Almond milk has become one of the most sought-after plant-based alternatives to dairy, loved for its mild nutty taste, light consistency and versatility in everything from coffee to smoothies. It is especially popular among those who are lactose intolerant, vegan or simply looking to cut down on dairy consumption. Beyond convenience, many people choose almond milk for its lower calorie count and potential health benefits compared to whole milk. However, like any dietary choice, it is not without its drawbacks.
What are the side effects of almond milk?
Although almond milk offers nutritional benefits, it may not suit everyone. Here are some potential almond milk side effects you should consider:
1. May cause thyroid problems
Almonds contain goitregens. When consumed excessively, these natural compounds can interfere with iodine absorption and disrupt thyroid function. If you have low thyroid function or any thyroid disorders, consider taking almond milk moderately to avoid potential complications.
2. Can trigger nut allergies
Individuals with nut allergies should not consume almond milk, as it is made from almond nuts, which contain proteins like cupin and prolamins that can trigger allergic reactions. If you’re allergic to tree nuts, it’s safer to choose other plant-based milk alternatives, such as oat or coconut milk, to minimise health risks.
3. Can cause digestive discomfort
While homemade almond milk is deemed safe when consumed within its shelf life, store-made milk can trigger gastrointestinal issues. Some people experience gas, bloating or stomach cramps after consuming almond milk.
Potential allergic reactions to almond milk
Here are some of the possible and common allergic reactions to almond milk:
- Skin reactions like itching, hives, redness or eczema flares.
- Oral symptoms like tingling and swelling on the lips, tongue or throat.
- Respiratory problems like a runny nose, coughing, shortness of breath and wheezing.
- Digestive issues like nausea, stomach cramps, diarrhoea and vomiting.
Digestive issues linked to almond milk consumption
Although almond milk is lactose-free and suitable for those with lactose intolerance, it can still cause digestive issues in some individuals. Common problems include bloating and gas from thickeners like guar gum or xanthan gum, nausea or discomfort from flavouring agents and preservatives and stomach cramps or diarrhoea due to carrageenan found in some products. Additionally, the high fibre content in almonds can lead to stomach discomfort in people sensitive to fibre.
Interactions with medications or supplements
Almond milk can interact with certain medications or supplements, such as:
- Thyroid medications: Like other plant-based milks, fortified almond milk may interfere with the absorption of levothyroxine, a common thyroid medication.
- Iron absorption: Phytic acid in almonds can resist the absorption of non-heme iron from plant-based foods. This can be an issue for people relying on supplements or having a vegetarian diet.
- Blood thinners: Almonds contain vitamin E, which can mildly enhance the effect of blood thinners, raising bleeding risk.
Overconsumption risks of almond milk
Excessive consumption of almond milk can lead to several potential health risks, such as:
- Potential kidney issues: Almonds contain oxalates. High intake of almond milk and other oxalate-rich foods can lead to kidney stone formation in some people.
- Blood sugar spikes: Flavoured or sweetened almond milk can be high in added sugars. Overconsumption may raise blood sugar levels, especially in people with diabetes.
- Affects bone health: While fortified almond milk contains calcium, it may lack adequate protein or magnesium compared to dairy milk. Relying solely on almond milk without a balanced diet could affect bone mineralisation and strength over time.
Comparing almond milk with other plant-based milks
Different plant-based milks vary in nutrition, suitability and taste, so it is helpful to compare them to determine which best fits your dietary needs.
