Abstract (provisional)

Background
The ability of an intermittent fasting (IF)-calorie restriction (CR) regimen (with or without liquid meals) to modulate adipokines in a way that is protective against coronary heart disease (CHD) has yet to be tested.

Objective
Accordingly, we examined the effects of an IFCR diet on adipokine profile, body composition, and markers of CHD risk in obese women.

Methods
Subjects (n = 54) were randomized to either the IFCR-liquid (IFCR-L) or IFCR-food based (IFCR-F) diet for 10 weeks.

Results
Greater decreases in body weight and waist circumference were noted in the IFCR-L group (4 +/- 1 kg; 6 +/- 1 cm) versus the IFCR-F group (3 +/- 1 kg; 4 +/- 1 cm). Similar reductions (P < 0.0001) in fat mass were demonstrated in the IFCR-L (3 +/- 1 kg) and IFCR-F group (2 +/- 1 kg). Reductions in total and LDL cholesterol levels were greater (P = 0.04) in the IFCR-L (19 +/- 10%; 20 +/- 9%, respectively) versus the IFCR-F group (8 +/- 3%; 7 +/- 4%, respectively). LDL peak particle size increased (P < 0.01) in the IFCR-L group only. The proportion of small LDL particles decreased (P < 0.01) in both groups. Adipokines, such as leptin, interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and insulin-like growth factor-1 (IGF-1) decreased (P < 0.05), in the IFCR-L group only.

Conclusion
These findings suggest that IFCR with a liquid diet favorably modulates visceral fat and adipokines in a way that may confer protection against CHD.

How Turmeric Can Save the Aging Brain From Dementia and Premature Death

How Turmeric Can Save the Aging Brain From Dementia and Premature Death

A promising new study published in Cellular Physiology and Biochemistry reveals the primary polyphenol in turmeric known as curcumin (which gives it its golden hue) may provide what the study authors describe as an “effective therapeutic strategy to reverse age-related cerebrovascular dysfunction.”

Age-related cerebrovascular dysfunction is occurring on an epidemic scale in Western countries and include, “stroke, cerebral amyloid angiopathy, cognitive decline and neurodegenerative diseases.” Presently, very few if any conventional medical interventions are capable of providing effective solutions, and none have been found to reverse underlying pathologies in conditions whose trajectories are generally characterized as ‘incurable.’ All the more reason why the new study holds so much promise in providing an evidence-based natural solution that is safe, effective, affordable and easily accessible as a familiar food ingredient.

Aged Garlic and Other Natural Strategies Reduce Hypertension

Aged Garlic and Other Natural Strategies Reduce Hypertension

Researchers from Australia’s University of Adelaide have confirmed that garlic is effective for reducing blood pressure. We can now add garlic to the list of several natural strategies to reduce hypertension. The researchers conducted a double-blind placebo-controlled clinical trial with 79 patients who had been diagnosed with uncontrolled systolic hypertension. Researchers said their trial suggests aged garlic extract to be an effective and tolerable treatment in uncontrolled hypertension, and may be considered as a safe adjunct treatment to conventional antihypertensive therapy.

The Spice That Prevents Fluoride From Destroying Your Brain

The Spice That Prevents Fluoride From Destroying Your Brain

Fluoride is found everywhere today, from antibiotics to drinking water, non stick pans to toothpaste, making exposure inevitable. All the more reason why new research proving this common spice can prevent fluoride damage is so promising.

Fluoride’s neurotoxicity has been the subject of academic debate for decades, and now a matter of increasingly impassioned controversy among the general public as well. A new study published in the Pharmacognosy Magazine, adds experimental support to the suspicion that fluoride is indeed a brain-damaging substance, also revealing that a curcumin (found in turmeric) helps protect against the various health effects associated with fluoride exposure.

Study: Mixed Vitamin E Forms Slow Cognition Decline and Alzheimer’s Disease

Study: Mixed Vitamin E Forms Slow Cognition Decline and Alzheimer’s Disease

This research reported by Case Adams shows how there are multiple forms of vitamin E in nature, and that mixed forms of vitamin E as found in food have tremendous health benefits. Most vitamin E supplements in pill form are simply encapsulated soybean oil, containing mainly just one form of the tocopherol. Soybeans are also over 90% GMO.

In addition to the various forms of tocopherols that are classified as vitamin E, there are also tocotrienols which are generally not found in supplements, but in food. The following chart shows how red palm oil (not the processed version) is nature’s richest source of tocotrienols and vitamin E.

Much like coconut oil, palm oil has been vilified because of its high saturated fat content, although recent meta-studies have been published disproving that saturated fats have any impact on heart disease at all.

Unfortunately, palm oil also gets vilified for ecological reasons where it has been reported to destroy natural habitat on the island of Sumatra in Malaysia and Indonesia. However, palm oil is an introduced crop in Southeast Asia where large scale plantations exist, but in areas where it is native, most of the production is by small-scale sustainable operations, particularly in Africa. Hence, if you are purchasing virgin red palm oil from one of those areas, not only are you purchasing a healthy and sustainable product, but you are also helping to provide jobs for people in some of the poorest areas of the world in Africa.

As Case Adams reports here, these mixed forms of vitamin E with their super high levels of antioxidants have been shown to slow cognition decline and Alzheimer’s Disease.

Immediate Ban on Dental Mercury Amalgam in Philippines Pushed

Immediate Ban on Dental Mercury Amalgam in Philippines Pushed

The mercury used by dentists to manufacture dental amalgam is shipped as a hazardous material to the dental office. Any amalgam leftover is also treated as hazardous waste and requires special precautions to dispose of, yet it’s supposed to be “safe” to keep it in your mouth for years to come.

Sadly, many live with toxic reactions for extended periods of time, never connecting the dots between their failing health and the mercury in their teeth and their environment.
