Dosage

Children: Dietary recommendations for children vary based on age, growth rate, and developmental needs. It is advised to consult pediatric dietary guidelines to ensure appropriate nutrition.

Adults: Dietary intake should be tailored to individual needs based on age, sex, activity level, and health status. General guidelines suggest a balanced diet comprising fruits, vegetables, whole grains, lean proteins, and healthy fats.

Mechanism of action

Dietary substances work through various mechanisms depending on their composition. Macronutrients like carbohydrates, proteins, and fats provide energy and building blocks for cellular processes. Micronutrients, including vitamins and minerals, are involved in enzymatic reactions, hormone production, and maintaining physiological balance. For example, vitamin D aids in calcium absorption, while omega-3 fatty acids play a role in anti-inflammatory pathways.

Pharmacodynamics

The pharmacodynamics of dietary components is complex, as they interact with numerous biological pathways and systems. Macronutrients influence metabolic pathways, while micronutrients are crucial for enzymatic functions. For instance, antioxidants found in fruits and vegetables help mitigate oxidative stress, and dietary fiber supports gut health and regulates blood sugar levels. The balance and composition of dietary intake can significantly influence body weight, immune response, and overall metabolism.

Pharmacokinetics

The pharmacokinetics of dietary substances varies widely. Nutrients are absorbed in the gastrointestinal tract, with macronutrients primarily absorbed in the small intestine. The bioavailability of certain vitamins and minerals can be affected by factors such as food matrix, presence of other nutrients, and individual digestive health. After absorption, nutrients enter the bloodstream, distributing to tissues where they exert their effects. Excess amounts may be stored (e.g., fat-soluble vitamins) or excreted (e.g., water-soluble vitamins).

Indications

• Constipation
• Diarrhea
• Irritable bowel syndrome
• Hyperlipidemia
• Diabetes management
• Weight management

Dosage

Children: Refer to the BNF for Children for specific recommendations on dietary fiber intake in children.

Adults: Recommended daily intake of dietary fiber for adults is about 25-30 grams per day, obtained from a variety of food sources.

Mechanism of action

Fibre works by increasing the bulk of the stool and slowing down digestion, which helps to maintain bowel regularity. Soluble fiber can form a gel-like substance in the gut, which can bind to cholesterol and glucose, aiding in their elimination and absorption respectively. This mechanism helps in managing conditions like hyperlipidemia and diabetes.

Pharmacodynamics

Fibre has various effects on the body, including improving bowel health, lowering cholesterol levels, controlling blood sugar levels, and aiding in weight management. It may also enhance the absorption of nutrients and promote a healthy gut microbiome by serving as a prebiotic.

Pharmacokinetics

Fibre is not digested by human enzymes and passes through the gastrointestinal tract largely intact. Soluble fiber is fermented by gut bacteria, producing short-chain fatty acids that can have beneficial effects on metabolism and gut health. The rate of fermentation and transit time can vary based on the type of fiber and individual digestive health.

Adverse effects

• Bloating
• Gas
• Abdominal cramping
• Diarrhea
• Constipation

Precautions

• Increase fiber intake gradually to allow the digestive system to adjust
• Ensure adequate hydration when increasing fiber intake
• Consult a healthcare provider if there are pre-existing gastrointestinal conditions

Pregnancy

Fiber is generally safe to consume during pregnancy and can help manage constipation, a common issue during this period.

Breast-feeding

Fiber is safe during breastfeeding and can aid in postpartum digestive health.

Storage

Store in a cool, dry place, away from direct sunlight.

Dosage

Children: Refer to the BNF for Children for specific dosing information.

Adults: Refer to the BNF for specific dosing information.

Mechanism of action

Phosphorus decreases the absorption of intercellular calcified cartilage matrix by osteoclasts in the metaphyseal region of growing bones. This results in the formation of 'phosphorus bands' of increased bone density and thickness. Additionally, exposure to white phosphorus impairs protein synthesis by damaging the rough and smooth endoplasmic reticulum, leading to an accumulation of triglycerides in the liver and resulting in hepatic steatosis and fibrosis.

Pharmacodynamics

Phosphorus is vital for the formation of hydroxyapatite in bone, which is necessary for maintaining bone density and strength. It also plays a significant role in energy transfer through ATP and in cellular signaling pathways. The balance of phosphorus in the body is tightly regulated, as both deficiency and excess can lead to serious health issues, including bone disorders and metabolic dysfunctions.

Pharmacokinetics

Phosphorus is absorbed primarily in the intestines, with bioavailability influenced by dietary factors. It is distributed throughout the body and is predominantly found in bones and teeth. Phosphorus is excreted mainly via the kidneys, with regulation occurring through various hormonal mechanisms, including parathyroid hormone and calcitriol. The half-life can vary depending on dietary intake and individual metabolism.

Pregnancy

Phosphorus is generally regarded as safe during pregnancy when consumed in appropriate dietary amounts. However, excessive phosphorus intake should be avoided as it may lead to complications.

Breast-feeding

Phosphorus is excreted in breast milk, but it is essential for the health of both the mother and the infant. Supplementation should be considered carefully.

Storage

Store in a tightly closed container, in a cool, dry place away from direct sunlight.

Mechanism of action

Phosphorus apparently decreases the absorption of intercellular calcified cartilage matrix by osteoclasts, in the metaphyseal region of growing bones. Administration of phosphorus to growing animals or children produces "phosphorus bands" of increased bone density and thickness that are visible grossly or from radiograms. The "phosphorus bands" are observed in the metaphyseal region of growing bones, and represent areas of decreased absorption of the calcified cartilage matrix. Exposure to white phosphorus has been shown to damage the rough endoplasmic reticulum and cause a disaggregation of polyribosomes. This damage results in impairment of protein synthesis, in particular, a decrease in the synthesis of the apolipoprotein portion of very low density lipoproteins (VLDL), which are required for the transport of triglycerides. A significant decrease in protein synthesis has been detected as early as 3 hours after oral exposure. The smooth endoplasmic reticulum is also involved in the formation of the VLDLs, and damage to the smooth endoplasmic reticulum also impairs the formation of VLDLs. The net result of these ultrastructural changes is an accumulation of triglycerides in the liver. This results in steatosis and fibrosis, which is one of the mechanisms involved in the hepatotoxicity of white phosphorus. The mechanism behind the damage to the endoplasmic reticulum is not known; also, it is not known whether white phosphorus itself or a metabolite of white phosphorus is the damaging agent. In addition to these damages, white phosphorus or a metabolite causes damage to the mitochondria and nuclei in the livers of animals orally exposed to white phosphorus. The damage to the mitochondria may impair the cell's ability to produce ATP, thus resulting in necrosis of the cell. Fatty infiltration and/or cellular damage has also been observed in the kidney, brain, and heart. It is possible that white phosphorus (or a metabolite) also impairs the ability of cells in these organs to produce ATP. The mitochondrial damage may also inhibit fatty acid oxidation (also contributing to the decreased availability of ATP) which could result in an accumulation of fat in the organs.
