The practice of consuming almond soaked water has gained popularity. This process, typically performed overnight, softens the almonds and changes the composition of the water. This article explores the scientific mechanisms behind almond soaking and evaluates whether drinking the resulting water offers any distinct nutritional advantages.
The Science of Soaking: Reducing Phytic Acid
Almonds, like many seeds, contain phytic acid (or phytate), which is concentrated in the almond skin. Phytic acid acts as a storage form of phosphorus, but it can bind to essential minerals like zinc, iron, and calcium, potentially inhibiting their absorption by the body. Soaking is traditionally done to neutralize this compound.
Soaking is theorized to activate the naturally occurring enzyme called phytase within the almond, which begins to break down the phytic acid into more digestible components. This process is thought to improve the bioavailability of the almond’s own nutrients. However, scientific evidence on whole almonds shows that cold soaking for standard durations, such as 12 hours, results in only a minimal reduction in phytic acid levels. The primary benefit of soaking is therefore often limited to softening the nut’s texture rather than dramatically altering its nutritional profile.
Nutritional Content of Almond Soaked Water
When almonds sit in water, water-soluble compounds begin to leach from the nut and its skin into the surrounding liquid. This includes trace amounts of water-soluble B vitamins, such as folate, some minor minerals, and small amounts of protein and starches from the nut’s surface.
The water also becomes infused with phenolic compounds concentrated in the almond’s brown skin. These compounds, which include tannins, are responsible for the slight bitterness that can be noticeable in the soaking water. While these substances are beneficial in higher concentrations, the amount transferred to the water during a typical overnight soak is very low compared to the nutrients contained within the almond kernel itself or in commercially prepared almond milk.
Safety and Preparation Recommendations
A primary concern when considering drinking almond soaking water is the potential for microbial growth. Almonds are low-moisture foods, but when submerged in water, they create an ideal environment for bacteria to multiply. Pathogens such as Salmonella and E. coli can rapidly increase in population after about eight hours of soaking at warm temperatures.
To mitigate this risk, almonds should be soaked in clean, filtered water, and the container should be kept in the refrigerator. The soaking duration should be limited to a maximum of 8 to 12 hours. It is recommended that the water be consumed immediately after draining due to the presence of leached tannins and potential microbial contamination.
Is Drinking Almond Water Beneficial?
The benefits of drinking almond soaked water are minimal and often overstated. The trace amounts of leached vitamins, minerals, and antioxidants do not constitute a significant addition to a person’s daily nutrient intake. The main nutritional benefit of soaking is the softening process, which can make the almond more palatable and potentially easier to digest for some individuals.
While the practice is generally safe if proper refrigeration and hygiene protocols are followed, the water is essentially a very dilute nutritional liquid. Drinking almond soaked water provides minimal specific advantage. The greatest health benefits come directly from consuming the soaked almond, not the water used in the process.
