Raisins (dried grapes) possess the ability to enhance a variety of foods – breakfast cereals, salads, and desserts are just a few examples. However, these tiny dried fruits also boast of a rich nutritional profile. Raisins not only are delicious on-the-go snacks to comfort your sweet cravings but they are also powerhouses of nutrients. This article delves into the many health benefits of raisins, underlining their importance in your diet.
Raisins flaunt an extraordinary nutritional profile with a veritable treasure trove of benefits. The composition of these dried fruits includes a dense supply of nutrients, notably potassium, magnesium, and calcium. Meanwhile, bioactive phytochemicals and dietary fibre lend their rich presence as well, which contributes to overall well-being. Additionally, raisins have a glycemic index ranging from low to moderate; this implies that they undergo slow absorption in the body and consequently prevent sudden spikes in blood sugar levels. This makes it particularly good for people with diabetes.
Health Benefits of Raisins
1. Good for the digestive system
Raisins contain certain phytochemicals like triterpenoid and tartaric acid. Triterpenoids are important nutrients that aid in digestion by their action on food breakdown and digestive processes. The different types of triterpenoids include, oleanolic acid, oleanolic aldehyde, betulin, and betulinic acid. Similarly, tartaric acid also aids in the digestive process. These phytochemicals, along with the high content of dietary fibre in raisins, make this dried fruit an excellent choice to eat (in moderation, of course) for better digestion.
2. Good for eyesight
Research has shown that regular consumption of raisins can help prevent vision loss and other eye-related issues. This is because raisins are rich in antioxidants, which reduce oxidative damage caused by reactive oxygen species (ROS) in the body. These antioxidants, namely vitamins A and C, work together to protect the eyes from degenerative processes caused by aging.
Moreover, raisins contain a significant amount of phenolic compounds, which are responsible for their anti-oxidative properties. Interestingly, dark raisins have a higher concentration of these compounds compared to golden or Muscat raisins. This makes dark raisins an even better option for those looking to improve their eyesight.
3. Manage hypertension
Additionally, studies indicate that regular consumption of moderate portions of raisins may aid in the management of hypertension (high blood pressure). This is attributed to their rich mineral content, notably potassium, which is known to reduce elevated blood pressure levels. Moreover, through its interaction with nitric oxide produced within cells—the presence of phenolic compounds within these dried fruits further contributes to lowering overall cardiovascular stress by lowering systemic arterial pressure. Further aiding this process, the phenolic compounds, found in raisins, act upon internally formed nitric oxide, to promote cellular health and balance throughout our cardiovascular system.
4. Promote good heart health
Raisins may also aid heart health by reducing cholesterol levels. Furthermore, their consumption mitigates the presence of pro-inflammatory markers, such as TNF (tumor necrosis factor-alpha), thus minimising potential cardiac damage. Additionally, due to the presence of dietary fibre, phytochemicals and antioxidants within raisins, lipids/lipoproteins undergo effective metabolism—a process critical for cardiovascular well-being, and thus, tissue damage can be actively prevented. All these, in turn, promote good heart health.
5. Promote strong bones
Raisins are packed with calcium, the most important mineral for bones. In addition, raisins contain magnesium, potassium, and vitamin D – nutrients important for maintaining bone health. The calcium in raisins increases bone density, while magnesium makes the bones stronger and lowers the risk of fractures. Raisins also contain boron, a mineral required for the absorption of calcium and magnesium, which promotes strong bones.
6. Immunity booster
A strong immunity comes in handy when our body is fighting viral infections like SARS-CoV-2 (coronavirus). Raisins have a significant amount of vitamin C, minerals, polyphenols, as well as antioxidants that may help improve immunity and fight infections that occur due to virus or bacteria.
7. Increases iron level in blood
Iron is an important element that is required to make red blood cells, which further carry oxygen throughout the body. Iron deficiency might lead to various blood-related diseases like anaemia. Raisins contain a good amount of iron, which can be beneficial for people with such health conditions. Half a cup of raisins usually provides 7% of the daily recommended value of iron. Eating a handful of soaked black raisins, particularly in the morning, may help to curb anaemia.
