Here are plenty of tips on how to strengthen your health through small but effective changes in your daily life.
Try Japanese sweet potatoes

Japanese sweet potatoes, with their white flesh and purple skin, are a seasonal favorite in Japan.
They are packed with fiber and antioxidants that benefit both gut and heart health.
Despite their natural sweetness, their complex carbs and fiber help regulate blood sugar.

A healthy alternative to sugar cravings

Japanese sweet potatoes make a naturally sweet yet blood sugar–friendly snack. They can replace sugary treats while keeping energy levels stable.
Add lemon zest to your meals

Lemon peel contains more antioxidants and vitamin C than the pulp itself. It can help fight harmful bacteria and fungi.
Grate a little zest over your meals, infuse it in water, or blend preserved lemons into dressings.
Boost immunity with lemon

Rich in vitamin C, lemon peel can also help defend the body against infections. Adding small amounts to your meals daily may support immune function.

Protect your cells with vitamin D

A recent study found that people who took 2,000 IU of vitamin D3 daily had longer telomeres and less DNA damage compared to those on a placebo.
Telomeres act as protective caps on DNA, and vitamin D may play a role in slowing their shortening, although research is ongoing.
Vitamin D and aging

Although the science is not yet conclusive, evidence suggests that vitamin D may help slow aspects of cellular aging, offering potential long-term benefits for health.
Avoid a melatonin hangover

Taking too much melatonin can cause grogginess the next morning.

Experts recommend no more than 1 milligram per day and choosing supplements verified by third-party testing.
Melatonin as a short-term aid

Melatonin is best used for short-term sleep disruptions, such as adjusting to a new schedule. Long-term use may interfere with the body’s natural hormone balance.
Balance your iron intake

Iron deficiency is common, especially among young women, but too much iron can be harmful.
Focus on food sources such as meals cooked in cast iron pans or iron-rich foods combined with vitamin C for better absorption.

Food over supplements

Nutrients are often more effective when consumed through whole foods rather than pills. Japanese sweet potatoes and lemon peel are prime examples of this principle.
Moderation is key

Whether it’s vitamin D, melatonin, or iron, balance matters. Too little or too much can be harmful, so moderate intake is essential for good health.
