Sacha inchi, a seed native to the Amazon rainforest, is emerging as a potential superfood due to its rich content of protein, omega-3 fatty acids, and unsaturated fats. Also known as mountain peanut or Inca nut, the seeds are derived from a star-shaped fruit and have been consumed for thousands of years in the Amazon Basin, primarily for traditional health remedies.

Today, sacha inchi is available in various forms, including whole seeds, protein powders, seed butter, and oil. It is also incorporated into skincare and haircare products. The seeds themselves are nutritionally dense; when the oil is extracted, the remaining meal comprises 53% to 59% protein. This protein is considered complete, containing all nine essential amino acids, which are vital for muscle repair, enzyme production, and immune function.

The oil extracted from sacha inchi seeds is notably rich in unsaturated fats, making up approximately 50% of the seed's composition. These fats are recognized for their benefits to heart health. Studies suggest that sacha inchi oil may help lower blood pressure and cholesterol levels, thereby reducing the risk of heart attack and stroke. Furthermore, unsaturated fats can contribute to weight management by promoting a feeling of fullness. Research has also indicated a potential role for sacha inchi oil in improving insulin resistance, a condition linked to Type 2 diabetes.

Omega-3 fatty acids constitute a significant portion, around 45% to 50%, of sacha inchi oil. Beyond cardiovascular benefits, omega-3s are associated with enhanced cognitive function, mood improvement, relief from arthritis symptoms, and protection of eye health. They also play a role in reducing inflammation throughout the body, which can be beneficial for conditions like rheumatoid arthritis. Sacha inchi offers a vegan alternative to traditional omega-3 supplements like fish oil, potentially avoiding common side effects.

Sacha inchi seeds are also a source of antioxidants, compounds that protect cells from damage caused by free radicals. These free radicals are generated by environmental factors such as tobacco smoke, UV rays, and pollution. The seeds have been found to contain a notable quantity of antioxidants, including vitamin E (tocopherols), which supports heart and skin health, and phenolic compounds, which may help mitigate chronic inflammation. Carotenoids present in the seeds are converted by the body into vitamin A, crucial for immune system function. The seeds also provide dietary fiber, calcium, and iron.

In Peru, where the plant originates, sacha inchi seeds are commonly consumed roasted and whole, similar to peanuts, a practice reflected in its indigenous Quechua name, which loosely translates to "false peanut." While the seeds can be incorporated into various dishes, potential consumers should be aware that some individuals have reported experiencing nausea after consuming sacha inchi oil, although these effects reportedly subsided over time. Allergic reactions have also been documented.
