Some vitamins, minerals,
and diet types can help enhance hair, skin, and nail health. These include
omega-3 fatty acids, vitamins A, C, and E, and high-protein, low-glycemic
diets.
Hair
Research shows that
women who ate low-glycemic diets rich in complex carbohydrates, vitamins A, B
and C, and minerals like zinc and magnesium might have less hair loss during
menopause.
A 2019 review indicated
micronutrient deficiencies such as diets lacking biotin, vitamins A and C, and
zinc could affect hair health.
In addition, protein is
an essential part of a hair-healthy diet.
“Our hair is made of a
protein called keratin, so a diet insufficient in protein may make hair
brittle,” Paula Doebrich, MPH, RDN of Happea Nutrition says.
People with vitamin A
deficiency may note detrimental effects on their hair and skin.
Skin
People with
micronutrient deficiencies, such as biotin, vitamins A and C, and zinc, are
more likely to have less healthy skin and nails. Eating a plant-based diet
could benefit skin barrier health and function.
Nails
Nails are keratin-rich,
and nutrition may impact their health. Any nutritional deficiency, such as
calcium or iron, could affect nail growth.
Thus we should eat foods
like salmon, nuts, avocados, and fruits and vegetables.
Fatty fish
“Omega-3 fatty
acids could help reduce inflammation and redness in the body and skin,” says
Katie Tomaschko, a private practitioner in Buffalo, N.Y.
“They’re also a rich
source of protein, the powerful antioxidant vitamin E, and biotin, a nutrient
that supports keratin production and can benefit the hair and skin.”
Fish she recommends are salmon, herring and mackerel.
Sweet potatoes
Sweet potatoes are rich
in the carotenoid beta-carotene, which is a precursor for vitamin A.
“Vitamin A promotes
keratin production and is essential for skin and nail health,” Tomaschko
says.
Anthocyanins in purple
sweet potatoes have anti-oxidant properties that may improve skin inflammation.
Antioxidants can also help protect against free radicals, which can trigger
premature aging.
Nuts and seeds
Nuts, such as almonds
and walnuts, also boast the antioxidant vitamin E, which helps combat oxidative
damage and has anti-inflammatory properties that may help absorb energy from UV
light and protect against skin damage and visible aging signs, like fine lines
and sun spots.
Some seeds, particularly
sunflower seeds, are good sources of biotin, protein and vitamin E.
Fruits and vegetables
Eating fruits and
vegetables was linked to skin health and vitamin C could help with
collagen production and reduce the appearance of wrinkles.
Dark, leafy greens
Loading up on leafy
greens provides the body with plenty of nutrients that can benefit the hair,
skin, and nails. Examples of dark, leafy greens include spinach, kale, swiss
chard, bok choy and collard greens.
Avocados
Avocados are rich in
healthy fats and nutrients that promote skin and nail health, including
vitamins C, A and E.
One cup of mashed or
pureed avocado contains 23 milligrams of vitamin C, 16.1 micrograms of vitamin
A and about 5 milligrams of vitamin E.
Oysters
“Oysters are an
excellent source of zinc,” Doebrich says. “Zinc is needed for hair growth and
tissue repair.”
One cup of oysters
contains 97.5 milligrams of zinc and also loaded with protein — 14.2 grams per
cup.
On the other hand, some
foods are better enjoyed occasionally, including ultra-processed and fried
foods, sugary treats and beverages, and alcohol. These foods have been
linked to issues like hair loss, skin aging, skin dehydration and atopic
dermatitis.
Alcohol
“Alcohol
dehydrates you and preoccupies our bodies with filtering it out, thus
preventing our bodies from doing their normal day-to-day maintenance, which
includes working to sustain our skin and nail health,” Tomaschko says.
Heavy drinking, defined
as more than eight beverages per week, was associated with facial aging signs.
These included:
- · under-eye puffiness
- · midface volume loss
- · increased blood vessel visibility
- · upper facial lines
Processed foods
Steering clear of
ultra-processed foods may decrease your risk of skin issues.
“These foods can run the
risk of causing inflammation in the body, which would be harmful for our skin
and nail health,” Tomaschko says.
A 2021 study of more
than 15,000 Chinese adults indicated that processed food intake may increase
risk of atopic dermatitis while some studies linked food processing methods
like frying and high-fat diets to skin aging.
Ultra-sweetened foods
and drinks
Sugary diets can
increase skin aging.
Thus it is best to avoid
ultra-processed, sweetened foods. You do not have to nix them all together, but
limiting intake can decrease inflammation and skin dehydration, bettering hair,
skin and nail health.
