nutrient deficiencies and supplements

Nutrient deficiencies can have significant impacts on brain function and behavior, contributing to the symptoms of ADHD. In this explanation, we will cover key terms and vocabulary related to nutrient deficiencies and supplements in the context of ADHD.

Nutrient deficiency: A lack of sufficient essential nutrients in the body, leading to impaired bodily functions and health issues.

Essential nutrients: Nutrients that the body cannot produce on its own and must obtain through diet or supplementation, including vitamins, minerals, and essential fatty acids.

Vitamins: Organic compounds that are essential for normal growth, development, and maintenance of the body's functions.

Minerals: Inorganic elements that are essential for normal growth, development, and maintenance of the body's functions.

Essential fatty acids: Types of fatty acids that the body cannot produce on its own and must obtain through diet or supplementation, including omega-3 and omega-6 fatty acids.

Dietary supplement: A product taken orally that contains a dietary ingredient intended to supplement the diet, including vitamins, minerals, herbs, or other botanicals, amino acids, or other dietary substances.

ADHD: Attention Deficit Hyperactivity Disorder, a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity.

Neurotransmitters: Chemical messengers in the brain that transmit signals between neurons and play a key role in regulating mood, cognition, and behavior.

Dopamine: A neurotransmitter involved in regulating reward, motivation, and attention.

Norepinephrine: A neurotransmitter involved in regulating arousal, attention, and mood.

Serotonin: A neurotransmitter involved in regulating mood, appetite, and sleep.

Omega-3 fatty acids: Essential fatty acids that play a critical role in brain function, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).

Omega-6 fatty acids: Essential fatty acids that play a role in brain function and inflammation, including linoleic acid (LA) and arachidonic acid (AA).

Iron: A mineral that plays a critical role in oxygen transport, energy production, and neurotransmitter synthesis.

Zinc: A mineral that plays a critical role in immune function, wound healing, and neurotransmitter synthesis.

Magnesium: A mineral that plays a critical role in nerve function, muscle relaxation, and energy production.

Vitamin B6: A vitamin that plays a critical role in neurotransmitter synthesis, including serotonin and dopamine.

Vitamin B12: A vitamin that plays a critical role in nerve function, energy production, and DNA synthesis.

Vitamin D: A vitamin that plays a critical role in calcium absorption, bone health, and immune function.

Methylation: A biochemical process that involves the transfer of a methyl group (CH3) to a molecule, playing a critical role in neurotransmitter synthesis, DNA synthesis, and detoxification.

Micronutrient: A nutrient that is required in small amounts, including vitamins and minerals.

Macronutrient: A nutrient that is required in larger amounts, including carbohydrates, proteins, and fats.

Whole foods: Foods that are unprocessed or minimally processed and contain all of their natural nutrients, including fruits, vegetables, whole grains, lean proteins, and healthy fats.

Processed foods: Foods that have been altered from their natural state, often including added sugars, sodium, and unhealthy fats, and may be lacking in essential nutrients.

Fortified foods: Foods that have had nutrients added to them, often including vitamins and minerals, to increase their nutritional value.

Bioavailability: The degree to which a nutrient can be absorbed and utilized by the body.

Tolerable Upper Intake Level (UL): The maximum daily intake of a nutrient that is unlikely to cause adverse health effects.

Recommended Dietary Allowance (RDA): The average daily intake of a nutrient that is sufficient to meet the needs of almost all (97-98%) healthy individuals.

Adequate Intake (AI): A recommended intake level based on observed or experimentally determined approximations of nutrient intake by a group (or groups) of healthy people that are assumed to be adequate.

Deficiency: A state in which the body does not have enough of a particular nutrient to meet its needs.

Toxicity: A state in which the body has too much of a particular nutrient, leading to adverse health effects.

Nutrient-dense foods: Foods that are high in essential nutrients and low in calories.

Empty calories: Calories from foods and beverages that provide little to no essential nutrients, including added sugars and solid fats.

Phytochemicals: Compounds found in plants that have potential health benefits, including antioxidant and anti-inflammatory properties.

Antioxidants: Compounds that protect cells from damage caused by free radicals, reducing the risk of chronic diseases.

Inflammation: A response to injury or infection that involves the release of pro-inflammatory cytokines, which can contribute to the development and progression of chronic diseases.

Gut microbiome: The community of microorganisms that live in the gut, playing a critical role in digestion, immunity, and brain function.

Probiotics: Live microorganisms that provide health benefits when consumed, including improving gut health and immune function.

Prebiotics: Non-digestible fibers that feed the gut microbiome, promoting the growth and activity of beneficial bacteria.

Synbiotics: A combination of probiotics and prebiotics that work together to improve gut health and immune function.

Nutrigenomics: The study of how nutrients interact with genes to influence health and disease.

Epigenetics: The study of changes in gene expression that do not involve changes to the underlying DNA sequence, often influenced by environmental factors such as diet and lifestyle.

Personalized nutrition: A tailored approach to nutrition that takes into account an individual's unique genetic, metabolic, and lifestyle factors to optimize their health and prevent chronic diseases.

Food first approach: A strategy that prioritizes obtaining essential nutrients from whole foods rather than supplements, when possible.

Supplement safety: The practice of using dietary supplements in a safe and effective manner, including following recommended dosages, avoiding contraindications, and monitoring for adverse effects.

Nutrient-gene interactions: The complex interplay between nutrients and genes that can influence health and disease, including the impact of nutrient deficiencies on gene expression and the role of genetic variations in nutrient metabolism.

Microbiome-gut-brain axis: The complex communication network between the gut microbiome, nervous system, and brain, playing a critical role in brain function, behavior, and mood regulation.

Neuroprotection: The process of preventing or delaying neuronal damage and loss, including the impact of nutrients on reducing oxidative stress and inflammation in the brain.

Cognitive function: The mental processes involved in acquiring, processing, and using information, including attention, memory, and executive function.

Mood disorders:
