Peptides are a protein component composed of two or more amino acids bonded in a chain and encrypted into the protein molecule. Most dietary peptides remain inactive while contained in sequence within their respective parent proteins and are only activated when digested by the appropriate enzymes in the gastrointestinal tract or via food processing or fermentation. Many of the health-promoting properties associated with proteins, including nutrient absorption and cardiovascular, endocrine, immune and nervous system benefits, may actually be attributed to the peptides encrypted into those protein molecules.
All dietary proteins contain peptides, but milk, eggs, grains and soybeans are among the richest sources. Dairy products are among the richest dietary sources of peptides, with several identified in the milk protein casein alone.
In a article in "Archivos Latinoamericano De Nutricion," or the "Latin American Archives of Nutrition," peptides in casein and whey, another milk protein, were found to display an array of therapeutic activities, including antimicrobial, antithrombotic, mineral-carrying and immunomodulatory effects.
According to a report in "Current Pharmaceutical Design," bioactive peptides effective against hypertension have been found in whey, ripened cheese and fermented milk products, such as yogurt. Next to milk, eggs are one of the richest dietary sources of peptides. In a study published gap filling test in "Menopause," the journal of the North American Menopause Society, a peptide contained in egg yolk called egg yolk water-soluble peptide, or YPEP, proved to have a protective effect on bone metabolism, leading the researchers to deem YPEP a promising alternative to current osteoporosis therapies.
Corn, rice and wheat all contain peptides. In a report in "Science," researchers identified the autoimmune trigger in wheat gluten that induces celiac disease as a peptide.
A report in the "International Journal of Biological Sciences" found that an effective "edible vaccine" against Alzheimer's disease may be derived from a peptide contained in rice. As ofover 80 different peptides known as plant defensins have been identified with antifungal properties, including several in corn and rice. Soybeans and other beans and seeds contain peptides as well. Numerous recent studies have identified various peptides in soybeans and associated them with specific health benefits, such as a study reported in "Experimental and Molecular Medicine" that confirmed the cancer-preventing and tumor-suppressing effects of the soybean peptide known as isoflavone-deprived soy peptide.

Keeping a healthy diet can help fight wrinkles, moisturize your skin and and even protect against UV damage. If you want to fight aging from the inside out, try incorporating foods that include these five nutrients. Antioxidants are chemicals that help fight against cell-damage from environmental factors such as UV rays, smoking, and unhealthy foods.
Nutrients such as vitamin C and vitamin E help protect against sun damage, boost collagen levels and reduce fine lines and wrinkles. Antioxidant-rich foods include many fruits and vegetables, coffee, tea, nuts and oil.
Found in fatty fish such as tunasalmon and sardines as well as in foods such as flaxseed, walnuts, and chia seeds, this nutrient is responsible for bolstering the cell membrane of your skin, which helps keep in moisture.
Good sources of amino acids include meat, fish, eggs, tofu some grains, nuts and seeds. Fermented foods are not only good for your gut, but for your skin as well. Photo by Infomastern.

Here are the general levels of estrogen that should be found in women during specific age periods of their lives. As previously mentioned, menopause commonly causes decreased levels of estrogen in females. However, women of all ages can experience low estrogen levels from a variety of causes, including hysterectomies partial or complete removal of the reproductive organsradiation treatments, and severe cases of anorexia.
A common and well-known consequence of low estrogen levels is the increased fragility of bones seen in post-menopausal women, leading to osteoporosis. Estrogen is known to work in conjunction with calcium, vitamin D, and other minerals to keep bones strong, and without it, bones become brittle and tend to fracture more easily.
There are several estrogen-rich foods that may help boost your estrogen level. These foods contain phytoestrogen, which is a plant-based estrogen that mimics estrogen once it is processed by the body.
The following is a list of foods that are known for containing excessive amounts of phytoestrogens. It is important to keep in mind that estrogen rich foods may have unwanted effects in men. Soybean products: Soy is a rich source of phytoestrogen and comes in a variety of easy to consume forms like soy milk, tofu, or edamame. Soy products are the greatest source of isoflavones, a class of phytoestrogen that can be easily consumed in your diet.
