“…Conversely, unregulated health care providers (HCPs) are not obligated to abide by any standards of practice. Several of these unregulated providers of health and nutrition information have been critiqued by the scientific community for their lack of evidence-based practice and safety concerns including naturopathy, herbalism, healers, homeopathy, Ayurveda, and traditional Chinese medicine [19][20][21][22]. Consumers' risk of obtaining unproven, misleading, and potentially harmful nutrition information and advice is not limited to one-on-one health care services; many individuals look to the internet for food and nutrition information [23].…”

“…MNT can include complementary and alternative medicine (CAM), which often lacks solid research on which to base sound decisions [24], yet it is promoted for the treatment or prevention of serious conditions such as kidney disease, cancer, diabetes, and hypertension [22]. Health and safety concerns of CAM and nutritional supplements have been around for many years; Angell and Kassirer [25] summarized these concerns in The New England Journal of Medicine more than 2 decades ago.…”

Various definitions have been proposed to describe Medical Nutrition Therapy (MNT). Broadly, MNT encompasses the provision of nutrition information and advice aimed to prevent, treat, and/or manage health conditions. In Canada, the provision of such information and advice is unregulated, thus allowing anyone to provide MNT services regardless of their education and training. This inevitably poses risks of harm such as the provision of unsafe and/or ineffective nutrition advice as well as delayed evidence-based treatment. Canadian research has further demonstrated that the general public is unable to properly differentiate between regulated, evidence-based nutrition providers (registered dietitians) and those who are unregulated. Therefore, the public is at risk. To reduce nutrition misinformation and ultimately improve the health and well-being of the public, the objective of this paper is, first, to propose a standardized definition of MNT for use across Canada and, second, to propose province- and territory-specific legislative amendments for the regulation of MNT throughout the country. We also present an opposing perspective to the proposed viewpoint. Ultimately, health care regulation across the country requires an overhaul before we expect that nutrition information and advice communicated to the public may be consistently evidence based.

“…[2] However, lead also finds its use in many other products like pigments, paints, solder, stained glass, lead crystal glassware, ammunition, ceramic glazes, jewelry, toys, cosmetics, and in traditional medicines. [3][4][5][6][7] The use of lead pipes or lead solder for joining pipes is also one of the significant sources of lead in drinking water. [8] Although lead has no biological function in living beings, its indiscriminate use has caused serious public health problems.…”

Design, Synthesis and Application of Chemically Modified Amberlite XAD‐2 for Separation and Preconcentration of Pb(II)

A highly selective, efficient, green analytical method was developed to separate and preconcentrate trace amounts of lead from aqueous samples using gallic acid‐immobilized Amberlite XAD‐2. The method was designed by determining the stability constant of the Pb‐GA complex and plotting the chemical speciation diagram, which indicated strong complexation of Pb(II) with GA (log βPb‐GA=9.50). The species distribution curve for the Pb‐GA complex indicates almost 98 % complexation, forming Pb‐GA as the predominant species. Considering the strong interaction of GA toward the lead, GA was immobilized on the polymeric matrix of Amberlite XAD‐2, and the conditions for the uptake of lead from the aqueous solutions were optimized by both batch and column methods. The sorption capacity and concentration factor of modified Amberlite XAD‐2 for Pb(II) were found to be 4554 μg g−1 and100 respectively. The method was employed for the determination of lead in various wastewater samples. Molecular modeling studies were also performed on GA‐immobilized Amberlite XAD‐2 to determine the active structure of GA on the surface.

Environmental and health risks associated with heavy metal pollution are serious. Human health can be adversely affected by the smallest amount of heavy metals. Modeling spectrum requires the careful selection of variables. Hence, simple variables that have a low level of interference and a high degree of precision are required for fast analysis and online detection. This study used laser-induced breakdown spectroscopy coupled with variable selection and chemometrics to simultaneously analyze heavy metals (Cd, Cu and Pb) in Fritillaria thunbergii. A total of three machine learning algorithms were utilized, including a gradient boosting machine (GBM), partial least squares regression (PLSR) and support vector regression (SVR). Three promising wavelength selection methods were evaluated for comparison, namely, a competitive adaptive reweighted sampling method (CARS), a random frog method (RF), and an uninformative variable elimination method (UVE). Compared to full wavelengths, the selected wavelengths produced excellent results. Overall, RC2, RV2, RP2, RSMEC, RSMEV and RSMEP for the selected variables are as follows: 0.9967, 0.8899, 0.9403, 1.9853 mg kg−1, 11.3934 mg kg−1, 8.5354 mg kg−1; 0.9933, 0.9316, 0.9665, 5.9332 mg kg−1, 18.3779 mg kg−1, 11.9356 mg kg−1; 0.9992, 0.9736, 0.9686, 1.6707 mg kg−1, 10.2323 mg kg−1, 10.1224 mg kg−1 were obtained for Cd Cu and Pb, respectively. Experimental results showed that all three methods could perform variable selection effectively, with GBM-UVE for Cd, SVR-RF for Pb, and GBM-CARS for Cu providing the best results. The results of the study suggest that LIBS coupled with wavelength selection can be used to detect heavy metals rapidly and accurately in Fritillaria by extracting only a few variables that contain useful information and eliminating non-informative variables.
