Stevia Extract

[Characteristics]

Stevia sugar features high sweetness and low calorie and its sweetness is 200 350  times of that  of cane sugar but its calorie is only 1/300 of that of cane sugar.

The component of stevia extract that gives it its sweetness is a mixture of various steviol glycosides. The components of sweetness in stevia leaves are stevioside, rebaudioside A, C, D, E and dulcoside A. Rebaudioside C, D, E and dulcoside A are small in quantity. The principal components are stevioside and rebaudioside A.

The quality of stevioside and rebaudiosideA is better than those of other components, which are commercially extracted and used in various applications.

The steviol glycosides present in stevia extract are referred to as “steviosides” or ¡°stevia extract¡±. Among these “steviosides”, the most common is Stevioside followed by RebaudiosideA. The Stevioside has a slight and pleasant herbal taste and the Rebaudioside-A has no herbal taste.

Although Rebaudioside C and dulcoside A are small in quantity in stevia extract, they are the major components giving bitter aftertaste.

[Function]

A large number of pharmaceutical tests have proved that stevia sugar has no side effects, carcinogens, and is safe for eating.

Compared with cane sugar, it can save 70% of the cost. With pure white color, pleasing taste and no peculiar smell, Stevia sugar is a new sugar source with broad perspective for development. Stevia rebaudianum sugar is the natural low hotsweet agent mostly similar to the flavor of cane sugar, approved to be used by State Ministry of Health and Ministry of Light Industry.

It is the third natural succedaneum of cane sugar and beet sugar with development and health care value, extracted from the leaves of the herbal vegetable of the composite family-stevia rebaudianum.

1. Fish.
Cold-water fish such as salmon, tuna, sardines and mackerel are rich in omega-3 fatty acids, which may help protect against dry eyes, macular degeneration and even cataracts.
If you don’t eat seafood, you can get a good supply of omega-3s by using fish oil supplements or taking vegetarian supplements that contain black currant seed oil or flaxseed oil.

2. Leafy Greens.
Spinach, kale and collard greens, to name a few, are full of lutein and zeaxanthin, plant pigments that can help stem the development of macular degeneration and cataracts. Broccoli, peas and avocados are also good sources of this powerful antioxidant duo.

3. Eggs.
The vitamins and nutrients in eggs, including lutein and vitamin A (which may protect against night blindness and dry eyes), promote eye health and function.

4. Whole Grains.
A diet containing foods with a low glycemic index (GI) can help reduce your risk for age-related macular degeneration. Swap refined carbohydrates for quinoa, brown rice, whole oats and whole-wheat breads and pasta. The vitamin E, zinc and niacin found in whole grains also help promote overall eye health.

5. Citrus Fruits and Berries.
Oranges, grapefruits, lemons and berries are high in vitamin C, which may reduce the risk of cataracts and macular degeneration.

6. Nuts.
Pistachios, walnuts, almonds — whichever type tickles your fancy — are rich in omega-3 fatty acids and vitamin E that boost your eye health.

7. Colorful Fruits and Vegetables.
Foods such as carrots, tomatoes, bell peppers, strawberries, pumpkin, corn and cantaloupe are excellent sources of vitamins A and C. And carotenoids — the compounds that give these fruits and vegetables their yellow, orange and red pigments — are thought to help decrease the risk of many eye diseases.

8. Legumes.
Kidney beans, black-eyed peas and lentils are good sources of bioflavonoids and zinc — and can help protect the retina and lower the risk for developing macular degeneration and cataracts.

9. Fish Oil, Flaxseed Oil and Black Currant Seed Oil.
These super supplements contain omega-3 fatty acids and have many eye health benefits, including helping to prevent or control dry eye syndrome as well as reduce the risk of macular degeneration and cataracts.

10. Sunflower Seeds.
Help keep your eyes healthy and disease-free by snacking on sunflowers seeds, which are excellent sources of vitamin E and zinc.

11. Beef.
In moderation, lean beef in your diet can boost your eye health. Beef contains zinc, which helps your body absorb vitamin A and may play a role in reducing risk of advanced age-related macular degeneration.
