Does fruit juice have less sugar than soda ?

Study shows there’s not much difference. In fact fruit juice may have more sugar than soda itself.

According to Time.com, “A new report from researchers at the University of Glasgow in the U.K. equated your glass of fruit juice to your can of soda—just with a few more vitamins.”

The study says that an 8-oz serving of soda contains about 26 to 31 grams (g) of sugar, while Welch’s Essentials Orange Pineapple Apple Juice Cocktail, although boasting that it has “no high fructose corn syrup” and that’s true, nevertheless contains added sugar for a total of 31 g per cup.

Thus, the question is: Is fruit juice a healthy swap?

Study by Maxine Siegel, R.D., shows that “While the vitamins, minerals, and antioxidants in fruit juice give it a nutritional edge over soda, it can have the same—or more—sugars and calories”. Maxine Seigel is the head if CR’s food-testing lab.

Seigel says that a cup of grape juice has 36 grams of sugar, a few grams higher, compared with 27 grams of sugars in a cup of grape soda.

Additionally Seigel says that “The sugars are natural, but your body processes them in the same way as the added sugars in soda,” He explains that compared with eating the fruit itself, “ the sugars in juice are digested and released into your bloodstream faster, causing blood glucose levels to spike.”

This causes the body to pump out large amounts of insulin, which can prompt fat storage and increase the risk of type 2 diabetes. If you eat the whole fruit, the process is entirely different. “In whole fruit, the sugars are encased inside the plant’s cells, so your body has to work harder to break them down.”

Siegel sustains that the fiber that fruit contains tends to slow the digestion and that combination, “will likely fill you up long before you eat enough fruit to consume the amount of sugars in a glass of juice.”

Think about this: If you’re cutting down on soda because the carbonation bothers you, the acidic juices from citrus fruits can also also bring irritation to your stomach.

Experts recommend that if you want to drop soda and drink juice instead, it is best to trade soda for water into which you add either some fruit slices or just a splash of fruit juice for flavor.

A more detailed study of how sugar enters our body cells describes the process as follows:

Facilitated diffusion, a form of passive transport, is the process that allows sugars to enter cells. Scientists also refer to this process as facilitated transport. During the process, glucose crosses the cell membrane.

Some things, are unable to pass through the lipid layer of the cell wall, due to the hydrophobic (the part of the cell that rejects or does not like water) nature of the lipids, although small molecules such as oxygen are able to pass easily.

Sugar molecules are able to pass through proteins that form what is called the transmembrane channels. These channels have gates that open and close, allowing selected molecules through the cell walls. That is how the cell protects itself from foreign objects that may be harmful to it, a wonder of nature.

“Carrier proteins transport the larger molecules, including glucose and amino acids. Closing these gates protects the cell from disease and potential danger.”

“The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells. The cell membranes of almost all living organisms and many viruses are made of a lipid bilayer, as are the membranes surrounding the cell nucleus and other sub-cellular structures. The lipid bilayer is the barrier that keeps ions, proteins and other molecules where they are needed and prevents them from diffusing into areas where they should not be. Lipid bilayers are ideally suited to this role, even though they are only a few nanometers in width,[1] they are impermeable to most water-soluble (hydrophilic) molecules.” Courtesy of Wikipedia.org

According to biologists, all the processes the cell carries out require energy, like anything else in the physical world. Generating energy is a basic process of all of our body cells. This process is ubiquitous in every organic cell of living matter.

It is generated by rearranging glucose molecules by controlled oxidation or cellular respiration. All plants, bacteria and algae create the carbohydrates needed for cellular respiration through the well known process of photosynthesis that we are all familiar with. Then they transport all the carbohydrates to the cells and finally produce chemical burning or oxidize them for energy.

Animals, “as well as some bacteria and certain protists (A protist is any eukaryotic* organism that has cells with nuclei and is not an animal, plant or fungus), are unable to produce carbohydrates and depend on their environment for this energy supply. Once the cell releases the energy from glucose, it stores it in the bonds of ATP.” (Adenosine triphosphate abbreviated as ATP is a coenzyme that cells use for energy storage.)

Why do we Need for a Lipid Bilayer in our human cells ?

“The interior of the cell is primarily made of water. However, the exterior of the cell is usually surrounded by watery fluid.” This means that the plasma membrane does not consist of just one layer of phospholipids.

The real reason is that the hydrophobic (or water fearing) tail region would have to interact with one of the watery regions inside or outside of the cell. The cells have been marvelously designed with hard coded information in their DNA in order to have two layers of phospholipids.

Hard coded information in the cell is similar to your computer’s hard drive- someone programed it to store data-  disseminate it when necessary, and ultimately do its job , which is to process the installed software.

The cell’s hard coded DNA, in this case, replicates itself and does it with such precision so that it hardly has any replication errors, and creates liver, heart, brain, skin, etc. cells as it has been programmed to do. It also knows when to stop reproducing. Otherwise, your liver or your heart or your brain would grow to enormous proportions. It has all been perfectly designed ahead of time.

The bilayer creates a ‘sandwich’ type of arrangement. The hydrophilic, or water loving, heads of each layer face the watery environment inside and outside of the cell.

The hydrophobic, or water repellent, tails are built to be confined to the middle. This creates (water repellent situation) a hydrophobic region between the two layers of heads.

It is obvious that this, marvelous mechanical, biological box allows the plasma membrane to be stable in this dual watery environment. All evident of well thought out and excellent design.
