POZITIVNI I NEGATIVNI EFEKTI KOFEINA

Mehanizam delovanja Kofeina, da li pozitivno ili negativno utiče na organizam, kakvo je njegovo delovanje na fizičku aktivnost, i još par zanimljivih pitanja, obradićemo u narednom tekstu.

 

Kofein je prirodni alkaloid, koji se dobija iz zrna kafe, iz listova čaja i iz kakaovih zrna. Dodaje se veštačkim pićima ( koka kola ). On je prirodni psihostimulans i utiče na centralni nervni sistem.

Pozitivne strane Kofeina

% nutritijenata u šoljici kafe: Vitamin B12 11%, Vitamin B5 6%, Vitamin B1 2%, Vitamin B3 2%, Magnezijum 3%, Fosfor 1%. Kafa sadrži male količine vitamina ali je snažan antioksidans.

Nije potpuno jasno zašto kofein poseduje očigledne ergogene efekte, i ako postoji hipoteza da on stimuliše simpatički nervni sistem i povećava utrošak masnih kiselina, čime se štede ograničene zalihe glikogena u mišićima i jetri. Kao stimulans centralnog nervnog sistema, kofein može da smanji osećaj zamora, što omogućava produženo trajanje aktivnosti i unapređenje sportskih rezultata. Konačno, kofein igra značajnu ulogu u oslobađanju jona kalcijuma iz sarkoplazmatskog retikuluma u mišićnoj ćeliji. Ovo dalje može dovesti do stimulisanja snažnije mišićne kontrakcije naročito tokom anaerobnih sportova i sportova snage. Međutim, novije studije ukazuju da ukoliko povećamo unos slobodnih masnih kiselina i istovremeno unosimo kofein, neće doći do povećanja njihove oksidacije, niti uštede glikogena. Kompetitivna prednost se, izgleda, pre svega odnosi na ulogu kofeina u stimulaciji centralnog nervnog sistema. Tokom sportova izdržljivosti, kofein dokazano smanjuje osećaj zamora, povećava koncentraciju i pažnju, dok tokom treninga snage, ili kratkim eksplozivnim aktivnostima, kofein ima ulogu pokretača kontrakcije skeletnih mišića.

Negativne strane Kofeina

Korisnici mogu postati zavisni od kofenia, usled previše konzumiranja. Dok je niska i umerena doza, generalno bezbedna. Oni koji naglo prestanu da konzumiraju kofein, a ranije su bili zavisnici, imaju problem sa glavoboljom i mentalnim zamorom. To stanje traje nekoliko dana dok se telo ne prilagodi.

Previše unošenje kofeina izaziva, povećanu nervozu i poremećaj sna. To ima za posledicu da, usled unošenja kofeina kako bi smanjili dnevni umor, dolazi do nesanice. Unošeneje kofeina negativno utiče u interakciji sa nekim lekovima. Kofein povećava nivo šećera u krvi, što pravi problem osobama koji imaju Dijabetes tipa 2 i kontrolisanje insulina. Osobe koje imaju povišen pritisak i dijabetes trebaju da izbegavaju kofein. Studije kažu i da žene koje piju više od 3 šoljice kafe ( 300 mg kofeina ) dnevno, dovodi do gubitka koštane mase u kičmenom stubu, za vreme postmenopauze. Dolazi do nedostatka Kalcijuma u kostima. Kofein može takođe da dovede do stomačnih problema, usled gorušice i stomačne kiseline.

ZDRAVLJE I ISHRANA DANAS

Ovih dana se puno priča o tome da li unos mesa povećava rizik za dobijanje kancera, da li je hrana puna aditiva, šta se sve dodaje u ishranu, da li zdravo živimo i kako se hranimo… Evo nekih korisnih informacija, koje se iznose na osnovu istraživanja u poslednje vreme, od strane stručnjaka, doktora i nutricionista.

 

U Srbiji se prosečno dnevno pojede 500g belog hleba po stanovniku

Beli hleb nije štetan kao sto se priča, samo zavisi koliku količinu pojedete

Za žitarice je poželjno da proklijaju kada se unose kroz ishranu, kako bi sadržale maksimalan procenat biljnih vlakana

Gluten je štetan samo za ljude koji imaju celijakiju ( alergiju )

Kod žitarica je najbitnije da budu adekvatno obrađene i oprane

Potapanje žitarica u vodi je obavezno zbog fitinske kiseline

Najbitniji je kvalitet kalorija koji se unosi tokom dana

Dijeta u broju kalorija koje preporučuje, mora da sadži sve hranjive kalorije, a ne da bude eliminaciona dijeta

Ishrana treba da bude raznovrsna, nikako jedna namernica ne može da zameni drugu

Hrana nije lek i ne treba da se definiše tako, ne sme da nosi nikakvu oznaku kao lek

Manje od 8% tokom dana, treba da bude unos zasićenih masti životinjskog porekla

Smanjiti unos crvenog mesa sa 90g na 70g dnevno, razlog je smanjivanje rizika od dobijanja karcinoma

Ako na ovo smanjenje unosa crvenog mesa, jedete još više voća I povrća, smanjiće te još više rizik od dobijanja karcinoma

Mesne prerađevine često sadrže Azbest koji je jako štetan za organizam

Ako totalno isključite meso iz ishrane, nećete imati dovoljnu količinu vitamina B12, koji je jako bitan za organizam

Zbog loše hrane I ishrane dolazi do hormonalnih poremećaja u detinjstvu, rani pubertet

Zbog sve slabijeg kretanja nemamo dovoljno vitamina D3, koji se stvara pod dejstvom sunčevih zraka

Post u ishrani je koristan, jer stvara nove matične stanice

Kvalitet hrane kojom hranimo životinje, čije meso jedemo, uticaće I na naš organizam kasnije

Kažu stručnjaci: bolje jesti i “špricanu” jabuku, nego je ne jesti uopšte

 

MUSCLE FOOD

And if I’m not an advocate of large muscle mass and excessive muscle today we moved the best way through the food that needs to be applied to increase muscle mass. Increased muscle mass in both recreational, athletes or beginners have a very positive thing. First of all the body and muscle burns calories faster, which speeds up the metabolism of the whole body (the faster you will melt body fat and weight), the other aesthetic looks very nice, and the third might be the most important helps your body in proper posture and gives it vitality and strength. It is not easy to build big muscles so who say i will overbuild my muscle it is wrong. Some facts and suggestions in the text might sound beyond the usual advice, but will be explained why you should applied. This will be useful to anyone who needs to put on quality weight.

