What Foods Help Keep Your Skin Healthy? A Doctor's Guide to Plant-Based Nutrition
Welcome to the first edition of #AskDrMonique, where I answer your nutrition and wellness questions with practical, science-backed advice.
Today's question comes from Jan.
"I do not cook with oil and avoid overly oily foods as much as possible. Unfortunately, I find my skin is very dry and flaky, particularly my face. What foods other than processed oils contribute to maintaining healthy skin?"
This is an excellent question, and one I hear often.
Many people assume dry skin means they need to eat more oil. While healthy fats are certainly important, beautiful, healthy skin is about much more than adding oil to your meals. Your skin depends on a variety of nutrients working together to support its structure, maintain its protective barrier, reduce inflammation, and keep it hydrated.
The good news is that you can nourish your skin without relying on processed oils. A whole-food, plant-based diet provides many of the nutrients your skin needs to stay healthy.
Your Skin Starts From the Inside Out
Your skin is your body's largest organ. It serves as a protective barrier against bacteria, pollutants, and moisture loss. To perform these jobs well, your skin continuously replaces old cells with new ones.
That process requires protein, healthy fats, vitamins, minerals, antioxidants, and adequate hydration. When one or more of these nutrients is lacking, your skin may become dry, flaky, irritated, or slower to heal.
Plant Foods That Support Healthy Skin
1. Flaxseed and Chia Seeds
Ground flaxseed and chia seeds are excellent sources of alpha-linolenic acid (ALA), the plant form of omega-3 fat.
Omega-3 fats help support your skin's natural barrier, which helps reduce moisture loss and may improve skin hydration.
Try this:
- Stir ground flaxseed into oatmeal.
- Blend chia seeds into smoothies.
- Make chia pudding for breakfast or dessert.
2. Walnuts
Walnuts are one of the few nuts that provide a meaningful amount of plant omega-3 fats.
They also contain vitamin E and polyphenols, compounds that help protect skin cells from oxidative stress.
A small handful makes an excellent afternoon snack.
3. Avocados
Avocados provide heart-healthy monounsaturated fats that help maintain skin flexibility and softness.
They're also rich in vitamin E, potassium, and fiber, making them beneficial for both your skin and overall health.
Add sliced avocado to salads, sandwiches, grain bowls, or enjoy it on whole-grain toast.
Looking for an easy way to add more flavor without relying on heavy, oil-based dressings? Try tossing avocado into a salad or grain bowl and finishing it with a splash of Physician In The Kitchen® Vegan Worcestershire Sauce. It adds rich, savory umami flavor to vegetables, beans, and whole grains, making it easier to enjoy more nutrient-dense, plant-based meals that support healthy skin.
4. Soy Foods
Tofu, edamame, and tempeh provide high-quality plant protein along with healthy fats.
Protein supplies the amino acids your body uses to repair skin tissue and produce collagen and other structural proteins.
Soy foods also contain beneficial plant compounds called isoflavones, which have been studied for their potential role in supporting skin health, particularly as we age.
Vitamin C Helps Your Body Build Collagen
Collagen gives skin strength and structure.
Although collagen supplements are popular, your body cannot make collagen without vitamin C.
Excellent plant sources include:
- Strawberries
- Oranges
- Kiwi
- Bell peppers
- Broccoli
- Brussels sprouts
Aim to include vitamin C-rich foods every day.
Beta-Carotene Helps Protect Skin
Orange and dark green vegetables are packed with beta-carotene, which your body converts into vitamin A.
Vitamin A supports normal skin cell growth and helps maintain healthy skin.
Great choices include:
- Sweet potatoes
- Carrots
- Pumpkin
- Butternut squash
- Spinach
- Kale
The deeper the color, the more protective plant compounds these foods typically contain.
Vitamin E Protects Skin Cells
Vitamin E acts as an antioxidant that helps protect skin cells from damage caused by everyday environmental exposure.
Good plant sources include:
- Almonds
- Sunflower seeds
- Sunflower seed butter
Because these foods also contain healthy fats, they help your body absorb other fat-soluble nutrients.
Don't Forget Hydration
Healthy skin depends on hydration from both fluids and food.
While drinking enough water is important, many fruits and vegetables naturally contain large amounts of water.
Some excellent choices include:
- Cucumbers
- Watermelon
- Tomatoes
- Oranges
- Celery
- Lettuce
These foods help support hydration while providing vitamins, minerals, and antioxidants.

Could Dry Skin Mean Something Else?
If your skin suddenly becomes much drier than usual, or if dry skin occurs along with symptoms such as fatigue, unexplained weight changes, hair loss, or feeling unusually cold, don't assume it's simply your diet.
Dry skin can sometimes be a sign of an underlying medical condition, including thyroid disease, eczema, diabetes, or certain nutrient deficiencies.
If your symptoms persist or worsen, it's important to discuss them with your healthcare provider for a proper evaluation.
The Bottom Line
Healthy skin isn't built by adding more processed oils to your meals. It's built by consistently eating a wide variety of whole plant foods that provide healthy fats, protein, vitamins, minerals, antioxidants, and plenty of water.
Feed your body well, stay hydrated, protect your skin from the sun, and your skin will often reflect those healthy choices.
Doctor's Orders
Your skin is a reflection of your overall health.
Eat a colorful variety of whole plant foods every day, including flaxseed, walnuts, avocados, soy foods, fruits, vegetables, nuts, and seeds. These foods provide the nutrients your skin needs to stay healthy and resilient.
And remember, nutrition is only part of the equation. Everyone with skin should wear a broad-spectrum sunscreen with an SPF of at least 30 every day, especially during the summer or anytime you're spending time outdoors. Sunscreen helps protect against premature aging, sunburn, and skin cancer, making it one of the most effective things you can do for lifelong skin health.
