SWEET POTATOES; Favorite Fruit and the Nutrients It Contains

Although they're soft and creamy enough to be put in pies and called dessert, sweet potatoes are also a surprisingly nutritious vegetable.
"Sweet potatoes are high in vitamin A, vitamin B5, B6, thiamin, niacin, riboflavin, and, due to their orange color, are high in carotenoids," said San Diego-based nutritionist Laura Flores. Plus, they're fat-free, relatively low in sodium and have fewer calories than white potatoes — although they do have more sugar.
Sweet potatoes are one of the best sources of vitamin A; a large one contains more than 100 percent of the daily recommended intake, according to the U.S. Food and Drug Administration. Vitamin A is an antioxidant powerhouse, and is linked to anti-aging benefits, cancer prevention and the maintenance of good eyesight, according to the National Institutes of Health.

Although the orange variety is the most common in the United States, sweet potatoes also come in white, yellow, pink and purple varieties, according to the Library of Congress. While the orange and yellow types contain the most vitamin A, the purple sort is an excellent way to get antioxidants, the Cleveland Clinic reports.

BANANA; Favorite Fruit and the Nutrients It Contains

 Bananas are among the most widely consumed fruits on the planet and, according to the U.S.
Department of Agriculture, Americans' favorite fresh fruit. The curvy yellow fruits are high in "potassium and pectin, a form of fiber," said Laura Flores, a San Diego-based nutritionist. They can also be a good way to get magnesium and vitamins C and B6. "Bananas are high in antioxidants, which can provide protection from free radicals, which we come into contact with every day, from the sunlight to the lotion you put on your skin," Flores added.
Flores reported a wide variety of health benefits associated with the fruit. "Bananas are known to reduce swelling, protect against developing type-2 diabetes, aid in weight loss, strengthen the nervous system and help with production of white blood cells, all due to the high level of vitamin B6 that bananas contain," she told Live Science.

WATERMELONS; Favorite Fruit and the Nutrients It Contains

Watermelons are mostly water — about 92 percent — but this refreshing fruit is soaked with nutrients. Each juicy bite has significant levels of vitamins A, B6 and C, lots of lycopene, antioxidants and amino acids. There's even a modest amount of potassium. Plus, this quintessential summer snack is fat-free, very low in sodium and has only 40 calories per cup.
Scientists have taken notice of watermelon's high lycopene levels — about 15 to 20 milligrams per 2-cup serving, according to the National Watermelon Promotion Board — some of the highest levels of any type of fresh produce. Lycopene is a phytonutrient, which is a naturally occurring compound in fruits and vegetables that reacts with the human body to trigger healthy reactions. It is also the red pigment that gives watermelons, tomatoes, red grapefruits and guavas their color.
Lycopene has been linked with heart health, bone health and prostate cancer prevention. It's also a powerful antioxidant thought to have anti-inflammatory properties, according to Victoria Jarzabkowski, a nutritionist with the Fitness Institute of Texas at The University of Texas at Austin. 

To really maximize your lycopene intake, let your watermelon fully ripen. The redder your watermelon gets, the higher the concentration of lycopene becomes. Beta-carotene and phenolic antioxidant content also increase as the watermelon ripens. Nevertheless, "All parts of the watermelon are good. There are a lot of nutrients throughout," said Jarzabkowski. This includes the white flesh nearest the rind.

ORANGES; Favorite Fruit and the Nutrients It Contains

Sweet, juicy oranges make a delicious and healthy snack or addition to a meal. A whole orange contains only about 85 calories and has no fat, cholesterol or sodium. And, of course, "oranges are well known for their vitamin C content," said Laura Flores, a San Diego-based nutritionist.
Oranges may boost your immune system and improve your skin; they also aid with heart health, cholesterol levels and other issues. Oranges may additionally help reduce the risk of respiratory diseases, certain cancers, rheumatoid arthritis, ulcers and kidney stones.
Orange juice is also packed with nutrients but does not contain the fiber of a whole orange. Orange pith, the white substance between the peel and the flesh, is high in fiber. Furthermore, it is easy to consume more calories when drinking orange juice than when eating an orange, warns the Centers for Disease Control.