Soy is also a great source of protein, making it an ideal meat substitute for vegans and vegetarians. Flaxseeds: These little seeds contain up to three times the phytoestrogens of soybeans, but your body will not reap their benefits unless they are cracked or ground prior to consumption. Also high in fiber, flaxseeds will make you feel full and may aid in weight loss and in the reduction of cholesterol. Sesame seeds: Whole seeds—or even sesame oil—contain lignans a chemical compound found in plants that possess phytoestrogens.
The seeds are also loaded with fiber and are a great source of minerals. Beans are known for having a high fiber content, which helps to control cholesterol levels. Types of beans include peas, pinto bean, and lima beans. Dried Fruit: Not only are they a healthy snack, but they also contain a modest amount of phytoestrogens. It is advised to limit how much you eat, as dried fruit does contain a lot of calories.
Apricots, dates, and prunes are good sources. Bran: Wheat bran is a reliable way get your dose of phytoestrogens. It can be found in muffins, bread, and cereals.Collagen is created from proline. Buy proline supplements from Amazon. Proline has a unique structure. The side chain of the molecule connects to the protein backbone at two points. This forms a ring which is not part of the structure of other amino acids. This means proline is a secondary amino acid, sometimes called an imino acid.
It is the only imino proteinogenic acid of its type therefore people often refer to it as an amino acid. For the purpose of this article, it will be regarded as an amino acid due to its important role in protein synthesis. L-proline is a non-essential amino acid manufactured mainly from ornithine, glutamineand glutamate in the liver. It is one of the principal amino acids which the body uses to build collagen. Collagen is a structural protein which forms the elastic fibres in the skinbones, ligaments and tendons.
Together with lysine and vitamin C, proline is converted into hydroxylysine and hydroxyproline to help form collagen. The skin is the largest organ of the body, and maintaining healthy skin is important. This is because our skin is the first immune defense protecting the body from infection.
The body uses hydroxyproline to synthesis collagen and aid skin elasticity and thickness. Aged skin is characteristically thinner and less fibrous due to a decline in collagen production. Combined with UV exposure and free radical damage, the skin becomes less smooth and more wrinkled.
This loss of texture and structure accelerates the appearance of aged skin. Research has found that proline supplementation, along with other key amino acids can elevate collagen production.
Murakami and colleagues investigated the importance of various amino acids in restoring dermal collagen protein synthesis in mice after exposure to UV irradiation. The researchers concluded that proline along with branched-chain amino acids BCAAs and glutamine could enhance collagen synthesis in animals 1.
Additionally, proline has been found to increase collagen synthesis in human fibroblast cells together with its precursors, glutamate and pyrrolinecarboxylate 2. Thus, by increasing the availability of this amino acid it may be possible to slow down the aging process and enhance skin health.
During times of injury where there is soft tissue damage, the body increases proline production.
This helps to heal the wound. Animal studies have shown that topical administration of l-proline at the wound site can accelerate healing much faster than oral administration 34. Medical dressings that use collagen fragments to initiate wound healing also include this amino acid. In some cases, a deficiency in proline may be responsible for a higher susceptibility to tears or strains of soft tissues. A lack of this amino acid may also lead to slower than average healing times.
Arteriosclerosis is a process in which the arteries become thick and hard.
Foods High in Proline
This is the leading cause of heart disease. This condition develops as the arteries become stiff due to fat accumulating on the walls of the arteries. This restricts the transport of nutrients and oxygen throughout the body. The reduced blood flow and build up of pressure causes heart attacks. There is evidence to support the use of proline and other amino acids and vitamins to prevent arteriosclerosis 56.
This amino acid helps to strengthen the artery walls and protect the endothelium layer 7. Proline deficiencies are extremely rare as it is widely available in many different foods. People at risk of having low levels are typically following a protein restricted diet. Endurance runners and people that participate in prolonged exercise routines may have a greater requirement for this amino acid.We have sorted our complete nutrition and vitamin database of over foods based on the amount of Proline.

Aging, sun exposure and injuries can weaken these proteins, causing tissues to lose strength and elasticity. Foods containing certain nutrients may support tissue health and help your body build them back.
