Why you should eat MORE avocado toast: Millennials’ eating habits ‘alter their appetites, making them less hungry’Mon 06 2017 | admin
- A study claims foods rich in polyunsaturated fats may alter hunger hormones
- These fatty acids include plant-based oils, salmon, avocado and nuts
- Experts found diets high in these fats reduced hunger and increased satiety
- These fats have also been linked to preserving memory and increasing lifespans
Millennials’ love for quinoa, hummus and avocado toast may be changing how their body reacts to hunger, a new study claims.
Foods rich in polyunsaturated fats have already been linked to preserving memory and improving problem-solving abilities as a person ages. Now research claims these fatty acids that are a staple in millennials’ diets may influence their hormones and change their appetite.
Scientists at the University of Georgia say this change can lead to overall weight loss and could be a tool in combating the obesity epidemic in America. Researchers examined study participants’ physiological hunger and satiety by measuring how their hormones changed based on a heavy polyunsaturated fat diet.
These healthy fats are found in high levels in salmon, nuts, seeds, olive oil and other plant-based oils.
The study found that individuals aged 18-35 who consumed high levels of polyunsaturated fats were less hungry and felt full for longer, compared to those who didn’t eat this way. Experts said this better appetite control was caused by a decrease in the hormone that controls hunger, ghrelin, and an increase in the hormone that controls satiety, peptide.
Study researcher Dr Jamie Cooper said: ‘Appetite hormones play an important role in regulating how much we eat. These findings tell us that eating foods rich in polyunsaturated fats, like those found in walnuts, may favorably change appetite hormones so that we can feel fuller for longer’.
The study notes that longer and larger studies need to be conducted to look at the long-term benefits of this diet.
If these healthy fats do influence how the body reacts to hunger, it could be used to help combat the high levels of obesity in the US and around the world.
Previous research from the University of Illinois found that these fats found in fish and nuts could help preserve memory. Omega-3 and 6 fatty acids in these food groups protect the areas of the brain that are most affected by aging, according to the study. They help to preserve the frontoparietal cortex – a brain network responsible for problem solving, the research adds.
These same fats may also aid maintenance of the fornix, which is a small brain region that has previously been linked to memory and Alzheimer’s disease, the study revealed. Alzheimer’s, the most common form of dementia, affects 5.4 million people in the US and 850,000 in the UK.
Another study by Stanford University School of Medicine found olive oil, a polyunsaturated fat, could help increase a person’s lifespan. The researchers believe the fat helps to protect cells from the signs of aging and allows the body to quickly access energy from foods.
Lead author Professor Anne Brunet said: ‘We have known for some time metabolic changes can affect lifespan, but we expected the long-lived animals in our study would be thinner.’
It may also explain why southern Europeans, who frequently eat olive oil in their Mediterranean diet, live longer and have lower rates of heart disease, despite consuming more fat.
