A TOP nutritionist has told how a vegan diet can cause hair loss.
Nutritional therapist Cassandra Barns said that a diet without meat and fish affects the ability of hair cells to renew themselves.
She said: “Protein is one of the most important nutrients for healthy hair.
“Keratin, a substance that provides the strength and structure of hair, is a protein, and our body makes it from the proteins that we eat.”
Ms Barns is not the only nutritionist to have seen the devastating effect of veganism on people’s health.
Other health experts say more vegans are now returning to meat to regain energy and weight.
Dietitian Maria Bella, the founder of Top Balance Nutrition clinic in New York said that she quit veganism after two years because meat substitutes made her unhealthy.
She said an increasing number of vegan clients had complained of negative side effects such as fatigue and bloating.
Her company received 2,500 complaints from people who had bad reactions to meat substitutes which included nausea, violent vomiting, diarrhoea, and even life-threatening anaphylactic responses where people can’t breath properly.
Experts have also warned that not all vegan products on the market can provide healthy nutrition.
Jenna Farmer, a UK nutrition blogger, experienced unwanted symptoms herself.
She became vegan after being diagnosed with Crohn’s Disease believing it would help.
But she was quick to realise that the sudden diet change wasn’t working out.
She said: “The sudden increase in fibre was not kind to my gut… let’s leave it at that.
“I found energy levels difficult too – I wasn’t eating a huge range of food and giving up meat meant I was already increasing my risk of anaemia, which having IBD meant I was very prone to anyway.
“It was hard: I was tired, underweight and hungry.”
Cassandra Barns added: “If you want to remove animal protein from your diet, ensure you consume enough plant-based protein.
“This could include replacing fish and eggs, with beans, lentils, nuts and seeds.”
