Are sprouted seeds considered healthy?

Bean sprouts are baby bean plants.

Bean sprouts have been used for centuries for their nutritional and medical benefits. Chinese physicians prescribed sprouts over 5,000 years ago. Bean sprouts have continued to be a staple in Asian cuisine. Although accounts of sprouting appear in the Bible in the Book of Daniel, it took centuries for Europeans and Americans to fully appreciate bean sprouts. In the 1700?s, sailors suffered from scurvy (lack of vitamin C) during their voyages. In the 1770s, Captain James Cook had his sailors eat limes, lemons, and sprouts; all abundant sources of vitamin C. Along with other fresh fruits and vegetables, a continuous program of growing and eating sprouts was credited with preventing scurvy in sailors. During World War II, Dr. Clive McKay of Cornell University sparked American interest in sprouts. Dr. McKay had spent years researching sprouted soybeans. He wrote an article that touted soybean sprouts as "A vegetable that will grow in any climate, will rival meat in nutritive value, will mature in 3 to 5 days, may be planted any day of the year, will require neither soil nor sunshine, will rival tomatoes in Vitamin C, will be free of waste in preparation and can be cooked with little fuel

What are proteins from animal sources?

Any of your meats will contain protein. You can also find protein in egg whites, peanuts, peanut butter, jerky, and pork rinds.

Proteins are made up of chains of amino acids. All unrefined food has protein.

One-half cup of beans contains as much protein as an ounce of broiled steak. Plus, these nutritious nuggets are loaded with fiber to keep you feeling full for hours. Fifty grams of soy protein daily can help lower cholesterol about 3%. Eating soy protein instead of sources of protein higher in fat -- along with a healthy diet -- can be heart healthy.

The process by which fat became solid at room temperature is called?

Fats are made up of long chains of carbon with hydogen Adams attached to the sides. The more hydrogen there is the straighter the molecules are and the more molecules that will fit in a given area and therefore making the fat more dense and solid. This is where the term "Saturated Fat" comes from because the molecule is "Staturated" with hydrogen. Unsaturated fats have less hydrogen which makes the molecule bend and curl so that they don't fit close together and that makes the fat less dense and stay liquid at lower temperatures.

How do organisms use stored energy?

for growth, repairing cells, to move, for cellular work

What is visible fat and invisible fat?

Visible and Invisible fats depend on their food sources.

For instance, animal sources of fat are fatty meats, lard, butter, cheese, cream whole milk and egg yolk. Plant sources are vegetable oils, nuts, chocolate, avocados, olives and margarine

Visible fats are fats in foods that are purchased and used as fats, such as butter or margarine. Invisible fats or hidden fats are fats that are not immediately noticeable such as those in egg yolk, cheese, cream, and salad dressings. Invisible fats make it difficult for a regular diet for those who are on limited fat diets.

Visceral fat is fat which accumulates on your internal organs. It won't increase your waistline or you appearance, but it seems to correlate more strongly to a higher risk of disease than cutaneous fat. Subcutaneous fat is the kind we all know about residing directly under the skin.

Recent research has shown that dieting can help to reduce subcutaneous fat, but not visceral fat. Visceral fat appears to only be reduced through exercise. Eat right and exercise regularly.

What will happen if you eat expired eggs?

Why are drinking glasses made of glass?

A round glass is continuous about its cylindrical surface, so easy to form -- no seams required. A continuously curved surface is more resistant to impact breakage that one with flat facets. A cylindrical prism is greater in volume than any polygonal prism of the same width -- so the least amount of glass is needed for a vessel of any given capacity; this also means it will be of minimum height for its capacity. Minimum height means lower centre of gravity and thus greater stability (less likely to be knocked over). The glass is symmetrical about its vertical axis so you quickly grab it without having to think about its angular orientation about that axis. Its easier to hold safely and comfortably as it has no corners. It is easier and more convenient to drink from because a round rim curves upwards stopping the escape of liqiud from the corners of your mouth whle you are drinking. Can't think of any more just now.

What is the definition of Gelation in food?

Gelationisation is the combination of an ingredient combined with a flour source, also known as a Cereal. Different types of flours give you a different outcome towards what you are cooking.

Arrowroot -

Doesn't make your substance thick, it makes it very fine and thin.

It looks very musty and very translucent. Like icing on a cake.

Cornflower -

Makes your substance think but not very rich. It looks very milky and

pale. So, you wouldn't classify this as translucent. Also it just looks like a cloud.

Rice flour -

The greatest flour to make your substance very verythick. But also makes the food look grainy and looks abit like baby food. Or for a better image like mashed potato.

Plain flour -

Self-rasing or just Plain flour makes your substance a designated colour white. It will turn food lumpy and very grainy. So, not very thick but thick.

I've just boiled these flours with hot water over a stove.

So, the out may be different from actual foods.

So, pretty much, gelationisation is making food thicker and giving more detail and different texture.

Why does your soup get thin while eating it?

Without knowing what kind of soup or how you are eating it, I will relay this story:

While doing R&D in my early years, my supervisor commented that sometimes his new Instant Spaghetti Sauce would get watery upon sitting. It turns out that he would taste some and put his spoon back into the sauce. He used a pre-gellatinized starch and the enzymes carried from his mouth via the spoon to the sauce actually started the digestion process and broke down the hydrated starch which resulted in a watery sauce.

What are facts about fats oils and sweets?
