I am one of the people that firmly believes you should not drink your calories. It is for a variety of reasons, but primarily because it has negative effects on your blood glucose, and because your body does not absorb nutrients as well from a liquid as it does from solid foods, especially those with fiber.

Regarding juice, you are always better off eating the solid fruit or vegetable. Juice can be especially high in sugar (it may be natural fructose, but is often concentrated)... this causes spikes in blood glucose and then dramatic lows after your body produces the insulin it needs to counter it, causing loss of energy and increased hunger several hours later. Further more, if your body detects it has produced a higher than normal amount of insulin, it starts to produce cortisol (adrenaline) which can lead to symptoms of anxiety. Obviously some bodies are more efficient than others, so not everyone experiences these reactions enough that they would notice it... but many do. And even if you don't experience symptoms, your body will function more efficiently if stick to solid fruit.

Regarding soy and soy protein - there are claims that soy protein is bad for you, but typically those claims are referring to chemically modified soy products that you might find in highly processed foods. If you do a google search on "soy nutrition" you can read further about which soy products are healthful and which should be avoided. The bottom line is that soy is very good for you - and has even met FDA approval to make claims that it can lower risk of cancer and heart disease. Studies have also shown that high quantities of soy can improve kidney function, balance hormones, and a provide variety of other health benefits, though most people don't consume enough to experience these benefits. The recommended amount of soy is 25 grams of soy protein per day.

Soy milk is okay, but if you want to eat your soy instead of drinking it, try having some soy yogurt (really not bad at all), or roasted soy nuts (which come in some interesting varieties). I really like eating soy nuts because they are easy to carry around as a snack, and they are high in protein and fiber. 1 oz of soy nuts has 12-15 grams of protein.

Hope this info is helpful to you.
