As our community continues to develop and our food becomes more refined, the incidence of allergic diseases appears to be on the rise. Peanut allergy is particularly common. Currently, about 1%-3% of children are affected by peanut allergies.

Genetics play a significant role in peanut allergies. Generally, if a family member has a peanut allergy, a child is more likely to develop one as well. Additionally, a deficiency in vitamin D can increase the risk of peanut allergies among local children.

During adolescence, which is a crucial stage for our immune system development, fluctuations in hormone levels can impact how our immune system functions. Allergic reactions occur when our immune system becomes hypersensitive to specific substances, resulting in the manifestation of allergic symptoms. So, to prevent allergies among adolescents, it's essential to enhance the stability and regulatory mechanisms of our local immune systems.

Recent research published in the New England Journal of Medicine by experts from King's College London suggests that introducing peanuts into infants' diets early can help prevent peanut allergies in the long run. Scientifically feeding children peanuts from infancy until they reach 5 years old can lower the occurrence of peanut allergies among adolescents by 71%.

Early consumption of peanuts, whether through oral or intestinal exposure, can promote immune tolerance and decrease the likelihood of developing peanut allergies. Subsequent studies have further supported the notion that introducing peanuts early can effectively lower the risk of peanut allergies.

Although early peanut consumption can be beneficial for many, it's important to note that not everyone may be suited for it. Those with a personal or family history of peanut allergy should avoid peanuts or seek gradual introduction under medical supervision. Moreover, it's crucial to consider the interplay between peanut allergies and other allergens like allergic rhinitis and asthma, taking a comprehensive approach to managing them.

Peanuts are rich in nutrients, boasting a high protein content second only to soybeans. For every 100g of peanuts, you'll find 25-30g of protein. These nuts are also rich in fats, with 100g containing 44.3g of fat, primarily unsaturated fatty acids. What's more, peanuts are packed with various vitamins including A, E, C, and B, along with carotene, and they're completely cholesterol-free. Additionally, they're a good source of dietary fiber and offer essential trace elements such as calcium, iron, phosphorus, potassium, sodium, zinc, selenium, copper, manganese, and iodine. They're also loaded with nearly 20 different amino acids.

Consuming peanuts in moderation can help lower the risk of metabolic syndrome and prevent cardiovascular and cerebrovascular diseases. It's especially advantageous for heart health.

Apart from individuals with allergies, who should consume peanuts in moderation include:

- Hyperlipoproteinemia: For those who dealing with hyperlipoproteinemia and needing to manage saturated fatty acids and cholesterol intake, peanuts may not be the best choice. They're high in fat and calories, which can pose challenges for this condition.

- Gout: For those dealing with gout, it's wise to steer clear of foods rich in purines. Peanuts, being high in both purines and fats, aren't ideal for aiding uric acid excretion.

- Gallbladder removed: If you've had your gallbladder removed, remember that without its storage function, bile release is altered, affecting digestion and absorption. Given peanuts' challenging digestibility, it's advisable to limit your intake.
