Vegan Collagen Substitutes: Replenishing Proteins For Plant-Based Diets

Collagen is the most abundant protein in the human body, making up around 30% of total protein mass. It is a structural protein that plays a crucial role in the health and function of various tissues, including skin, muscles, bones, and connective tissues. While the body naturally produces collagen, its production slows down with age, leading to natural signs of ageing such as wrinkles and achy joints.

Collagen is commonly associated with animal-derived sources, but it is possible for vegans to boost their collagen production through a thoughtful selection of plant-based foods and nutrients.

- Vitamin C: This vitamin is crucial for collagen synthesis, acting as an antioxidant to protect existing collagen from damage. It is involved in the formation of collagen molecules and helps to stabilise the collagen structure. Include citrus fruits, berries, dark leafy greens, bell peppers, and tomatoes in your diet to boost vitamin C intake.

- Amino Acids: Amino acids are the building blocks of protein and are essential for collagen synthesis. Plant-based proteins such as pea protein, quinoa, tofu, tempeh, soy products, seeds, and nuts are excellent sources of amino acids like lysine, proline, and arginine, which are necessary for collagen formation.

- Silica: Silica, also known as silicon, is a mineral that assists in collagen synthesis and plays a role in the activation of enzymes responsible for collagen production. Plant-based sources of silica include oats, barley, avocados, cucumbers, asparagus, horsetail, nettle, and strawberries.

- Zinc: Zinc is a mineral that helps maintain the integrity of connective tissues and supports collagen production. Vegan sources of zinc include nuts, seeds, and beans.

- Copper: Copper increases the production and utilisation of collagen and helps facilitate the fibril structure of collagen proteins. Vegan sources of copper include sunflower seeds, lentils, almonds, apricots, dark chocolate, mushrooms, greens, and blackstrap molasses.

- Lysine: Lysine is an amino acid that helps give collagen its stability and structure. While eggs and dairy products are common sources, vegans can obtain lysine from plant-based sources such as tofu, brewer's yeast, and spirulina.

- Arginine: Arginine stimulates collagen synthesis in osteoblast-like cells, making it important for bone health. Vegan sources of arginine include sesame seeds, spirulina, coconut meat, cultured yogurt, kefir, and raw cheeses.

By incorporating these nutrients into your diet, you can naturally boost collagen production and support the health of your skin, joints, and connective tissues.

Eat vitamin C-rich foods like peppers, citrus fruits, berries, leafy greens, and avocados

Vitamin C is an essential nutrient that helps your body form and maintain connective tissue like skin and bones. It is also a powerful antioxidant, protecting your cells from damage caused by harmful molecules known as free radicals.

Vitamin C adds oxygen and hydrogen to amino acids so that they can play their part in collagen production. If you don't get enough vitamin C, collagen production will slow down.

Foods rich in vitamin C include peppers, citrus fruits, berries, leafy greens, and avocados.

Peppers

Peppers are a great source of vitamin C. Red bell peppers, for example, have 1.5 times more vitamin C than their green counterparts. A medium red pepper can provide more than 150% of your daily recommended vitamin C intake.

You can enjoy red peppers as a simple snack by cutting them into strips and pairing them with hummus or another dip. You can also roast them as a side or add them to salads, sandwiches, pizzas, omelets, or stir-fries.

Citrus Fruits

Citrus fruits, such as oranges, grapefruit, lemons, and limes, are well-known for their high vitamin C content. The amount of vitamin C in these fruits varies depending on factors such as type, size, and ripeness.

One medium orange typically contains 70-90 milligrams of vitamin C, while a grapefruit can provide 80-100 milligrams. Just one of these citrus fruits can fulfill your daily recommended dose of vitamin C.

Berries

Berries, such as strawberries, are also an excellent source of vitamin C. One cup of strawberries provides almost 150% of your daily recommended vitamin C intake. They are also a good source of dietary fiber, folate, and antioxidants, making them a nutritious addition to your diet.

Leafy Greens

Dark, leafy greens like kale, spinach, and mustard spinach are rich in vitamin C and other essential nutrients. They also have anti-inflammatory properties, which can help reduce the risk of chronic diseases like heart disease and arthritis.

Cooking these leafy greens can increase the bioavailability of health-promoting compounds, so don't be afraid to incorporate them into cooked dishes like stir-fries or omelets.

Avocados

Avocados are a unique source of vitamin C among fruits, as they are high in healthy fats. They are also a good source of potassium, vitamin E, and antioxidants.

In addition to these vitamin C-rich foods, other plant-based sources of collagen-boosting nutrients include beans, soy, nuts, and seeds.

Consume zinc-rich foods such as nuts, seeds, legumes, and whole grains

Zinc is a mineral that plays a crucial role in collagen production. It helps to slow down the breakdown of collagen, leading to an accumulation of collagen in the tissue.

• Nuts: These include pistachios, peanuts, and cashews. Nuts are also a good source of essential fatty acids, which contribute to skin health and collagen synthesis.
• Seeds: Pumpkin seeds, squash seeds, sunflower seeds, chia seeds, and flaxseeds are all great options. Seeds are also a good source of essential fatty acids.
• Legumes: Beans, such as white beans, black beans, kidney beans, and navy beans, are good sources of zinc. Legumes are also rich in proline, an amino acid essential for collagen synthesis.
• Whole grains: Oats, oatmeal, oat flour, and oat pancakes are great ways to include more zinc in your diet.

Include silica-rich foods like oats, barley, avocados, and cucumbers in your diet

While collagen is not naturally vegan, as it is a protein found mostly in animal products, it is possible to boost your body's natural collagen production by eating foods rich in silica.

Silica is a mineral that assists in collagen synthesis and plays a role in the activation of enzymes responsible for collagen production. It is present in plants as silica and soluble silicates and is bound to the cellulosic cell structure.

• Oats: Of the 18 foods with the highest silica content, 11 are cereal products, and those containing oats were at the top of the list. Two tablespoons of oat bran contain 3.27 milligrams of silica.
• Barley: Barley is another cereal product that is rich in silica.
• Avocados: Avocados are a fruit that is high in silica content.
• Cucumbers: Cucumbers are a silica-rich food, especially in the bran.

Other silica-rich foods include green beans, bananas, leafy green vegetables like spinach, brown rice, lentils, beer, apples, beets, bell peppers, cherries, celery, corn, dried beans, eggplant, grapes, honey, kelp, nuts, seeds, oranges, pumpkin, raisins, root vegetables, seafood, soybeans, strawberries, tomatoes, and whole grains.

Eat copper-rich foods, including nuts, seeds, and dark chocolate

Copper is an essential mineral that our body requires in small amounts to maintain good health. It is involved in the formation of red blood cells, bone, connective tissue, and some important enzymes.

A copper deficiency can lead to weak bones, so it is important to include copper-rich foods in your diet.
