Eating whole, cooked peas and other beans may actually slow aging and make skin look younger.

2., it may be one of the best thing you can do for your health. People who eat these anti-aging foods, especially walnut (核桃), three times a week or more enjoy two to three more years of life.

Don’t panic — no one is saying you have to give up your steak — but doing a few meatless meals a week can increase the number of weeks in your life. 3. . Anti-aging foods like rice, beans, tofu, and buckwheat nearly as much protein per serving as meat does, and you get the added benefit of fiber, vitamins, and minerals.

Carrots are the typical healthy food. 4.. But did you know that carrots can not only lengthen your life span but also help you look younger?

Not only are blueberries delicious, but they’re also full of tons of nutrients, namely Vitamins A and C, as well as anti-aging antioxidants (抗氧化物质）like anthocyanin (花青素). A higher intake of anthocyanin may be associated with reductions in age-related decline to help preserve your health as you get older. The antioxidants found in blueberries can also protect against oxidative damage to your cells.5..

A. Since they are delicious

B. When it comes to anti-aging foods

C. If you eat nuts in your diet regularly

F. Adding plant sources of protein can help extend your life span

G. Therefore, it’s probably no surprise to hear they’re really good for you.

    According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS.

The study reports the newly-developed rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.

The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.

The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the “groundbreaking” discovery is “realistically the only way” that anti-HIV combination treatments can be produced at a cost low enough for the developing world.

They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.

The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.
