Research published in Nutrients highlights the critical role of beta-carotene in preventing Vitamin A deficiency-related vision impairments https://www.mdpi.com/journal/nutrients

Global Sources of Vitamin A:
In Nigeria and West Africa, red palm oil, sweet potatoes, and carrots are abundant sources of Vitamin A. In the United States and Europe, common sources include dairy products, eggs, and fortified cereals. Globally, leafy greens such as spinach and kale provide beta-carotene, which the body converts into Vitamin A.

#3  Vitamin C: The Antioxidant Defender

Why It’s Important:
 Vitamin C is an antioxidant that helps prevent cataracts and slows macular degeneration, is abundant in oranges, pawpaw, and guava in Nigeria, and strawberries and bell peppers in the United States. Tomatoes, available worldwide, are also a great source.  A study in the Ophthalmology Times emphasized the role of antioxidants, including Vitamin C, in reducing cataract risks.https://www.ophthalmologytimes.com

Nigeria and West Africa: Oranges, pawpaw (papaya), and guava. United States and Europe: Oranges, strawberries, and bell peppers. Universal Superfood: Tomatoes, which are rich in Vitamin C and available globally.

#4 Lutein and Zeaxanthin: The Natural Sunglasses

Why They’re Important:
 Lutein and Zeaxanthin, often referred to as natural sunglasses, protect the retina and lens by filtering harmful blue light. Foods such as fluted pumpkin leaves in Nigeria, kale in Europe, and eggs globally are rich in these nutrients.  Research from JAMA Ophthalmology (2020) confirms that lutein and zeaxanthin reduce AMD risks.https://jamanetwork.com/journals/jamaophthalmology).

Global Sources of Lutein and Zeaxanthin:

Nigeria and West Africa: Fluted pumpkin leaves (ugu), amaranth, and yellow maize. United States and Europe: Kale, spinach, and zucchini. Universal Superfood: Eggs, a widely accessible and rich source of both nutrients.

#5  Zinc: The Night Vision Helper

Why It’s Important: Zinc is vital for producing melanin, is found in locust beans and cashews in West Africa, oysters in the United States, and pumpkin seeds globally. The Archives of Ophthalmology in its 2015 study underscores Zinc’s role in slowing AMD progression (https://jamanetwork.com).

Global Sources of Zinc: 

Nigeria and West Africa: Locust beans (iru), beans, and cashew nuts. United States and Europe: Shellfish (like oysters), red meat, and fortified cereals. Universal Superfood: Pumpkin seeds, which are rich in zinc and widely available.

#6   Vitamin E: The Cell Protector

Why It’s Important: Vitamin E is a potent antioxidant, protects eye cells from damage, and is found in peanuts and palm oil in Nigeria, almonds in the United States, and avocados worldwide. A study in Investigative Ophthalmology & Visual Science affirms Vitamin E’s benefits for eye health. https://iovs.arvojournals.org

Global Sources of Vitamin E:

Nigeria and West Africa: Groundnuts (peanuts), palm oil, and sunflower seeds. United States and Europe: Almonds, sunflower oil, and hazelnuts. Universal Superfood: Avocados, rich in Vitamin E and found globally.

Putting It All Together: A Vision-Healthy Diet

A balanced diet incorporating a variety of nutrient-rich foods is essential for eye health. For breakfast, consider scrambled eggs with spinach and tomatoes. Lunch could feature grilled tilapia with steamed kale and yellow maize. Snack on guava slices and a handful of cashews. End the day with baked salmon, avocado salad, and roasted sweet potatoes for dinner. Regardless of regional differences in foods such as fluted pumpkin leaves in Nigeria or kale in the United States, the nutrients they provide are universal.

Why Social Sciences Are Far From Obsolete: Lessons From My International Relations Studies in the UK

In a recent Facebook post, a social commentator argued that social science courses like sociology, anthropology,  political science, and international relations among others are no longer relevant in today’s labor market, emphasizing the need for tangible and technical skills to survive the 21st-century economy. This has caused ripples and elicited mixed reactions from many quarters, especially on social media platforms. While his concern about the employability of graduates including those who studied non-social science courses (my emphasis)  is valid, particularly in Nigeria's saturated labor market, dismissing the relevance of social sciences reflects a misunderstanding of their role in addressing societal needs. Because employability challenges in Nigeria transcend disciplines; even technical fields like engineering are not exempt, as evidenced by cases like the Dangote Refinery’s reliance on foreign technicians. The deeper problem here is the disconnect between the produc...
