Health Benefits of Almonds
The medicinal properties of almonds have several uses:
Protecting cardiovascular health. It has been shown that almonds help regulate cholesterol levels, as well as blood pressure, thus reducing the risk of heart disease.1
Strengthening bones and teeth. Almonds are rich in minerals, which support healthy bones and help prevent osteoporosis.
The neuroprotective properties of almonds (both sweet and bitter) are under investigation; some clinical trials have shown sweet almond syrup's effects on reducing ADHD symptoms and improving Alzheimer's disease as well as regular attention spam and memory.2 However, more research is needed to further explore these potential benefits.
Additionally, almonds help strengthen the immune system, protect the body against diseases, and regulate blood sugar, which is beneficial for people with diabetes. Moreover, eating almonds improves human microbiota as well as stimulates bowel movements, thus relieving constipation.3
Interestingly, a study has shown that using grape seed oil and sweet almond oil massage reduces pregnancy edema.4 Likewise, topical use of almond and sunflower seed oils can benefit preterm babies' skin.5
How It Works
The active constituents of almonds are globulins, mainly amandine
and albumin, a group of proteins that plays an important role in liver function, blood clotting, and fighting infection, as well as amino acids, such as arginine, histidine, lysine, phenylalanine, leucine, valine, tryptophan, methionine, and cystine, which are the building blocks of proteins and also regulate key metabolic pathways that are necessary for maintenance, growth, reproduction, and immunity.
A 30 - 40% decrease in heart disease has been observed in those who consume a healthy amount of almonds in their diet.
The skin of almonds is rich in phenolic compounds, including flavanol and flavonol glycosides, as well as anthocyanins, procyanidins, and phenolic acids, all of which possess a strong antioxidant capacity. Research shows these substances have anti-inflammatory properties, relieving gastrointestinal issues and protecting the body against harmful pathogens.
The insoluble fiber present in the skin of almonds is mainly responsible for helping regulate blood glucose levels, reducing cholesterol, and aiding constipation.
Almonds Side Effects
Sweet almonds have not reported side effects and are considered generally safe for human consumption, but unprocessed bitter almonds or unknown varieties of almonds should be avoided, as they contain a chemical called hydrocyanic acid (HCN), or cyanide, which is extremely poisonous. However, bitter almond oil is safe, as the process of extraction eliminates the toxic cyanide, and the final product can be used for flavoring and medicinal purposes.
Almond's nutritional profile is also remarkable: it is an excellent source of minerals, mainly copper, manganese, and magnesium, as well as vitamins E and B2 (riboflavin).The combined action of these compounds have a positive impact on the durability and strength of bones and teeth, as well as on the immune system.
Almonds are also a good source of phosphorus, zinc, calcium, and iron, as well as B-complex vitamins, mainly B3 (niacin) and B1(thiamin). Additionally, almonds provide reasonable amounts of other minerals and vitamins, all of which contribute to their nutritional benefits.
Almonds are low in calories compared with other nuts, but rich in healthy fatty acids, insoluble fiber, and protein. Their daily consumption contributes to increase satiety and reduce food cravings, thus helping weight management.
23 unroasted, whole kernel almonds (one ounce or 28.35 g) amount 164 calories, with 12% and 14% of the daily value for protein and dietary fiber, respectively.

Almond trees are a hardy species, typically grown in expansive orchards. When in bloom, almond trees are a beautiful sight, with light, white to pink flowers adorning their dark brown limbs.
Almonds prefer nutrient rich, deep soils with a good drainage.
The planting location must be in a warm area, with plenty of sunlight, since almond trees are sensitive to cold.
Almonds are commonly propagated using peach seedlings as rootstocks.
Almond trees grow quite large, and at maturity will occupy a space of roughly 20 x 20 feet (6 x 6 m). They are usually planted in rows 22 - 24 feet (6.5 - 6.9 m) wide, with the same spacing between the plants.
Almonds are known for their relatively high drought tolerance, however, a good irrigation system will have a very big impact on yields.
The trees can be grown by simply placing a fresh, unprocessed nut in a sunny location, and they only need maintenance pruning every few years.
Almonds can take up to five years to harvest, which is done by shaking the trees when hulls begin to split. For the amateur home-grower, it's important to pick up the almonds as soon as they're ready so that they don't become a passing bird's lunch.

Almond trees are most commonly found in California and southern Europe along the Mediterranean coastline. They are generally 10 - 20 feet (3 - 6 m) high with thorny dark brown branches, lanceolate leaves, and soft, white flowers. The fruit of the almond, otherwise known as the drupe, is left either shelled or unshelled.
Almond (Prunus dulcis) is one of the 3000 species that, across 100 genera, make part of the large Rosaceae family. Only the Prunus genus comprises over 400 species of both deciduous and evergreen plants, notably the so called "stone fruits", such as cherry (Prunus spp.), prunes (Prunus domestica), and apricot (Prunus armeniaca). All parts of Prunus plants are toxic except the mature fruits.
Varieties and Cultivars of Almond
P. dulcis (alternatively known as P. amygdalus or Amygdalus dulcis) has two main varieties: P. dulcis var. dulcis (sweet almond) and P. dulcis var. amara (bitter almond).
Sweet almonds have many cultivars, being some of the most popular ones: 'Nonpareil', 'Carmel', 'Butte', 'Tuono', 'Padre', 'Mission', 'Monterey', 'Sonora', 'Fritz', 'Price', 'Marcona', 'Ferragnes', and 'Peerless'. The hybrid of 'Tuono' and 'Nonpareil' produces self-pollinating trees.
Sweet almonds are generally more beneficial for oral consumption, as bitter almonds are high in cyanide.
Native to tempered regions of Asia and the Mediterranean - a large territory that includes present-day Turkmenistan, Uzbekistan, Israel, Jordan, Lebanon, and Turkey - almond's history can be traced back to the trade routes of the first civilizations.
It is thought that modern almonds evolved from ancestral species in the Middle East, and were domesticated around 3000 BCE. The almond tree and its nuts have been recorded in Hebrew literature as early as 2000 BCE, and modern cultivars were brought into Greece around 300 BCE. From there, they spread to other areas of the Mediterranean basin and were introduced to North America during the 19th century.
The first European almonds were planted in California as early as 1853, and nowadays “The Golden State" is the largest commercial grower of these nuts, accounting for about 84% of the global production.
An agricultural super-crop in California, almonds contribute $4.3 billion USD per year and create jobs for 104,000 people. As the demand grows, over 900,000 acres (364,217 ha) in California are designated for almond farming.
The historical importance of the almond tree is reflected in many cultural expressions, specially in the Asian countries from where this valuable crop hailed. While in areas of Pakistan, western China, and India, the prayer cap, or topi, is often adorned with patterns that represent single almond blossoms, in Arabia and other Muslim areas the early almond blossoms are seen as a symbol of hope, and in the Hebrew tradition a flowering almond represents God's watchfulness over the creation. To this day, modern English Jews carry branches of flowering almonds into the synagogue on spring festival days.
In Tuscany, almond branches are used as divining rods to locate hidden treasures.
Other Uses of Almond
Cosmetics. The sweet almond oil is used as a fragrance in perfumery, as well as an emollient agent in creams and lotions.
Liquors. Almonds are also used as a flavoring ingredient in Amaretto, a traditional Italian liquor.
Industrial uses. The gum exuded from the almond tree has been employed as a substitute for tragacanth.