Your body uses vitamin C for tissue growth and repair, and this powerful antioxidant is central to any regimen for building collagen and elastin. Adult women need a minimum of 75 milligrams of vitamin C a day, and slightly more during pregnancy and lactation, while men require 90 milligrams daily.
Luckily, vitamin C is plentiful in produce, making it easy to get all you need. The richest fruit sources of vitamin C include:. For vegetables, a half-cup serving of any of the following will provide plenty of your daily vitamin C:. For skin health, vitamin C may also work topically to improve the appearance of wrinkles and sagging caused by collagen and elastin fibers breaking down.
A diet that includes healthy protein foods will support the growth and maintenance of collagen and elastin fibers. Proline and lysine, in particular, work with vitamin C in the formation of collagen. Protein foods that are good sources of these amino acids include:. In the skin, the dermis — the layer underneath the epidermis, or surface — consists mostly of collagen and elastin.
Essential fatty acids play an important role in reducing the damage done to these tissues by normal aging and exposure to the sun. In particular, omega-3 fatty acids support tissue growth and integrity. You can obtain these healthy fats through fish such as salmon, herring and sardines, while plant-based omega-3s occur primarily in flaxseeds and flaxseed oil, chia seeds and walnuts.
Foods containing phytonutrients known as carotenoids may also help build collagen and elastin fibers. In one study, published in Nutrients infemale participants received supplements of curly kale extract and other carotenoids daily.
Researchers noted results after five and 10 months, finding the increase of carotenoids in the skin supported the growth of collagen and elastin fibers in the cheek and forearm areas.
Leafy greens like kale, spinach, collards and dandelion greens provide rich amounts of carotenoids, as do orange-colored foods such as carrots, pumpkin, winter squash and sweet potato.

Eat Foods That Contain These 5 Things To Fight Aging
Collagen gives your skin its strength and assists with wound healing, while elastin keeps it firm and tight. As you get older, the network of collagen and elastin fibers in your skin begins to degrade, leading to eventual wrinkles and sagging. Vitamin C, working with a phytonutrient called anthocyanin, strengthens collagen, while copper is needed for the proper formation of these two proteins. Eating fruits high in these nutrients may support healthier skin as you age.
Your body needs vitamin C for the formation and growth of all its tissues, including skin. This nutrient is particularly important for the synthesis of collagen, which forms the basis of a matrix of fibers that gives your skin support.
Vitamin C is also a powerful antioxidant that helps shield your cells from oxidative damage. Women require 75 milligrams of vitamin C daily, while men need 90 milligrams.
Phytonutrients are compounds found naturally in plants that give them their bright colors and protect them against disease and bacteria. Among the thousands of phytonutrients are anthocyanins, which are responsible for the deep blue, red and purple colors of fruits and vegetables.
Anthocyanins work with vitamin C to create cross-links that reinforce and strengthen collagen fibers. The high antioxidant activity of this nutrient also helps protect the collagen in skin from oxidative damage caused by the aging process.
Copper is an essential trace mineral that assists with the metabolism of ascorbic acid, or vitamin C. It works in conjunction with vitamin C toward the maturation of collagen and the formation of elastin.
Adults require micrograms of copper daily.
Top 100 Sources of Proline
Many fruits are rich sources of vitamin C, but oranges are perhaps the best known, providing 83 milligrams in 1 cup of orange sections. A cup of sliced kiwi, however, provides twice that amount, with milligrams. Sliced strawberries also offer more vitamin C than oranges, with A team of Japanese researchers studied passion fruit, which contains 70 milligrams of vitamin C in 1 cup, for its ability to assist with collagen synthesis.
Fruits high in anthocyanins also supply vitamin C. Blueberries, bilberries, boysenberries, sweet cherries, dark red and purple grapes, raspberries and strawberries all contain anthocyanins in varying amounts, with bilberries and blackberries offering the most. Enjoy berries throughout the summer months, when they are abundant, and freeze them for use in the winter.
Dried fruits supply copper in abundance. A cup of pitted prunes, for example, provides micrograms of copper, while a cup of dried apricots contains micrograms. The same serving of dried figs yields micrograms of copper, and a cup of raisins offers micrograms of the mineral. Be aware, though, that dried fruits contain significantly more sugar and calories than fresh fruits.
They also offer much less vitamin C than their fresh counterparts.
