Shopping online for physicians online offers lots of benefits that you won't find shopping in a physicians online store or catalogue. For example, the Internet is always open - seven days a week, 24 hours a day.
Many physicians online bargains can only be found online. Shopping on the Internet is no less safe than shopping in a store or by mail. Keep the following tips in mind to help ensure that your physicians online shopping experience is a safe one.
Until recently, people used a technique called symmetric key cryptography to secure information being transmitted across public networks in order to make physicians online shopping more secure. This method involves encrypting and decrypting a physicians online message using the same key, which must be known to both parties in order to keep it private. The key is passed from one party to the other in a separate transmission, making it vulnerable to being stolen as it is passed along.
With public-key cryptography, separate keys are used to encrypt and decrypt a message, so that nothing but the encrypted message needs to be passed along. Each party in a physicians online transaction has a *key pair* which consists of two keys with a particular relationship that allows one to encrypt a message that the other can decrypt. One of these keys is made publicly available and the other is a private key. A physicians online order encrypted with a person's public key can't be decrypted with that same key, but can be decrypted with the private key that corresponds to it. If you sign a transaction with your bank using your private key, the bank can read it with your corresponding public key and know that only you could have sent it. This is the equivalent of a digital signature. While this takes the risk out of physicians online transactions if can be quite fiddly. Our recommended provider listed below makes it all much simpler.
Mad Carb Disease! Not All Carbohydrates in Foods Are Bad
by: Kim Beardsmore
Whether you're trying to lose weight or just want to eat healthier, you may be confused by the news you're hearing about carbohydrates. With so much attention focused on protein diets, there's been a consumer backlash against carbohydrates. As a result, many people misunderstand the role that carbohydrates play in a healthy diet.
Carbohydrates aren't all good or all bad. Some kinds promote health while others, when eaten often and in large quantities, may increase the risk for diabetes and coronary heart disease.
What are carbohydrates?
Carbohydrates come from a wide array of foods - bread, fruit, vegetables, rice, beans, milk, popcorn, potatoes, cookies, spaghetti, corn, and cherry pie. They also come in a variety of forms. The most common and abundant ones are sugars, fibers, and starches. The basic building blocks of all carbohydrates are sugar molecules.
The digestive system handles all carbohydrates in much the same way - it breaks them down (or tries to break them down) into single sugar molecules, since only these are small enough to absorb into the bloodstream. It also converts most digestible carbohydrates into glucose (also known as blood sugar), because cells are designed to use this as a universal energy source. This is why carbohydrates can make us feel energetic. Carbohydrates fuel our body. Your body stores glucose reserves in the muscles in the form of glycogen ready to be used when we exert ourselves.
Carbohydrates are the highest octane - the most desirable fuel source for your body's energy requirements. If you don't have an adequate source of carbohydrate your body may scavenge from dietary protein and fat to supply glucose. The problem is when you've depleted your stores of glycogen (stored glucose in muscle and lean tissue) your body turns to burning muscles or organs (lean muscle tissue) and dietary protein or fat to provide blood glucose to supply energy needs. When this happens, your basal metabolic rate drops because you have less lean muscle tissue burning calories and your body thinks its starving and cuts back on energy requirements.
So you should continue to eat carbohydrates discriminately selecting those which have the greatest health benefits.
The carbohydrates you consume should come from carbohydrate-rich foods that are close to the form that occurs in nature. The closer the carbohydrate food is as Mother Nature intended, the greater the density of other vital nutrients. If you are looking for health-enhancing sources of carbohydrates you should choose from:
Fruit: rich in fiber, vitamin A, vitamin C, folate, potassium and often vitamin E.
Vegetables: fiber, protein, vitamin A, vitamin C, often vitamin E, potassium and a wider variety of minerals than fruit.
Whole grains and grain foods: rich in fiber, protein, and some B vitamins and are very rich in minerals.
Legumes: an excellent source of protein, fiber folate, potassium, iron and several minerals.
Dairy foods: protein, vitamin D, calcium, phosphorus, potassium, riboflavin, and vitamin B12.
You can also source carbohydrates from processed foods such as soda pop or soft drinks, snacks such as cookies and chips, and alcohol. These generally are considered to be a poor food choice and should be consumed rarely. The carbohydrate source (sugar and flour) in these food choices has been highly refined processed. A diet rich in refined carbohydrates and processed foods has been associated with heart disease and onset of type 2 diabetes.
Why are these sources of carbohydrates to be avoided?
Whenever possible, replace highly processed grains, cereals, and sugars with minimally processed whole-grain products and ensure you have at least five serves of fruit and vegetables daily.
Rather than cut out carbs completely for a very short-term gain (usually weight loss), there are greater long-term health benefits in learning how to distinguish good carbs over bad carbs and incorporating healthy carbohydrates into your weight loss program.
