Citrus fruits and berries may be especially powerful for preventing disease. A 2014 study ranked “powerhouse” fruit and vegetables by high nutrient density and low calories. Lemons came out top of the list, followed by strawberry, orange, lime, and pink and red grapefruit.
Some of the healthiest fruits include pineapple, apples, blueberries, and mangos. You should eat three servings of fruit a day as part of a healthy diet. Eating fruit improves heart health, reduces inflammation, and boosts your immune system.
1. Apples. One of the most popular fruits, apples are chock-full of nutrition. They're rich in both soluble and insoluble fiber, such as pectin, hemicellulose, and cellulose.
While bananas might be the first fruit to come to mind, watermelon actually reigns supreme when it comes to potassium. In just 2 wedges, or about 1/8th of a melon, you'll get 640 mg of potassium, or about 14% DV. Watermelon is also a great source of vitamin C, vitamin A, and the antioxidant lycopene.
Apples vs oranges
A clear winner comes forth if you're trying to boost your immune system before the winter hits. While apples contain more fiber, an important nutrient that aids in healthy digestion and lowering cholesterol, oranges provide more vitamins and minerals including the ever-powerful vitamin C.
Lemons. Lemons have been widely regarded in the health industry as the world's healthiest food. The sour fruit is an alkalising powerfood; they have strong anti-inflammatory qualities and can even help to inhibit the growth of cancer cells.
They're full important nutrients, but eating too many could end up doing more harm than good. Too much of any single food may contribute to weight gain and nutrient deficiencies. One to two bananas per day is considered a moderate intake for most healthy people.
Adults should eat at least 1 ½ cups of fruit every day. However, a “fruitarian” diet, in which you eat almost nothing but fruit, can keep you from getting enough nutrients from other foods. Experts recommend that 25%-30% of your diet be made up of fruit.
Bananas.
Bananas are rich in magnesium and have been found to significantly increase melatonin. They're also a good source of carbohydrates to fill you up, making this peel-and-eat snack another easy food to enjoy before bed.
Try not to mix acidic fruits, such as grapefruits and strawberries, or sub-acidic foods such as apples, pomegranates and peaches, with sweet fruits, such as bananas and raisins for a better digestion. However, you can mix acidic with sub-acidic fruits. For a similar reason, you should not mix guavas and bananas.
Increased fruit intake can also help lower blood pressure and reduce oxidative stress, which may decrease the risk of heart disease (31). Eating more fruits and vegetables is also associated with improved blood sugar control in people with diabetes ( 32 ).
Eat 2 to 4 servings of raw fruit or vegetables per day, especially carrots, sweet potatoes, spinach, kale, bell peppers, papaya, mangos, oranges and berries. Raw fruits and vegetable retain full antioxidant strength and the brighter the produce the better.
Strawberries, blueberries, blackberries, and raspberries are jam-packed with important nutrients that play a central role in heart health. Berries are also rich in antioxidants like anthocyanins, which protect against the oxidative stress and inflammation that contribute to the development of heart disease ( 9 ).
Why is Kiwi fruit known as a nutritional powerhouse? Kiwi fruit stands number one in nutrient content compared to 27 other fruits. It is packed with twice the amount of Vitamin C — compared to oranges (per 100 mg) — and has twice the amount of nutrients — compared to apples (per 100 mg).
Banana health benefits far outweigh those of the apple. That's because they have many more vitamins and nutrients than their round counterparts. Bananas have twice as many carbohydrates, 5 times as much Vitamin A and iron, and 3 times as much phosphorus as apples.
Apples contain slightly more fiber than bananas, a nutrient that supports gut health and promotes satiety. The skin contains most of that fiber, which is why it's beneficial to eat apples as they're found in nature rather than peeling them.
