Study Notes
Vitamins
- Vitamins are organic compounds crucial for physiological processes and overall health.
- Vitamins are categorized into fat-soluble (A, D, E, K) and water-soluble (B-complex, C).
- Antioxidants, a subgroup of vitamins, protect against oxidative damage, linked to diseases like cancer. Good sources of antioxidants include broccoli, kale, mango, and strawberries.
- Calcium is essential for bone health and muscle function. Adults need approximately 1000 mg daily, increasing for athletes. Sources include dairy, leafy greens, and fortified foods.
- Magnesium is vital for bone health, energy production, muscle function, nerve function, and blood sugar regulation. Good sources include spinach, almonds, and pumpkin seeds.
- Vitamin D aids calcium absorption and plays a role in immune health. Fatty fish, eggs, and milk are good sources.
- Vitamin B12 is crucial for red blood cell formation and nerve health. Vegans and vegetarians may be deficient and should consume sources like animal products including fish, meat, and dairy.
Minerals
- Minerals like iron support oxygen transport and energy metabolism.
- Iron deficiency can cause fatigue and paleness. Good sources of iron include red meat, lentils, and spinach.
Water
- Water comprises about 60% of the human body and is essential for hydration, body temperature regulation, and joint lubrication.
- The recommended daily intake for adults is 8 glasses (approximately 2 liters).
- Water is a key component of blood plasma.
Carbohydrates
- Carbohydrates are categorized as simple and complex.
- Simple carbohydrates (soda, candy, fruit) quickly raise blood sugar.
- Complex carbohydrates (pasta, rice, potatoes) provide sustained energy and contain fiber.
Fiber
- Soluble fiber (oat bran, apples, beans) lowers cholesterol.
- Insoluble fiber (wheat bran, whole grains) aids digestion and reduces colon cancer risk.
- The recommended daily intake is 25g for women and 38g for men.
Fats
- Unsaturated fats (olive oil, avocados, nuts) are heart-healthy.
- Saturated fats (animal products, butter) should be limited to less than 10% of total daily calories.
- Trans fats (processed foods) increase LDL cholesterol and should be avoided.
Proteins
- Proteins are composed of amino acids.
- Essential amino acids must be obtained from food.
- Complete proteins (meat, eggs, dairy, quinoa, soy) contain all nine essential amino acids.
- The recommended daily intake for adults is approximately 0.8 grams per kilogram of body weight.
Eating Disorders
- Anorexia nervosa is characterized by distorted body image and self-imposed starvation.
- Bulimia nervosa involves binge eating followed by purging (vomiting or laxatives).
- Binge eating disorder involves recurrent episodes of eating large quantities of food without purging.
Mental Health and Stress
- Mental health encompasses managing stress, realizing potential, working productively, and contributing to society.
- Stress can be categorized as eustress (positive) and distress (negative).
- The stress response involves the hypothalamus, pituitary, and adrenal glands.
- Chronic stress can negatively impact the immune system, cardiovascular system, and increase the risk of inflammation and high blood pressure.
Sleep
- Adults should aim for 7-9 hours of sleep per night.
- REM (Rapid Eye Movement) sleep is crucial for memory consolidation and dreaming.
- NREM (Non-Rapid Eye Movement) sleep supports physical restoration and growth hormone release.
Alcohol and Caffeine
- Men should limit alcohol consumption to a maximum of 15 alcoholic drinks per week.
- Women should limit alcohol consumption to a maximum of 10 drinks per week.
- Caffeine intake should be limited to 400 mg per day to avoid negative effects.
Seasonal Affective Disorder (SAD)
- SAD is a type of depression triggered by reduced sunlight and affects 1.5% to 9% of the population.
Drug Interactions
- Drug interactions can manifest as synergism, antagonism, or inhibition. They represent situations where multiple medications taken together cause enhanced or diminished, or potentially blocked, effects of each other.
Suicide Prevention
- Suicide rates are higher in men over 45, and mental health support is vital in such cases.
