Is Ground Beef a Good Source of Collagen
Collagen is the most abundant protein in the body. Its fiber-similar construction is used to brand connective tissue. Similar the name implies, this type of tissue connects other tissues and is a major component of bone, pare, muscles, tendons, and cartilage. Information technology helps to make tissues strong and resilient, able to withstand stretching.
In food, collagen is naturally found only in brute flesh like meat and fish that contain connective tissue. However, a diversity of both animal and plant foods comprise materials for collagen production in our own bodies.
Our bodies gradually make less collagen equally we historic period, only collagen production drops most quickly due to excess sunday exposure, smoking, excess alcohol, and lack of sleep and exercise. With crumbling, collagen in the deep skin layers changes from a tightly organized network of fibers to an unorganized maze. [1] Environmental exposures tin damage collagen fibers reducing their thickness and force, leading to wrinkles on the skin's surface.
Collagen Supplementation
Despite its abundance in our bodies, collagen has become a summit-selling supplement purported to improve pilus, pare, and nails—cardinal components of the fountain of youth. The idea of popping a pill that doesn't take side effects and may reverse the signs of aging is attractive to many. According to Google Trends, online searches for collagen have steadily increased since 2014.
Collagen first appeared as an ingredient in skin creams and serums. However, its effectiveness equally a topical application was doubted even by dermatologists, equally collagen is not naturally establish on the skin'south surface only in the deeper layers. Collagen fibers are too big to permeate the skin's outer layers, and enquiry has not supported that shorter bondage of collagen, chosen peptides, are more successful at this feat.
Oral collagen supplements in the grade of pills, powders, and sure foods are believed to be more than effectively absorbed by the body and have skyrocketed in popularity amidst consumers. They may be sold equally collagen peptides or hydrolyzed collagen, which are cleaved down forms of collagen that are more hands absorbed. Collagen supplements incorporate amino acids, the edifice blocks of protein, and some may also incorporate additional nutrients related to healthy skin and hair like vitamin C, biotin, or zinc.
What does the inquiry say on collagen supplements?
Almost enquiry on collagen supplements is related to joint and skin health. Homo studies are lacking merely some randomized controlled trials have constitute that collagen supplements amend skin elasticity. [3,iv] Other trials have found that the supplements tin can improve joint mobility and decrease joint pain such every bit with osteoarthritis or in athletes. [5] Collagen comprises about sixty% of cartilage, a very firm tissue that surrounds bones and cushions them from the daze of high-impact movements; so a breakup in collagen could lead to a loss of cartilage and joint problems.
However, potential conflicts of interest exist in this surface area considering most if not all of the research on collagen supplements are funded or partially funded by related industries that could benefit from a positive written report result, or ane or more of the report authors accept ties to those industries. This makes information technology difficult to determine how effective collagen supplements truly are and if they are worth their often hefty cost.
A downside of collagen supplements is the unknown of what exactly it contains or if the supplement will do what the label promotes. There are also concerns of collagen supplements containing heavy metals. In the U.S., the Food and Drug Assistants does not review supplements for prophylactic or effectiveness before they are sold to consumers.
Another potential downside is that taking a collagen supplement can become an excuse to non practice good for you behaviors that tin can protect against collagen turn down, such as getting plenty slumber and stopping smoking.
That said, the available research has not shown negative side furnishings in people given collagen supplements. [iii,4]
Can You Eat Collagen?
There is a lack of research to show that eating collagen can direct benefit pare or joint health. When digested in the stomach, collagen is cleaved down into amino acids, which are then distributed wherever the body most needs protein. Even so, many foods that support collagen product are mostly recommended as part of a healthful eating plan.
Food containing collagen
- There are foods rich in collagen, specifically tough cuts of meat full of connective tissue like pot roast, brisket, and chuck steak. However, a high intake of ruby-red meat is not recommended as part of a long-term healthy and environmentally sustainable nutrition. Collagen is also found in the bones and pare of fresh and saltwater fish. [2]
- Bone broth, a trending food featured prominently in soup aisles, is promoted as a wellness food rich in collagen. The process involves simmering fauna bones in water and a small corporeality of vinegar (to help dissolve the os and release collagen and minerals) anywhere from 4 to 24 hours. However, the amount of amino acids will vary among batches depending on the types of bones used, how long they are cooked, and the corporeality of processing (due east.g., if information technology is a packaged/canned version).
- Gelatin is a form of collagen fabricated by boiling animal bones, cartilage, and skin for several hours and then allowing the liquid to absurd and ready. The breakdown of these connective tissues produces gelatin. Collagen and its derivative, gelatin, are promoted on certain eating plans such as the paleo nutrition.
Foods to heave collagen production
- Several high-protein foods are believed to nurture collagen production because they contain the amino acids that make collagen—glycine, proline, and hydroxyproline. [6] These include fish, poultry, meat, eggs, dairy, legumes, and soy.
- Collagen production too requires nutrients similar zinc that is establish in shellfish, legumes, meats, nuts, seeds, and whole grains; and vitamin C from citrus fruits, berries, leafy greens, bong peppers, and tomatoes.
Is bone broth salubrious?
Os broth has been eaten for centuries in various cultures because it is easy to digest and believed to have healing properties. Chicken broth is highly valued by some every bit a remedy for the flu. In more contempo years it has been promoted to help symptoms from psychiatric and neurodevelopmental disorders including autism and attention-arrears hyperactivity. [7] Claims that information technology detoxifies the liver, improves digestion, reverses wrinkles, builds bones, and relieves join pain have led some marketing analysts to predict that the bone broth market will arroyo $three billion by 2024. [8]
In reality, bone broth contains only minor amounts of minerals naturally found in bone including calcium, magnesium, potassium, iron, phosphorus, sodium, and copper. The corporeality of protein, obtained from the gelatin, varies from v-x grams per loving cup.
There is some business organization that bone broth contains toxic metals similar lead. 1 minor report establish that bone broth fabricated from chicken bones contained three times the lead as chicken broth made with the meat only. [7] However the amount of atomic number 82 in the bone broth per serving was still less than one-half the amount permitted by the Ecology Protection Agency in drinking water. A different report found that os broth, both bootleg and commercially produced, contained low levels (<five% RDA) of calcium and magnesium as well equally heavy metals similar lead and cadmium. [ix] The report noted that diverse factors tin touch the corporeality of protein and minerals extracted in bone goop: the amount of acidity, cooking time, cooking temperature, and blazon of animal bone used. Therefore information technology is probable that the nutritional value of bone broths volition vary widely.
Healthy Lifestyle Habits That May Help
Forth with a healthy and balanced diet, here are some habits that may assistance protect your body'south natural collagen:
- Wear sunscreen or limit the amount of time spent in direct sunlight (ten-20 minutes in direct midday sunlight 3-4 times a week provides adequate vitamin D for most people).
- Get adequate sleep. For the average person, this means 7-ix hours a nighttime.
- Avoid smoking or secondhand smoke.
- Command stress. Chronically loftier cortisol levels can decrease collagen production.
- Although the exact connectedness betwixt exercise and skin quality is unclear, some studies accept found that exercise slows down cell activeness involved with aging skin. [10]
Bottom Line
At this time, non-industry funded research on collagen supplements is lacking. Natural collagen production is supported through a healthy and balanced diet by eating plenty poly peptide foods, whole grains, fruits, and vegetables and reducing lifestyle risk factors.
