Chemical compounds known as peptides: Their nature, applications, and potential drawbacks
Bioactive peptides, short sequences of amino acids derived primarily from food proteins, have garnered significant attention in the scientific community for their diverse health-promoting effects. These peptides, which can be found in various food sources such as eggs, milk, meat, fish, beans, and grains, are believed to offer a range of benefits, including anti-aging, skin health, muscle growth, and athletic performance enhancement.
## Potential Health Benefits of Bioactive Peptides
One of the key areas where bioactive peptides show promise is in cardiovascular health and blood pressure regulation. For instance, peptides such as isoleucine-proline-proline (IPP) and valine-proline-proline (VPP), found in fermented dairy products, have demonstrated antihypertensive effects in clinical trials. They have been shown to significantly reduce both systolic and diastolic blood pressure in hypertensive and prehypertensive individuals [1].
In addition, certain peptides help regulate blood glucose by influencing carbohydrate digestion and insulin secretion, supporting the management and prevention of diabetes and metabolic disorders [3][5]. Some peptides also contribute to gut homeostasis by reducing gut microbiota imbalance and modulating inflammatory responses, which may benefit overall immune function [2].
Antioxidant peptides, another category of bioactive peptides, neutralize reactive oxygen species, protecting cells from oxidative stress and helping to prevent age-related damage and chronic diseases [4]. Peptides like collagen peptides and branched-chain amino acids (BCAAs) are commonly used to support muscle protein synthesis, recovery, and athletic performance.
## Potential Risks
While bioactive peptides offer numerous potential benefits, it's important to be aware of the potential risks. Some individuals may experience allergic responses to certain peptide sources, especially if derived from milk, eggs, or other common allergens. High doses or certain types of peptide supplements may cause digestive discomfort, bloating, or diarrhea.
The supplement industry is not tightly regulated in many countries, leading to potential issues with purity, dosage accuracy, and product quality. Some peptides may interact with medications, particularly those affecting blood pressure or blood sugar.
## Common Types of Peptide Supplements
Some common types of peptide supplements include collagen peptides, BCAAs and EAAs (Branched-Chain and Essential Amino Acids), casein/whey peptides, fermented dairy peptides, and antioxidant peptides. Each of these supplements has its unique uses and benefits.
For example, collagen peptides are widely used for skin elasticity, anti-aging, and joint health, while BCAAs and EAAs are critical for muscle protein synthesis, muscle repair, and athletic recovery. Fermented dairy peptides, like IPP and VPP, have demonstrated blood pressure-lowering effects in clinical trials. Antioxidant peptides, such as glutathione and carnosine, protect against oxidative damage, supporting longevity and healthy aging [4].
In conclusion, bioactive peptides offer a promising avenue for improving health and wellbeing. However, it's crucial to exercise caution when considering peptide supplementation, especially for pregnant, breastfeeding, medicated individuals, or those with medical conditions. Always consult a qualified healthcare provider before starting any new supplement regimen.
