The Connection Between Ancestral Diets and Healthy Skin

The Modern Diet and the Rise of Acne Today

Most people eat diets high in refined carbohydrates and omega-6 seed oils. This combination triggers insulin spikes, IGF-1 signaling, chronic inflammation, and oxidative stress. These metabolic disruptions show up on the skin as:

• Excess oil production

• Congested pores

• Irritated follicles

• Overgrowth of acne-related bacteria

• Redness and swelling

  
  

The skin is not malfunctioning. It is reacting to the internal environment created by modern dietary patterns.

How Oxalates Contribute to Skin Irritation

Oxalates are sharp, reactive plant compounds found in foods such as spinach, almonds, beetroot, sweet potatoes, and many leafy greens. When eaten in excess or when gut health is compromised, oxalates can accumulate in tissues and create irritation. Oxalates contribute to skin issues by:

• Binding to minerals like calcium, zinc, and magnesium, preventing their absorption

• Creating microscopic crystals in tissues for susceptible individuals

• Triggering inflammatory responses that manifest as rashes, itching, or burning sensations

• Challenging the liver and kidneys, which increases the load on the skin

  
  

For people with existing skin conditions or those in the early stages of a carnivore transition, oxalate dumping can worsen temporary flare-ups as the body clears stored crystals. Reducing high oxalate plant foods allows the body to stabilize mineral status, reduce irritation, and restore a calmer skin presentation.

Seed Oils and Topical Skin Damage

Most commercial skincare products contain industrial seed oils such as sunflower, safflower, canola, grapeseed, or soybean oil. These oils are fragile, highly processed, and prone to oxidation. When applied to the face, seed oils can:

• Clog pores due to their unstable fatty acid structure

• Promote bacterial growth

• Increase oiliness by disrupting the natural lipid barrier

• Cause inflammation and redness

• Oxidize on the skin, contributing to premature aging

  
  

Sebum is designed to be stable and protective. Seed oils disrupt this balance and create the perfect environment for acne and irritation. By contrast, tallow is nature’s closest match to the structure of human sebum. It absorbs cleanly, supports barrier repair, and does not clog pores.

What This Means for You

If you struggle with acne, rosacea, rashes, eczema, or general irritation, consider a two-sided approach:

Inside:

• Remove high oxalate and high lectin plant foods

• Minimize refined carbohydrates

• Remove seed oils from your diet

• Eat nutrient-dense animal foods rich in bioavailable vitamins and minerals

  
  

Outside:

• Avoid seed oil-based skincare

• Choose products made with grass-fed and finished tallow

• Support your skin barrier with gentle natural ingredients

• Reduce inflammation rather than trying to strip or dry the skin

  
  

The combination of ancestral eating and ancestral skincare creates an environment in which your skin can return to balance.

The Importance of Nutrient-Dense Foods

Nutrient-dense foods are crucial for skin health. They provide the vitamins and minerals necessary for skin repair and regeneration. Foods rich in omega-3 fatty acids, for example, can help reduce inflammation and promote healthy skin. Incorporating these foods into your diet can significantly improve your skin's appearance and overall health.

Embracing Tallow-Based Skincare

Tallow-based skincare is gaining popularity for its skin-nourishing properties. Tallow is rich in vitamins A, D, E, and K, which are essential for skin health. It closely resembles human sebum, making it an excellent moisturizer that supports the skin barrier. By using tallow-based products, you can nourish your skin without the harmful effects of seed oils.

Conclusion

In conclusion, our ancestors had a profound understanding of the connection between diet and skin health. By adopting an ancestral approach to nutrition and skincare, we can address modern skin issues effectively. Embrace nutrient-dense animal foods and tallow-based skincare to restore your skin's natural balance.

Wishing you health, happy tummies, and even happier skin!

Love,