PINEAPPLE; Favorite Fruit and the Nutrients It Contains

Spiny on the outside, sweet on the inside, pineapples are one fantastic fruit. Pineapples are members of the bromeliad family, and one of the few bromeliads to produce edible fruit, according to the biology department at Union County College. The fruit is actually made of many individual berries that fuse together around a central core. Each pineapple scale is an individual berry.
Pineapples’ nutritional benefits are as fascinating as their anatomy. “Pineapples contain high amounts of vitamin C and manganese,” said San Diego-based nutritionist Laura Flores. These tropical treats are also a good way to get important dietary fiber and bromelain (an enzyme).
“As well as having high amounts of manganese, which is important for antioxidant defenses, pineapples also contain high amounts of thiamin, a B vitamin that is involved in energy production,” Flores said. 
For all its sweetness, one cup of pineapple chunks contains only 82 calories. Pineapples are also fat-free, cholesterol-free and low in sodium. Not surprisingly, they do contain sugar, with 16 grams per cup.

SOME FAVOURITE FRUITS AND THEIR NUTRITIONAL VALUES AND BENEFITS

APPLE; Favorite Fruit and the Nutrients It Contains

Let’s face it, our food preferences are based on taste, not nutrition, which is why fruit is such a great food. Fruit tastes sweet and interesting. They have an agreeable texture, crunchy like apples, smooth like a peach, and juicy like an orange. And most fruits are surprisingly nutritious. Though not as nutrient-dense as vegetables, fruits are an important source of vitamins, minerals, and enzymes. Some fruits are more nutritious than others, but with fruits, as with vegetables and grains, variety is the spice of life. Nutrients that one fruit lacks, another fruit provides. Fructose is the principle sugar in most fruits, though sucrose is the principle sugar in others, such as oranges, melons, and peaches. Fructose is absorbed slowly into the bloodstream, so fruit gives you energy without triggering the ups and downs of the insulin cycle.

1. Apple. An apple a day may not keep the doctor entirely away, but apples are nutritious, convenient, and always available. Apples get an A+ in fiber content, since they contain a lot of the soluble fiber, pectin, that helps to lower cholesterol. They also contain some cancer-fighting flavenoids. Eating a whole apple is more nutritious than drinking apple juice, since the fiber, vitamins, and minerals may be processed out of the juices. When the flesh of an apple turns brown, it means some of the nutrients have oxidized and are lost. To get the best that any fruit has to offer, eat it fresh. Apples are one of the healthiest foods a person can eat. They are high in fiber and vitamin C, and they are also low in calories, have only a trace of sodium, and no fat or cholesterol.
   "Apples are high in polyphenols, which function as antioxidants,” said Laura Flores, a nutritionist based in San Diego. “These polyphenols are found in both the skin of the apples as well as in the meat, so to get the greatest amount of benefits, eat the skin of the apple."
   All of these benefits mean that apples may mitigate the effects of asthma and Alzheimer's disease, while assisting with weight management, bone health, pulmonary function and gastrointestinal protection.
   
   
   Often called a "miracle food" and "nutritional powerhouse," an apple a day really may keep the doctor away. Here are the nutrition facts from the U.S. Food and Drug Administration, which regulates food labeling through the National Labeling and Education Act:

   Health benefits

   Apples are loaded with vitamin C. Almost half of an apple's vitamin C content is just under the skin, so it's a good idea to eat apples with their skins. Flores said that this is also where apples' fiber is found. Apples contain insoluble fiber, which provides bulk in the intestinal tract. The bulk holds water that cleanses and moves food quickly through the digestive system.
   According to Flores, "Regular intake of apples has been shown to have cardiovascular benefits. [This is due to] two properties of apples: the fiber that they contain and the polyphenols that are found in high amounts."
