A large analysis of hundreds of studies set out to look at the health effects of many food groups and has confirmed that plant foods are more protective than animal foods against chronic diseases that are related to diet.
According to the study, fruit and vegetables are extremely protective, showing the ability to significantly reduce the risk of heart disease, cancer and obesity. The only negative effect – a higher risk of digestive cancers – possibly stems from increased consumption of pickled vegetables.
It also found that high consumption of wholegrains may significantly reduce the risks of type 2 diabetes, heart disease and cancer. The opposite also applied – a high consumption of refined cereals can increase the risk of diabetes and obesity.
The frequent consumption of pulses was also associated with a significantly reduced risk of cancer, while the only possible negative effect was an increased risk of stomach cancer from a high intake of fermented soya foods, possibly due to combining with other foods). The analysis also revealed that diets rich in pulses improve blood sugar control and significantly reduce heart disease risk.
The highest consumption of nuts and seeds was shown to lead to weight gain – understandable due to their high fat – but overall, they can help improve blood sugar control and significantly cut the risk of heart disease.
