  • Optimal Foods
    Optimal Foods 1. Almonds: high in monounsaturated and polyunsaturated fats, with 20% of calories coming from protein and dietary fiber. Nutrients include potassium, magnesium, calcium, iron, zinc, vitamin E and an antioxidant flavonoid called amygdlin also known as laetrile. 2. Barley: Like oat bran it is high in beta-glucan fiber which helps to lower cholesterol. Nutrients include copper, magnesium, phosphorous and niacin. 3. Berries : The darker the berry the higher in anti-oxidants. Nutritionally they are an excellent source of flavonoids, especially anthocyanidins, vitamin C and both soluble and insoluble fiber. 4. Brussels Sprouts : Similar to broccoli, and a member of the cabbage family, it contains cancer fighting glucosinolates. Nutritionally it is an excellent source of vitamin C and K, the B vitamins, beta-carotene, potassium and dietary fiber. 5. Carrots: It contains the highest source of proviatamin A carotenes as well as vitamin K, biotin, vitamin C, B6, potassium, thiamine and fiber. 6. Dark Chocolate: It is rich in the flavonoids, similar to those found in berries and apples, that are more easily absorbed than in other foods. It also provides an amino acid called arginine that helps blood vessels to dilate hence regulating blood flow and helping to lower blood pressure. Choose high-quality semisweet dark chocolate with the highest cocoa content that appeals to your taste buds. 7. Dark leafy greens : Kale, arugula, spinach, mustard greens, chard, collards, etc: low calorie, anti-oxidant dense food with carotenes, vitamin C, folic acid, manganese, copper, vitamin E, copper, vitamin B6, potassium, calcium, iron and dietary fiber. Kale is a particularly excellent bioavailable source of calcium while spinach is not.

Lam. – a new rising opportunity for biomedicine. Pharmacia 67(4): 317–323. https://doi.org/10.3897/pharmacia.67. e56112 Abstract Amanita muscaria, commonly known as fly agaric, is a basidiomycete. Its main psychoactive constituents are ibotenic acid and mus- cimol, both involved in ‘pantherina-muscaria’ poisoning syndrome. The rising pharmacological and toxicological interest based on lots of contradictive opinions concerning the use of Amanita muscaria extracts’ neuroprotective role against some neurodegenerative diseases such as Parkinson’s and Alzheimer’s, its potent role in the treatment of cerebral ischaemia and other socially significant health conditions gave the basis for this review. Facts about Amanita muscaria’s morphology, chemical content, toxicological and pharmacological characteristics and usage from ancient times to present-day’s opportunities in modern medicine are presented. Keywords Amanita muscaria, muscimol, ibotenic acid Introduction rica, the genus had an ancestral origin in the Siberian-Be- ringian region in the Tertiary period (Geml et al.

It has been speculated that additional intake of vitamins may reduce the CVD burden by acting on the inflammatory and oxidative response starting from early stages of atherosclerosis, when the vascular impairment might still be reversible or, at least, slowed down. The current review assesses the role of major vitamins on subclinical atherosclerosis process and the potential clinical implications in patients without CVD.

    CENTER FOR DRUG EVALUATION AND RESEARCH APPLICATION NUMBER: 021876Orig1s000 PHARMACOLOGY REVIEW(S) MEMO FOOD AND DRUG ADMINISTRATION Division of Reproductive and Urologic Products Center for Drug Evaluation and Research Date: April 5, 2013 From: Kimberly Hatfield, Ph.D. Toxicologist To: NDA 21876 Subject: Changes to nonclinical scientific bridge and labeling for NDA 21876 (Diclegis) Scientific bridge: NDA 21876 has been submitted as a 505(b)(2) application for the drug product Diclegis (combination of doxylamine succinate and pyridoxine hydrochloride), with nonclinical evidence supporting the safety of Diclegis being based on the Agency’s determination of safety for the Reference Listed Drug (RLD), Bendectin® (NDA 10-598). The nonclinical scientific bridge between Diclegis and the RLD Bendectin® has been revised since submission of the initial nonclinical NDA review. It now states: The bridge for reliance on the nonclinical data generated with Bendectin (10 mg doxylamine succinate and 10 mg pyridoxine hydrochloride) to support the NDA for Diclegis (10 mg doxylamine succinate and 10 mg pyridoxine hydrochloride) is based on: 1) in vivo delayed release, 2) similar pharmacodynamic characteristics, and 3) in vitro dissolution based on Diclectin (a Canadian approved drug product containing 10 mg doxylamine succinate and 10 mg pyridoxine hydrochloride) manufactured at (b) (4) and 4) chemical criteria for doxylamine succinate and pyridoxine hydrochloride defined in the US Pharmacopeia e.g., composition, structure, molecular weight and chemical characteristics. Refer also to the clinical pharmacology memo further elaborating on the scientific bridge submitted by CAPT E. Dennis Bashaw, PharmD. Labeling changes: During label negotiations, a change in Section 13 Carcinogenesis, Mutagenesis and Impairment of Fertility was made.
