Vitamins of the kiwi
Eating two Jingold kiwis a day allows you to meet your daily requirement for vitamin C, i.e. 80 mg in adult women and 90 mg in adult men (reference values for the EFSA 2019 diet). The amount of vitamin C contained in 100 g of Jingold green kiwi is, in fact, equal to 85 g, higher than that contained, for example, in oranges (49 mg in 100 g of food) or lemons (50 mg in 100 g).
- Vitamin C is essential for the health of our body as it performs several important functions, first of all being among the main compounds with antioxidant activities. In addition, it helps to increase the absorption of iron in vegetables (not haem) and can affect the absorption of calcium, factors that are extremely important for those who follow a plant-based diet.
- Recent research has shown that kiwis, especially the gold variety (Jingold gold kiwi), can increase the absorption and retention in the body of essential minerals in the diet, especially iron, calcium, phosphorus and magnesium. This role is also played by vitamin E, also contained in Jingold kiwis (in the seeds), although in lower quantities than vitamin C.
In addition, two Jingold kiwis per day (about 150 g) meet almost 100% (86%) of the estimated average daily requirement (AI) for the Italian adult population of another important micro-nutrient: vitamin K (EFSA 2019).
- Vitamin K is involved in blood clotting processes and has the characteristic of being fat-soluble, that is, it dissolves in fats.
Therefore, to absorb it, it is always necessary to associate it with a fat source from a food, such as dried fruit (walnuts, almonds, hazelnuts, pistachios, etc.) or whole yoghurt.
Mineral salts of the kiwi
The Jingold kiwi contains, in addition to vitamins, also many important mineral salts: potassium, magnesium, phosphorus and iron.
- Potassium, in particular, acting in synergy with vitamin C and the polyphenols contained in Jingold kiwis, contributes to the health of the arteries by reducing the risk of atherosclerotic plaque formation and decreasing the triglyceride levels in the blood.
- The potassium content of Jingold kiwis, moreover, is higher than that of bananas: 600 μg in 150 g of fruit, while bananas provide 525 μg in the same amount.
Effects of the kiwi on the heart and on blood pressure
The data available to date, taken from authoritative scientific studies, show that the daily consumption of kiwi is related to the improvement of lipid profiles in the blood, thus reducing cardiovascular risk.
- Even more encouraging results were obtained with the gold kiwi variant: the intake of two gold kiwis every day for six weeks led the overweight and obese patients subject of the study to a greater reduction in fat mass, an improvement in inflammatory parameters and cardiovascular risk indicators.
- A further study showed that in men and women with moderately elevated blood pressure, the consumption of three kiwis per day was associated with a lower systolic and diastolic blood pressure in 24 hours compared to the consumption of one apple per day.
For all these reasons, Jingold kiwis should be considered as part of a natural and effective dietary strategy to address some of the main concerns for health and well-being around the world, as they are useful in the slimming diet thanks to their laxative and anti-inflammatory properties, as well as for their protective function of the cardiovascular system given by vitamins and minerals contained in the fruit.
