Study Notes

Dietary Guidelines and Policies

Purpose: Provide science-based recommendations for promoting health, reducing the risk of chronic diseases, and preventing obesity.
Key Components:
- Balance calories to manage weight.
- Emphasize fruits, vegetables, whole grains, and low-fat dairy.
- Include lean protein sources, such as poultry, fish, nuts, and legumes.
- Limit saturated fats, trans fats, added sugars, and sodium.
MyPlate: A visual guide to help individuals balance their meals with appropriate portions from each food group.
Food Labeling: Policies require nutritional information to help consumers make informed choices about the foods they purchase.
Public Health Initiatives: Implement programs aimed at improving nutritional standards in schools and communities.
Cultural Sensitivity: Recognizes the importance of cultural preferences in dietary practices and food choices.

Functional Foods

Definition: Foods that provide health benefits beyond basic nutrition due to the presence of bioactive compounds.
Categories:
- Probiotics: Live bacteria that promote gut health (e.g., yogurt, kefir).
- Prebiotics: Non-digestible fibers that feed beneficial gut bacteria (e.g., onions, garlic, bananas).
- Fortified Foods: Foods enhanced with additional nutrients (e.g., orange juice fortified with calcium).
- Whole Foods: Foods that are minimally processed and retain their natural nutrients (e.g., fruits, vegetables, whole grains).
Health Benefits: May reduce the risk of chronic diseases, improve digestion, boost immune function, and enhance overall well-being.
Regulatory Considerations: Claims about health benefits must be supported by scientific evidence to ensure consumer safety and reliability.

Dietary Guidelines and Policies

Serve as science-based recommendations to enhance health, mitigate chronic disease risks, and prevent obesity.
Key components prioritize calorie balance for weight management.
Emphasize the consumption of fruits, vegetables, whole grains, and low-fat dairy products.
Include lean protein sources such as poultry, fish, nuts, and legumes in dietary choices.
Recommend limiting intake of saturated and trans fats, added sugars, and sodium.
MyPlate serves as a visual tool aiding individuals to balance meals with proper portion distribution across food groups.
Food labeling policies necessitate nutritional information disclosure, empowering consumers to make informed dietary choices.
Public health initiatives focus on enhancing nutritional standards, especially within schools and community settings.
Acknowledge cultural sensitivity to accommodate diverse dietary practices and preferences.

Functional Foods

Defined as foods offering health benefits beyond basic nutrition due to the presence of bioactive compounds.
Categories include probiotics, which are live bacteria beneficial for gut health (e.g., yogurt, kefir).
Prebiotics are non-digestible fibers that sustain beneficial gut bacteria (found in onions, garlic, bananas).
Fortified foods contain added nutrients (e.g., calcium-enriched orange juice).
Whole foods are minimally processed, preserving natural nutrients (e.g., fresh fruits, vegetables, and whole grains).
Health benefits may encompass reduced chronic disease risk, improved digestion, enhanced immune function, and overall well-being.
Regulatory measures ensure that health benefit claims are scientifically substantiated for consumer safety and trust.

Nutritional Biochemistry

Macronutrients include carbohydrates for energy, proteins for body repair and growth, and lipids for energy storage, insulation, and cellular structure.
Micronutrients are classified into vitamins, which are organic and crucial for metabolic functions like Vitamin C for immune support, and minerals, which are inorganic and vital for functions like Calcium's role in bone health.
Metabolism consists of anabolism, the process of building up molecules like protein synthesis, and catabolism, which involves the breakdown of molecules for energy, exemplified by glycolysis.
Bioavailability refers to how effectively nutrients are absorbed and utilized by the body, influenced by factors like food composition and preparation methods.

Food Preservation Techniques

Refrigeration slows down microbial growth, helping prolong food safety.
Freezing prevents enzyme activity and microbial growth by maintaining low temperatures.
Canning involves heating food to kill microorganisms and sealing it to prevent recontamination.
Dehydration removes moisture from food, thereby inhibiting microbial growth.
Fermentation uses microorganisms to both preserve food and enhance flavor, as seen in products like yogurt.
Chemical preservatives, such as sodium benzoate, are added to food to inhibit spoilage.
Packaging techniques like vacuum sealing and modified atmosphere packaging reduce oxygen exposure, extending shelf life.

Sensory Analysis

The purpose of sensory analysis is to evaluate food products based on human senses including taste, smell, texture, and appearance.
Discriminative testing identifies perceptible differences between products (e.g., triangle test).
Descriptive analysis offers detailed profiles of sensory attributes, including flavor and aroma.
Affective testing measures consumer preferences and acceptance using tools like the hedonic scale.
Key attributes assessed in sensory analysis are flavor, a combination of taste and aroma; texture, which includes mouthfeel and juiciness; and appearance, focusing on color and shape.

Dietary Guidelines and Policies

The purpose of dietary guidelines is to provide science-based recommendations for healthy eating, aiming to enhance public health.
Key recommendations include balancing calorie intake with expenditure and increasing the consumption of fruits, vegetables, whole grains, and lean proteins while limiting added sugars, saturated fats, and sodium.
Dietary policies may involve food labeling regulations that inform consumers and nutritional education campaigns aimed at improving dietary habits.

Functional Foods

Functional foods are defined as those offering health benefits beyond basic nutrition.
Categories of functional foods include probiotics, which are beneficial live microorganisms found in foods like yogurt; fortified foods that have added nutrients, such as fortified cereals; and antioxidant-rich foods that combat oxidative stress, like berries.
Health claims on product packaging must be substantiated by scientific evidence, addressing issues like heart health and immunity support.
