Introduction:

Pine nuts are being consumed in the Mediterranean region for over 2000 years. Commercial pine nuts are largely obtained from Pinus pinea. However, seeds from other plants such as Pinus koraiensis and Pinus gerardiana are also eaten worldwide.¹ The composition of pine nuts varies from species to species and depends on the climatic condition and geographical location. They are a rich source of nutrients and might be beneficial for human health in various aspects.¹ Detailed description is given in the following sections.

Potential Uses of Pine Nuts for Overall Health:

The composition and the nutrients present in it might change depending on the geographical location and climatic condition.¹ However, they do contain vitamins, minerals and various other compounds which might aid human health. Some of the potential health benefits of pine nuts are as follows.

1. Potential uses of pine nuts for cholesterol:

An animal study showed that pine nuts might have the potential to lower lipid levels in the blood. It was also stated that pine nuts might also affect the metabolism of lipoprotein. Pine nuts are rich in nutrients, and vitamins with less cholesterol.³ However, more studies on humans are required to prove these possible effects.

2. Potential uses of pine nuts for weight management:

Peanuts are a rich source of minerals, proteins, and vitamins. Regular consumption or including peanut in the diet reduce the food intake. Few studies showed that pea nuts may maintain proper weight and may control the blood sugar levels in the body. However, further research is required to claim that peanuts are in weight management.³

3. Potential uses of pine nuts for the heart:

A study showed that eating pine nuts might help reduce the level of fat in the blood and may also decrease the incidence of atherosclerosis (deposition of fat material in the human body) and coronary heart diseases. Pine nuts also contain flavonoids and consumption of peanuts might help reduce the risk factors of heart diseases. It might also promote the relaxation of blood vessels and the free flow of blood. However, kindly ensure that you consult a doctor for heart conditions to receive proper treatment. Do not self-medicate.⁴

4. Potential uses of pine nuts for blood pressure:

A few studies have shown that the potential use of pine nuts for heart diseases might be due to its possible effects on the blood vessels. Pine nuts might help reduce systolic blood pressure. It might also help improve the endothelial function (lining of blood vessels), may reduce the plasma viscosity (allows better blood flow) and may reduce the plasma fibrinogen (a factor causing blood clots). All these factors may help in controlling blood pressure.³ However, consult a doctor in case of high blood pressure and do not self-medicate.

5. Potential uses of pine nuts for diabetes:

Researchers have noted that pine nuts extracts might have the potential to lower blood glucose levels. This activity might be due to the presence of proteins, vitamins, and antioxidant activity in pine nuts. However, these effects need to be further evaluated by conducting more studies. Furthermore, conditions such as diabetes need to be diagnosed and treated properly by a doctor. Kindly consult a doctor and do not self-medicate.³

6. Potential uses of pine nuts for the liver:

It was seen in certain animal studies that pine nut extracts might help improve liver function tests. This might be due to the antioxidant activity of pine nuts. There seemed to be an improvement in the structure of liver cells on the administration of pine nut extract too.³ However, these effects need to be evaluated and consulted with a doctor in case of liver infection and not self-medicate.

7. Potential uses of pine nuts for the kidney:

An animal study showed that protection of the glomeruli (Cleaning units of kidneys) and a reduction in inflammation might be due to the administration of pine nuts. This might be potentially due to the reduction of oxidative stress by the antioxidant property of the pine nuts. Therefore, pine nuts might help protect the kidney and might exhibit a reno-protective property.³

Though there are studies that show the potential uses of pine nuts in various conditions, these are insufficient and there is a need for further studies to establish the true extent of the benefits of pine nuts on human health. 

From what I have seen, pinolenic acid (PNLA), derived from pine nuts, may show benefits as a dietary supplement for addressing chronic inflammatory and immune diseases. It exhibits potential benefits in managing these conditions and may serve as a valuable addition to a person’s nutritional regimen.

How to Use Pine Nuts?

Pine nuts can be used in the following ways:

• Raw
• Roasted
• Breads
• Cakes
• Cookies
• Candies
• Sauces
• Meat dishes¹

You must consult a qualified doctor before taking pine nuts in large amounts. Do not discontinue or replace an ongoing treatment of modern medicine with an ayurvedic/herbal preparation without consulting a qualified doctor. 

Recently, I stumbled upon a study that shows that pine nuts might trigger the release of gut hormones involved in bringing satiety, such as cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1). This may result in a decrease in appetite and food intake, suggesting that pine nuts might act as a natural appetite suppressant.

Side Effects of Pine Nuts:

The most common side effects of pine nuts are:

• Pine mouth syndrome: Bitter or metallic taste in the mouth after eating pine nuts is called pine mouth syndrome. It can be caused by the consumption of both raw and roasted pine nuts. Usually, the symptoms of this condition go away on their own (self-limiting) and they do not have any adverse effects on health.¹
• Allergies: Pine nuts can cause allergic reactions in some people. Some of the most common symptoms are:
• Anaphylaxis (a severe allergic reaction that can also lead to death)
• Urticaria (red bumps or rashes on the skin)
• Angioedema (swelling of face, nose, throat, etc.)

• Laryngeal edema (swelling of the throat) ¹

Precautions to Take with Pine Nuts:

One should confirm if it is safe for them to eat pine nuts before eating them. Ensure that you are not allergic to pine nuts, as allergic reactions can be serious and might also lead to death¹. You should be extra cautious while giving it to children as they might be allergic to them.

Interactions with Other Drugs:

It is hypothesised that some medicines like those given for controlling blood pressure (ACE inhibitors and vasodilators) might enhance the severity of anaphylactic reactions to pine nuts. Therefore, you should consult a doctor and confirm if it is safe for you to eat pine nuts before eating pine them, especially if you are taking any medication.¹
