las Palmas have published the result of a study in the European Journal of Clinical Nutrition that shows how the Mediterranean diet with healthy protein sources including fish, olive oil and nuts can improve mental and physical health, as well as overall quality of life. The lead study author, Dr. Patricia Henriquez-Sanchez commented “The progressive aging of the population in developed countries makes it even more interesting to find out those factors that can increase quality of life and the health of the population.”
Mediterranean diet improves physical and mental well-being to advance quality of life
Researchers designed their study to examine the effect of the Mediterranean diet on 11,000 university students over a period of four years. Dietary intake of the participants was recorded at the beginning of the study, and self-perceived quality of life was measured after the four year monitoring period. In order to determine whether the Mediterranean diet was followed, consumption of vegetables, pulses, fruit, nuts, cereals and fish was rated positively. Consumption of excess meat, dairy products and alcohol was negatively valued, as they do not adhere to Mediterranean dietary standards.
The study team determined that those who align closely with the Mediterranean diet score higher on the quality of life questionnaire in terms of physical and mental well-being. Dr. Henriquez-Sanchez concluded “the Mediterranean diet is an important factor associated with better quality of life and can be considered as a healthy food model.” The Mediterranean diet prescribes three basic elements: lean protein sources (fish, lean meat and eggs, preferably organically raised and harvested), fruit and vegetables and unprocessed monounsaturated fats such as olive oil. Furthermore, it must include a daily intake of 1.5 to 2 liters of fresh water.
A wealth of scientific research over the past several years has shown that the Mediterranean diet and lifestyle provides significant benefits for conditions ranging from arthritis, allergies and asthma to Alzheimer’s disease, diabetes and cardiovascular health. Health-minded individuals fully comprehend that vibrant health is realized by avoiding sugar, sweets, cakes, pastries, hydrogenated fats and sweetened beverages. The Mediterranean diet constitutes an important tool to maintain health and attain optimal quality of life.

[NaturalNews] Curcumin, the active anti-inflammatory compound found in the Indian spice tumeric, has gained an impressive reputation in the fight against many deadly forms of cancer. New evidence released in the journal Cancer Research finds that the natural phenol can slow prostate tumor growth by blocking receptors used to propagate cell tissue growth.
Additional research published in the journal PLoS Onee xplains the precise mechanism exerted by curcumin molecules to target the amyloid fibrils associated with the unnatural progression of protein-like plaque tangles that are characteristic in Alzheimer’s disease patients. Adding curry spice to your healthy diet or supplementing daily with a standardized curcumin capsule will help win your individual war against cancerous proliferation and Alzheimer’s dementia.
Prostate cancer is one of the most common forms of the disease, with more than 250,000 diagnoses in the US each year. Any natural compound that targets the proliferation of prostate cancer cells would provide a significant remedy compared with the allopathic methods of radiation, surgery and chemical agents. To conduct the study, researchers subjected prostate cancer cells to hormone deprivation in the presence and absence of curcumin with ‘physiologically attainable’ doses.
Curcumin blocks prostate cell receptors to thwart cancer progression
The researchers found that curcumin blocked two genetic receptors necessary for prostate cancer advancement. These receptors have been shown is past studies to predict cancer incidence and rate of growth of existing tumors. They noted that the spice extract was “a potent inhibitor of both cell cycle and survival in prostate cancer cells.”
The lead study author, Dr. Karen Knudsen and her team found that other cancer cell lines multiply by a similar receptor mechanism and may also be inhibited by the curry compound. She commented that curcumin “also has implications beyond prostate cancer… in other malignancies, like breast cancer. In tumors where these play an important function, curcumin may prove to be a promising therapeutic agent.”
In a separate research body, scientists found that curcumin prolongs life and enhances activity of brain neurons, acting as a neuroprotective shield against Alzheimer’s disease advancement. The research team determined that curcumin acted to prevent the damaging accumulation of amyloid fibrils around the nerve synapse. Amyloid tangles are known to prevent normal electrical and chemical transmissions required to form memories and maintain cognition.
Scientific research models continue to extol the virtues of natural spice and herbal extracts such as curcumin to help prevent and treat many deadly diseases that kill countless millions each year. Incorporate curry spices as part of your healthy diet or include a daily supplement (250 mg to 500 mg standardized curcumin extract) to significantly lower cancer risk and support healthy brain function.
