Dietitian Maria Mukhina warned that eating only vegetables could lead to protein deficiency. NHS and Harvard public health guidance says a well-planned plant-based diet can be nutritionally adequate.
Dietitian Maria Mukhina warned that a diet made up only of vegetables could lead to protein deficiency. She also linked such a diet to changes in the body's acid-base balance and possible health problems.
Claims that vegetables activate viruses or alter blood pH in healthy people are not supported by the cited medical evidence. The Harvard T.H. Chan School of Public Health says controlled studies have not shown that diet significantly changes blood acidity.
A fully plant-based diet can be balanced, but it needs variety and planning. The NHS recommends protein sources such as beans, tofu, nuts and seeds, along with foods fortified with essential vitamins and minerals.