So lets start…

IMG_20151008_233833

The first part means that you need to eat a lot, but the right kind of food, distributed over more meals a day, total you should enter two grams of protein per kilogram of body weight. You will need a lot of carbohydrates to encourage the desire to exercise and ability to recover after a hard workout at the gym. Then you should plan your diet so devise that it contains the very best food for building muscle mass. Now I will introduce to you foods that your nutritional program should include as much as possible.

BEEF. Many mistaken discarded fat from food, thinking that it will increase the level of fat in the body. But with Omega-3 fatty acids in fish, saturated fat in beef actually stimulate growth. Too little saturated fat in the diet does not promote the growth of testosterone and insuluna. Beef is also a source of cholesterol, the main ingredient that helps the body to produce its own testosterone. Beef is also classified as good sources of creatine, B vitamins and zinc. The best options are low fat beef parts

EGGS. There are different ways in which nutritionists treat food on its ability to stimulate growth. Eggs are at the top of almost every list since it is extremely easy absorb- body can very quickly to explain this food into amino acids. Eggs are also rich in healthy fats, saturated fats and lecithin, they help the body to develop muscle mass.Try to avoid the yolk but do not totally excluded from the diet.

SALMON. 100 grams of salmon contains 20 grams of protein, which is equally important, 2.5 g of omega-3 fatty acids, those healthy fats that reduce inflammation of the muscle to stimulate its reconstruction and help in controlling cortisol (as cortisol decreases, the level of testosterone per rule growing, stimulate muscle growth). A diet rich in omega-3 fatty acids also helps that most of the glucose you eat is transported to the muscles rather than deposited as fat.

APPLE JUICE. Extreme exercise in the gym break down muscle. However, the beneficial effects are manifested only later, when the body regenerates and becomes larger than before. Apple juice drunk before training the body supplied with carbohydrates and quickly gives him the necessary energy (for glucose), which is also of long duration (due to fructose). This hampers the creation of cortisol thus decreasing the harmful effects on the muscle fibers.

BUTTERMILK. If you are trying to put on weight, do not drink skim milk or one with low fat. These types are for those on a diet. Around half a liter of whole milk contains 16 grams of protein and 16 g fat. The fat in milk is usually composed of short chains than is the case with fats that are found in other foods. Such fats are slightly anabolic, helping to prevent muscle breakdown, and they are rarely deposited as fat in the body. The fat in milk also help the body absorb vitamin D, which has recently been discovered that reduces the risk of cancers.

WHITE BREAD. You probably know that you should avoid refined carbohydrates because they have less fiber and healthy nutrients, and also raise insulin levels. But white bread is one of the perfect choice of food immediately after completion of the training. Then you need carbohydrates that are rapidly digested to reimbursement level of glycogen in the muscles and stimulated insulin levels in order to achieve muscle growth and to reduce the production of cortisol after training. Two pieces of bread retain 25g carbs are digested very quickly after training.

PASTA. Building muscle requires a lot of carbohydrates as fuel. What is more important is that carbohydrates radically alter protein metabolism by increasing the efficiency with which ingested protein gets into the muscle and stimulate growth. Without carbohydrates you consume protein that does not perform quite as efficiently its job when it comes to stimulating growth. One cup of cooked pasta in the form contains about 45 grams of carbohydrate.

GARLIC. Garlic can dramatically alter the hormones in your body. Growth is associated with the consumption of real macronutrients (carbohydrates, protein and fat) at the right time of day. But it is also associated with adequate hormonal environment that stimulates growth. Animal studies have shown that garlic in combination with large amounts of protein increases testosterone levels and prevents the degradation of muscle. At the micro level, it is the very definition of the ideal anabolic situation.

YOGURT. Natural yogurt, obtained either from whole milk was than with low fat, falls into a healthy diet. It is best to opt for yogurt that contains active cultures of “good bacteria”. But on the label, do not search on the word bacteria. Instead, look for Lactobacillius acidophilus, L. casei, L. reuteri and Bifidobacterium bifidum. These probiotic bacteria pass through the stomach to red tract where help the body maintain a healthy balance of bacteria that live there. These good bacteria strengthen the immune system which helps in the process of recovery and reduces the formation of agents responsible for inflammation, while increasing the absorption of nutrients. Another very useful ingredient in yogurt is calcium, which controls muscle contraction and can significantly reduce the deposition of fat.

OLIVE OIL. This oil control inflammation in the body, generally associated with better recovery. Olive oil also supports testosterone and, like any other source of fat, calories are what help the body to remain in an anabolic state. Olive oil is also rich and healthy fats.

 

This text was written on the basis of many years of research and experience, the parts that are scientifically proven and parts taken from many years of experience and top sportsmen and fans of muscles and muscle mass. I think the allegation is substantiated by sufficient evidence and knowledge so that you can start using. And most importantly, everything is natural and without anabolic steroids.
