Here we would like to introduce to you the fruits that you should pay attention to when you have the following diseases. You mustn't be careless! Acute nephritis: People with poor kidney function or edema who need to avoid salt should not eat bananas, as bananas contain a relatively high amount of sodium, which can aggravate edema and increase the burden on the heart and kidneys. Patients with heart failure and severe edema should avoid eating fruits with high water content such as watermelon, pear and pineapple, as excessive water can aggravate the condition of heart failure and edema. Patients with hypertension and arteriosclerosis should consume fruits rich in vitamin C, such as hawthorn, jujubes and oranges, which have the effects of lowering blood pressure and alleviating arteriosclerosis. Patients with myocardial infarction and stroke: It is advisable to consume fruits that aid digestion, such as watermelon, banana, orange and peach. It is not advisable to eat fruits such as persimmons, apples and lotus seeds, as they contain tannic acid which has astringent effects and can easily cause constipation, worsening the condition. Patients with coronary heart disease and hyperlipidemia should consume fruits such as tangerines, pomelos, hawthorns, peaches and strawberries, as these fruits are rich in vitamin C and niacin, which can help lower blood lipids and cholesterol. Patients with respiratory tract infections, especially those with sore throat, cough and excessive phlegm, are advised to consume fruits such as pears, loquats, oranges, pomelos, apricots and Luo Han Guo, which can help dissolve phlegm, moisten the lungs and relieve cough. For patients with fever: It is advisable to consume fruits such as pears and tangerines, which have the effects of quenching thirst, reducing fever and detoxifying. Because patients with fever sweat a lot, pears, oranges and the like contain sufficient water and potassium, which are more beneficial to them. People with a hot constitution: It is advisable to eat fruits with a cold nature such as pears, bananas and watermelons. It is not advisable to eat fruits that are warm in nature, such as grapes, oranges, jujubes and cherries.
