Бананы полезны?

Bananas are a great snack food. They come perfectly packaged in a single serving size. They taste good raw, cooked, in bread or over cereal. They have a lot of great nutritional value.
But… bananas can be hard on your body. Eating bananas comes with risks to your heart and waist line. There are even commonly prescribed medications that you should never take and then eat bananas. Bananas can even cause severe allergic reactions.
In fact, you may never eat another banana after reading this.

Not Such a Diet Food
Bananas have lots of good nutrients but they are not a diet food. Bananas are higher in calories than other fruits – at about 105 calories – and they have less fiber, so you won’t feel full as long.
A banana might be a good snack, but for calorie counters, there are better snacks out there. They are mid-level on the glycemic index, so diabetics may want to avoid them.

Migraines
If you have allergies to aged cheeses like blue cheese or parmesan, you may have a sensitivity to tyramine. Tyramine is naturally found in protein rich foods.
If you do eat bananas, make sure that every stringy fiber is removed. Banana peels are higher in tyramine and are a snack in some countries. If you travel, be aware of banana peels in your meals!
Bananas are full of potassium and that is good for your heart, right? Read on.

Too Much Potassium
Bananas are good for your heart in small doses. If you eat too many bananas, you can develop hyperkalemia. This means you have too much potassium in your blood.
Hyperkalemia can lead to irregular heartbeat, muscle weakness, and temporary paralysis. Most people won’t eat enough bananas to get to hyperkalemia. If you have kidney disease to other diseases that come with an elevated potassium blood level or you are taking potassium supplements, you may be at risk.

Not A Good Breakfast
If you feel sleepy after your morning banana, you are feeling the effects of tryptophan. This is responsible for the after-turkey dinner sleepies.
Tryptophan slows down mental processes and reaction time. Add in the muscle relaxation from all the magnesium in bananas and you have a prescription for a great nap.
Try a banana at bedtime instead of on your morning cereal.
Make sure to brush our teeth afterwards, though. Bananas can be hard on your teeth.

Bananas and Tooth Decay
Bananas can be very healthy for teeth. The calcium and vitamin D make for stronger bones and enamel.
The problem comes from letting the starch and sugars stay on your teeth for a long time. Eating a lot of bananas can temporarily change the pH level in your mouth and this can erode enamel.
Eat a banana but make sure you brush your teeth afterwards to avoid damaging your teeth! But don’t let bananas get on your nerves…

Nerve Damage
If you eat too many bananas and are taking a lot of vitamin B6, you can damage your nerves. You need to take more than 500 milligrams of B6 to reach that level.
You’d pretty much have to eat an entire bunch of bananas in one sitting, but if you are a banana-phile, it could happen.
Can a banana be responsible for your runny nose?

Allergies
People can be allergic to bananas. If you have ragweed allergies, you are probably allergic to bananas. Just handling them can bring on symptoms.
If you can’t eat avocados, kiwi fruit, tomatoes, bell pepper or potatoes without getting an itchy mouth or wheezing, you should eat bananas either.
Bananas contain proteins that are very similar to natural latex. If you are sensitive to latex, you could be sensitive to bananas as well.

Bananas May Not be Safe for Babies
A hazardous part of allergies is anaphylactic shock. It is a potentially fatal condition and requires immediate emergency care.
If you are getting ready to introduce fruit to your infant’s diet, go easy on the bananas. If your baby (or you) have trouble breathing and get lightheaded after eating a banana (or any food or medication), get help immediately.
Introduce  bananas slowly and you may save a life! Or at least a stomach ache.

Stomach Aches
Get a stomach ache after a banana? There are several potential reasons for this. Make sure your bananas are ripe. Unripe bananas are starchy, and your body has to work hard to digest that much starch.
Stomach aches after a ripe banana can indicate an allergy. It may also be from a gastrointestinal disorder or infection.
You may want to talk to your doctor if after-banana stomach aches are new.

Bananas Have Serious Drug Interactions
The FDA lists four classes of drugs that you don’t want to mix with bananas.
Beta-blockers and ACE inhibitors are often proscribed for heart patients. They cause a surge of potassium in the blood stream. Eating bananas can lead to hyperkalemia.
Oxazolidine antibacterials and bananas can dangerously increase your blood pressure.
Diuretics help you remove water, sodium and chloride from your body. They are often prescribed for heart of liver problems. Mixing these with bananas can cause hyperkalemia.

Constipation and Gas
Eating unripe bananas and all that starch can stop up your system. Conversely, a nice ripe banana can get things moving again!
If you eat enough bananas, unripe or ripe, you may have a sudden attack of gas. Your body needs fiber to work properly. It just doesn’t need too much fiber all at once or if you are not used to eating a lot of fiber.

Conclusion
Bananas can be a very nice snack. Just keep in mind the dangers of eating bananas or feeding bananas to infants.
Don’t depend on bananas to help you lose weight. Always talk to your doctor if you are taking one of the drugs on the interaction list. And whatever you do, don’t eat too many bananas! Your body will not thank you and you may end up with a stomach ache or even a trip to the ER.

