Vitamins

Sunflower seeds have over two times more vitamin B1 (thiamin), 2.5 times more B2 (riboflavin), and four times more B6 (pyridoxine) and E. In a 100g serving, sunflower seed and peanut have 35.17mg and 8.33mg of vitamin E, respectively. 

In contrast, peanuts have more vitamin B5 (pantothenic acid), folate, and 1.5 times more vitamin B3 (niacin). Moreover, sunflower seeds have 1.4mg of vitamin C and 50IU of vitamin A, whereas peanuts lack them. Both do not have vitamins K, D, and B12.

Vitamin Comparison

Minerals

Sunflower seed has more phosphorus, magnesium, zinc, iron, manganese, choline, and copper. Sunflower seed also has over seven times more selenium. In a 100g serving, sunflower seed and peanut have 53µg and 7.2µg of selenium, respectively. 

On the other hand, peanuts provide more potassium and calcium. Compared to peanuts, sunflower seed has over two times less sodium content. In a 100g serving, sunflower seed and peanut have 9mg and 18mg of sodium, respectively.

Oxalate

The oxalate content of peanuts is equal to 76mg. Sunflower seeds are oxalate-free.

Glycemic Index

Peanuts have a glycemic index of 13. The glycemic index of sunflower seeds is equal to 20. Sunflower seeds tend to have a higher glycemic index than peanuts. However, the glycemic index of both falls in the low category.

Acidity

The Potential Renal Acid Load (PRAL) is a method used to measure the acidity of the food. The PRAL value indicates the food's ability to break down into acids or bases inside the body. Sunflower seeds have a PRAL value of 11.6, whereas the PRAL level for peanuts is 6.2. That means sunflower seeds are more acid-forming than peanuts.

Cardiovascular Health

Section reviewed by cardiologist Astghik Grigoryan

The intake of peanuts positively impacts high-density lipoprotein (HDL), particularly when considering the type of peanut oil, such as high-oleic peanut oil and peanut sprouts, and when consumed by healthy individuals. However, peanut consumption shows no significant influence on other cardiovascular disease (CVD) risk factors (3).

Sunflower seeds contain chlorogenic acid, which may reduce low-density lipoprotein (LDL) oxidation susceptibility and decrease LDL cholesterol and triglycerides (TG) levels in the blood (1).

In addition, sunflower seeds are an excellent source of magnesium and can significantly contribute to reducing arterial blood pressure. Consuming 100g of these seeds can cover up to 77% of the daily magnesium requirement.

Diabetes

According to the study, seeds like sunflower, flax, and pumpkin play a role in lowering glucose levels and the risk of developing diabetes and treating type 2 diabetes. Bioactive components, such as chlorogenic acid in sunflower seeds, help with insulin resistance in pre-diabetic persons and regulate glucose and insulin metabolism (4). 

According to the study, consuming more nuts and peanut butter may lower the risk of type 2 diabetes in women (5). 

The high MUFA content of peanut butter may also promote insulin sensitivity and encourage a decrease in the glycemic response in insulin-resistant individuals. Peanuts are high in arginine and protein, which act as insulin secretagogues. They also contain a high concentration of zinc, which may activate the tyrosine kinase receptor and improve insulin sensitivity (2). 

Allergy

Common triggers for hypersensitivity reactions account for 90% of cases, including cow's milk, egg, soy, wheat, peanuts, tree nuts, fish, and shellfish. Among these, peanuts/tree nuts are particularly notable as a prevalent food allergen, capable of inducing severe and potentially fatal reactions upon ingestion. Peanut allergies typically manifest in the early years of life and often persist throughout one's lifetime, posing a constant risk of life-threatening reactions (6).

Symptoms related to the skin encompass urticaria, angioedema, and intermittent exacerbation of pre-existing eczema. Gastrointestinal symptoms may involve abdominal pain, vomiting, and diarrhea. Respiratory manifestations include recurrent coughing, stridor, and wheezing (7).

Avoiding nuts is an essential aspect of nut allergy management. However, oral immunotherapy is considered an alternative treatment option (8).

While sunflower seeds are an uncommon source of allergy, some cases of sunflowers-related occupational allergies have been documented. Bird breeders are notably prone to developing allergies to sunflowers (9).
