Summary
Establishing recommended intakes for dietary bioactive components (DBCs) requires a new framework. Current guidelines focus on essential nutrients, not DBCs, hindering public health messages and food labeling for these beneficial compounds.
Area of Science:
- Nutritional Science
- Public Health
- Dietary Components
Background:
- Dietary Reference Intakes (DRIs) in the US cover essential nutrients but not dietary bioactive components (DBCs).
- DBCs are not considered essential, meaning their absence doesn't cause deficiency syndromes, but they offer potential health benefits.
- Existing frameworks are inadequate for setting recommended intakes for DBCs, complicating public health messaging and food labeling.
Purpose of the Study:
- To address the need for a framework to establish recommended intakes for dietary bioactive components (DBCs).
- To initiate scientific dialogue on developing guidelines for DBCs, distinct from essential nutrients.
- To discuss challenges in determining DBC intake, status, and health contributions.
Main Methods:
- Convening a special "hot topic" session at the 2014 Experimental Biology meeting.
- Facilitating discussions among experts on dietary bioactive components.
- Summarizing presentations and discussions from the session.
Main Results:
- Identified the need for a dedicated framework for recommended intakes of DBCs.
- Highlighted the challenges in assessing DBC intake, status, and health effects.
- Emphasized the importance of further scientific dialogue and research in this area.
Conclusions:
- A new framework is crucial for setting recommended intakes of DBCs.
- Public health messages and food labeling for DBCs are currently limited due to a lack of established guidelines.
- Further research and discussion are needed to develop a comprehensive approach for DBCs.

01:28Proteins: Dietary Sources and Requirements
2.5K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

01:22Bioavailability: Influencing Factors
637
Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...

01:13Bioavailability: Overview
5.2K
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...

Bioavailability refers to the proportion of an administered drug that reaches the systemic circulation in its active, unaltered form. It is a crucial pharmacokinetic parameter that determines the effectiveness of a drug in achieving its intended therapeutic outcomes. The route of administration significantly influences bioavailability, with intravenous administration achieving 100% bioavailability as the drug directly enters the bloodstream. In contrast, oral administration often results in...

2.8K
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
