Study Notes
Nutraceuticals and Disease Prevention
- Nutraceuticals are food-derived products with health benefits beyond basic nutrition; they promote health and prevent disease.
Cardiovascular Health
- Omega-3 fatty acids (fish oil) reduce triglycerides, lower blood pressure, prevent irregular heartbeats (arrhythmias), and lower heart disease risk.
- Antioxidants like vitamin C, vitamin E, and flavonoids reduce oxidative stress and inflammation, thus preventing cardiovascular disease.
Bone Health
- Calcium and vitamin D are crucial for bone health and osteoporosis prevention.
- Isoflavones (in soy products) support bone density, especially in postmenopausal women.
Cancer Prevention
- Curcumin (turmeric) has anti-inflammatory and antioxidant properties, potentially inhibiting cancer cell growth and metastasis.
- Lycopene (tomatoes) neutralizes free radicals, potentially reducing prostate and other cancers.
Digestive Health
- Probiotics (yogurt) promote gut health by maintaining a balanced microbiota, potentially reducing gastrointestinal disorders.
- Prebiotics (non-digestible fibers) feed probiotics, supporting a healthy gut environment and reducing inflammation.
Metabolic Disorders
- Polyphenols (green tea, grapes, berries) improve insulin sensitivity and regulate blood sugar, contributing to type 2 diabetes prevention.
- High-fiber nutraceuticals (whole grains, legumes) promote healthy metabolism and prevent obesity and metabolic syndrome.
Neurological Health
- Ginkgo biloba may enhance cognitive function and help prevent dementia and Alzheimer's disease.
- Omega-3 fatty acids are crucial for brain health and reduce neurodegenerative disease risk.
Drug-Nutrient Interactions
- Warfarin and vitamin K: Warfarin is an anticoagulant; vitamin K intake affects its effectiveness.
- Metformin and vitamin B12: Metformin may reduce vitamin B12 absorption.
- Proton Pump Inhibitors (PPIs) and minerals (magnesium, calcium, vitamin B12): PPIs can decrease mineral absorption leading to deficiencies.
- Antibiotics and gut flora: Antibiotics can disrupt gut microbiota, affecting vitamin synthesis and absorption.
Nutrient Effects on Drug Metabolism
- Grapefruit juice inhibits CYP3A4, increasing certain drug levels and potentially increasing toxicity risk.
- High-fiber diets may reduce drug absorption.
- Calcium and iron supplements can interfere with antibiotic absorption.
Antioxidant Types
- Antioxidants: Any atom/molecule that "steals/accepts" electrons from other molecules.
- Sources: External (smoking, radiation) or internal (cellular respiration).
- Endogenous antioxidants: produced by the body (SOD, CAT, GPx)
- Exogenous antioxidants: obtained from diet/supplements (vitamins, minerals, phytochemicals).
