PepsiCo is to spend billions of dollars to develop drinks and snacks and reformulate existing ones with lower sugar, salt and fat, as consumers demand healthier options and regulatory pressure intensifies amid an obesity epidemic（流行病）.

    The maker of Mountain Dew and Gatorade has been one of the earlier movers in the industry to offer products with reduced levels of unhealthy ingredients—PepsiCo claims a packet of its chips now contains less salt than a slice of white bread. However, its new 10-year plan makes clear it believes it still has a long way to go.

Shifting eating habits, including a sharp drop in consumption of sparkling drinks, have forced radical change on the industry. But those shifts have yet to be reflected in record obesity levels, which stand at 36.5% overall in the US.

    Indra Nooyi, PepsiCo chairman, said the plan to make its products healthier was important for the company’s growth. But on the subject of obesity, she pointed out that consumers’ lifestyles have changed significantly, with many people being more sedentary（久坐不动的）not least because more time is spent in front of computers. She said PepsiCo’s contribution was to produce healthier snacks that still tasted good.

    “Society has to change its habits,” she added. “We can’t do much to alter sedentary lifestyles, but we can provide consumers with great-tasting products, low in salt, sugar and fat. In the past we had to have a taste trade-off. But we’re breaking that trade-off.”

    PepsiCo’s plan for its foods and drinks is based on guidelines from the World Health Organization, which last week backed using taxes on sparkling drinks to reduce sugar consumption. Initiatives also include efforts to reduce its environmental impact, water consumption and materials used in packaging by 2025.

    PepsiCo did not say exactly how much it planned to invest to reach its goals. However, Dr. Mehmood Khan, chief scientific officer, said the company had doubled research and development spending in the past five years and was “committed to sustaining investment”, adding that companies cannot cost-cut their way to increasing sales. PepsiCo’s research and development budget in 2015 was $754 million.

解析：D。根据题干中的PepsiCo 和in the future可定位至文章第二段。根据文章第二段最后一句可知，百事公司的十年计划中表明他们还有很长的路要走。再根据前一句可知，百事公司的产品减少了不健康的成分，由此可知，百事公司未来还会对自己的产品进行改进，因此选择D项。文章最后一段虽然提及invest（投资），但并未说明是否会投资资金研发新的零食，故排除。文章第三段提及obesity levels（肥胖水平），但文章是指美国的肥胖率为36.5%，并不是说百事公司要采取措施降低美国的肥胖率，故排除B项。文章第三段提及改变饮食习惯使得这一行业发生了根本的变化，此处并非指百事公司未来需要改变人们的饮食习惯，故排除C项。
