Study Notes
Vitamins
- Vitamins are organic compounds vital for bodily functions, not providing calories.
- Two types: fat-soluble (A, D, E, K) and water-soluble (B-complex, C).
- Antioxidants (a subgroup of vitamins) protect against cell damage linked to diseases like cancer.
- Good sources include broccoli, kale, mango, and strawberries.
Calcium and Magnesium
- Calcium is crucial for bone and muscle health.
- Daily recommended allowance (RDA) for adults is 1000 mg, increasing for active individuals (1200 mg).
- Sources are dairy, leafy greens, and fortified foods.
- Magnesium is essential for bone health, energy production, muscle/nerve function, and blood sugar regulation.
- Sources include spinach, almonds, and pumpkin seeds.
Vitamin D & B12
- Vitamin D aids calcium absorption and impacts immune function.
- Good sources are fatty fish, eggs, and milk.
- Vitamin B12 is vital for red blood cell formation and nerve health.
- Vegans/vegetarians are at higher risk of deficiency leading to fatigue, depression, and muscle weakness.
- Sources include animal products (fish, meat, dairy).
Minerals
- Minerals like iron support oxygen transport and energy metabolism.
- Iron deficiency leads to fatigue and paleness.
- Good sources include red meat, lentils, and spinach.
Water
- Water comprises 60% of the human body.
- Essential for hydration, temperature regulation, and joint lubrication.
- 8 glasses (2 liters) daily is a general recommendation for adults.
Carbohydrates
- Two types: simple (soda, candy, fruit—quickly raise blood sugar) and complex (pasta, rice, potatoes—sustain energy, contain fiber).
Fiber
- Soluble fiber (oat bran, apples, beans) lowers cholesterol.
- Insoluble fiber (wheat bran, whole grains) aids digestion, reducing colon cancer risk.
- Recommendations range by sex.
Fats
- Unsaturated fats (olive oil, avocados, nuts) are heart-healthy, liquid at room temperature.
- Saturated fats, largely found in animal products (beef, butter), should be limited to below 10% of daily calories.
- Trans fats are found in processed foods and increase LDL cholesterol and should be avoided.
Proteins
- Proteins are composed of amino acids.
- Essential amino acids must be obtained from food (meat, eggs, dairy, certain plant sources).
- Nonessential amino acids are made by the body.
- RDA for protein is ~0.8 grams per kilogram of body weight for average adults.
- Athletes may require more (1.2–1.4 grams/kg).
- Excessive protein intake (>2 grams/kg) is harmful.
Eating Disorders
- Anorexia nervosa: distorted body image, self-imposed starvation, affects 0.5-1% of the population.
- Bulimia nervosa: binge eating followed by purging ("vomiting" or laxatives), affects 1-5% of the population.
- Binge eating disorder: recurring episodes of large food intake without purging; 1% affected.
Mental Health & Stress
- Mental health encompasses managing stress, achieving potential, and contributing to the community.
- Stress is categorized into eustress (positive) and distress (negative).
- The stress response involves the hypothalamus, pituitary, and adrenal glands, potentially impacting the immune system, cardiovascular system, and inflammation risk.
Sleep
- Adults should aim for 7-9 hours of sleep per night.
- Insufficient or excessive sleep can negatively affect health.
- REM (Rapid Eye Movement) sleep is vital for memory and dreaming, while NREM (Non-Rapid Eye Movement) sleep is crucial for physical rest and growth hormone release.
Alcohol and Caffeine
- Alcohol consumption recommendations vary by gender.
- Caffeine should be limited to 400 mg daily to avoid negative side effects like anxiety and sleep issues.
Drug Interactions
- Drug interactions can be synergistic (enhancement), antagonistic (inhibition), or involve other types of effects.
Suicide Prevention
- Suicide rates are higher in some demographics (men, age 45–54).
- Mental health support is vital for those at risk.
