Grapefruit as a Support in Weight Loss
Grapefruit is a widely consumed food product known for its bitter or sour taste and high content of bioactive substances. It is very often mentioned as an ally in the fight against excess fatty tissue. The biologically active substances in grapefruits very often interact with other supplements or medicines, enhancing or obscuring their effects. Therefore, their use should be considered, their potential side effects should also be taken into account. Grapefruit is rich in vitamin C (about 30-35 mg/100 g of product), and the daily requirement for this vitamin is met by consuming the entire fruit (about 260 g). Grapefruit also contains many compounds that have a positive effect on the human body, such as flavonoids, coumarins, monoterpenes and carotenoids, pectin and fiber. Grapefruit is also used in the treatment of diabetes, as it increases insulin levels and lowers blood glucose levels. In addition, it eliminates yeast infections, stimulates metabolism, lowers cholesterol levels in the blood and provides effective protection against free radicals. Grapefruits are also used in the cosmetics industry, and their extract is often found in skincare products, especially for sensitive skin that is prone to rosacea and pigmentation. The recommended dose of grapefruit is half a fruit, but it can also be consumed in the form of a refreshing juice.
Bitter orange and its marvelous extract
Bitter orange is a perennial plant native to Southeast Asia. Its extract is a source of tyramine derivatives such as octopamine and synephrine, as well as other bioactive phytochemical compounds. Bitter orange is used to reduce excess body weight by inhibiting appetite and stimulating metabolism. The combination of octopamine, synephrine, and caffeine along with polyphenols from green tea activates the process of lipolysis, releasing fatty acids, which increases energy expenditure. Bitter orange, known as Citrus auranitum, also has antidepressant, anxiolytic, calming, and relaxing effects. It is also used in cases of diabetes, fungal infections, and digestive problems. The recommended daily dose of the orange extract (20%) is 25-75 mg in two doses. This dose corresponds to the daily dose of synephrine, which should be taken in amounts of 10-30 mg. In terms of contraindications, attention should be paid to high blood pressure and medications from the group of statins, whose action can be modified by compounds in the extract. The alkaloids contained in bitter orange can inhibit the action of cytochrome P450, which increases the blood concentration of the drugs. Excessive consumption of bitter orange can cause high blood pressure and head and abdominal pain.
The prickly pear fruit – a cactus association
The prickly pear, also known as cactus pear, is a plant whose fruit is referred to as cactus fruit. This fruit comes in a variety of colors, from white to yellow to red. The color is inextricably linked to the type of pigment it contains. Betanin and indicaxanthin are natural alkaloid dyes used in sugar and cosmetics. The primary health benefits of this plant are that it alleviates the symptoms of diabetes and lowers cholesterol levels in the blood. The recommended daily dose of cactus fruit is typically 200g, which is equivalent to the weight of one fruit. Other varieties of cactus fruit are also available on the market, such as the fig cactus fruit, which can help lower blood sugar levels by stimulating the pancreas to produce insulin. The fruits of each type of cactus fruit are characterized by a high antioxidant potential and a significant amount of dietary fiber, making them a great addition to a healthy diet. In addition to the health benefits, cactus fruit can also be used in cosmetics for the production of anti-wrinkle creams and protective products against UV radiation.
