Avocados are a very healthy fruit, they are rich in fiber and good fats that help lower bad cholesterol. Most foods will cause weight gain if you eat too much, but avocados are more likely to gain weight than other fruits. An average avocado contains about 227 calories, so eat only 1/5 to maintain weight. The average woman needs 2,000 calories per day, while men need 2,800 calories, so just 2 avocados make up about a quarter of the calories the average person needs.
Carrots are loaded with vitamins, minerals, and fiber that are very healthy. But in carrots contains beta-carotene, a molecule that creates a bright orange color, so when eating a lot of carrots, the skin color can change. Carotenemia (too much carotene) leads to yellow or orange skin, especially in the palms, soles of the feet, knees and the nose area. Although carotenemia occurs mainly in infants when too much pureed carrots are fed, it can also occur in adults. However, a cup of chopped carrots has about 15mg of carotene, so you need to eat half a cup of chopped carrots every day for several months before your skin can change color. Although carotenemia looks very dangerous on the surface, the disease is not dangerous and easy to cure.
Bananas contain a lot of nutrients and fiber that are very healthy, but eating too much is not good either. Unripe bananas can cause constipation because they contain a lot of starch, which is difficult for the body to fully digest. Bananas also contain a lot of pectin fiber that draws water from the gut and makes you more constipated if you become dehydrated.
Bananas are classified as a “medium” glycemic food, which means they have a glycemic index high enough to cause some fluctuations in blood sugar. Eating more foods with relatively high blood sugar levels can increase your risk of type 2 diabetes or heart disease and make it harder to control your weight. Bananas are very nutritious and great, but also have a glycemic index high enough to cause some fluctuations in blood sugar.
Apples are an excellent source of both soluble and insoluble fiber. A medium-sized apple contains 4 to 5 grams of fiber, with most of which is cellulose (cellulose). Insoluble cellulose is most concentrated in the apple core. In contrast, the soluble pectin fiber is found mainly in the apple peel. Apples are among the fruits with the most fiber.
Eating too much apples can cause constipation and negatively affect the digestive system. Insoluble fiber draws water out of the large intestine, which can cause the mucous membranes to become too dry when there isn’t enough water. The dry mucous membrane creates friction against waste instead of providing the usual lubricating oil. When the intestinal tract is not working properly, it can lead to gas, abdominal pain and slow digestion. To reduce the risk of constipation, drink plenty of fluids while eating foods high in fiber.
Apples are also rich in fructose – also known as fruit sugar – which is often converted into glucose and covered by your small intestine. However, eating too much apples produces undigested fructose in the large intestine where it feeds the beneficial bacteria. Intestinal bacteria ferment fructose, producing a lot of gas and leading to gas, abdominal pain, and diarrhea.
Tuna is a widely eaten fish, but canned tuna is often the “richest” source of mercury in any food. Natural bacteria absorb mercury and convert it into methylmercury, introducing it into the food chain. Small fish consume or absorb methylmercury and are eaten by larger fish. However, instead of breaking or dissolving, mercury builds up in the food chain. Mercury is odorless and invisible to humans. However, when it enters the body, it acts as a toxin that interferes with the brain and nervous system, and mercury exposure can be especially harmful for young children and pregnant women. The growing child’s brain absorbs nutrients very quickly. Mercury adversely affects that absorption, causing growth retardation. In infants and fetuses, high doses of mercury can lead to cognitive difficulties, cerebral palsy, deafness, and blindness.
