Marmalade is a sweet product that, if properly composed, can be beneficial to the body. Traditionally, it was made from fruit juices or purees, evaporating the liquid to a thick, viscous consistency. Most often, fruits rich in pectin were used for this, in particular apples, apricots, quinces or black currants. Over time, the recipe for marmalade became more diverse: citrus juices, gelatin, pectin or agar-agar were added to the composition for better gelling.
Modern marmalade production usually involves mixing fruit puree or juice with sugar or molasses, then evaporating the liquid and adding thickeners. In mass production, artificial colors and flavors are often used to give the product a bright appearance and rich taste. At the same time, marmalade made from natural juices and natural colors without chemical additives is considered the most useful.
The benefits of marmalade are largely due to the pectin found in the fruit. This substance helps lower "bad" cholesterol levels, normalizes metabolism, and supports the functioning of the gastrointestinal tract. Pectin also helps remove heavy metals from the body and has a positive effect on the condition of the skin.
Agar-agar, which is obtained from seaweed, also has beneficial properties. It improves liver and stomach function, helps eliminate toxins, and contains iodine. That is why marmalade based on agar-agar can be useful for people with thyroid disorders, provided that it is consumed in moderation.
In addition, marmalade can support joint health by helping to strengthen cartilage. Due to its gelling components, it is sometimes recommended as a light dessert during the recovery period after physical exertion.
At the same time, the harm of marmalade is most often associated not with the product itself, but with its composition. Artificial dyes, flavors and chemical additives used in mass production can cause allergic reactions or negatively affect health. Therefore, when choosing marmalade, you should pay attention to the composition and give preference to natural options with a minimum amount of sugar.
Even agar-agar-based marmalade requires moderation, as excess iodine can be harmful. People with diabetes are advised to choose special marmalades without sugar or with sugar substitutes.