Magnesium
Magnesium may be helpful in terms of weight loss because it has been shown to help regulate blood sugar levels as well as reduce water weight and bloating. More generally, magnesium is used by the body to conduct nerve impulses, contract muscles, and maintain a normal heart rhythm by helping to transport calcium and potassium.

Phosphorus
Low phosphorus levels have been linked with high BMI (body mass index). A recent study found that supplementing with phosphorus helped obese people lower their BMIsignificantly. In addition, participants lost pounds, reduced their waist circumference, and reported feeling less hungry. The effect may have something to do with the role phosphorus plays in digesting carbohydrates, so adding a banana to any meal can be a wise choice when you’re dieting.

Tryptophan
Tryptophan is the building block of serotonin, which is our body’s feel-good chemical. It is a natural antidepressant that also helps to regulate our appetites. Getting enough serotonin in the brain, therefore, not only keeps you feeling positive about your weight loss efforts, it makes it easier to avoid overeating.

Phytoalexin
While not directly tied to weight loss, phytoalexin is another substance found in bananas that can serve as a natural antibiotic. It may therefore protect against food borne illness. It is also an anti-inflammatory and antioxidant compound and can help to prevent premature aging, which can do wonders for overall comfort with your appearance. Phytoalexin has also been credited with reducing the risk of cardiovascular disease, often brought on by a poor diet.

Magical Banana Smoothie
This smoothie is designed to help you slim down faster and more easily. The ingredients together prime your body to burn fat, sustain energy throughout the day, and maintain an even mood. If you don’t particularly like one of the ingredients, feel free to adjust the recipe to your liking. Other fat burning foods that could be used include green or oolong tea, whey protein, Greek yogurt, and kefir.
Ingredients:
– 1 banana
– Half a glass of plain non-fat natural yogurt
The calcium and protein are thought to help rev up the body’s fat burning capacity without impacting lean muscle. In studies, people who included yogurt in their diet plans 3x per day lost an incredible 81% more fat around their middles than those who dieted without yogurt.

Lemon juice has long been used as a weight loss supplement, but the science doesn’t necessarily back up this claim. Still, lemon juice is full of vitamin C, which helps keep you looking young as well as reduces your risk of developing cancer. Plus, it’s tasty!
– 2 tablespoons flaxseed
Flaxseed is full of healthy fiber to keep you feeling full longer. It also contains lignans, which can lower cholesterol and support a strong metabolism.
– 1 tablespoon coconut oil
Though coconut oil is a fat, it contains mostly medium-chain fatty acids that are metabolized differently than other fats. Coconut oil passes straight to the liver from the digestive tract, where it is either used for energy or excreted, but not stored as fat. Coconut oil may also boost your metabolism so that you burn more calories at rest.

– 1 pinch of cinnamon powder
Eating cinnamon has been found to significantly lower fasting blood sugar, triglycerides, LDL cholesterol, and total cholesterol. It may also delay stomach emptying after a meal, keeping you full longer. Researchers have additionally determined that treating fat cells with cinnamaldehyde, the element in cinnamon that imparts its flavor, improves the rate of fat burning.
– Half a teaspoon of ginger powder
Ginger gives you energy to fuel a good workout, as pep much as the caffeine in your morning coffee would. It also reduces the production of the stress hormone cortisol, which is linked to excess belly fat. Ginger can also help reduce appetite by regulating blood sugar and serum cholesterol.
To make the smoothie, simply blend all ingredients in a blender until smooth. Drink one every morning on an empty stomach for the best results.

Warnings
If you have high blood pressure (hypertension), it may be best to remove cinnamon and ginger from your smoothie recipe. Pregnant women should restrict their ginger intake to 1 gram per day. Ask your doctor if this banana smoothie is right for you. The recipe can be adjusted to better meet your individual needs.
Whether you are deliberately trying to lose weight or just want to be healthier, this magical banana smoothie has what you need. Its ample nutrition and natural mood-elevating capacity makes it a fantastic choice for just about anyone.
If you’re a regular breakfast-skipper, the smoothie is light enough that you won’t feel bogged down. And if you usually rely on sugary cereals or starchy pancakes, you’ll find that this breakfast has a pleasingly sweet taste that actually provides sustained energy rather than a burst and a crash.
So enjoy your daily smoothie in conjunction with regular exercise and watch the pounds melt away. Good luck on your journey!

Будьте бдительны, выбирая бананы

Уверен, что каждый человек хоть раз в жизни отрывал с банана этикеточку. Такой маленький стикер. Теперь советую обращать на него внимание еще во время покупки этих фруктов, поскольку цифры на стикере имеют особое значение.

1. Стикер из 4х цифр, первая из которых "3" или"4". В данном случае комбинация расшифровывается просто: бананы были выращены по принципам интенсивного сельского хозяйства. Это значит, что для выращивание использовались пестициды и удобрения.

2. Стикер из 5 цифр, первая из которых "9". Это значит, что для выращивание бананов использовали органическое земледелие. Этот способ практиковался тысячелетиями, пока не изобрели удобрения.

3. Стикер из 5 цифр, первая из которых "8". Это значит, что бананы, лежащие на прилавке, являются генетически модифицированным организмом, кратко - ГМО.
