Sagging skin is a natural part of the ageing process, but certain lifestyle factors can also cause skin to sag prematurely. These include sun exposure, smoking, and an unhealthy diet. A high-sugar diet, for example, can lead to collagen degradation, causing skin to lose its natural elasticity and sag. To prevent this, it's important to eat a healthy, balanced diet that includes a range of brightly coloured fruits and vegetables. Protein is a crucial component of such a diet, as it helps to promote collagen production, giving your skin strength and structure.

Collagen-boosting foods
Collagen is the protein that gives skin its structure, firmness, and stretch. As we age, our bodies produce less collagen, leading to wrinkles and thinning skin. While collagen supplements are available, they can be pricey and may not be for everyone. A food-first approach is often preferable.
A diet rich in protein can promote smooth, firm skin. Protein supplies the body with the essential amino acids required to make keratin, which is the protein that gives hair its strength and shine. Eating collagen-rich foods can help your body make more of its own collagen.
- Bone broth is a great source of collagen, particularly beef bone broth, which is rich in collagen type I, important for skin, hair, and nail health.
- Chicken, with the skin on, is another source of collagen type I.
- Oily fish such as salmon, mackerel, sardines, and herring are loaded with omega-3 fatty acids and antioxidants, which boost collagen and elastin.
- Berries are a great source of antioxidants, which encourage firmer, more supple skin. Black raspberries are particularly good.
- Citrus fruits such as oranges and lemons are good for sagging skin due to their high vitamin C content, which is key for collagen formation.
- Green and red bell peppers are also a good source of vitamin C.
- Brazil nuts, cashews, pecans, and walnuts contain omega-3s and are great for skin health and appearance.
- Oysters are very high in zinc, which is crucial for collagen production.
- Almonds are a low-glycemic-index food with 6 grams of plant-based protein.
- Tomatoes are full of lycopene, which is beneficial for the skin.
- Garlic is high in sulfur, a trace mineral that helps synthesize and prevent the breakdown of collagen.

Lean protein sources
Protein-rich foods provide the body with amino acids, which are crucial for collagen production. Collagen is a fibrous protein that gives skin its structure, firmness, and youthfulness. A diet rich in lean protein can help compensate for the natural decline in collagen production that occurs with age.
White-Fleshed Fish
White-fleshed fish, such as cod, haddock, grouper, halibut, tilapia, and bass, are excellent sources of lean protein. They provide high protein content with minimal fat and relatively few calories. For example, a 3.5-ounce serving of Greek yoghurt contains around 100 grams of protein.
Poultry
Chicken and turkey breasts are good sources of lean protein. However, it is important to choose skinless options to reduce fat and calorie intake. A 3.5-ounce serving of roasted chicken breast with skin contains 200 calories and 8 grams of fat, while the same amount of skinless chicken breast has only 161 calories.
Lean Beef
Lean cuts of beef are those with less than 10 grams of total fat and no more than 4.5 grams of saturated fat per 3.5 ounces. Look for labels that say "loin" or "round" to indicate a leaner cut. Ground beef should be at least 90% lean.
Dairy
Dairy products like milk, cheese, and yoghurt are rich in protein, calcium, and other essential nutrients. Greek yoghurt, in particular, is a great option as it is high in protein and low in fat. Nonfat Greek yoghurt has less than 2 grams of fat per 156-gram serving.
Plant-Based Sources
Beans, peas, lentils, and tofu are good plant-based sources of lean protein. They are also high in fibre and can help lower cholesterol levels. Tofu, specifically, provides all the essential amino acids and is very versatile in recipes.

Sugar and glycation
Sagging skin can be caused by a high-sugar diet, which can lead to glycation. Glycation is a natural process in the body where sugar molecules bind to proteins or lipids to form advanced glycation end products (AGEs). These AGEs can accumulate in the skin's collagen and elastin fibres, causing them to become stiff and less flexible, resulting in a loss of the skin's natural elasticity and leading to sagging.
AGEs affect collagen flexibility and promote collagen fibre breakdown, accelerating the development of sagging skin. High-sugar diets can also trigger inflammation throughout the body, including the skin, and chronic inflammation can damage skin cells and disrupt collagen and elastin production. This process is accelerated in all body tissues when sugar intake is elevated and is further stimulated by ultraviolet light on the skin.
Glycation is implicated in several diseases and age-related chronic conditions, including cardiovascular diseases, renal failure, atherosclerotic heart disease, and Alzheimer's disease. It is also responsible for many complications in diabetes mellitus, such as vascular complications.
To prevent glycation and its effects on the skin, it is important to limit sugary foods and beverages and maintain a well-balanced diet with adequate protein and vitamin C intake. Protein is crucial for collagen production, and vitamin C helps stabilise the collagen structure, making the skin firm and youthful.

Skin hydration
A well-balanced diet is also fundamental to skin hydration. A high-sugar diet can contribute to saggy skin by triggering glycation, a process where sugar molecules bind to proteins, forming advanced glycation end products (AGEs). These AGEs accumulate in the skin's collagen and elastin fibres, causing them to stiffen and lose flexibility, leading to skin sagging. Therefore, limiting sugary foods and beverages is essential for maintaining skin firmness.
To promote skin hydration, it is recommended to include vitamin C-rich foods in your diet. Vitamin C is vital for collagen synthesis and helps protect the skin from sun damage. Citrus fruits, such as oranges and lemons, are excellent sources of vitamin C, and their antioxidant properties contribute to skin health and reduce the appearance of dark spots. Additionally, green and red bell peppers are also rich in vitamin C, offering similar benefits.
Protein plays a crucial role in skin hydration and firmness. A high-protein diet strengthens collagen levels, making the skin firmer and reducing wrinkles. Lean protein sources, such as poultry, fish, tofu, and legumes, are particularly beneficial for maintaining skin elasticity and preventing sagging. Furthermore, protein supplies the body with essential amino acids, including L-lysine and L-proline, which are necessary for collagen production.
Other dietary recommendations for improving skin hydration and reducing sagging include incorporating omega-3 fatty acids, found in oily fish like salmon and mackerel, and plant sources such as walnuts, chia, and flax. These omega-3 fatty acids boost skin elasticity and possess anti-aging properties. Additionally, antioxidants, found in plant-based foods, help neutralize free radicals that contribute to skin aging, promoting overall skin health and hydration.
