Annex 3 provides a very limited table of the nutrient content of foods that are known to be quite widely used in developing countries. Sago has low protein content. In the past few years, we've discovered that chemo frequently causes secondary cancers, can actually FEED tumors, and that chemo traumatizes the brain for years. And the results were amazing.

And, one day, perhaps, even off the planet, as NASA has chosen it for space missions. One of the healthiest and cheapest. If you look at a graph of affordability versus nutrition, you can see that the healthiest foods, like dark green leafy vegetables, may also be among the cheapest. And the highest nutrient-rich food scores per dollar were obtained for sweet potatoes. In , a unique protein was discovered in sweet potatoes. It was originally tested against leukemia cells, and appears to suppress the growth of leukemia cells in a petri dish.
But, how would a sweet potato protein ever get into our bloodstream? As soon as most proteins hit our stomach, they start getting digested. So, they tried sweet potato protein against tongue cancer. Sweet potato constituents certainly come in contact with our mouth.
Tongue cancer is often treated with chemo. So, most recently it was tried on colorectal cancer cells, one of our most common and deadly cancers. Normally, we just surgically remove the colon. But, that only works in the early stages, since there are often micrometastases outside the colon that can subsequently lead to cancer recurrence and death.

Sweet potatoes are one of my favorite snacks. During the harsh Boston winters, I used to put two freshly microwaved sweet potatoes in my coat pockets as natural hand-warmers. And then when they cooled down, my hand warmers became instant healthy snacks!

Depending on the amount of water that is extracted from the tofu curds, fresh tofu can be divided into four main varieties: Fresh tofu is usually sold completely immersed in water to maintain its moisture content and freshness, and to retard bacterial growth.
Soy milk is mixed with seawater , or saline water made with sea salt , so that it curdles. Freshly made sun-dubu is eaten boiled with little or no seasoning. Manufactured sundubu is usually sold in tubes. It's normally coagulated at the restaurant into a serving container.
Many home cooks coagulate it with agar. It is undrained, unpressed tofu that contains a high moisture content. This is a type of soft tofu with an very high moisture content. Because it is difficult to pick up with chopsticks , it is generally eaten with a spoon. With the addition of flavorings such as finely chopped spring onions , dried shrimp , soy sauce or chilli sauce , douhua is a popular breakfast dish across China.
In Malaysia, douhua is usually served warm with white or dark palm sugar syrup, or served cold with longans. Some variation exists among soft tofus. The texture of black bean tofu is slightly more gelatinous than regular douhua and the color is greyish in tone. This type of tofu is eaten for its earthy "black bean taste".
Although drained and pressed, this form of fresh tofu retains a high moisture content. It has the firmness of raw meat and bounces back readily when pressed. The texture of the inside of the tofu is similar to that of a firm custard.
The skin of this form of tofu retains the pattern of the muslin used to drain it and the outside is slightly more resistant to damage than the inside. It can be picked up easily with chopsticks. These types of firm tofu are produced with seawater instead of nigari magnesium chloride , or using concentrated soy milk.
Some of them are squeezed using heavy weights to eliminate excess moisture. These products are produced in areas where travelling is inconvenient, such as remote islands, mountain villages, and heavy snowfall areas. When sliced thinly this tofu can be crumbled easily. The skin of this form of tofu has the pattern of the muslin used to drain and press it.
Western firm tofu is milled and reformed after pressing. Su ji is a more common type of unflavored, extra-firm tofu. It cannot be crumbled and has a more rubbery texture.
Many forms of processed tofu exist. Some processing techniques probably [ citation needed ] originate before the days of refrigeration from the need to preserve tofu, or to increase its shelf life. Other production techniques are employed to create tofus with different textures and flavors. During freezing, the ice crystals puncture cell walls and facilitate the release of free and bound water and cause a decrease in total water content in tofu after freezing then thawing.
The initial protein-water bonds are irreversibly replaced by protein-protein bonds, which are more elastic which cause a structural change to the gel network and lead to an increase in textural properties such as hardness, springiness, cohesiveness and gumminess.
Two kinds of freeze-dried tofu are produced in Japan. They are usually rehydrated by being soaked in water prior to consumption. In their dehydrated state they do not require refrigeration. Tofu skin is produced when soy milk is boiled in an open, shallow pan, thus producing a film or skin composed primarily of a soy protein-lipid complex on the liquid surface. Its approximate composition is: Since tofu skin has a soft yet rubbery texture, it can be folded or shaped into different forms and cooked further to imitate meat in vegan cuisine.
Some factories dedicate their production to tofu skin and other soy membrane products. Tofu skin is commonly sold in the form of dried leaves or sheets. It is also an ingredient for vegetarian burgers in many Western nations. Due to their Asian origins and their textures, many food items are called "tofu", even though their production processes are not technically similar. For instance, many sweet almond tofus are actually gelatinous desserts hardened using agar or gelatin.
Some foods, such as Burmese tofu, are not coagulated from the "milk" of the legume but rather set in a manner similar to soft polenta , Korean muk , or the jidou liangfen of Yunnan province of southwest China. A similar dessert made with coconut milk or mango juices may occasionally be referred to as "coconut tofu" or "mango tofu", although such names are also given to hot dishes that use soy tofu and coconut or mango in the recipe.
