Key Terms to Review (20)
Bioactive compounds: Bioactive compounds are natural or synthetic substances that have an effect on living organisms, tissues, or cells. These compounds are often found in foods and are believed to contribute to health benefits, influencing processes like inflammation, immunity, and metabolism. Emerging research is increasingly focused on their potential role in disease prevention and health promotion.
Chrononutrition: Chrononutrition refers to the study of how the timing of food intake influences metabolism, health, and overall well-being. This concept suggests that not only what we eat but also when we eat can have significant effects on our body’s biological rhythms, such as circadian rhythms, and subsequently impact factors like weight management, metabolic disorders, and dietary habits.
Dietary Guidelines: Dietary guidelines are science-based recommendations that provide guidance on healthy eating patterns and nutritional practices aimed at promoting overall health and reducing the risk of chronic diseases. They serve as a foundation for public health initiatives, informing individuals and communities about making informed food choices and fostering a healthier lifestyle.
Epigenetic Factors: Epigenetic factors are changes in gene expression or cellular phenotype that do not involve alterations to the underlying DNA sequence. These factors can be influenced by various environmental factors, including nutrition, which can lead to modifications in how genes are turned on or off, ultimately impacting health and disease outcomes.
Functional Foods: Functional foods are foods that offer health benefits beyond basic nutrition, often containing bioactive compounds that can promote health or reduce the risk of disease. These foods are gaining attention due to their potential roles in preventing chronic diseases and improving overall wellness, reflecting a shift towards a more proactive approach to health through diet. They can include whole foods like fruits and vegetables, as well as fortified foods and dietary supplements that provide specific health benefits.
Gut microbiome: The gut microbiome refers to the diverse community of microorganisms, including bacteria, viruses, fungi, and other microbes, that reside in the gastrointestinal tract. This microbial ecosystem plays a crucial role in digestion, metabolism, and overall health, influencing not just gut health but also impacting the immune system and even mental health.
Gut-brain axis: The gut-brain axis is the bidirectional communication network linking the gastrointestinal system and the central nervous system. This complex connection highlights how gut health can influence mental health, behavior, and cognitive functions, underscoring the importance of nutrition in overall well-being.
Intermittent fasting: Intermittent fasting is an eating pattern that alternates between periods of fasting and eating, focusing on when to eat rather than what to eat. This approach has gained popularity as a potential strategy for weight management and overall health improvement, leading to various trends and emerging research on its effectiveness. By allowing the body to have extended breaks from food intake, intermittent fasting may influence metabolic processes and support weight loss efforts.
Microbiome manipulation: Microbiome manipulation refers to the intentional alteration of the composition and activity of the microorganisms living in and on our bodies, particularly in relation to health and nutrition. This can involve dietary changes, the use of probiotics, prebiotics, or even specific medications to influence gut bacteria. Understanding microbiome manipulation opens up exciting possibilities for improving health outcomes, influencing metabolism, and preventing disease through nutritional strategies.
Nutrient Delivery Systems: Nutrient delivery systems refer to various methods and technologies used to transport and distribute nutrients effectively to target cells or tissues in the body. These systems are essential for enhancing the bioavailability and efficacy of nutrients, thereby playing a critical role in nutrition science and therapeutic interventions.
Nutrient-gene interactions: Nutrient-gene interactions refer to the complex relationships between nutrients in our diet and the expression of our genes. This interplay can influence various physiological processes, impacting health and disease states. Understanding these interactions helps researchers identify how specific dietary components may modulate gene expression and contribute to personalized nutrition strategies.
Nutrigenomics: Nutrigenomics is the study of how individual genetic variations affect the body's response to specific nutrients and dietary patterns. This field aims to understand the interaction between genetics and nutrition, ultimately leading to personalized dietary recommendations based on one's genetic makeup. By exploring these relationships, nutrigenomics seeks to improve health outcomes and prevent chronic diseases through tailored nutritional strategies.
Omega-3 fatty acids: Omega-3 fatty acids are essential polyunsaturated fats that play a vital role in human health, primarily found in fish, flaxseeds, and walnuts. These fats are crucial for brain function, inflammation reduction, and cardiovascular health, making them increasingly important in discussions about dietary choices and public health trends.
Personalized nutrition: Personalized nutrition is an approach that tailors dietary recommendations and interventions based on individual characteristics, such as genetics, lifestyle, and health status. This concept emphasizes the idea that one-size-fits-all dietary guidelines may not be effective for everyone, as individual responses to nutrients can vary significantly. By utilizing genetic information and other personal data, personalized nutrition aims to optimize health outcomes and prevent chronic diseases.
Polyphenols: Polyphenols are a diverse group of naturally occurring compounds found in plants, recognized for their antioxidant properties and potential health benefits. These compounds contribute to the color, flavor, and disease resistance in plants, and they have garnered attention in nutrition science for their possible role in reducing the risk of chronic diseases such as heart disease and cancer.
Prebiotics: Prebiotics are non-digestible food components that promote the growth and activity of beneficial bacteria in the gut. They act as a food source for probiotics, the live microorganisms that support gut health, and are crucial for maintaining a balanced microbiome. This relationship between prebiotics and probiotics is significant for various aspects of nutrition and health, leading to emerging research focused on their role in disease prevention and overall well-being.
Precision Agriculture: Precision agriculture is an innovative farming management concept that utilizes technology and data analysis to optimize field-level management regarding crop farming. This approach integrates various tools such as GPS, sensors, and big data to monitor and manage the variability in fields, aiming to increase efficiency, reduce waste, and enhance crop yields. By applying precise amounts of water, fertilizers, and pesticides only where needed, precision agriculture not only boosts productivity but also aims to promote sustainability in agricultural practices.
Probiotics: Probiotics are live microorganisms, often referred to as 'good' or 'friendly' bacteria, that provide health benefits when consumed in adequate amounts. They play a vital role in maintaining gut health, supporting immune function, and potentially preventing certain diseases. By promoting a balanced gut microbiome, probiotics can impact overall health and wellness in various ways.
Sustainable nutrition: Sustainable nutrition refers to the practice of promoting health through food choices that support the well-being of individuals and the planet. This concept emphasizes the importance of ecological balance, social equity, and economic viability, integrating nutritional needs with environmental sustainability. By focusing on sustainable food systems, it encourages dietary patterns that minimize environmental impact while ensuring access to nutritious foods for all populations.
Time-restricted eating: Time-restricted eating is an eating pattern that restricts food intake to a specific time window during the day, often involving fasting for a certain number of hours. This approach to eating has gained attention for its potential health benefits, including weight management, improved metabolic health, and enhanced cellular repair mechanisms. It aligns with emerging research in nutrition science that explores how the timing of food consumption can impact overall health.
