Nestle is in damage control mode after a report showed the company was aware more than 60% of its food products were unhealthy.

The company will implement new nutrition and health plans to immediately fix this, it said.

The Swiss food and beverage company said it would be looking at all its food products to ensure they meet the nutritional needs of consumers. The company is drafting a new "companywide project" that will improve their nutrition.

An internal document said Nestle was aware that more than 60% of its mainstream products "did not meet the recognized definition of health." Financial Times reported Nestle acknowledged some of its food and beverage products would never be healthy - no matter how much they tweak them.

The internal document was circulated among the company's top executives earlier in the year. It said 37% only of the company's products - excluding nonhuman consumables such as pet food - achieved a rating of more than 3.5 points under Australia's Health Star Rating system.

Around 99% of the company's ice cream and confectionery scored fewer than 3.5 points. About 96% of its beverages scored fewer than 3.5 points. The report excluded products such as baby food and those produced by its health science division.

Nestle is trying to make its products "healthier." Over the past seven years, the company said it reduced the sugar and sodium content of its products by around 15%.

"We believe that a healthy diet means finding a balance between well-being and enjoyment. This includes having space for some indulgent foods, consumed in moderation. Our direction of travel has not changed and is clear: we will continue to make our portfolio tastier and healthier," Nestle said.
